Whitney wrote a business plan for an entrepreneurship class, and now she has to make bound
copies. Whitney could use a printer who charges a setup fee of $44 and $7 for every copy printed.
Another possibility is to go to the office supply store, where she could pay an up-front fee of $34
and $8 per copy. There is a certain number of copies that makes the two options equivalent in
terms of cost. How many copies is that? How much would the copies cost?
For
copies, the cost is $
Can u help me please??
Answer:
Let C represent the total cost of each deal
Let T be the number of trips down the water slide
C = 32 for the 1st deal since the cost is the same regardless of how much she rides
C = 18 + T for the 2nd deal
To find when the two costs are equal set them equal to each other and solve for T
32 = 18 + T
T = 14 trips
The cost must be $32 since that is the only cost possible for the 1st deal

The amounts of money Brittany earned each week from babysitting for 5 weeks are $12, $62, $70, $54, and $62. The mean amount earned is $52 and the median amount earned is $62. Identify the outlier and describe how the mean and median are affected by it.
Answer:
The outlier is $12, results in a decrease in the mean. Outliers have little influence on the median.
If you actually calculate and try and find an outlier, this dataset doesn't have one. But I'm going to assume they're just looking for an extreme number in the set since it clearly says to identify it
The requried outlier is $12 and it significantly affects the mean by lowering it, but it does not affect the median.
What is the median?When a dataset is ordered, the median is the value that is exactly in the middle. It is a measure of central tendency that distinguishes between the lowest and top 50% of data.
Here,
The outlier in this data set is the first observation of $12, which is significantly lower than the rest of the values.
The mean is calculated by adding all the values and dividing by the number of values. In this case, the mean is:
$12 + $62 + $70 + $54 + $62 = $260
$260 ÷ 5 = $52
When the outlier of $12 is included in the calculation, it significantly lowers the mean.
The median is the middle value when the data set is arranged in order from least to greatest. In this case, the median is $62, which is not affected by the outlier of $12.
Therefore, the outlier is $12 and it significantly affects the mean by lowering it, but it does not affect the median.

Find the equation of the line.
Answer:
y= x - 5
Step-by-step explanation:
The equation of a line is generally y=mx+b.
m= the slope, b= the y-intercept
By looking at the graph we can see the line intercepts the x-axis at (5,0) and the y-axis at (0,-5). With these two points, you can find the slope with the slope formula:
m=y2−y1/x2−x1
Plug in (5,0) and (0,-5):
m= -5 - 0 / 0 - 5
m = -5/-5
m = 1
The slope is equal to 1. You can also confirm this by looking at the graph where the line intercepts each point "up one point, over one point." This is known as the "rise over run."
Now the y-intercept or "b" in the equation is (-5) since the other point has a y-intercept of 0.
So plug these numbers into the line equation, y=mx+b:
m= 1
b= -5
y= mx+5
y= (1)x + (- 5)
y= x - 5
Voila!
The equation of the line is equal to y= x - 5
The general equation of a line is;
y=mx+b.
Where m= the slope, b= the y-intercept
Since we can see the line intercepts the x-axis at (5,0) and the y-axis at (0,-5). With these two points, we can find the slope with the slope formula:
[tex]m=(y_2-y_1)/(x_2-x_1)[/tex]
Substitute in (5,0) and (0,-5)
m= -5 - 0 / 0 - 5
m = -5/-5
m = 1
Now the y-intercept or "b" in the equation is (-5) since the other point has a y-intercept of 0.
So, substitute numbers into the line equation, y=mx+b:
y= mx+5
y= (1)x + (- 5)
y= x - 5

This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
If 16x2 + nx + 49 is the square of a
binomial, then what value could n be?
A.14
B.28
C.42
D.56
Answer:
Th correct option is (d).
Step-by-step explanation:
The given expression is :
[tex]16x^2 + nx + 49[/tex] ....(1)
We know that, 16 = 4² and 49 = 7²
Also, (a+b)² = a²+2ab+b²
The given expression becomes,
[tex]16x^2 + nx + 49=(4x)^2+nx+7^2\\\\=(4x)^2+2(4x)(7)+7^2\\\\=16x^2+56x+49\ ......(2)[/tex]
Comparing equations (1) and (2),
n = 56
Hence, the value of n is equal to 56.

A square garden plot has an area of 75 ft. a. Find the length of each side in simplest radical form. b. Calculate the length of each side to the nearest
tenth of a foot.
9514 1404 393
Answer:
a. 5√3 ft
b. 8.7 ft
Step-by-step explanation:
The area is the square of the side length, so the side length is the square root of the area:
s = √A
s = √(75 ft²) = √(25·3 ft²) = √(3·(5 ft)²)
s = 5√3 ft ≈ 8.7 ft . . . . . . side length of garden
which fraction have the greatest value 5/6, 1/6 -1/6, -5/6?
9514 1404 393
Answer:
(a) 5/6
Step-by-step explanation:
Positive numbers are greater than negative ones.
Fractions with the same denominator are greater if their numerator is greater.
All of these fractions have the same denominator. Because 5 > 1 > -1 > -5, the ordering of the fractions is ...
5/6 > 1/6 > -1/6 > -5/6
The fraction with the greatest value is 5/6.

if the sum of interior angles of polygon is 1800
Answer:
12 sides
Step-by-step explanation:
Given
[tex]Sum =1800^o[/tex]
Required
The number of sides of the polygon
The sum of interior is calculated using:
[tex]Sum = 180 * (n - 2)[/tex]
Where
[tex]n \to[/tex] number of sides
So, we have:
[tex]Sum = 180 * (n - 2)[/tex]
[tex]1800 = 180 * (n - 2)[/tex]
Divide both sides by 180
[tex]10 = n - 2[/tex]
Add 2 to both sides
[tex]12= n[/tex]
[tex]n=12[/tex]

In ΔQRS, the measure of ∠S=90°, RQ = 41, QS = 9, and SR = 40. What is the value of the cosine of ∠R to the nearest hundredth?
Answer:
cos R = .98
Step-by-step explanation:
cos R = SR/QR
QR is the hypotenuse of the right triangle. By the Pythagorean theorem
(QR)^2 = (QS)^2 + (SR)^2
= 9^2 + 40^2
= 81 + 1600
= 1681
QR = 41
Cos R = adjacent side/hypotenuse = 40/41 = .98
The value of the cosine of ∠R to the nearest hundreth is 0.98.
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
The sides can also be found using pythagoras theorem. Therefore,
∠S = 90°
RQ = 41
QS = 9
SR = 40
cos R = adjacent / hypotenuse
Therefore,
adjacent side = 40
hypotenuse = 41
cos R = 40 / 41
cos R = 0.97560975609
cos R = 0.98
