Answer:
The answer to your question is:
side 1 = 22.5 cm
side 2 = 30 cm
side 3 = 37.5 cm
Step-by-step explanation:
ratio = 3:4:5
Perimeter = 90 cm
First we get the sum of the numbers of the proportions
3 + 4 + 5 = 12
now divide the perimeter by the number of parts (12)
90 / 12 = 7.5
Side 1 = 3(7.5) = 22.5 cm
Side 2 = 4(7.5) = 30 cm
Side 3 = 5(7.5) = 37.5 cm
Perimeter = 22.5 + 30 + 37.5 = 90 cm

Step-by-step explanation:
Answer: 32 cups of milk
Step-by-step explanation:
The first thing to do is to convert the gallons of milk to milkshakes so that you are able to convert easier to cups.
There are 128 ounces in 1 gallon and Monica has 2 gallons. The amount of milk Monica has in ounces is:
= 128 * 2
= 256 ounces
Each cup is capable of holding 8 ounces and there are 256 ounces available so the number of cups of milk is:
= 256 / 8
= 32 cups of milk
Step-by-step explanation:
x^2+(x+9)^2=90
x^2+(x+9)^2-90=0
x^2+x^2+9^2+2*x*9-90=0
x^2+x^2+81+18x-90=0
2x^2+18x-9=0
Quantity of animal feed in the barn initially = 96 kg
Fraction of animal feed that was wasted = 1/10 of initial quantity
Quantity of animal feed wasted= (1/10) *96 = 9.6 kg
Quantity of animal feed left = Quantity of animal feed initially - Quantity of animal feed wasted
Quantity of animal feed left = 96-9.6= 86.4 kg
Answer: 86.4 kg of animal feed was left in the barn.
