Mahmoud is doing some plumbing repairs. He runs a pipe through a rectangular wall making a 70 angle. Afterward, he puts the pipe
through another wall which is parallel to the first. Mahmoud can therefore assure the homeowner that the pipe forms a ____ angle
with the second piece of wall.

Answers

Answer:

The correct option is;

(D) 70°

Step-by-step explanation:

By running the pipe through the first wall, to the second wall which is perpendicular to the first, we have;

The angle the pipe makes = 70°

Therefore, due to the spring back effect the formed by the pipe when bent 90° is 70°

Therefore, By running the pipe from the second wall, to the third wall which is parallel to the first, and perpendicular to the second wall, the angle the pipe forms is also a 70° angle

Mahmoud can therefore assure the home owner that the pipe forms a 70° angle with the second piece of the wall.

find the slope of the following ^ :))
|

Answers

Answer:

m [slope] = 0

Step-by-step explanation:

When the slope is 0, x cancels out so the y value will remain the same.

There are several methods to finding slope but the easiest way to do this is by dividing the second y value - first y value by the second x value - first x value.

m = ∆y/∆x = y2-y1/x2-x1

You y2 and x2 are interchangable with y and x, because y1, and x1 are part of the starting coordinate,.

The reason you subtract the second

value from the first is because in a directly proportional relationship, y increases as x increases so the next x values will have a greater y value, this is a measure of steepness.

So the slope is:

-1 - -1 / 3 - -2 = -1 + 1 / 3 + 2 = 0 / 5 = 0.

A video screen is 16 in. by 12 in. tall. What is the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall?

Answers

Answer:

16 inches, and 10 inches tall, aka Answer D.

So because, they are asking the largest image for the photograph,

so 8 * 2 = 16

and 10 * 2 = 20 but 20 can't go into 12.

Step-by-step explanation:

I think this is right sry if its not

The width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall is 8 in option (B) 8 in is correct.

What is a scale factor?

The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

We have:

A video screen is 16 in. by 12 in. tall.

To find the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall, we can use the scale factor:

Applying the similarity law:

6/12 = 4/x

1/2 = 4/x

x = 4×2

x = 8 in

Thus, the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall is 8 in option (B) 8 in is correct.

Hint: Use an exponential function with base e.
Your answer is P(t)=

(b) Use the function from part (a) to estimate the fox population in the year 2008.

Answers

Answer:

The answer is C!

Step-by-step explanation:

I don't have an explanation, it just came to me, sorry..Hope this helps though!

Answer:

7,854 cm

Step-by-step explanation:

We know that Area of the circle is given by:-

Area = \pi r^2πr2

, where r is the radius of the circle.

Given, A circle has a radius of 50 cm.

i.e. r= 50 cm

Then the circle would be Area = \pi(50)^2=(3.14)(2500)=7853.98163397\approx78547\ cm^2π(50)

=(3.14)(2500)=7853.98163397≈78547 cm

Thus, the area of the circle is approximately 7,854\ cm^27,854 cm

The value of y varies directly with x. If x = 4, then y = 36. Find the value of x when y = 144.

Answers

Answer:

16

Step-by-step explanation:

Direct variation formula: y = kx

Given

x = 4, y = 36

Finding the coefficient k:

36 = 4kk = 36/4k = 9

So the function is

y = 9x

Solving for x, when y = 144

144 = 9xx = 144/9x = 16
