Answer:
146
Step-by-step explanation:
Get a percent calculator, Then, you put 51.2% of 285 and you actually get 145.96 but the rounded of what you need is 146
Answer:
A = 92y + 81
Step-by-step explanation:
Because A = number of attendees and if it adds 92 each year, you times the number of years by 92 and add 81 for the ones that were already there
3/4 of 3600..." of " means multiply
3/4 * 3600 =
10800/4 =
2700 <==
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
