Part A
The table does represent y as a function of x because each input (values of x) related to exactly one output. Refer to the diagram below.
Part B
We have
f(x) = 925x + 1000
f(24) = 925 (24) + 1000
f(24) = 23200
f(24) represent the value of renting for 24 months
 
        
        
        
Answer:
240 minutes or 4 hours
Step-by-step explanation:
So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes. 
If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.
Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.
So you have 45/80 and 45/120.
Now add both fractions by finding the lowest common denominator which is 240.
135/240 + 90/240 = 225/240
So Mack did the remaining 15/240.
Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.
Then multiply
15 x 16 = 240
so it would take him 240 minutes or 2 hours.
 
        
             
        
        
        
Answer:
12
Step-by-step explanation:
The range of a data set is just the difference between the largest and smallest values. 
So, let's find the smallest value: it's 39. The largest value is 51.
Their difference is:
51 - 39 = 12
Thus, the answer is 12.

Answer:
Step-by-step explanation:
Volume of a cube:
V = a3
Surface area of a cube:
the area of each face (a x a) times 6 faces
S = 6a2
Face diagonal of a cube:
By the pythagorean theorem we know that
f2 = a2 + a2
Then f2 = 2a2
solving for f we get
f = a√2
Diagonal of the solid cube:
Again, by the pythagorean theorem we know that
d2 = a2 + f2
substituting f into this equation we get
d2 = a2 + (a√2)2 = a2 + 2a2 = 3a2
solving for d we get
d = a√3
