Answer:
16.5
Step-by-step explanation:
5 ft every 2 seconds= 2.5 ft per second 3 seconds= 7.5ft
24-7.5=16.5
Answer:
the length and width . Round to the nearest tenth are 8.8 inches and 3.8 inches respectively.
Step-by-step explanation:
The area A of a rectangle is the product of the length L and width W. This may be expressed mathematically as
A = L * W
As such, given that the length is 5 inches more than the width,
L = W + 5
33 = W(W + 5)
W² + 5W - 33 = 0
Using the formula method which states that
s = -b±√(b²-4ac)/2a
W = -5 ± √5² - 4(1)(-33)/2
= -5 ± 12.53/2
= 7.53/2 (since length cannot be negative)
= 3.755 inches
L = 3.755 + 5
= 8.755 inches
Answer:
<u>Trapezoid area:</u>
- A = 1/2(a + b)h, where a, b - bases , h - height
<h3>17. a)</h3>
- a = RS = 4 units
- b = AT = 8 units
- h = 8 units, the distance between RS and AT
A = 1/2(4 + 8)*8 = 48 units²
<h3>17. b)</h3>
- a = SK = 4 units
- b = OC = 10 units
- h = SO = 6 units
A = 1/2(4 + 10)*6 = 42 units²
<h3>18. a)</h3>
- a = ME = 6 units
- b = AZ = 10 units
- h = MA = 8 units
A = 1/2(6 + 10)*8 = 64 units²
