Answer:
Length: 124.7875 cm
Width: 7.2125 cm
Step-by-step explanation:
The perimeter of this area can be calculated as:
P = 2L + 2W
Where P is the perimeter, L is the length and W is the width
If the perimeter is 264 centimeters, we have that:
2L + 2W = 264
L + W = 132
The area can be calculated as:
A = L*W
Where A is the area.
If the area is 900 cm2, we have that:
L*W = 900
From the first equation, we have that L = 132 - W
Using this value in the area equation, we have:
(132-W)*W = 900
132W - W2 = 900
W2 - 132W + 900 = 0
delta = b2 - 4ac = 17424 - 3600 = 13824
sqrt(delta) = 117.575
W1 = (132 + 117.575) / 2 = 124.7875 cm
W2 = (132 - 117.575) / 2 = 7.2125 cm
Using the smaller value for W, the length will be:
L + 7.2125 = 132
L = 124.7875 cm

25. time = distance/speed

It took about 432 milliseconds for the ball to travel to the batter.
26. 15 cans at Save Rite will cost 5 times the amount for 3 cans, so will be
... 5×$5.25 = $26.25
15 cans at Spend Less will cost 3 times the amount for 5 cans, so will be
... 3×$7.50 = $22.50
Maria paid $22.50 at Spend Less.
27. Simple interest is computed using
I = Prt . . . . where P is the principal, r is the annual rate, and t is the number of years.
Filling in the numbers gives the interest charge.
I = $8000×0.065×4 = $2080
Malik pays back the principal plus interest, so pays $8000 +2080 = $10,080.
