y = 12x represents the gallons of paint used in x hours.
Step-by-step explanation:
CJ uses 3 gallons of paint in 15 minutes,
15 minutes = 3 gallons
1 minutes = 
1 hour = 60 minutes
Gallons of paint used in 1 hour;
1 hour = 
CJ uses 12 gallons of paint in 1 hour.
For x hours = 12*x = 12x
Gallons of paints used = y
y = 12x represents the gallons of paint used in x hours.

For this case what we can do is the following rule of three:
24.3 -----> 130%
x ---------> 100%
We clear the value of x:
x = (100/130) * (24.3)
x = 18.7 grams
Answer:
the current mass of the object was:
x = 18.7 grams
For this case we have the following equation:
E = 9m + 8100
Substituting E = 8865 we have:
8865 = 9m + 8100
Clearing m we have:
9m = 8865-8100
m = (8865-8100) / (9)
m = (765) / (9)
m = 85 Kg
Answer:
Gavin's mass is:
m = 85 Kg
Answer:
Option A.
Step-by-step explanation:
In order to write any polynomial in standard form, we need to check the degree of each term, then write each term in order of degree, from highest to lowest, left to right.
The given polynomial is

Here, the combine degree of x and y in each term is 4.
If we arrange the terms according to the degree of x, then

If we arrange the terms according to the degree of y, then

Hence, the correct option is A.
Answer: 0.0026
Step-by-step explanation:
Given: Mean : 
Standard Deviation : 
Sample size : 
Formula to calculate z-score :-

For X=7.6 hours.


Hence, the probability that their mean rebuild time is less than 7.6 hours = 0.0026
