So first we need the formula for a triangular prism

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

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

Answer:
Step-by-step explanation:
Let q represent the number of quarters. Then the number of nickels is 68-q, and the number of cents in the jar is ...
25q +5(68 -q) = 800
20q +340 = 800 . . . . simplify
20q = 460 . . . . . . . . subtract 340
q = 23 . . . . . . . . . . . divide by 20; this is the number of quarters
68-q = 45 . . . . . . . find the number of nickels
The jar contains 23 quarters and 45 nickels.
Hello there! y < -15
To solve, isolate y. To do this, subtract 30 from both sides of the equation.
y + 30-30 < 15-30
y < -15
This is your final answer. The statement is saying that y must be less than -15 when you add 30 to it for your final answer to be less than 15.
I hope this was helpful and have a great rest of your day! :)
