Mademuasel [1]

Answer:

150 in^2

Step-by-step explanation:

The surface area, in general, is A = 6s^2, where s is the length of one side of the cube.

If the edge length is 5 in, then the surface area of the cube is

A = 6(5 in)^2 = 6(25 in^2) = 150 in^2

The equations that could represent the quantities and constraints in this  situation are:

m = 12(15) ⇒ answer a

4n = c ⇒ answer c

b = 2(3) + 3(4.50) ⇒ answer e

Step-by-step explanation:

Jada plans to serve milk and healthy cookies for a book club meeting

  • She is preparing  12 ounces of milk and 4 cookies per person
  • There are 15 people in  the club
  • A package of cookies contains 24 cookies and costs $4.50
  • A 1-gallon jug of  milk contains 128 ounces and costs $3

n represents number of people in the club,  

m represents the ounces of milk

c represents the number of cookies

b represents Jada's budget in dollars

∵ m represents the ounces of milk

∵ She is preparing  12 ounces of milk

∵ There are 15 person in the club

∴ m = 12(15)

∵ She is preparing 4 cookies per person

∵ c represents the number of cookies

∵ n represents the number of people in the club

∴ 4n = c

∵ A package of cookies contains 24 cookies

∵ She needs = 15 × 4 = 60 cookies

∵ 60 ÷ 24 = 2.5

∴ She needs to buy 3 packages of cookies

∵ She needs = 15 × 12 = 180 ounces of milk

∵ A 1-gallon jug of  milk contains 128 ounces

∵ 180 ÷ 128 = 1.406

∴ She needs to buy 2 A 1-gallon jug of milk

∵ The cost of each jug of milk is $3

∵ The cost of each package of cookies is $4.50

∵ b represents Jada's budget in dollars

∴ b = 2(3) + 3(4.50)

The equations that could represent the quantities and constraints in this  situation are:

m = 12(15) ⇒ answer a

4n = c ⇒ answer c

b = 2(3) + 3(4.50) ⇒ answer e
