12

So,
r+ -12+ 12 = 19+ 12
r+ 0 = 31
R=31

Answer:

Step-by-step explanation:

Then the -12 and +12 will cancel out, so you're left with a clean isolated r on the left:

r -12 +12 = 19 + 12

r = 31

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

The "one head and one tail" would be my best guess because you get one of each outcome, whereas the other two outcomes are two of the same outcome.
