Answer:
180
Step-by-step explanation:
1 foot a minute = 0.0113636364 miles a hour
15840 • 0.0113636364 = 180.000001
So pretty much just round down
Answer:
I dont know it and why did you leave it off the last minute and use photo math
Step-by-step explanation:
Answer: 3/14
Step-by-step explanation:
3 * 2 = 6
4 * 7 = 28
6/28 = 3/14
Answer:
6, 8, 4
Step-by-step explanation:
the answers are as follows
a. 6
b. 8
c. 4
We use the trigonometric function for this case. An escalator is an inclined path. We form a right triangle since we have given the value of the height. The height from the first floor to second floor is called the adjacent while the travelled distance of the people is called the hypothenuse. We use cosine function because we are given in terms of adjacent and hypothenuse. The ratio of cosine function is
cos x = a/h
where x is the angle
Solving for h,
h = a/(cos x) = 21/(cos 30) = 24.25 ft
