Vida painted 6 rooms in 24 hours. Each room had 400 square feet of wall space that was painted. At what rate did Vida paint, in square feet per hour?
A.
100 square feet per hour
B.
16.67 square feet per hour
C.
33.33 square feet per hour
D.
200 square feet per hour

A) 100 square feet per hour.

Step-by-step explanation:

Each room has 400 square feet of wall space. There are 6 rooms in all. Multiply 400 with 6:

400 x 6 = 2400.

Vida paints painted these 2400 square feet in 24 hours. To solve for the amount of square feet per hour, simplify divide square feet with hours:

2400/24 = 100

100 square feet per hour is your answer, or A).

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
