Answer: 28.8 ounces of red paint
Step-by-step explanation:
The total amount of paint created the first time Mango mixed colors was:
= 24 + 16
= 40 ounces of purple color
For 40 ounces of purple, 16 ounces of red was needed. Proportion is therefore:
= 16/40
If one wants 72 ounces of purple therefore:
= Proportion of red used * 72 ounces
= 16/40 * 72
= 28.8 ounces of red paint
You have to multiply the coefficient and add the exponents of the variables
He traveled 2080 miles after 4 hours. He covered 3640 miles in 7 hours with a constant speed, so we can calculate the speed: 3640/7=520 miles/hour. After 4 hours, he traveled 520*4=2080 miles.
The slope of the original line is 1 so the perpendicular slop is -1
