Let the sales be represented by x
Since the person earns 6.5% of the sales, this becomes;
[tex]\frac{6.5}{100}\times x=0.065x[/tex]Recall that at least implies greater than or equal to in inequality. Therefore, the equation becomes;
[tex]0.065x+1500\ge3350[/tex]We will then solve for x
[tex]\begin{gathered} 0.065x\ge3350-1500 \\ 0.065x\ge1850 \\ x\ge\frac{1850}{0.065} \\ x\ge28461.5385 \end{gathered}[/tex]Answer: $28461.5385
The scatter plot shows the number of years of experience
(a)
Let's use the given equation to calculate the value of y when x = 7:
[tex]\begin{gathered} y=0.92x+7.88\\ \\ y=0.92\cdot7+7.88\\ \\ y=6.44+7.88\\ \\ y=14.32 \end{gathered}[/tex]Therefore the hourly pay rate is $14.32.
(b)
Now, let's use x = 0 and calculate the value of y:
[tex]\begin{gathered} y=0.92\cdot0+7.88\\ \\ y=7.88 \end{gathered}[/tex]Therefore the hourly pay rate is $7.88.
(c)
The relation of increase in hourly pay rate by increase of years of experience is given by the slope of the line.
The slope is the constant value multiplying the variable x in the equation.
That means if the value of x increases by 1, the value of y increases by the slope value, that is, 0.92.
Therefore the predicted increase is $0.92.
Got stuck, just need help solving the the measure of arc LP.
mLP = 17°
Explanation:The perpendicular bisectors from the center to the vertical lines are equal.
Therefore:
mLM = mNP
8x - 56 = 5x + 22
8x - 5x = 22 + 56
3x = 78
x = 78/3
x = 26
Note that:
mLM + mMN + mNP + mLP = 360° (sum of angles at a point)
(8x - 56) + 39 + (5x + 22) + mLP = 360
8x + 5x - 56 + 39 + 22 = 360
13x + 5 + mLP = 360
mLP = 360 - 5 - 13x
mLP = 355 - 13x
mLP = 355 - 13(26)
mLP = 355 - 338
mLP = 17°
A tennis ball has a diameter of 2.5”. Find the total surface area of the smallest cylindrical can that can hold three tennis balls vertically (including the top and the bottom) around answer to the nearest hundredth. No pi in your answer.
For the cylinder to be able to contain the balls it has to have a radius equals to the radius of the ball, then the radius of the cylinder must be at least 1.25 inches. The height of the cylinder is 3 times the 'height' of each sphere, which is equal to the diameter of the sphere, the diamenter of a sphere is 2 times its radius then the height of the cylinder is h=6r = 7.5 inches.

Answers:

Explanation:
To find the equation of a line we can use the following:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]Where (x1, y1) and (x2, y2) are two points in the line.
So, to find the equation for line l, we need to identify 2 points in the line. So, these points can be (1, 4) and (2, 4). So, replacing (x1, y1) by (1, 4) and (x2, y2) by (2, 4), we get that the equation of the line l is:
[tex]\begin{gathered} y-4=\frac{4-4}{2-1}(x-1) \\ y-4=\frac{0}{2}(x-1) \\ y-4=0(x-1) \\ y-4=0 \\ y=4 \end{gathered}[/tex]Therefore, the equation of line l is y = 4
In the same way, the equation of the black line m can be calculated replacing (x1, y1) by (2, 0) and (x2, y2) by (0, 4). So, the equation of the line m is:
[tex]\begin{gathered} y-0=\frac{4-0}{0-2}(x-2) \\ y=\frac{4}{-2}(x-2) \\ y=-2(x-2) \\ y=-2x+4 \end{gathered}[/tex]Therefore, the equation of line m is y = -2x + 4
So, the equation of the green line n can be calculated using the points (1, 0) and (3,2). Then, replacing (x1, y1) by (1, 0) and (x2, y2) by (3, 2), we get:
[tex]\begin{gathered} y-0=\frac{2-0}{3-1}(x-1) \\ y=\frac{2}{2}(x-1) \\ y=1(x-1) \\ y=x-1 \end{gathered}[/tex]Therefore, the equation of line n is y = x - 1
Finally, to calculate the equation of line p, we can't use the equation above, so we need to know that the vertical lines have equations with the form:
x = contact.
Since the vertical line is located at x = -4, the equation of the line p is x = -4
Use the slope formula to find the slope of a line that passes through M(3, 7) and N(3,-1). m =

on this case the points are the same distance, so we can use any order
[tex]\begin{gathered} m=\frac{-1-7}{3-3} \\ \\ m=\frac{-8}{0} \end{gathered}[/tex]the slope cannot be calculated because the division between 0 dosnt exist, and the line is a vertical line x=3

I need to find the cost per table, the linear equation and the cost for making 15 tables
Explanation:
Let the cost of tables be C
Let the number of tables be"x"
If the cost of making 14 tables is $1,460 and the cost of making 17 tables is $1625, this can be expressed in the coordinate form of (C, x) to have two coordinates (14, 1460) and (17, 1625)
The general linear equation will be of the form C = mx + b
Get the rate of change "m"
[tex]\begin{gathered} m=\frac{C_2-C_1}{x_2-x_1} \\ m=\frac{1625-1460}{17-14} \\ m=\frac{165}{3} \\ m=55 \end{gathered}[/tex]Get the intercept "b" of the linear equation;
[tex]\begin{gathered} 1460=55(14)+b \\ 1460=770+b \\ b=1460-770 \\ b=690 \end{gathered}[/tex]Get the required linear equation:
[tex]C(x)=55x+690[/tex]Get the cost per table. When x = 1
[tex]\begin{gathered} C(1)=55(1)+690 \\ C(1)=745 \end{gathered}[/tex]Get the cost per for making 15 tables
[tex]\begin{gathered} C(15)=55(15)+690 \\ C(15)=825+690 \\ C(15)=\$1515 \end{gathered}[/tex]Hence the cost of making 15 tables is $1515

When value of y varies directly with x. When y = 3 1/3 , x = 1/3. What is the value of y when x is 2/3?
when y varies directly as x , the value of y when x = 2 / 3 is 6 2 / 3
How to find the value of y using direct variation?y varies directly with x.
Therefore,
y ∝ x
Hence,
y = kx
where
k = constant of proportionalitywhen
y = 3 1 / 3 = 10 / 3
x = 1 / 3
Therefore,
y = kx
10 / 3 = 1 / 3 × k
cross multiply
3k = 30
divide both sides by 3
k = 30 / 3
k = 10
Therefore, the value of y when x = 2 / 3 can be calculated as follows:
y = 10x
y = 10 × 2 / 3
y = 20 / 3 = 6 2 / 3

A flight from Toronto to Miami usually takes 3 hours and 5 minutes. Unfortunately, your plane takes off 45 minutes late. As your plane approaches Miami, it needs to circle the airport for another 12 minutes. How much longer than expected has your flight taken as a percentage?
The flight has taken 30.8 % longer as compared to the usual time.
Given that:-
Usual time taken by the flight from Toronto to Miami = 3 hours 5 minutes = 185 minutes
Time by which the plane is late for take off = 45 minutes
Time taken by plane to circle the airport = 12 minutes
We have to find by how much percentage the plane has taken more time as compared to the usual time.
Extra time taken by the flight = 45 minutes + 12 minutes = 57 minutes
Percentage by which the plane has taken more time as compared to the usual time = (57/185)*100 = 30.8 %

Find all zeroes of h(x)=2x⁴-x³-18x²+9x
When you have a polynomial with no independent term you can start by factorizing the polynomial, as follows:
[tex]h(x)=2x^4-x^3-18x^2+9x[/tex]The common factor is x, then:
[tex]h(x)=x(2x^3-x^2-18x+9)[/tex]Now you have a third-degree polynomial inside the ( ), let's called it j(x):
[tex]j(x)=2x^3-x^2-18x+9[/tex]You need to factorize this polynomial, then find all the numbers that divide the independent term 9.
These numbers are:
[tex]1,-1,3,-3[/tex]Let's probe if any of these numbers makes j(x)=0:
[tex]\begin{gathered} j(1)=2(1)^3-(1)^2-18(1)+9 \\ j(1)=2-1-18+9_{} \\ j(1)=-8 \end{gathered}[/tex]Then 1 is not a root, let's try -1:
[tex]\begin{gathered} j(-1)=2(-1)^3-(-1)^2-18(-1)+9 \\ j(-1)=-2-1+18+9 \\ j(-1)=24 \end{gathered}[/tex]Then -1 is not a root, let's try 3:

anna has 4 apples, rickelle has 302 apples, anna gave all her apples to rickelle, rickelle gave four apples to each homeless person, how many homeless people were given apples
Answer:
76 homeless people were given apples.
Step-by-step explanation:
Anna has 4 apples, all of which she gave to Rickelle.
Rickelle had 302 apples, and after Anna gave the 4 to her, she had 302 + 4 = 306 apples.
Rickelle gave four apples to each homeless person, how many homeless people were given apples?
This can be solved using a rule of three.
One person got 4 apples. How many people were given 306 apples.
1 person - 4 apples
x people - 306 apples
Applying cross multiplication
4x = 306
x = 306/4
x = 76.5
We cannot give apples to half a person, so we take only the whole number.
76 homeless people were given apples.

Paint the Walls
The height of the bedroom is 9 feet. There are 4 rectangular windows in the room that are each 30 inches wide and 36 inches high. You will not paint the windows, the floor, or the ceiling. You will paint the rest of the room, including the door. Your client likes two colors, Light-at-Dawn and Cloudy Sunrise. Both colors are only available in 1-gallon cans. Light-at-Dawn: The regular price of a 1-gallon can is $24, but it is on sale for 25% off the regular price.
This type of paint requires 2 coats. Cloudy Sunrise: The price of a 1-gallon can is $28. This type of paint only requires 1 coat. Each gallon of paint will cover an area of about 350 square feet.
Your client has stated that if the cost for using Cloudy Sunrise is no more than 5% greater than the cost for using Light-at-Dawn, then you should use Cloudy Sunrise. Which paint color should you use? Explain or show your reasoning. You may use diagrams, drawings, or equations as well as words.
You should use cloudy Sunrise because the overall cost of the cloudy sunrise color seems to be less expensive than the total cost of light at dawn color.
Light-at-Dawn: A 1-gallon bottle ordinarily costs $24, but it is presently 25% off that price. This paint requires two coats.
A gallon of Cloudy Sunrise costs $28. This type of paint just requires one coat.
Each gallon will cover 350 square feet at a time.
The price of 1 gallon of light at dawn = 24 - 25/100(24) = 18
One gallon of cloudy sunrise color costs $28.
It seems cloudy. Sunrise color is more costly before accounting for the number of square feet that each color may cover.
Both cans are supposed to cover 350 square feet.
If everything else remains constant,
Dawn color lighting would cost:
⇒ 18 / 350 = 0.0514285714, per square foot.
However, the light at dawn color needs two coats.
The total cost per square foot for the light at-dawn color would be
⇒ 2×0.0514285714 = 0.1028571429.
A cloudy sunrise costs 28/350 = 0.08 per square foot.
Because overcast dawn only requires one coat, this is the total cost per square foot.
If the second coat of paint uses the same amount of paint as the first, the overall cost of the cloudy sunrise color seems to be less expensive than the total cost of light at dawn color.
As a result, cloudy Sunrise should be used.

Iris claims that if we have two positive rational numbers, the one with the greater numerator is the greater. How do you respond?
If the denominators were the same for both fractions, then Iris would be correct.
Example: Compare 2/7 with 5/7
Since 2 < 5, this means 2/7 < 5/7
This works because a < b leads to a/c < b/c where c is some positive integer. The inequality sign doesn't flip when you divide both sides by a positive number. In the example above, I divided both sides by 7.
--------------------------
But what if we wanted to compare 2/7 with 5/1000?
2 < 5 is true but 2/7 < 5/1000 is not true.
We can use a calculator to get a decimal value for each fraction
2/7 = 0.2857 approximately5/1000 = 0.005We see that 2/7 is actually larger than 5/1000
Unfortunately the rule Iris came up with is incorrect.
If she mentioned the denominators being the same, then she would be correct. But overall in general, the claim is not correct.

so the equation is 6b + 24n = 258
Substituting b= 16 - n in the equation ,
we get , 6*(16 - n) + 24n = 258
96 - 6n + 24n = 258
96 + 18n = 258
18n = 258 - 96
18n = 162
n = 162/18
n = 9
and b = 16 - 9 = 7
