Answer:
<u>6.2 = Altitude</u>
Step-by-step explanation:
Hypotenuse = 8
Base = 5
Altitude = x
Hypotenuse² = Base² + Altitude²
8² = 5² + Altitude²
64 = 25 + Altitude²
64 - 25 = Altitude²
39 = Altitude²
√39 = Altitude
<u>6.2 = Altitude</u>
Answer:
80
Step-by-step explanation:
So, let's say the total number of pizzas is x
If 15% of x, the total, is 12, then x * 0.15 must = 12
Use this to make an equation
12 = 0.15x
Divide both sides by 0.15 to get x on its own
12 / 0.15 = x0.15 / 0.15
80 = x
80 pizzas were sold
