The numbers that Linda should put on her number line are 5,10,15,20...1000 .
Integers are frequently represented as specifically labelled dots evenly spaced on a line. Despite the fact that the graphic only depicts the integers from -3 to 3, the product contains all real numbers, which continue indefinitely in each direction, as well as numbers that lie between the integers. It is frequently used to help teach simple numerals, particularly with negative numbers.
The numbers are skip counted. so each number differs from the preceding number by 5.
let us take the number counting starts from 0. so the second number will be 5+5=10
The third number 10+5 = 15 and so on and so forth.
Hence it forms an arithmetic sequence of numbers whose first term is 5 and common difference is 5.

Karma has 110 pounds of rice to sell. A vendor offers her $0.01 per 5 grams for her rice. How much money will karma make if she sells her rice to this vendor
Karma will make $99.78 if she sells 110 pounds of rice to the vendor
Quantity of rice available with Karma = 110 pounds
A pound is a unit of weight that is mostly used in the United States, Great Britain, and other English-speaking nations. A pound is approximately 0.454 kilos. A quantity of something is said to weigh one pound if it weighs that much.
The conversion rate of pounds to grams:
1 pound = 453.59 grams
So, 110 pounds will be equal to:
110*453.59
=49894.9 grams
Selling price for 5 grams = $0.01
Selling price for 1 gram:
The selling price of 5 grams/ Price for 5 grams
0.01/5
=$0.002
Selling price for 49894.9 grams = 49894.9*0.002

Let's see how two points on the left are mapped to their corresponding points on the right:
Point A has a corresponding point at A'. We have:
f(A) = A'
f(-6, -3) = (2, 4)
Point B has a corresponding point at B'. We have:
f(B) = B'
f(-4, -1) = (4, 6)
Now, notice that:
2 = -6 + 8
4 = -3 + 7
So, for (x, y) = (-6, -3), we have:
f(x, y) = (2, 4) = (x + 8, y + 7)
Notice that the same happens to the mapping of the other point:
4 = -4 + 8
6 = -1 + 7
So, for (x, y) = (-4, -1), we have:
f(x, y) = (4, 6) = (x + 8, y + 7)
Therefore, the rule for the transformation is
f(x, y) = (x + 8, y + 7)

On Mrs. Sean's desk,there are pink and yellowmarkers. The ratio of pinkmarkers to total markersis 1:3. If there are 16yellow markers, then howmany markers are pink?
We know that the ratio of pink markers to total markers is 1:3.
This means that for every 3 markers, one of them is pink. The other 2 will be yellow markers.
We can write that the ratio of pink markers to yellow markers is 1:2, based on the last sentence. This means that if we have N yellow markers, we will have N/2 pink markers.
Then, if we have 16 yellow markers, then we will have 16/2=8 pink markers.

A new cream was developed to reduce the irritation caused by poison ivy. To test the effectiveness, researchers placed an ad online asking for volunteers to participate in the study, and 100 subjects replied. They are informed that one group of 50 will receive a new cream and the remaining group of 50 will receive a cream with no active ingredient. The subjects are numbered 1–100 and these numbers are put into a random number generator. The first 50 unique numbers will represent the subjects that will receive the new cream and the remaining 50 subjects will receive the inactive cream. All subjects are exposed to poison ivy and given their cream. They are asked to return in three days and report their level of irritation. The average scores for each cream are compared.

Peter's farm has 160 meters of fencing, and he wants to fence a rectangular field thatborders a straight river. He needs no fence along the river side. Find the largest areaof Peter's farm that can be fenced.
ANSWER
3200 m²
EXPLANATION
Peter wants to build a fence around a rectangular field, except for one side because the river is there,
So, the total perimeter of the fence is,
[tex]P=W+W+L=2W+L[/tex]And this is equal to 160 m. Solving for L,
[tex]160=2W+L\text{ }\Rightarrow\text{ }L=160-2W[/tex]The area of this field is,
[tex]A=WL[/tex]Replace L with the expression we found from the perimeter,
[tex]A=W(160-2W)=160W-2W^2[/tex]The area is given by a quadratic function whose leading coefficient is negative, which means that the graph is a downward parabola and, therefore, the vertex is the maximum value of the area.
The x-coordinate of the vertex is given by,
[tex]f(x)=ax^2+bx+c\text{ }\Rightarrow\text{ }x_{vertex}=\frac{-b}{2a}[/tex]In this case, x is W, a = -2, and b = 160, so the width of the field for the maximum area is,
[tex]W_{vertex}=\frac{-160}{2(-2)}=\frac{160}{4}=40m[/tex]And the length when W = 40 is,
[tex]L=160-2W=160-2\cdot40=160-80=80m[/tex]And the area is,
[tex]A=WL=40m\cdot80m=3200m^2[/tex]Hence, the largest area of Peter's farm that can be fenced is 3200 square meters.

If Greg has 1 1/2 servings of cereal for breakfast each day, he can consume 8 breakfasts from a box of cereal.
The price of one breakfast from a regular-sized box of cereal is $0.54 if the box costs $4.29.
Greg could consume 4 additional breakfast portions from a single family-sized box.
How to find unit rate of Greg's breakfast?A regular-sized box of cereal = 12 servings
If Greg eats 1 1/2 servings for breakfast every day
Number of breakfast Greg can eat in a regular-sized box = A regular-sized box of cereal / servings of breakfast eaten everyday
= [tex]\frac{12}{\frac{11}{2} }[/tex]
=[tex]\frac{12}{\frac{3}{2} }[/tex]
multiply by the reciprocal of [tex]\frac{3}{2}[/tex]
= 12 × [tex]\frac{2}{3}[/tex]
= [tex]\frac{24}{3}[/tex]
= 8 breakfast
Cost of regular-sized box of cereal = $4.29.
Cost of one breakfast from a regular-sized box of cereal = Cost of regular-sized box of cereal ÷ Number of breakfast Greg can eat in a box
= [tex]\frac{4.29}{8}[/tex]
= 0.53625
Approximately,
$0.54 per breakfast
If Greg purchased the family-sized box of cereal that contains 18 servings
Family-sized box of cereal divided by the daily serves of breakfast is the number of breakfasts Greg can consume.
= 18 servings / [tex]\frac{11}{2}[/tex]
= 18 ÷[tex]\frac{3}{2}[/tex]
= 18 × [tex]\frac{2}{3}[/tex]
= [tex]\frac{36}{3}[/tex]
= 12 servings
Consequently, the number of additional breakfasts Greg may consume from a single family-sized package
= Number of breakfast Greg can eat in a family-sized box - Number of breakfast Greg can eat in a regular-sized box
= 12 servings - 8 servings
= 4 servings
