The hypotenuse of a right triangle is 37 mm. One leg of the right triangle is 12 mm. What is the length of the other leg?

rjkz [21]

Use the pythagorean theorem:
$a^2+b^2=c^2$
$12^2+b^2=37^2$
$144+b^2=1369$
$b^2=1225$
$\sqrt{b^2} = \sqrt{1225}$
$b=35$
Your answer is 35mm.

r(b) = 12b

c(b) = 4 + 3.3b

I think profit is revenue minus the cost, so p(b) = r(b) - c(b)

= 12b - (4 + 3.3b)

12b - 4 - 3.3b //Combine like terms

8.7b - 4

Answer: D

//Hope it helps and it's right.

Goryan [66]

All we have to do for this is multiply 5.4 by 1000, since the ration already has liters as 1.
5.4 × 1000 = 5,400
There are 5,400 milliliters of juice in the jar.
