Answer:

And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:


And now we can divide both sides by 5 and we got:

So then the number of hours spent to decorate the house are 25
Step-by-step explanation:
Based on the information given we can model this function with this formula:

Where y represent the total cost paid, m the cost per hour representing the slope and x the number of hours worked and finally b the initial cost for the materials. Then our function is given by:

And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:


And now we can divide both sides by 5 and we got:

So then the number of hours spent to decorate the house are 25
Box volume can be computed by getting the base area
multiplied by the total height.
in formula for volume we have,
V = Base Area x H. Given the Volume of 144 cu in and H = 4.5
in. we can solve for Base Area (BA)
Volume (144 cu in) = BA x Height (4.5 in)
BA = 144 cu in/4.5 in
Base Area = 32 square inches
Solution:
As per the problem
A person is born every 5 seconds and a person dies every 12 seconds.
Here the LCD of 5 and 12 is 60.
The number of person born in 60 seconds
The Number of person died in 12 seconds
Hence Population increase in 60 seconds is
Hence time required to increase the population by one 
The answer for this would be
C = 5000 + 200t
8 ounces because 1 quart equals 36 ounces. 36 Divided by her and her 3 friends equals 8 since 36 divided by four equals eight.
