(a) Volume of any Pyramid =   \frac{1}{3} * (Base-Area)*height = \frac{1}{3} *220.22*9 = 660.66 cubic units

(b) Sarah doesn't have to go through all the hard work as the smaller pyramid has a ratio of 2:3 to the bigger pyramid, so we get the equation, to help us solve it.

660.66 = \frac{2}{3} *(Area-of-larger-pyramid)

Hope that helps!

(x-19)/2=(x-7)/1<br><br>step by step please ​
Maksim231197 [3]

Answer:

X=-5

Step-by-step explanation:

Since anything divided by one is still that number, then (x-7)/1 becomes x-7. So our equation now looks like:

(X-19)/2=(x-7).

Multiplying both sides by 2, we get

X-19=2x-14

Adding 19 to both sides:

X=2x+5

Subtract 2x from both sides:

-x=5

Multiplying both sides by -1, we get:

X=-5

I need help plzz<br> x + 3/5 = 2/10
Stels [109]

Step-by-step explanation:

x=2/10 - 3/5

Divide

x + 1/5=3/5

Subtract 1/5 from both sides of the equation

x + 1/5 - 1/5= 3/5 - 1/5

x=2/5
