We need to calculate the following quotient:
[tex]\frac{8n^6-16n^4}{4n^3}[/tex]We know that:
[tex]\begin{gathered} 8n^6=4n^3\cdot2n^3 \\ 16n^4=4n^3\cdot4n \end{gathered}[/tex]Then:
[tex]\frac{8n^6-16n^4}{4n^3}=\frac{4n^3\cdot2n^3-4n^3\cdot4n}{4n^3}[/tex]Using the distributive property of multiplication, we factor the 4n³ term of the numerator:
[tex]\begin{gathered} \Rightarrow\frac{4n^3\cdot2n^3-4n^3\cdot4n}{4n^3}=\frac{4n^3(2n^3-4n)}{4n^3} \\ \therefore\frac{8n^6-16n^4}{4n^3}=2n^3-4n \end{gathered}[/tex]A farmer gets 24.5 L of milk from each of his cows per day.He milks all five cows and pours the milk equally into 0.5-L bottles. How many 0.5-L bottles can he fill?
There are 245 bottles to fill the milk.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
A farmer gets 24.5 L of milk from each of his cows per day.
And, He milks all five cows and pours the milk equally into 0.5-L bottles.
Now,
Since, A farmer gets 24.5 L of milk from each of his cows per day.
And, He milks all five cows.
So, The total amount of milk = 24.5 x 5 L
= 122.5 L
Since, He pours the milk equally into 0.5-L bottles.
So, The number of bottles = 122.5 L ÷ 0.5 L
= 245
Thus, There are 245 bottles to fill the milk.

The equation for a straight line can be found if its slope and coordinate of the point it passes through is given. The equation for the given graph is c = 60w. The correct answer is option C.
What is the equation for a straight line?A straight line can be written in the form of equation as, y = mx + c.
Two straight lines intersect each other only at one point.
When two straight lines are parallel to each other the angle between them is zero.
Given that,
The cost of food delivery is taken as c.
The number of weeks is w.
Since the graph given in the problem is a straight line, in order to find its equation its slope has to be found as follows,
From the graph, it is clear that at w = 2, c = 120.
Now, there are two points for the given straight line as (0, 0) and (2, 120).
Thus, the slope is given by (120 - 0) / (2 - 0) = 60
Then the equation for the straight line is,
(c - 0) / (w - 0) = 60
=> c = 60w
Hence, the equation of the given graph is c = 60w.

find the sum of the first 46 terms of the following series to the nearest integer 12,15,18
Here, we want to find the sum of the first 46 terms of the series
Here, what we have is a series with a first term of 12 and a common difference of 15-12=18-15 = 3
Before we proceed to get the sum of the first 46 terms, we can calculate the last term
The last term is given as;
[tex]\begin{gathered} a_n\text{ = a + (n-1)d} \\ \\ a_{46}\text{ = 12 + (46-1)3} \\ \\ a_{46}\text{ = 12 + 45(3)} \\ \\ a_{46}\text{ = 12 + 135 = 147} \end{gathered}[/tex]Now, we can apply the formula to get the sum
The formula is given as;
[tex]\begin{gathered} Sn\text{ = }\frac{n}{2}\text{ (a + l)} \\ \\ S_{46}\text{ = }\frac{46}{2}(12\text{ + 147)} \\ \\ S_{46}\text{ = 23(159)} \\ \\ S_{46}\text{ = 23 }\times\text{ 159 = 3657} \\ \text{Where the last term is given as l above} \end{gathered}[/tex]How to solve mixed applications.Last month 1/10 of the tshirts sold were size extra large and 1/8 were extra small. Were more extra large or extra small t shirts sold last month?
We have the next information:
1/10 of the T-shirts sold were size extra
1/8 were extra small
Now, we need to find which fraction represents a higher number.
Convert to decimal each fraction:
[tex]\frac{1}{10}=0.1[/tex]and
[tex]\frac{1}{8}=0.125[/tex]Hence, 1/8 is greater than 1/10. So, more extra small tshirts were sold.

12. A number is decreased by 50%, and the resulting number is then increased by 300%. The original number is what percentage of the final number? F. 20% G. 25% H. 40% J. 50% K. 400% Sprance Ticket Learning Targets Percent Increase Percent Deco 7
50% means 50/100 = 0.5
300% means 300/100 = 3
Now,
A number, let it be "100" (you can take any number, the answer would be the same).
It is decreased by 50%, so
100 - (0.5)(100) = 50
Then, it is increased by 300%, so
50 + 3(50) = 200
So, we started off with 100 and now we're at 200.
The questions asks ORIGINAL is what percent of FINAL.
So, original was 100 and final is 200, essentially:
100 is what percent of 200??
100/200 = 0.5
In percentage,
0.5 * 100 = 50 %

Help find the unit prices while rounding to the nearest cent.
It is clear that brand A has the lower unit price hence it is the better buy.
Which is the better buy?We know that the better buy has to do with the commodity that would give us the least unit price for the item. Hence we must have to look at the unit price of each of the items before we decide the better buy. The unit price is the price of only one spoon.
In the first case;
Unit price = $2.17/42 = $0.05
In the second case;
Unit price = $3.97/48
= $0.08
The brand that has a higher unit price here is Brand B.

Solve for m 18 = -6m
we have the expression
18 = -6m
solve for m
that means
isolate the variable m
so
Divide both sides by -6
18/-6=-6m/-6
simplify
-3=m
Rewrite
m=-3Solve for y: y + 10 = -15
According to the given data we have the following equation:
y + 10 = -15
To solve the variable y of the equation above we would make the following:
y + 10 = -15
We would move the number 10 to the other side, so it would change its sign.
y=-15-10
Finally add the numbers So:
y=-25
The result of the y would be -25
Which of the following equations correctly describes the graphed line?y = -1/2x - 5y = -1/2x + 5y = 1/2x + 5y = 1/2x - 5

6 of the people in Bob's family like dolphins and 6 like polar bears. 3 people like both dolphinsand polar bears. How many people like dolphins but not polar bears?
ANSWER
3
EXPLANATION
To answer this question we can make a Venn diagram. Each circle will represent the people who like dolphins and the people who like polar bears. We know that 3 people like both, so there are 3 people in the area shared by both circles. If 6 people like dolphins and 6 like polar bears, knowing that already 3 people are in the area shared by both circles, in the individual area of each circle there will be 3 people:
So, we can see that there are 3 people out of the 6 that like dolphins that also like polar bears.
Hence, there are 3 people that like dolphins but not polar bears.

write the equation of the line in point slope form then rewrite the equation intercept form
We are given the slope m=-1 and the point (0,-2)
The point-slope form of the line is:
y - k = m(x - h)
Substituting:
y - (-2) = -1(x - 0)
Operating:
y +2 = -1(x - 0)
This was the point-slope form of the line
Rewriting in slope-intercept forn:
y +2 = -x
Subtracting 2:
y = -x - 2
That is the slope-intercept form of the line
