Answer:
460 ft^2 of carpet will be replaced
Step-by-step explanation:
You need to find the area of the room and then take away the area of the six bookcases
<u>Area of the room</u>
20*20=400ft^2
35-20=15ft
(15*20)/2=150ft^2
400+150=550ft^2 total room area
<u>Area of bookcases</u>
2.5*6*6=90ft^2 total bookcase area
<u>room area - bookcase area = carpet area</u>
550-90=460ft^2
Answer:
Step-by-step explanation:
r=5 ×90/100=4.5 in
h=6×90/100=5.4 in
a.
volume of original cylinder=π×5²×6=150 π≈471.24 in³
b.
volume of new cylinder=π×4.5²×5.4=109.35 π in³≈343.53 in ³
c.
decrease in volume=150 π-109.35 π=40.65π
% decrease=(40.65 π)/150 π×100=4065/150=1355/50=27.1 %
Answer:
40.45 cm
Step-by-step explanation:
Length of Lina's green pepper plant = 32.65 cm
It grows 2.6 cm during the months of July, August, and September.
Length at the end of July = 32.65 cm + 2.6 cm = 35.25 cm
Length at the end of August = 35.25 cm + 2.6 cm = 37.85 cm
Length at the end of September = 37.85 cm + 2.6 cm = 40.45 cm
So, its length will become 40.45 cm at the end of September.
The answer to this question is 4x= y-4
A net is a pattern made when the surface of a three-dimensional figure or solid is laid out flat showing each face of the figure. It is then possible to use the net to calculate the surface area of the solid.
