The perimeter of a rectangular table is 18 feet The table is 42 inches wide

Answers

Width of the table = 3.5 feet , Length of the table = 5.5 feet and Perimeter of the table = 18 feet

What is Rectangle ?

A rectangle is a 2-dimensional shape with four straight sides, where opposite sides are parallel and equal in length. It has four right angles and its diagonals bisect each other. It is a type of quadrilateral, and its area is calculated by multiplying the length and width of the rectangle. It is commonly found in many geometric shapes and everyday objects such as doors, windows, and computer screens.

Let's convert all measurements to the same unit for easier calculation. Since the table width is given in inches, we can convert it to feet by dividing by 12 (since 1 foot = 12 inches).

Table width: 42 inches = 42÷12 = 3.5 feet

Let's denote the length of the table as 'l' feet. The perimeter of a rectangle is given by the formula:

Perimeter = 2 * (Length + Width)

Given that the perimeter is 18 feet, we can substitute the values into the formula:

18 = 2 * (l + 3.5)

Now, we can solve for 'l':

18 = 2l + 7 (distributing 2 to both terms in the parentheses)

2l = 18 - 7 (subtracting 7 from both sides)

2l = 11 (simplifying)

l = 11÷2 (dividing both sides by 2)

Therefore, Width of the table = 3.5 feet , Length of the table = 5.5 feet

and Perimeter of the table = 18 feet

The last time Ms. Ward's car tank was filled, the odometer reading was 7,998 miles. The next time she filled up her vehicle with gas, the odometer reading was 8,308.

What was Ms. Ward's cost per mile for the time period? (remember, money always rounds to 2 decimal places!)

Answers

Answer:

$0.14

Step-by-step explanation:

[tex]8,308 - 7,998 = 310 \: miles[/tex]

We don't have information on how many gallons of gas Ms. Ward purchased, so we can't calculate the exact cost per mile. However, we can use the average fuel efficiency of her car to estimate the cost. Let's assume her car gets an average of 25 miles per gallon, which is a common fuel efficiency for a compact car.

To calculate how many gallons of gas she used, we can divide the number of miles driven by the fuel efficiency:

[tex]\frac{310 \: miles}{25 \: miles _{gallon} } = 12.4 \: gallons[/tex]

Assuming that the cost of gas was $3.50 per gallon, we can multiply the number of gallons used by the cost per gallon to find the total cost of gas:

[tex]12.4 \: gallons \times $3.50_{gallon} = $43.40[/tex]

To find the cost per mile, we can divide the total cost of gas by the number of miles driven:

[tex]\frac{$43.40}{310 \: miles} = $0.14_{mile} [/tex]

So Ms. Ward's cost per mile for this time period was approximately $0.14.

Answer:

Step-by-step explanation:

Miles travelled = 8,308 - 7,998 = 310 miles

Total cost = $26.79

Cost per mile[tex]=\frac{26.79}{310}[/tex] =0.0864

The sum of the first 10 terms in the sequence is 195.The sequence given above is an arithmetic sequence.

What is an arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each successive number is found by adding a fixed number, called the common difference, to the previous number in the sequence. The common difference is the same for each pair of consecutive numbers.

An arithmetic sequence is a sequence of numbers where each successive number is obtained by adding a fixed amount, the common difference, to the preceding number. In this particular sequence, the common difference is 5.

The first term in the sequence is a₁ = -3, and the general term is an = 3an-1 + 5, where n > 2. To find any term in the sequence, we can use the formula an = a₁ + (n - 1)d, where d is the common difference. In this case, a₁ = -3 and d = 5, so the formula becomes an = -3 + (n - 1)5.

To find the 9th term in the sequence, we can substitute n = 9 into the above formula and solve for an. This gives us an = -3 + (9 - 1)5 = -3 + 40 = 37. Therefore, the 9th term in the sequence is 37.

To find the sum of the first 10 terms in the sequence, we can use the formula Sₙ = (n/2)(2a₁ + (n - 1)d). In this case, a₁ = -3 and d = 5, so the formula becomes Sₙ = (n/2)(2(-3) + (n - 1)5). Substituting n = 10 into the formula gives us Sₙ = (10/2)(2(-3) + (10 - 1)5) = (10/2)(-6 + 45) = (10/2)(39) = 195. Therefore, the sum of the first 10 terms in the sequence is 195.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right triangles. It is used to study and analyze various phenomena that involve periodic functions, such as waves, oscillations, and sound. Trigonometry also has practical applications in fields such as physics, engineering, navigation, and surveying. It involves the use of trigonometric functions such as sine, cosine, tangent, cosecant, secant, and cotangent to calculate the sides and angles of triangles and other geometric figures.

Here,

Let's solve for θ:

First, let's substitute u = cos(θ), so we have:

3u² - 5u - 4 = 0

Now we can use the quadratic formula:

u = [ -(-5) ± √((-5)² - 4(3)(-4))] / (2*3)

u = [ 5 ± √(49) ] / 6

u1 = (5 + 7) / 6 = 2

u2 = (5 - 7) / 6 = -2/3

Since the cosine function has a range of -1 ≤ cos(θ) ≤ 1, we can discard the solution u1 = 2.

Now we can solve for θ:

cos(θ) = u2 = -2/3

θ = cos⁻¹(-2/3) ≈ 131.81°  

θ = 360° - cos⁻¹(-2/3) ≈ 228.19°

The surface area of the box shown is 186 square inches (186 in²).

What is surface area?

Surface area is the measure of the area on a two-dimensional surface. It is the sum of the areas of all the shapes that make up a two-dimensional object. It can be used to calculate the area of a sphere, a cylinder, a rectangular prism, and more.

The box shown is a three-dimensional rectangular prism. The surface area (S.A.) of a rectangular prism is calculated by adding the area of each of its six faces. The area of each face is calculated by multiplying the length of the face by its width.

For the box shown, the length is 3 inches (3 in), the width is 12 inches (12 in), and the height is 10 inches (10 in). To find the surface area, we need to calculate the area of each face and add them together. The surface area of this box is calculated as follows:

Front and back faces: 3 in x 10 in = 30 in²

Left and right faces: 12 in x 10 in = 120 in²

Top and bottom faces: 3 in x 12 in = 36 in²

Total surface area: 30 in² + 120 in² + 36 in² = 186 in²

Therefore, the surface area of the box shown is 186 square inches (186 in²).

Solving Square Root Equations



Solve the following equations. Be sure to label any extraneous solutions.

Answers

Answer:

Step-by-step explanation:

1) To solve the equation √(6x) = x, we can first square both sides of the equation to eliminate the square root:

(√(6x))^2 = x^2

6x = x^2

Next, we can rearrange the equation into standard quadratic form by subtracting 6x from both sides:

x^2 - 6x = 0

Now, we can factor out an x from the left-hand side of the equation:

x(x - 6) = 0

Setting each factor equal to zero, we find two solutions:

x = 0 or x - 6 = 0

Therefore, the solutions to the equation √(6x) = x are x = 0 and x = 6.

2)To solve √(5x-6) = x, we can square both sides of the equation:

(√(5x-6))^2 = x^2

5x-6 = x^2

Rearranging this quadratic equation to the standard form ax^2 + bx + c = 0, we get:

x^2 - 5x + 6 = 0

This can be factored into:

(x - 2)(x - 3) = 0

Therefore, the solutions to the equation √(5x-6) = x are x = 2 and x = 3.

We should check if these solutions satisfy the original equation:

When x=2: √(5x-6) = √(5(2)-6) = √4 = 2, which satisfies the equation.

When x=3: √(5x-6) = √(5(3)-6) = √9 = 3, which also satisfies the equation.

Therefore, the solutions are x = 2 and x = 3.

3) To solve the equation √(2x-1) = x-3, we can square both sides of the equation to eliminate the square root:

(√(2x-1))^2 = (x-3)^2

Simplifying the left-hand side gives:

2x-1 = (x-3)^2

Expanding the right-hand side gives:

2x-1 = x^2 - 6x + 9

Rearranging the equation gives:

x^2 - 8x + 10 = 0

We can solve this quadratic equation :

x^2 - 8x + 10 = 0

Now we can solve this quadratic equation by using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 1, b = -8, and c = 10. Substituting these values into the formula:

x = (-(-8) ± √((-8)^2 - 4(1)(10))) / 2(1)

Simplifying:

x = (8 ± √(64 - 40)) / 2

x = (8 ± √24) / 2

x = 4 ± √6

Therefore, the solutions to the equation √(2x - 1) = x - 3 are x = 4 + √6 and x = 4 - √6.

4) has no real solutions.

when you have to remove the square root you have to power the both sides of the equation.

what is function?

Mathematicians investigate numbers and their variants, equations and associated structures, forms and their locations, and prospective locations for these things. The term "function" refers to the relationship between a group of inputs, each with its own output. A function is a connection of inputs and outputs in which each input results in a single, distinct outcome. Each function has its own domain, codomain, or scope. The letter f is commonly used to denote functions (x). An x represents entry. On functions, one-to-one capabilities, so multiple capabilities, in capabilities, and on functions are the four basic types of accessible functions.

The volume of the PVC pipe can be estimated by subtracting the volumes of the outer and inner cylinders:

V = π/4 × (D² - d²) × L

where V denotes volume, is the mathematical constant pi (roughly equivalent to 3.14159), D denotes outer diameter, d denotes inner diameter, and L denotes pipe length.

V = π/4 × (6.5² - 5²) × 30\sV = 531.13 cm³

PVC pipe mass can be estimated by multiplying its volume by its density:

m = V × ρ

With the provided density, we get:

1.38 g/cm3 m = 733.48 g m = 531.13 cm3

Let's use variables to represent the width and length of the rectangle:

Let w be the width of the rectangle (in cm)

Then, the length of the rectangle can be expressed as 5w - 18 (since it is 18 cm less than five times its width).

The area of the rectangle can be calculated as:

A = w * (5w - 18)

We are given that the area of the rectangle is 35 square cm. Substituting this value into the equation above, we get:

35 = w * (5w - 18)

Expanding the right-hand side, we get:

35 = 5w^2 - 18w

Rearranging the terms and setting the equation equal to zero, we get:

5w^2 - 18w - 35 = 0

To solve for w, we can use the quadratic formula:

w = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 5, b = -18, and c = -35.

Plugging in the values, we get:

w = (-(-18) ± sqrt((-18)^2 - 4(5)(-35))) / 2(5)

w = (18 ± sqrt(784)) / 10

w = (18 ± 28) / 10

So w = 2.6 or w = -1.4

Since the width cannot be negative, we reject the solution w = -1.4.

Therefore, the width of the rectangle is approximately 2.6 cm.

To find the length, we can use the expression we derived earlier:

length = 5w - 18

length = 5(2.6) - 18

length = 13 - 18

length = -5

Since the length cannot be negative, we know that there is an error in our calculation. We made an assumption that the width is less than the length, which is not necessarily true. We should check our work and try again using the positive root instead of the negative one.

Using the positive root for the width, we get:

w = (18 + 28) / 10

So w = 4.6

Therefore, the width of the rectangle is 4.6 cm.

To find the length, we can use the expression we derived earlier:

length = 5w - 18

length = 5(4.6) - 18

length = 23 - 18

length = 5

So the length of the rectangle is 5 cm.

Therefore, the dimensions of the rectangle are width = 4.6 cm and length = 5 cm.

The circles have the same center. What is the area of the shaded region?

Answers

Answer: 160.14

Explanation: the inner circle has an area of 153.86 in.^2. The outer circle as a whole has an area of 314 in.^2. Subtract the area of the inner circle(153.86) from the area of the total of the bigger circle(314) to get the area of the shaded region of the circle.

Answer:

The area of the shaded region is 160.2 in² (to the nearest tenth).

Step-by-step explanation:

The area of the shaded region can be calculated by subtracting the area of the inner circle from the area of the outer circle.

[tex]\boxed{\begin{minipage}{4 cm}\underline{Area of a circle}\\\\$A=\pi r^2 $\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\\end{minipage}}[/tex]

If the circles have the same center, and the inner circle has a radius of 7 in, then the outer circle has a radius of:

[tex]\implies r = 7 + 3 = 10\; \sf in[/tex]

Therefore, the area of the shaded region is:

[tex]\begin{aligned}\sf Area_{shaded\;region}&=\sf Area_{outer\;circle}-Area_{inner\;circle}\\&=\pi \cdot 10^2 - \pi \cdot 7^2\\&=100\pi - 49 \pi\\&=51 \pi\\& = 160.221225...\\&=160.2\; \sf in^2\;(nearest\;tenth)\end{aligned}[/tex]

What is an Expression?

In mathematics, an expression is a combination of numbers, variables, and mathematical operations that can be evaluated or simplified. An expression may contain one or more terms, which are separated by operators such as addition (+), subtraction (-), multiplication (*), division (/), and exponentiation (^).

Expressions can represent various mathematical concepts, such as equations, inequalities, functions, and polynomials.

Given:  m = -7 and n = 2,

We know that, the mode function converts the function into positive value.

So, |m - n| = |-7 - 2| = 9

Now,

4 |m - n| = 4 * 9 = 36

So the expression 4 |m - n| evaluates to 36 when m = -7 and n = 2.

A ship travels east from Port Lincoln 24 miles before turning north. When the ship becomes disabled
and radios for help, the rescue boat needs to know the fastest route to the ship. The rescue boat navigator
finds that the shortest route from Port Lincoln is 48 miles long. At what angle off of due east should the
rescue boat travel to take the shortest route to the ship? Round your answer to the nearest whole degree.

Answers

Answer:

Rounding to the nearest whole degree, the rescue boat should travel at an angle of approximately 41 degrees off of due east to take the shortest route to the ship.

Step-by-step explanation:

We can use trigonometry to solve this problem. Let's draw a diagram to represent the situation:

            A (rescue boat)

              | \

              |   \

              |     \ C (disabled ship)

   24 mi |       \

              |        \

              |          \

              |θ          \

              B-----------D (Port Lincoln)

               48 mi

In the diagram, point B represents Port Lincoln, point C represents the disabled ship, and point A represents the rescue boat. Point D is the intersection of the eastward path and the northward path taken by the ship.

We are given that BD = 24 miles and CD = 48 miles. We want to find the angle θ, which is the angle between the line segments AB and AD.

To find θ, we can use the law of cosines:

cos(θ) = (BD² + CD² - AD²) / (2 x BD x CD)

Substituting the given values, we get:

cos(θ) = (24² + 48² - AD²) / (2 x 24 x 48)

Simplifying, we get:

cos(θ) = 0.75

To solve for θ, we can take the inverse cosine of both sides:

θ = cos⁻¹(0.75)

Using a calculator, we get:

θ ≈ 41.41°

Rounding to the nearest whole degree, the rescue boat should travel at an angle of approximately 41 degrees off of due east to take the shortest route to the ship.

A light display for a festival consists of a string of 1,000 lightbulbs in the colors red, yellow, green, and blue repeated consecutively in that order for the entire display. The 543rd lightbulb needs to be replaced.

If the first lightbulb is red, what is the color of the lightbulb that needs to be replaced?

Answers

Using the pattern given, we found that the colour of the lightbulb in the 543rd position of a string of lightbulbs is green.

What is meant by the pattern?

A recurring arrangement of numbers, shapes, colours and other elements is known as a pattern. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series. The number of patterns can be limitless or finite. There are many distinct kinds of number patterns, including geometric, Fibonacci, and algebraic or arithmetic patterns. In mathematics, number patterns are quite prevalent.

Given,

The number of lights on a string of lights = 1000

The order in which the lights repeat is red, yellow, green and blue.

After every four lights, the order repeats.

We can get the pattern as follows.

The blue lights are in positions 4,8,12,........,4n.

We have to find the multiple of 4 close to 543.

Now we can check if 542 is a multiple of 4.

542/4 = 135.5

So it is not a multiple of 4.

Now check if 544 is a multiple of 4.

544/4 = 136

So the bulb in the 544th position is blue.

Then the bulb in the 543rd position should be green.

Therefore using the pattern given, we found that the colour of the lightbulb in the 543rd position of a string of lightbulbs is green.
