I'm sorry cuz I don't know how to explain it
Answer:
25% increase
Step-by-step explanation:
You multiply the original number (0.25) by 100.
% increase = Increase ÷ Original Number × 100. If the answer is a negative number, that means the percentage change is a decrease.
We have the base measurement for the triangles composing the sides. We need their altitude.
Imagine a right triangle with these sides:
(1) from the apex of the pyramid to the point on the base directly underneath it (471 ft);
(2) from the middle of base edge to the point underneath the apex (half of 708 ft = 354 ft);
(3) the hypotenuse, the altitude of a triangular side.
Using the Pythagorean Theorem, we find the hypotenuse to be
√(471^2 + 354^2) = about 589.2 feet
Now we add up the four triangles' areas. Each is base * altitude / 2, so:
4 x 708 x 589.2 / 2
= 2 x 708 x 589.2
= 834,307.2 square feet, the lateral area.
The y value should be -128
Answer:
Hi I think the answer would be D
