Answer:

9 and 3/5 hours or 9 hours and 36 minutes

Step-by-step explanation:

Rate x times = number of jobs

Jemuel's rate is 1 job/ 16 hours.

Lemuels's rate is 1 job/12 hours.

1/16T + 1/14T = 1  Get a common denominator of 48

3/48T + 2/48 t = 1

5/48T = 1  Multiply both sides by 48/5

(45/5)(5/48)T = 1(48/5)

t = 48/5 = 9 3/5 hours.

If the overall percentage of the defective panels from the two plants is 5% then plant B produced 4000 panels in total.

This question can be solved by formulating the problem into the form of a linear equation having two variables. Linear equation in two variables can be represented in the form of ax+by+c=0 where a, b and c are real numbers and x, y are variables or the coefficients, and a, b ≠ 0.

Let the production from plant A be x, and according to the question x=10000.

Also, let the production from plant B be y.

Now, as 3% of products are found defective from plant A and 10% of products are found defective from plant B and overall defective products is 5%.

Thus, 0.03x+0.1y=0.05(x+y)

As x=10000 then

0.03×10000+0.1y=0.05(10000+y)

300+0.1y=500+0.05y

0.05y=200

=>y=4000

Thus, the total number of panels produced by plant B is equal to 4000.

The two integers which the length of one side is in between are 72 yards and 73 yards

The given parameters are

Area = 5280 square yards

Shape = Square

The area of a shape is calculated using

Area = Length^2

So, we have

Length^2 = 5280 square yards

Take the square root of both sides

Length = 72.66 yards

72.66 yards is between 72 yards and 73 yards

Hence, the two integers which the length of one side is in between are 72 yards and 73 yards

If a right triangular prism's height is 1 inch. The produced solid has the following surface area: = 2,930.05 in².

A polyhedron with six vertices, nine edges, and five faces is a right triangular prism. Regular prisms have all of their triangles faces equilateral. The prism's rectangular faces will be congruent in this situation.

A triangular prism's total surface area is the sum of the areas of its three lateral faces (rectangles) as well as two bases (triangles). For something like the surface area of any prism, the most generic formula is:

Given:

Hight = 1 inches

Base of the prism = 10 inches.

The Hight if the base = 82 inches.

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)

Surface area = 5(10× 10) + (0.5÷ 10 × 1) + 3(10× 82)

Surface area = 5(100) +0.05+ 3(810)

Surface area = 500 +0.05 + 2430

Surface area = 2,930.05 in²

The produced solid has a surface area of approximately = 2,930.05 in².

The compound inequality is  60 < n < 104.

Let 'x' denote the amount of money saved by Julian.

Then x is between $30 and $52.

I.e., x>30 and x<52.

This can be written as a single inequality by combining the both.

i.e., 30 < x < 52

His friend Daniela saved twice as much as Julian.

Let 'n' denotes the amount of money Daniela saved.

Then n = 2x

We need to write the compound inequality for the money saved by Daniela.

As Daniela saved twice as much as Julian, it will be between 2 x 30 = $60 and 2 x 52 = $104

Value for  the 3 straight  lines are 180,28 , 152.

What is a straight line, exactly?

Simply put, a straight line is a line devoid of bends. A straight line is one that does not curve and reaches to infinity on both sides.

CBE = 28 + 90 = so the angle is 118 degrees

ABF = you already got the answer written down, 28

CBA = this is not 180 like you wrote, CBA = ABD - CBD

Straight lines = 180, so ABD = 180

You already found out that CBD = 28

so CBA = 180 - 28 so the answer CBA = 152

a. 55% of the maximum weight is 33 pounds.

b. 114 pounds is 190% of the weight limit.

c. 57 pounds is 95% of the maximum.

Answer to Part a:

Let c be the weight limit percentage for 33 pounds.

Then we have (60 x c)/100 = 33 pounds

This implies 3c/5 = 33

This means that 3c = 33 x 5 = 165.

This means that c = 165 / 3 = 55.

Therefore 55% of the weight limit is 33 pounds.

Answer to Part b:

Let d be the weight limit percentage for 114 pounds.

Then we have (60 x d)/100 = 114 pounds

This implies 3d/5 = 114

This means that 3d = 114 x 5 = 570.

This means that d = 570 / 3 = 190.

Therefore 190% of the weight limit is 114 pounds.

Answer to Part c:

95% of the weight limit is

= 95 x 60 /100

= 95 x 3/5

= 19 x 3

= 57

Therefore, 95% of the weight limit is 57 pounds.

The factorized form of the quadratic is 2*(x + 2)*(x + 4), and when x = 3m, the walkway area is 52 square meters.

Here we know that the area is given by the expression:

2x^2 + 12x + 16

To factorize this, we need to find the roots of the quadratic equation, these are the solutions of:

2*x^2 + 12x + 16 = 0

The solutions are given by:

x = (-12 ± √(12^2 - 4*2*16))/(2*2)

x =  (-12 ± 4)/4

The two solutions are:

x = (-12 + 4)/4 = -2

x = (-12 - 4)/4 = -4

Then the factored form is:

y = 2x^2 + 12x + 16 = 2*(x^2 + 6x + 8) = 2*(x + 2)*(x + 4)

Now we want to get the area if the walkway if x = 3, the total area of the walkway and the garden will be:

y = 2*(3 + 2)*(3 + 4) = 70

And the garden measures x by 2x, then if x = 3, the area of the garden is:

a = x*2x = 3*(2*3) = 18

Then the area of the walkway alone is:

70 - 18 = 52

The area of the walkway is 52 square meters.

Circles are related to Pythagorean theorem in the sense that the equations are alike and the sides conforms to:

The distance between the two cities is 116.62 units (ignoring curvature)

If the curvature is not ignored then we sort for the angle subtended

The Pythagorean theorem relates the square of hypotenuse, square of the opposite, and the square of the adjacent as follows

hypotenuse^2 = opposite^2 + adjacent^2       equation 1

Representing a circle in a coordinate axis will give it values in coordinate form. Assuming the coordinate of the center is (x1, y1) and a point in the circumference is (x2, y2). The radius of the circle, r is given as

r^2 = (x2 - x1)^2 + (y2 - y1)^2                              equation 2

comparing equation 1 and 2 shows that

radius ≅ hypotenuse,  (x2 - x1)^2 ≅ opposite, and (y2 - y1)^2 ≅ adjacent

say A = (45, -123)

say B = (53.65, -6.7)

Let the distance between the two cities be d

d^2 = (53.65 - 45)^2 + (-6.7 - (-123) )^2

d^2 = 8.65^2 + 116.3^2

d = √13600.5125

d = 116.62 units (ignoring the earth curvature)

if the curvature is not ignored then we look for the angle subtends

$525

Step-by-step explanation:

Ben bought the house for $78,850 so 78,850 divided by 0.15 equals 525. So the answer is $525.

The number of outfits she can buy is 3.

The The first step is to determine the total cost of all the items already bought.

Total cost = cost of new bicycle + (cost of one reflector x number of reflectors) + cost of the gloves

$488.20 + (2 x $11.17) + 19.05

$488.20 + 19.05 + $22.34 = $529.59

Now, determine the amount that is left to buy the outfits :

$660 - $529.59 = $130.41

Here are inequality signs and what they mean:

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

The value of the trigonometric function secθ  is 3/4.

Given the value of the trigonometric function sinθ is 4/5

we know that sinθ = Perpendicular (P)/Hypotenuse(h)

Therefore, sinθ = 4/5;

perpendicular (p) = 4 and

hypotenuse (h) = 5

In trigonometry, the secant function is a periodic function. The ratio of the hypotenuse's length to the base's length in a right-angled triangle is known as the secant function, or sec function. It is also written as sec x = 1 / cos x since it is the reciprocal of the cosine function.

secθ = base(b) / perpendicular(p)

Therefore, Base (b) = √(h² ₋ p²)

= √(5² ₋ 4²)

= √(25 ₋ 16)

= √9

= 3

Now, therefore secθ =  base(b) / perpendicular(p)

= 3/4

Hence we get the value of secθ as 3/4.
