Jude says that the volume of a square pyramid with base edges of 7 in and a height of 7 in is equal to the volume of a cylinder with a radius of 7 in and a height of 7 in. jude rounded all answers to the nearest whole number. examine jude's calculations. is he correct?

volume of square pyramid volume of cylinder
v = b(h) v = r2h
v = 49(7) v = (72)(7)
v = 343 in2 v = 343 in2
yes, his calculations are correct and the volumes for figures are equal.
no, he made a mistake in solving for the volume of the square pyramid.
yes, but he made a mistake in solving for the volume of the cylinder.
no, he made a mistake in solving for the volume of both figures.

step-by-step explanation:

answer: 48

just remember to use pemdas:

parentheses

addition

subtraction

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
