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
Answer:
See below
Step-by-step explanation:
The pie chart gives the percentage of the $ 4675 that goes to each expense
Housing 16 % .16* 4675 = $ 748
Food 16% .16 * 4675 = $748
Childcare 18% .18 * 4675 = $ 841.50
Trnsport 13% .13 * 4675 = $ 607.75
etc I think you can do the others---- right ?
Answer:
(4-2)x12=24
(7-3)x12=48
24+24+48+48=144
Step-by-step explanation:
That would be 1.175 Answer
Answer:
c
Step-by-step explanation:
the probability isn't unavailable so it's not A. 0
and it isn't less than 0 because it is still "may occur"
and it is not one because it is still "unlikely"
so its C. close to 0
