Answer: C and E
Step-by-step explanation:
The plane starts at 32,460 feet.
It then ascends 1645 feet. Ascending means it's going up higher. So we add.
32,460 + 1645 = 34,105 (C)
From here (34,105 feet) the plane descends by 3/5 of it's height. Descending means it's lowering. So we subtract.
But first we have to figure out how much we are subtracting.
3/5 is equal to .6
Multiply to find 3/5 of current height.
34,105 × .6 = 20,463
So the plane descends by 20,463 feet.
34,105 - 20,463 = 13,642 feet (E)
It has four intersecting line segments lol
Answer:
The answer is 792.
Step-by-step explanation:
I got the answer by first imagining how the 3d shape looks ike. Since one of the sqaure base length is 11 I found the base surface area by doing 11 times 11.My answer was 132. The since one of the slant length of the pyramid's triangle is 15, I did 11 times 15, my answer was 165. There are four triangles in the pyramid so I did 165 times 4, my answer was 660.
All the triangle surface area is 660 plus the sqaure surface are which is 132, that gave me my answer 792.
