x = 25
Step-by-step explanation:
If the triangles are similar, we know that their corresponding sides are in an equal ratio, so we can set them equal to each other. It's
To set it up, we'll use two fractions. Note that the top numbers, x and 25, are both from the same triangle, and the bottom numbers, 6 and 10, are both from the other triangle. You won't have success if you do this the wrong way.
=
Cross-multiply:
10x = 25*6
10x = 250
<u>x = 25</u>
Answer:
4.2 cubic inches
Step-by-step explanation:
Find the diagram attached
Volume of the rectangular pyramid = BH/3
B is the base area
H is the height of the pyramid
Given
Base area = 3.2in * 1.4in
Base area = 4.48sq. in
Height = 2.8in
Volume of the rectangular pyramid = 4.48*2.8/3
Volume of the rectangular pyramid = 12.544/3
Volume of the rectangular pyramid = 4.2 cubic inches
