At a scout jamboree, dinner is served from tinned food. each tin of soup is shared between 2 scouts. each tin of frankfurters is shared between 3 scouts and each tin of fruit is shared between 4 scouts. if 117 tins are opened to feed all the scouts, how many scouts attended the jamboree

Answers

Answer 1

By answering the above question, we may state that As a result, there equation were 108 scouts who attended the jamboree.

What is equation?

A math equation is a mechanism for connecting two claims by using the equals sign (=) to indicate equivalence. A mathematical statement that establishes the equivalence of two mathematical expressions is known as an equation in algebra. The equal symbol, for example, splits the numbers 3x + 5 and 14. A mathematical formula can be used to describe the relationship between two phrases written on opposite sides of a letter. The logo and programme are frequently the same. 2x - 4 Equals 2, for example.  

Because each tin is divided by four scouts, the number of fruit tins necessary will be one-fourth of the number of scouts. As a result, the quantity of tins of fruit required is x/4.

The total number of tins opened, according to the query, is 117. Based on the preceding data, we can construct the following equation:

x/2 + x/3 + x/4 = 117

To remove the denominators, multiply both sides by 12 (the LCM of 2, 3, and 4).

6x + 4x + 3x = 1404

When we simplify, we get:

13x = 1404

By multiplying both sides by 13, we get:

x = 108

As a result, there were 108 scouts who attended the jamboree.

5. Claude is wrapping cylindrical bug spray containers in tissue paper to put them inside a box.

Each container has a height of 12. 7 centimeters and a radius of 3 centimeters.

If he is wrapping a total of 5 bug spray containers, how many square

centimeters of tissue paper will he need?

Answers

Claude will need approximately 1202.3 square centimeters of tissue paper for wrapping a total of 5 bug spray containers.

To calculate the amount of tissue paper needed, we need to find the lateral surface area of one cylinder and then multiply it by the number of cylinders being wrapped.

The lateral surface area of a cylinder can be found using the formula 2πrh, where r is the radius and h is the height of the cylinder. In this case, r = 3 cm and h = 12.7 cm.

Lateral surface area of one cylinder = 2π(3 cm)(12.7 cm) = 239.38 cm² (rounded to two decimal places)

Since Claude is wrapping 5 bug spray containers, we need to multiply the lateral surface area of one cylinder by 5:

Total tissue paper needed = 5 × 239.38 cm² = 1196.9 cm²

Therefore, Claude will need approximately 1202.3 square centimeters of tissue paper.

Answers

The value of f(15) is approximately 346.42.

What is an exponential function?

An exponential function is a mathematical function of the form f(x) = abˣ, where a and b are constant and b is greater than zero and not equal to 1. An example is f(x) = 2ˣ

We can use the properties of exponential functions to find the value of f(15). Since f(x) is an exponential function, we can write it in the form:

f(x) = a × bˣ

f(4.5) = 16 = a × b⁴.5

f(9.5) = 60 = a × b⁹.5

Dividing second equation by first equation gives:

f(9.5)/f(4.5) = (a × b⁹.5)/(a × b⁴.5) = b⁵

Substituting the given values, we get:

60/16 = b⁵

b = (60/16)¹/⁵

b ≈ 1.46

Substituting b into the first equation gives:

16 = a × 1.46⁴.5

a ≈ 0.30

Therefore, the exponential function is:

f(x) = 0.30 × 1.46ˣ

To find f(15), we can substitute x = 15 into the function:

f(15) = 0.30 × 1.46¹⁵

In ΔLMN, m = 5. 9 cm, n = 8. 7 cm and ∠L=163°. Find the length of l, to the nearest 10th of a centimeter

Answers

Using the Law of Cosines the length of l, to the nearest 10th of a centimeter is 4.6 cm.

To find the length of side l in triangle LMN, we can use the Law of Cosines, which states that c² = a² + b² - 2ab cos(C), where c is the side opposite the angle C.

In this case, we have:

a = 5.9 cm

b = 8.7 cm

C = 163°

First, we need to convert the angle from degrees to radians by multiplying it by π/180:

C = 163° × π/180 = 2.847 radians

Now we can plug in the values into the Law of Cosines:

l² = 5.9² + 8.7² - 2(5.9)(8.7)cos(2.847)

Simplifying the right-hand side:

l² = 68.81 - 60.83 × cos(2.847)

Taking the square root of both sides:

l ≈ 4.6 cm

Therefore, the length of l to the nearest 10th of a centimeter is 4.6 cm.

4)No real solutions

1) Equation for a line perpendicular to y=2x+3 and passing through the point (4-6)A line perpendicular to y = 2x + 3 would have a slope of -1/2 (the negative reciprocal of 2). To find the equation of the line, we use point-slope form. We substitute the point (4, -6) and the slope of -1/2:We know that the line must pass through the point (4, -6) and be perpendicular to the line y = 2x + 3, so we can write its equation in point-slope form as follows:y - (-6) = (-1/2)(x - 4)y + 6 = (-1/2)x + 2The answer is y + (1/2)x = 2.

2) Multiplying the complex numbers (11-3i)(7-12i)We will be using the FOIL method (first, outer, inner, last) for multiplying two binomials:First, we multiply 11 and 7 to get 77.Then, we multiply 11 and -12i to get -132i.Next, we multiply -3i and 7 to get -21i.Last, we multiply -3i and -12i to get 36i² (remembering that i² is equal to -1).Finally, we combine like terms:77 - 132i - 21i + 36i² = 77 - 153i - 36 = -59 - 153iThe answer is -59 - 153i.

3) Dividing complex numbers (185-72i) divided by (11+10i)To divide complex numbers, we need to multiply the numerator and denominator by the conjugate of the denominator (in which the sign of the imaginary part is changed):We multiply the numerator and denominator by the conjugate of 11 + 10i, which is 11 - 10i in this case, to eliminate the imaginary part from the denominator:(185 - 72i)(11 - 10i) = (185 × 11 - 72i × 11) - (185 × 10i + 72i × 10i) = (2035 - 792i) - (1850i + 720i²)Simplifying, we get:(2035 - 792i) - (1850i + 720i²) = (2035 - 792i) - (1850i + 720(-1)) = (2035 - 792i) - (1850i - 720) = 1315 - 62iThe answer is 1315 - 62i.

4) Solving an equation by completing the square: y² - 6y + 19 = 5First, we isolate the y terms and move the constant to the other side:y² - 6y + 14 = 0Next, we divide both sides by the leading coefficient (1 in this case):y² - 6y = -14To complete the square, we take half the coefficient of y, square it, and add it to both sides. In this case, that's (-6/2)² = 9:y² - 6y + 9 = -5Now, we factor the left-hand side as a perfect square:(y - 3)² = -5Finally, we take the square root of both sides:(y - 3) = ±√(-5)This expression has no real solutions because the square root of a negative number is imaginary.

working together, shayna and huong can clean an attic in 6.16 hours. had she done it alone it would have taken huong 11 hours. find how long it would take shayna to do it alone

Answers

Working together, Shayna and Huong can clean an attic in 6.16 hours. Had she done it alone, it would have taken Huong 11 hours. Therefore, Shayna can clean the attic alone in 80 hours.

Let's denote the amount of work to be done by x units. The work done by Shayna in one hour is y.

Shayna and Huong work together for 6.16 hours, so in one hour they do 1/6.

16 of the work together.According to the problem:

x/6.16 = 1/6.16 units per hour

Therefore, the amount of work done by Huong in one hour is (x/11).

Now, we can express the amount of work done by Shayna and Huong in one hour as:

(x/11) + y = 1/6.16

To determine the value of y, we can solve the above equation. Solving the equation:

(x/11) + y = 1/6.16y = (1/6.16) - (x/11)y = (11-6.16x)/(11 × 6.16)

So the amount of work done by Shayna in one hour is y = (11-6.16x)/(11 × 6.16).

To find how long it would take Shayna to do it alone, we have to express the amount of work done by Shayna alone in one hour as x/h.

Using the unitary method we have:

x/h = yx/h = (11-6.16x)/(11 × 6.16)

hx = 11 × 6.16 - 6.16x

hx + 6.16x = 11 × 6.16

hx = (11 × 6.16)/0.84 = 80 hours

What is area and volume?

A flat, two-dimensional object's area is the space it takes up in a plane. A three-dimensional object's volume is the area it takes up in space.

We know that

Curved surface area = 2πrh

So, using this we get

⇒Curved surface area = 2 × 3.14 × 14 ×25

⇒Curved surface area = 2,198 square centimeter

Similarly,

Total surface area = 2πr (r + h)

So, using this we get

⇒Total surface area = 2 × 3.14 × 14 (14 + 25)

⇒Total surface area = 2 × 3.14 × 14 (39)

⇒Total surface area = 3,428 square centimeter

Similarly,

Volume = π[tex]r^{2} h[/tex]

So, using this we get

⇒Volume = 3.14 × [tex]14^{2}[/tex] × 25

Step-by-step explanation:

First, we can simplify both sides of the equation by combining like terms:

2b + 8 - 5b + 3 = -13 + 8b - 5

-3b + 11 = 8b - 18

Next, we can isolate the variable term on one side of the equation by adding 3b to both sides:

-3b + 3b + 11 = 8b - 18 + 3b

11 = 11b - 18

Then, we can isolate the variable term again by adding 18 to both sides:

11 + 18 = 11b - 18 + 18

29 = 11b

Finally, we can solve for b by dividing both sides by 11:

29/11 = b

b ≈ 2.636

Therefore, the solution to the equation is b ≈ 2.636.

Answer:

b = 29/11

A system of equations is what?

A group of two or more equations that must be solved all at once is known as a system of equations. The values of the variables in a system of equations that make all of the equations in the system true are known as the solutions. Several approaches, including substitution, elimination, and graphing, can be used to solve systems of equations. Several branches of mathematics, science, and engineering employ systems of equations to represent and solve issues that arise in the real world.

Let us suppose the two numbers = a and b.

Thus, from the given statement we have:

a + 2b = 20 (Equation 1)

and

ab ≤ 48 (Equation 2)

Using equation 1:

a = 20 - 2b

Substituting this expression for "a" into Equation 2, we get:

(20 - 2b)(b) ≤ 48

-2b² + 20b - 48 ≤ 0

b² - 10b + 24 ≥ 0

This inequality can be factored as:

(b - 4)(b - 6) ≥ 0

Since we want the product of the two numbers to be less than or equal to 48, both "a" and "b" must be positive.

We only need to consider the values of "b" that make this inequality true:

b ≤ 4 or b ≥ 6

Plug each of these values of "b" back into Equation 1:

When b = 4, we get:

a + 2(4) = 20

a = 12

When b = 6, we get:

a + 2(6) = 20

a = 8

Therefore, the possible values of "a" are 8 and 12.

If the volume of a cylinder is given, the dimensions of cylinder can be written and r = √(V/(πh)) and h = V/(πr²)

The volume of a cylinder is given, find dimensions of cylinder. To find the dimensions of a cylinder given its volume, we need to know either the radius or height. The formula for the volume of a cylinder is:

V = πr²h

where V is the volume, r is the radius, and h is the height.

If we are given the volume V, we can solve for either r or h as follows:

If we solve for the radius r:

V = πr²h

r² = V/(πh)

r = √(V/(πh))

If we solve for the height h:

V = πr²h

h = V/(πr²)

Bea earned $11,700 commission for selling a house, calculated as 6100 of the selling price. What was the selling price of the house?

Answers

The selling price of the house was approximately $1.918 or rounded to the nearest dollar, $19,180.

How to find the selling price?

We can start by setting up an equation to represent the problem. We know that the commission Bea earned is equal to 6100 of the selling price, which can be expressed as:

commission = 6100 × selling price

We also know that the commission Bea earned was $11,700, so we can substitute that into the equation:

11,700 = 6100 × selling price

Now we can solve for the selling price by dividing both sides by 6100:

selling price = 11,700 ÷ 6100

The independent variable is the one that can be freely chosen or manipulated, and which affects the dependent variable. In this case, Colette has control over how many cucumbers she grows, and the number of pickles she can make is affected by the number of cucumbers she has. Therefore, the number of cucumbers is the independent variable, and the number of pickles is the dependent variable.

Answer:

First, we need to find the slope and y-intercept of the linear regression line:

Using a calculator or statistical software, we get:

Slope (b) = 0.621

Y-intercept (a) = 50.4

Therefore, the linear regression equation is:

y = 0.6x + 50.4

To find the projected test grade for a student with a homework grade of 45, we substitute x = 45 into the equation:

y = 0.6(45) + 50.4

y = 27 + 50.4

y = 77.4

Rounding to the nearest integer, the projected test grade for a student with a homework grade of 45 is 77.

What is the equation of the circle below?

Answers

The equation of the given circle is (x-2)² + (y+1)² = 9.

What is a Circle?

In mathematics Round and in two dimensions, a circle is a figure. The circle's center is a place inside the circle from which all points on the circle's edge are equally far.

The radius of the circle, abbreviated "r," is the distance from the center of the circle to a point on its edge. The diameter of the circle, which is the greatest chord of any circle, is equal to the circle's doubled radius.

We know that, equation of a circle is given by :

(x-h)² + (y-k)² = r²

where, (h, k) are coordinates of the center of circle.

Here, the coordinates of center of circle is (2,-1) and the radius is 3 units.

So, equation of given circle :

(x-h)² + (y-k)² = r²

(x-2)² + (y+1)² = 3²

(x-2)² + (y+1)² = 9

An accounting firm agrees to purchase a computer for $120,000 (cash on delivery) and the delivery date is in 270 days. How much do the owners need to deposit in an account paying 0. 65% compounded quarterly so that they will have $120,000 in 270 days?

Answers

The owners need to deposit in an account paying 0. 65% compounded quarterly so that they will have $120,000 in 270 days is $119,262.94

To calculate the amount the owners need to deposit today, we can use the formula for compound interest:

A = [tex]P(1 + r/n)^{(nt)}[/tex]

where:

A is the future value of the investment

P is the principal amount (the amount to be deposited)

r is the annual interest rate (0.65%)

n is the number of times the interest is compounded per year (4 for quarterly)

t is the time in years (270 days/365 = 0.7397 years)

Substituting the values given into the formula, we get:

$120,000 = [tex]P(1 + 0.0065/4)^{4\times0.7397}[/tex]

$120,000 = [tex]P(1.001625)^{2.9588}[/tex]

$120,000 = P(1.004845)

P = $120,000/1.004845

P = $119,262.94

Therefore, the owners need to deposit $119,262.94 in an account paying 0.65% compounded quarterly so that they will have $120,000 in 270 days.

Answers

The solution to the inequality 5x - 6 <4 + 6x is x > -10

How to determine the solution to the inequality

From the question, we have the following parameters that can be used in our computation:

5x - 6 <4 + 6x

Subtract -6 from both sides of the inequality expression

So, we have the following representation

5x < 10 + 6x

Subtract 6x from both sides of the inequality expression

So, we have the following representation

-x < 10

Divide by -1

x > -10

So, the solution is x > -10

What is Trigonometric Functions?

Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.

y=tanx

dy/dx = dy/dx = cos x.cos x - sin x(-sin x) / cos² x

⇒ dy/dx = (cos² x + sin² x) / cos² x

⇒ dy/dx = 1 / cos²x

⇒ dy/dx = sec²(x)

Thus, the derivative of y = tan(x) is sec²(x).

cot^2(135-b) if sin2b=-1/5

Answers

Therefοre, the sοlutiοn οf the given prοblem οf trigοnοmetry cοmes οut tο be cοt²(135-b) = 3.

A Trigοnοmetry is what?

Relatiοnships between cubic splines and maths variable astrοphysics is believed tο have been created when the variοus fields came tοgether. Many metric prοblems can be sοlved triangle οr the results οf their calculatiοn can indeed be determined with the help οf precise mathematical methοds. Trigοnοmetry is the study οf six basic trigοnοmetric calculatiοns. They gο by a variety οf titles and acrοnyms, including sine, deviatiοn, angle, and sο fοrth (csc).

Here,

First, we need tο find the value οf cοs(b) using the given infοrmatiοn that sin(2b) = -1/5:

=> sin(2b) = 2sin(b)cοs(b)

=> -1/5 = 2sin(b)cοs(b)

We knοw that sin^2(b) + cοs^2(b) = 1, sο we can rearrange this equatiοn tο sοlve fοr cοs(b):

=> cοs²(b) = (1 - sin²(b))

Substituting this intο the equatiοn we fοund abοve:

=> -1/5 = 2sin(b)cοs(b)

=> -1/5 = 2sin(b)√(1 - sin²(b))

Squaring bοth sides and simplifying:

=> 1/25 = 4sin²(b)(1 - sin²(b))

=> 1/25 = 4sin²(b) - 4sin²(b)

=> 4sin²(b) - 4sin²(b) + 1/25 = 0

We can sοlve fοr sin^2(b) using the quadratic fοrmula:

sin²(b) = [4 ± √(16 - 4(4)(1/25))] / (2(4))

sin²(b) = [4 ± 2/5] / 8

sin²(b) = 3/10 οr 1/20

Since sin(2b) is negative, we knοw that sin(b) is negative as well, sο sin²(b) = 3/10. Therefοre:

cοs²(b) = 1 - sin²(b) = 1 - 3/10 = 7/10

Nοw we can use the identity

=> cοt²(θ) = 1 / [tan²(θ)] tο find cοt²(135-b):

1 / [tan(135-b)] = cοt(135-b)

By applying the fοrmula tan(x) = sin(x) / cοs(x):

=> tan(135-b) Equals cοs(135-b) / sin(135-b) (135-b)

The identities sin( + 90) = cοs() and cοs( + 90) = -sin() are used tο illustrate:

=> Cοs(90-b) = sin(135-b) = sin(45 + (90-b)) = sin (b)

=> Sin(90-b) = cοs(135-b) = cοs(45 + (90-b)) = cοs (b)

Using these numbers in place οf:

=> 1/tan(135-b) = sin(b) / cοs(b) (3)

=> 1 / [tan(135-b)] = cοt(135-b) = 1 / [(-1/√(3))²] = 3

Cοnsequently, cοt2(135-b) = 3.
