earnings = $7 per hour
He needs at least $230 . This means he needs an amount greater than or equals to $230.
let
t = hour many hours he works

-19.8 > 3.6y
-19.8/3.6 > 3.6y/3.6
-5.5 > y
Select 4 from 9, and 3 from 8. Multiply together.
C(9,4)*C(8,3)
=9!/(4!5!) * 8!/(3!5!)
=7056
I’ll help comment the questions and I’ll answer
For a 30-60-90 triangle
if the shorter leg (oposite 30 degrees) is x then the other leg is x√3 and the hyptonuse is 2x
so
hyptonuse=8
8=2x
4=x
longer leg is 4√3, yep
so shorter leg or height will be 4 units
