As per the direct variation formula, it take  11 hours : 6 minutes : 36 seconds to earn $25,000 for the restaurant.
Direct variation:
Direct Variation is said to be the relationship between two variables in which one is a constant multiple of the other.
Direct variation equation:  y = kx
Given,
A local fast food restaurant takes in $9000 in a 4 hours period. Write a direct variation equation for the relationship income and number of hours. 
Here we need to estimate how many hours it would take the restaurant to earn $25,000.
a) Let us consider income (I) directly varies to number of hours (h) where k is the constant of variation.
I = kh   ⇒  Direct variation equation
Solve for k:
9,000 = (k)(4)
k = 9,000/4
k = 2,250
b) When income (I) = 25,000, find the number of hours:
I = kh
25,000 = (2,250) (h)
h = 25,000/2,250
h = 11.11
It will take approximately 11 hours : 6 minutes : 36 seconds for the restaurant to earn $25,000.

Answer:
This figure is a quadrilateral, and therefore the sum of the interior angles must be 360°.  Adding them up, we get 40° + 128° + x + 82° = 360°, or
168° + 82° + x = 360°, or  250° + x = 360.  Subtracting 250° from both sides results in 110°, which is the measure of x.

Answer:
Hello your question is not well written attached below is the complete question
answer : 
a) smallest value = $0.405 million
    largest value = $22 million
b) smallest value = $0.505 million
    largest value =  $9.332 million
Step-by-step explanation:
A) what are the smallest and largest yearly salary values in the population
smallest value = $0.405 million
largest value = $22 million
b) What are the smallest and largest sample mean in the sampling distribution
Smallest value = $0.505 million
Largest value =  $9.332 million
note : values where gotten using statkey on the dataset NFLcontracts2015 as stated in the attached document ( question )
 
        
             
        
        
        
Answer:
108 pi inches cubed
Step-by-step explanation:
The volume of a cylinder is base area times volume. Since we have our base area of 12 pi, and our height of 9, we have the are as 12* 9 = 108 pi inches cubed. Thus, the answer is D.
