The surface area of a triangle pyramid is 1,936mm2. If the dimensions are multiplied by 1/4 what will be the new surface area?

Mumz [18]

Answer:

The new surface area will be $121\ mm^{2}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

In this problem

The scale factor is $\frac{1}{4}$

Multiply the scale factor squared by the original surface area to obtain the new surface area

$(\frac{1}{4})^{2}*1,936=121\ mm^{2}$

H. 2x – 7 = 3 squared

Lubov Fominskaja [6]

Answer:

h. x=8

Step-by-step explanation:

$2x-7=3^2$

$2x=16$

3) Divide both sides by 2

$\frac{2x}{2} =\frac{16}{2}$
