Cody made deposits of $45, $18, and $27 into his checking account. He then wrote checks for $21 and $93. What would the expressi
Olenka [21]

Answer:

-90 - (-144)

Step-by-step explanation:

Here you go!

Since we're depositing, you'll add the three numbers.

45 + 27 + 18 = $90

Cody deposits 90 dollars in total.

If you write checks, the numbers go down. So you'll add them, and then subtract that by the 90 dollars Cody deposits.

You'll end up with:

45 + 27 + 18 - (21 + 93)

This can simplify to..

90 - (21 + 93)

But wait! Let's add what's in the parenthesis!

93 + 21 = 144

90 - 144 = t

t = -54

Solving this equation will give you: -54

But the simple way is -90 - (-144)

So first we need the formula for a triangular prism

v = ( \frac{1}{2} bh)h

Which, since we have all of our number for base, and both heights, we can plug it intk our formula

v =  (\frac{1}{2}  \times 15 \times 8) \times 17

When we calculate it, it comes out to be 1020 cubuc feet.
