Answer:

<h2>823.7 m²</h2>

Step-by-step explanation:

If a figure A and a figure B are similar, then

$\dfrac{area_A}{area_B}=k^2$ (*)

<em>k</em><em> - similarity scale</em>

<em />

Calculate the similarity scale:

$k=\dfrac{6}{5}$

We have the surface area of the smaller prism 572 m².

Substitute to the formula (*):

$\dfrac{x}{572}=\left(\dfrac{6}{5}\right)^2\\\\\dfrac{x}{572}=\dfrac{36}{25}\qquad\text{cross multiply}\\\\25x=(36)(572)\\\\25x=20,592\qquad\text{divide both sides by 25}\\\\x=823.68\approx823.7\ m^2$

A square with a perimeter of 14 in. is reduced to a square with a perimeter of 7 in. What is the scale factor of this reduction?

DiKsa [7]

Answer:

So scale factor, I'm either thinking multiplication or division, so here goes:

Step-by-step explanation:

So either division or multiplication is my guess.

We all know 7x2=14, so 14 divided by 7 is 2.

Now let's start a little easy for multiplication; 10x7, easy, 70.

7x4, easy, 28. 70+28= 98 now. So basically 14x7 is 98.

I remember the phrase scale factor from 7th grade.

So try to put the answer that is multiplied (98).

And if that doesn't work, try the divided version (2), vice versa.

Please correct me if I'm wrong, I took time out of my lunch break to write this lol.

Bye!
