20 ft in 1 sec
60 x 20ft in 1 min
60 x 60 x 20ft in 1 hr
72000 ft in 1 hr
5280ft = 1 mile
speed = 72000/5280 mph
Answer:
The correct answer is C.
Step-by-step explanation:
percentile is represented as the value of probability in the norma distribution.
We look for a z-value with a left-tail of 0.67.
z=0.44
where,
M: mean
SD: standar deviation
x=z×SD+M=0.44×0.3+M=M+0.132
The diameter of an orange at the 67^th percentile is 0.132 inch above the mean.

Answer:12cm
Step-by-step explanation:
The ratio are:
4:6:9
Perimeter=57cm
Let a be the unknown value.
The triangle has three sides: 4a, 6a, 9a
Perimeter=The sum of three sides
57=4a + 6a +9a
57=19a
Divide both side by 19
a=57/19
a=3
Therefore
4a:6a:9a
4×3:6×3:9×3
12:18:27
So the shortest side is 12cm
