b= 16 mm

Step-by-step explanation:

Pythagorean theorem is a^2 + b^2= c^2, so-

12^2 +b^2= 20^2

144+b^2=400

b^2=400-144

b^2= 256

b= 16

how to find volume of a pool?? what's the formula... I'm in 7th grade and I need help finding the volume of a pool I just need a
gogolik [260]
Let's assume the pool is a rectangular block

If you know the length width and depth (or height) of the pool, then you can find the volume.

For example
length = 30 feet
width = 10 feet
depth = 8 feet
volume = length*width*depth = 30*10*8 = 300*8 = 2400 cubic feet
This is assuming that the depth stays the same throughout the pool. Though some pools (or most?) have the depth gradually get deeper as you move toward the deep-end. To keep things simple however, the assumption is that the bottom is completely flat and it doesn't gradually get deeper.

Karla had $138.72 in her checking account. She wrote checks for $45.23 and $18. Then she made a deposit for 75.85 into her accou
vampirchik [111]

Answer:

$151.34

Step-by-step explanation:

First, Karla starts with $138.72.

Then Karla writes checks for $45.23 and $18.00. This means the money will be withdrawn, so let's subtract these from the total.

$138.72 - $45.23 - $18.00 = $75.49

Now, Karla has $75.49 in her account.

However, a $75.85 deposit is made to her account. So let's add this back to the total.

$75.49 + $75.85 = $151.34

So after all the transactions, Karla has $151.34 in her checking account.
