Rectangle $ABCD$ is the base of pyramid $PABCD$. If $AB = 8$, $BC = 4$, $\overline{PA}\perp \overline{AD}$, $\overline{PA}\perp
11Alexandr11 [23.1K]

Answer:

<h2>181.33</h2>

Step-by-step explanation:

Since the base of the pyramid PABCD is a rectangle, the shape in question is a rectangular based pyramid. Volume of a rectangular based pyramid is expressed as V = 1/3 * Base Area * Height of the pyramid.

Given a rectangle ABCD with AB = 8 and BC = 4, the area of the rectangle will be equivalent to the base area of the pyramid.

Base Area = Length * Breadth

Base Area = AB * BC

Base Area = 8*4 = 32

If \overline{PA}\perp \overline{AD}\ and \ \overline{PA}\perp \overline{AB}, and PB = 17, then the height of the pyramid is PB = 17.

Volume of the pyramid = 1/3 * 32 * 17

Volume of the pyramid = 1/3 * 544

Volume of the rectangular based pyramid = 181.33

The part (aka "is") = 8 and the percent is 42, what is the whole (aka
marysya [2.9K]

Answer:

33

Step-by-step explanation:

If you simplify what the question is saying, it's basically..

8 is 24% of <u>what number?</u>

To find out, you can simply set up an equation.

((24% = 0.24 as a decimal (move the decimal point two times to the left))

8 = 0.24 x N (N is just the 'whole')

To solve, you just need to divide 8 ÷ 0.24. So, N = 33.333 repeating.

The question says to round to the nearest whole number, so the answer would just be 33.

Which correctly describes how the graph of the inequality −4y − x ≥ 7 is shaded?
harkovskaia [24]

Answer: Below the solid line

Step-by-step explanation:

-4y - x ≥ 7

add x to both sides

-4y ≥ x + 7

divide by -4 on both sides

y ≤ -1/4x - 7/4 = (1.75)

Take the origin (0,0) and substitute it for the variables

y(0) ≤ -1/4(0) - 7/4

0 ≤ -7/4 = (1.75)

This statement is false, so you would shade on a graph, below the solid line, since this is where the origin would not be.

The line would be solid because the < is underlined.
