Answer:
54 students
Step-by-step explanation:
First, change the percent to a decimal.
12% = 0.12
Now, multiply the decimal by the total amount of students to find the amount of students that stay after school.
450 × 0.12 = 54
54 students stay after school for Comedy Club.
Answer:
see explanation
Step-by-step explanation:
The first step is to change the mixed number to an improper fraction
5 
= 
, hence
×
= 
= 
= 30 
The problem says that <span>Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. So, you can calculate the height asked, by following this procedure:
</span>
Tan(α)=Opposite leg/Adjacent leg
α=30°
Opposite leg=x
Adjacent leg=200 feet
When you substitute these values into the formula above (Tan(α)=Opposite leg/Adjacent leg), you have:
Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/200
You must clear "x":
x=200xTan(30°)
Therefore, the value of "x" is:
x=115 feet
<span>
How high above the ground the is the helicopter?
The answer is: 115 feet</span>
F(x) = (1/9 x) - 2
y = (1/9 x) - 2
(1/9 x) = y + 2
x = 9(y + 2) = 9y + 18
f^-1(x) = 9x + 18
Answer:
400
Step-by-step explanation:
There are 100 red gumballs which take up 1/4 of the gumballs. If they are 1/4 of the gumballs that means in total there are 400 because 100 x 4 = 400
