V = 120 in^3

Here is why:

The volume formula for a pyramid is:

$V=\frac{1}{3}Bh$

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.

The area formula for a triangle is:

$A=\frac{1}{2}bh$

Plug in the numbers.

$A=\frac{1}{2}*9*10$

A = 45

Now we have found the area of B, we can plug it into the volume formula for the pyramid.

$V=\frac{1}{3}*45*8$

V = 120 in^3

What are the coordinates of point S? On a coordinate plane, point S is 0.75 units to the left and 0.5 units up. (Negative three-

ZanzabumX [31]

Answer:

The coordinates of S is $( \frac{-3}{4}, \frac{1}{2})$

Step-by-step explanation:

We are supposed to find the coordinates of point S

Point S is 0.75 units to the left

So, x coordinate of point S = -0.75 = $\frac{-3}{4}$

Now we are given that point S is 0.5 units up.

So, y coordinate of point S = 0.5 = $\frac{1}{2}$

So, The coordinates of S is $( \frac{-3}{4}, \frac{1}{2})$

So, Option A is true .
