Answer: 36h, 60+16.2h, and $92.40.
Step-by-step explanation:
n(h)=36h because there are 3 dozen cupcakes made per hour, to get C(h) you just plug in 36h in place of n and simplify, and then for the final answer 2 is plugged into the equation from the second answer.
A. Given (This is part of the original problem)
b. Supplementary angles form 180 degrees (The definition of supplementary angles is that two or more angles have a sum of 180 degrees. DC is a straight line and has a measure of 180 degrees)
c. Substitution (Given the two previous statements, they are each equal to 180 degrees. Since 180=180 then you can substitute the angles in the equation.)
d. Subtraction (m<2 is being subtracted)
e. Subtraction postulate (Since the same quantity was being subtracted from each side of the equation, they are still equal)
The first answer is correct, if you go back by 5% each year you will see that.
The solution to the problem is as follows:
<span>We use proportion :
Let the height of building = x ft.
We get x/21 = 15/6
x = 15*21 /6
x = 52.5 ft.
height of bldg = 52.5 ft

So do (21/2+49/4)-3/2=You get 21 1/4 miles
Since 21 1/4 is close to 21 1/2, this answer is reasonable. So A is the answer
