Answer:
61.5 ft²
Step-by-step explanation:
To find the area of the floor that is not covered by the rug, you need to find the total area of the room and subtract the area of the rug. The formula for the area of a rectangle is:
A = length x width
(10 x 12) - (6.5 x 9) = 120 - 58.5 = 61.5 ft²
12 and 1/8, I just simplified 2/16 to 1/8
Mean of the 5 is the average
lets solve for what score gets 80
and lets say last score is x
so
(sum of scores)/4=80
(62+75+90+x)/4=80
(227+x)/4=80
times 4 both sides
227+x=320
minus 227 from both sides
x=93
yo need a 93
good luck
Answer:
2(x + 10)
Step-by-step explanation:
The perimeter is all the sides added together so you times the length by 2, (8 × 2 = 16). Then the width by 2 ( 2 × (x+2) = 2x + 4) add them together
16 + 2x + 4
2x + 20
take out the highest common factor of 2
2(x + 10)
