What is the equation of line l?

inessss [21]

Y=-3/2L -2. At the Y axis, line L is at -2, so we add that as B or the Y intercept. We can see that the graph goes 2 over to the right and down three, which makes the slope negative and 3/2 (rise/run)

Suppose the height of the pyramid is 20 yards. What is the pyramid's volume?

DedPeter [7]

Answer : The correct option is, (B) 1500 cubic yards.

Step-by-step explanation :

Formula used to calculate the volume of square pyramid is:

$V=\frac{a^2\times h}{3}$

where,

V = volume of pyramid

a = base edge of pyramid

h = height of pyramid

Given:

Base edge of pyramid = 15 yards

Height of pyramid = 20 yards

Now putting all the given values in the above formula, we get:

$V=\frac{a^2\times h}{3}$

$V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}$

$V=1500\text{ yards}^3$

Therefore, the volume of pyramid is 1500 cubic yards.
