Area of a triangle = \frac{1}{2} · base x height
                     180 = \frac{1}{2} · base x 40
                     180 = 20 · base
                        9  = base

Pythagorean Theorem:
base² + height² = hypotenuse²
  9²     +    40²    = hypotenuse²
 81     +   1600   = hypotenuse²
      1681            = hypotenuse²
     √1681           = √hypotenuse²
         41            = hypotenuse

Answer: the length of the hypotenuse is 41 m

John is going camping, and he needs to buy a tent. The outdoor store has one that cost $90, but it's on sale for 25% off. What i
pochemuha

Answer:

A

Step-by-step explanation:

<em>Okay so, im not the best at explaining, but so we have a percentage. its 25%. you want to take the 25% and put it over 100 because a percentage is a number or ratio expressed as a fraction of 100. so it will be written as 25%/100</em>

<em />

<em>divide 25 by 100 and you get 0.25, correct? so that's one step further towards the answer.</em>

<em>then we write x/90 because we don't know (well we do) what we're gonna put. but, we're gonna multiply 0.25 by 90 and we get 22.5, which is equivalent to </em><em>22.50</em><em>.</em>
