Discuss the difference between fixed expenses and variable expenses as they relate to a budget
Answer:
Fixed expences are expences that don't change month-to-month, whereas variable expences are things that are needing to budgeted for every month, but may vary a bit and are therefor usually estimated on a budget.
Step-by-step explanation:
For example, rent would be a fixed expense because you know it will be X amount due on the same day every month. Food, on the other hand, would be a variable expense because it likely won't be the same amount month-to-month.
Answer:
Fixed expenses are expenses that stay the same for a person or a business. An example of a fixed expense is rent/mortgage. This expense doesn't change if you are only using the building for 2 weeks or the entire month, it's a set rate. A variable expense is an expense that changes like an electric bill, it varies based on the month and usage. When you budget, you can easily budget for your fixed expenses but you need to allow some room in your budget for expenses that change.

One jug of powdered plant food treats an area of 140 square feet of flowers. How many jugs would be needed to treat an area of 175 square feet?
Use a graph plz!
Answer:
Step-by-step explanation:
Let [tex]n[/tex] and [tex]A[/tex] the number of jugs and the area of flowers, measured in jugs and square feet. We assume that exists a direct relationship between both variables. That is:
[tex]A \propto n[/tex]
[tex]A = k\cdot n[/tex] (1)
Where [tex]k[/tex] is the proportionality constant, measured in square feet per jug.
If we know that [tex]n = 1\,jug[/tex] and [tex]A = 140\,ft^{2}[/tex], then the proportionality constant is:
[tex]k = \frac{A}{n}[/tex]
[tex]k = 140\,\frac{ft^{2}}{jug}[/tex]
Then, the relationship between both variables is represented by:
[tex]A = 140\cdot n[/tex]
If we know that [tex]A = 175\,ft^{2}[/tex], then the minimum number of jugs needed to treat the area is:
[tex]n = \frac{175\,ft^{2}}{140\,\frac{ft^{2}}{jug} }[/tex]
[tex]n = 1.25\,jugs[/tex]
Since jugs represents a discrete set, then we round this number up to the next integer. In other words, we find that 2 jugs are needed to treat an area of 175 square feet.
Lastly, we present a graph to estimate the minimum value of jugs:

5. Two sides of a right triangle are 8 inches and 12 inches. What is the length of the Hypotenuse
Answer:
19.7ft
Step-by-step explanation:
o^2+a^2=h^2
\dpi{100} h^{2}=(10ft)^{2} +(17ft)^{2}
h^2=100ft^2+289ft^2
h=389ft^2−−−−−√
→19.7ft
Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
where a and b are the legs of the triangle and c is the hypotenuse
so 8^2 + 12^2 = c^2
64 + 144 = c^2
208 = c^2
take the square root of both sides
c = 14.422
PROVE ALGEBRAICALLY THAT 0.5 = 5/9
Answer:
See Below.
Step-by-step explanation:
Let:
[tex]0.\overline{5}=n[/tex]
If we multiply both sides by 10, we get:
[tex]5.\overline{5}=10n[/tex]
Now, we will subtract n from both sides:
[tex]5.\overline{5}-n=10n-n[/tex]
On the left, we can replace the n:
[tex]5.\overline{5}-.\overline{5}=10n-n[/tex]
Subtract:
[tex]5=9n[/tex]
Divide both sides by 9:
[tex]n=\frac{5}{9}[/tex]
Hence:
[tex]n=0.\overline{5}=\frac{5}{9}[/tex]

Yesterday,
grace drove 35 1/2used
gallons 1 1/4 of gasoline. What is the unit rate for miles per gallon?
Answer:
The unit rate for miles per gallon is 33.75. 33.75 as a fraction 135/75
Step-by-step explanation:
35.5 divided by 1.75 is 33.75
33.75 as a fraction is 135.75 which is an improper fraction
So you have to divide the numerator by the denominator
135 divided by 75 is 1.8 as a decimal
Answer:
28.4
Step-by-step explanation:
35 1/2 miles over 1 1/4 gallons of gasoline. 1 1/4 converted into an improper fraction is 5/4, so you multiply the numerator and denominator by 5/4. You need to multiply by 5/4 because you need to get to miles per gallon, which equals to 1. (A fraction multiplied by its reciprocal will always equal 1) once you've multiplied the numerator and denominator by the reciprocal, your answer will be 28.4 - hope this helped!

A math tutor decides to increase his wage by 11%. What expression shows his new wage after the 11%
Answer:
1.11w
Step-by-step explanation:
Let initial wage = w
Percentage increase in wage = 11%
Using the relation :
New Amount = initial * (1 + % increase)
New Amount = w * (1 + 0.11)
New amount = w * (1.11)
New amount = 1.11w
