Ryans living room is 10 feet wide, 12 feet long, and 10 feet high. If one gallon of paint covers 400 square feet of surface area
Delicious77 [7]
We have to calculate the suface of the four walls and the ceiling.
Surface of the four walls=2(10 ft * 10ft ) + 2(12 ft * 10 ft)=200 ft² + 240 ft²=
=440 ft²
Surface of the ceiling=10 ft * 12 ft=120 ft²

Total surface=440 ft² + 120 ft²=560 ft²

Now, we have to caluclate the number of gallons of paint.

1 gallon------------------------400 ft²
x----------------------------------560 ft²

x=(1 gallon * 560 ft²) / 400 ft²=1.4 gallons.

answer: Ryan need to paint all four walls and the ceiling 1.4 gallons.

A small grocery store offers two different brands of milk.
m_a_m_a [10]

Answer:

the total cost of milk for Brand B will pass through the points (0,1.50) and (0.5,4.50).

Step-by-step explanation:

Brand A 2% milk costs $3.50 a gallon. If 0 gallons of milk are purchased, the cost is $0. If 1 gallon of milk is purchased, the cost is $3.50. So, the ray representing the total cost of milk for Brand A will pass through the points (0,0) and (1,3.50).

Brand B whole organic milk costs $3.00 for a half-gallon, plus a one-time deposit of $1.50 for the glass jug. At 0 gallons, the cost is $1.50 for the deposit. At 0.5 gallons, the cost is $3.00 + $1.50, or $4.50. So, the ray representing the total cost of milk for Brand B will pass through the points (0,1.50) and (0.5,4.50).

Since Brand A goes through the origin, Brand A is proportional. The correct graph is shown below.
