Ade has two similar scale models of the same pyramid. The first model has aheight of 5 inches and a surface area of 80.9 square inches. The linear dimensions
of the second model are each increased by a common factor so that the height of
the second model is 15 inches. To the nearest tenth of a square inch, what is the
surface area of the second model?

Please help!

Answers

Answer: 242.7 square inches

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

The first model has a height of 5 inches and a surface area of 80.9 square inches:

The proportion is : height/ surface area= 5 in / 80.9 in2

For a height of 15 inches

15 in/ x in2

So:

5/80.9 = 15/x

x= 15/ (5/80.9 )

x= 242.7 square inches

Why is the sun right next to the Earth

Answers

no not really because the sun not too close to the sun and not too from the sun so the earth is a goldilocks planet.

The sun is not right next to the earth. It is closer than Pluto though. I don't think anybody knows the answer to this though. God made everything, and he made the sun, earth and moon, along with the other planets and stars. God probably put the sun next to the earth so he could keep all living things on earth warm, but not on fire. Hope this was correct and helped!

Please help with this problem . Break it down for me 15-1/6n=1/6n-1

Answers

15-1/6n=1/6n-1
First, lets multiply both sides by 6 so that n is a whole number:
90-n=n-6
now you group like terms on each side, to do this you add n to each side and add 6 as well so it becomes:
96=2n
Now divide both sides by 2 so you have 'n' on one side and it is:
48=n

Hope this helps :)

Math:

Step 1: Simplify both sides of the equation. Simply steps provided.

15−1/6n=1/6n−1

15+−1/6n=1/6n+−1

−1/6n+15=1/6n−1

Step 2: Subtract 1/6n from both sides.

−1/6n+15−1/6n=1/6n−1−1/6n

−1/3n+15=−1

Step 3: Subtract 15 from both sides.

-1/3n = -16

Step 4: Multiply both sides by -3 -1/3 by 16.

Your answer is:
n = 48
