Answer:
1.05 m
Step-by-step explanation:
The area of a rectangle is length x width
The area is given as 18,900 cm2 and the width is 1.8 m
These need to be in the same unit, either cm or m
1 m = 100 cm
change the 1.8 m width to cm by multiplying by 100
1.8 x 100 = 180 cm
plug in 180 for the width
again, area = L x W
so 18,900 = L x180
L = 105 cm
The question asked for the length in meters so convert back
105 cm ÷ 100 = 1.05 meters
Answer: 1.05 meters
Time taken to ride 1 mile=7 min.
So time taken to ride 4 mile=4×7=28min.
Answer:
0.0869
Step-by-step explanation:
The arc electronic company had an income of 90 million dollars last year.
Mean(μ) = 75 million dollars
Standard deviation (σ) = 11 million dollars
Probability that the randomly selected will earn more than arc did last year = Pr(x>90)
Using normal distribution,
Z = (x - μ) / σ
Z = (90 - 75) / 11
Z = 15/11
Z = 1.36
From the normal distribution table, 1.36 = 0.4131
Φ(z) = 0.4131
Recall that when Z is positive, Pr(x>a) = 0.5 - Φ(z)
= 0.5 - 0.4131
= 0.0869
Answer:54 1/72
Step-by-step explanation: 1st you multiply the whole numbers. 2nd multiply denominators (8•9) =72 3rd put into fraction form. So your answer is 54 1/72. Does this make sense?
