First lets get the formula for a triangular prism

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

First lets plug in our numbers

$v =( \frac{1}{2} \times 7 \times 4)8.5$

It really doesnt matter how you multiply everything, but you end up with 119cubic feet.

Number 35 Plz someone help me in this problem ❤️

Free_Kalibri [48]

Greetings!

This can be solved by creating an algebraic equation:
$8.75(30)+11x=400$

Solve for x.
$262.5+11x=400$
Add -262.5 to both sides.
$(262.5+11x)+(-262.5)=(400)+(-262.5)$
$11x=137.5$
Divide both sides by 11.
$(11x)/11=(137.5)/11$
$x=12.5$

You must work 12.5 hours as landscaper to earn $400 a month.

Hope this helps.
