Answer:
C
Step-by-step explanation:
Answer:
20 ft
Step-by-step explanation:
We know that
Perimeter of rectangle = 2(l + w)
Let the width be w
=> 104 = 2(32 + w)
=> 104/2 = 32 + w
=> 52 = 32 + w
=> 52 - 32 = w
=> 20 = w
Hence z
Width of playground is 20 ft
Step-by-step explanation:
x = -4/5 = -0.8
P(t)=number of sheet of paper after t minutes.
p(t) will have to be equal to 0, wnen the printer use all 100 sheets of paper;
Therefore;
if p(t)=0
Then:
-8t+100=0
We solve this equation.
-8t+100=0
8t=100
t=100/8
t=12.5
Answer: the printer prints 100 sheets of paper in 12.5 minutes.
