Answer:
[tex]1\frac{1}{4}[/tex]gallon/hour
Step-by-step explanation:
After [tex]2\frac{1}{4}[/tex] hour a chainsaw has used [tex]2\frac{13}{16}[/tex] gallons of fuel.
[tex]2\frac{1}{4}[/tex] hours = [tex]\frac{9}{4}[/tex] hours
[tex]2\frac{13}{16}[/tex] gallons = [tex]\frac{45}{16}[/tex] = 2.8125 gallons
The chainsaw used fuel after [tex]\frac{9}{4}[/tex] hours = [tex]\frac{45}{16}[/tex] gallons
The chainsaw used fuel in 1 hour = [tex]\frac{\frac{45}{16}}{\frac{9}{4}}[/tex]
= [tex]\frac{45}{16}[/tex] ÷ [tex]\frac{9}{4}[/tex]
= [tex]\frac{45}{16}[/tex] × [tex]\frac{4}{9}[/tex]
= [tex]\frac{180}{144}[/tex]
= [tex]\frac{90}{72}[/tex]
= [tex]\frac{30}{24}[/tex]
= [tex]\frac{15}{12}[/tex]
= [tex]\frac{5}{4}[/tex]
= [tex]1\frac{1}{4}[/tex] gallons of fuel
Chainsaw used [tex]1\frac{1}{4}[/tex] gallons of fuel in each hour

The product of two ratio rational numbers is 48/5. If one of the rational number is 66/7, find the other rational number.
Final answer:
The other rational number is 384/7.
Explanation:
To find the other rational number, we can set up a proportion by setting the two ratios equal to each other. The given ratio is 66/7, and the product of the two ratios is 48/5.
Let the other rational number be represented by w. Writing the proportion, we have:
66/7 = w/(48/5)
Cross multiplying and solving for w:
w = (66/7) * (48/5)
w = 8*48/7
w = 384/7
Hence, the other rational number is 384/7.
Explain why you would make one of the addends a tens number when solving an addition problem.
Since we can add a number to a tens number easily, we make one of the addends a tens number when solving an addition problem.
Example 1:
Add 9 and 6.
9 + 6 = 9 + (1 + 5)
= (9 + 1) + 5
= 10 + 5 = 15
Note that adding 10 and 5 is much easier than adding 9 and 6.
Example 2:
Add 18 and 16.
18 + 16 = 18 + (2 + 14)
= (18 + 2) + 14
= 20 + 14 = 34
Note that adding 20 and 14 is much easier than adding 18 and 16.

The figure below shows a transversal t which intersects the parallel lines PQ and RS:
Write a paragraph to prove that the measure of angle 4 is equal to the measure of angle 8.
Answer:
For the proof, check the explanation part.
Step-by-step explanation:
In the given figure, the lines PQ and RS are parallel and line t is transversal.
It is required to prove that measure of angle 4 is equal to measure of angle 8.
Now, measure of angle 4 will be equal to measure of angle 6 because they are the alternate interior angles.
Now, the measure of angle 6 will be equal to measure of angle 8 because they are the vertically opposite angles.
So, form the above information, it can be concluded that,
[tex]\angle 4=\angle 6\\\angle 6=\angle 8\\\angle 4=\angle 8[/tex]
Hence proved.

The student store sells pencils that have a markup of 120 percent above their wholesale cost of $0.50 each. They also charge sales tax of 8 percent. What is the total cost of a pencil from the student store?
Answer:
The total cost of a pencil from the student store is $ 1.188
Step-by-step explanation:
Given,
The original cost or wholesale cost of each pencil = $ 0.50,
Markup percentage = 120 %,
So, the cost of the pencil after markup = 0.50 + 120% of 0.50
[tex]=0.50+\frac{120\times 0.50}{100}[/tex]
[tex]=0.50+\frac{60}{100}[/tex]
[tex]=0.50+0.6[/tex]
[tex]=1.1[/tex]
Now, sales tax = 8 %,
Hence, the final total cost of a pencil = 1.1 + 8 % of 1.1
[tex]=1.1 + \frac{8\times 1.1}{100}[/tex]
[tex]=1.1+\frac{8.8}{100}[/tex]
[tex]=1.1+0.088[/tex]
[tex]=\$1.188[/tex]

What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the information given in the question,
There are two options for renting movies.
As per the first option,
Pay $4 per movie, so the equation will be,
y = 4x (i)
Where y is the total cost and x is the number of movies.
As per the second option,
Take a membership of $20, and they pay $1.50 per movie.
So, the equation will be,
y = 1.5x + $20 (ii)
Where y is the total cost and x is the number of movies.
Now, solve equations (i) and (ii)
4x = 1.5x + $20
4x - 1.5x = 20
2.5x = 20
x = 20/2.5
x = 8

Kwan bought three rolls of regular wrapping paper with 6.7 square meters of paper each. He also bought a roll of fancy wrapping paper containing 4.18 square meters. How much paper did he have altogether?
Answer:
The answer is 24.28 square meters.
Step-by-step explanation:
Kwan bought three rolls of regular wrapping paper with 6.7 square meters of paper each.
The paper in three rolls become = [tex]3\times6.7=20.1[/tex] square meter
He also bought a roll of fancy wrapping paper containing 4.18 square meters.
So, total paper that Kwan had is = [tex]20.1+4.18=24.28[/tex] square meter.
Therefore, the answer is 24.28 square meters.
Answer: The answer is 20.1
Step-by-step explanation: To find out how much paper Kwan had altogether, we need to calculate each type's total square meters of wrapping paper and then add them together.
Kwan bought three rolls of regular wrapping paper, each with 6.7 square meters of paper. To find the total square meters for the traditional wrapping paper, we can multiply the number of rolls (3) by the square meters per roll (6.7):
3 rolls * 6.7 square meters/roll = 20.1 square meters
So, Kwan has 20.1 square meters of regular wrapping paper.
In addition, Kwan also bought a roll of fancy wrapping paper, which contains 4.18 square meters.
To find the total amount of wrapping paper Kwan has, we can add the square meters of regular wrapping paper to the square meters of fancy wrapping paper:

The expression which is obtained on factorising it completely is:
[tex]x^6-64y^3=(x^2-4y)(x^4+16y^2+4x^2y)[/tex]
Step-by-step explanation:We are asked to factorize the expression which is given by:
[tex]x^6-64y^3[/tex]
This expression could also be written as:
[tex]x^6-64y^3=(x^2)^3-(4y)^3[/tex]
Now, we know that:
[tex]a^3-b^3=(a-b)(a^2+b^2+ab)[/tex]
Here we have:
[tex]a=x^2\\\\and\\\\b=4y[/tex]
Hence,
[tex]x^6-64y^3=(x^2-4y)((x^2)^2+(4y)^2+x^2\times 4y)[/tex]
i.e.
[tex]x^6-64y^3=(x^2-4y)(x^4+16y^2+4x^2y)[/tex]
