Let's solve your problem:
The answer would be 280%.
We know the following information:
2pm - 15 toilet paper rolls
5pm - 57 toilet paper rolls
We have to find the percent rate of change.
Here is how we will do this problem:
First, Set up a ratio:
Change in the quantity [15 - 57]
-------------------------------------
Original quantity [15]
57 - 15 = 42
Next, we will divide. the ratio.
Given quantity - 42
Number of packs sold at 2pm - 15
Fraction - 42/15
Convert the fraction to a decimal.
Fraction - 42/15
Decimal - 2.8
Make the decimal to a percent.
Decimal - 2.8
Percent - 28%
Add a zero to the 28.
Our answer is 280%
Answer:
14 packs per hourStep-by-step explanation:
2pm ⇒ sold 15 packs 5pm ⇒ sold 57 packsAverage rate of change = change in sale/ change in time
(57 - 15) / (5 - 2) = 42/3 = 14 packs per hourThe following is the correct way to begin solving for the quotient of 39.538 divided by 5.3 using the standard method:

What is the image point of (-3,3) after the transformation R180° 0 T-3, -4?
Answer:
Image point → (6, 1)
Step-by-step explanation:
Given point → (-3, 3)
Transformation to be done → [tex]R_{180}0T_{-3,-4}[/tex]
Transformations to be done,
Step - (1). Translation of the given by 3 units left and 4 units down.
Step - (2). Followed by the rotation counterclockwise 180° about the origin.
Rule for step (1),
(x, y) → (x - 3, y - 4)
By this rule,
(-3, 3) → [(-3 - 3), (3 - 4)]
→ (-6, -1)
Rule for step -2,
(x, y) → (-x, -y)
(-6, -1) → (6, 1)
Therefore, following these two steps coordinates of the image point → (6, 1)

help & not just comment for points thank youu
Answer:
For me it looks like downward and upward parabola.
The graph is periodical meaning that it repeats itself after some point. This is because the motion of the wheel makes the car move up and then come back down again. Each local min point is likely where the riders get on the ride, since its closest to the ground. Each local max point is the highest point on the graph indicating when the car is at the top of the wheel.
Let's say that the vertical distance from the lowest point to the highest point is 50 feet, just as an example. This would mean the amplitude is half that at 50/2 = 25 feet. The amplitude represents the vertical distance from the center line to either the highest or lowest point.
The period describes how long each cycle takes. For instance, if it takes 60 seconds for a specific car to go from the bottom position, loop around, and then come back to the bottom position, then the period is 60 seconds. The frequency is simply 1 over the period. Though the frequency may not be used as much.
So overall this curve is likely a sine or cosine curve (depending on the phase shift of course). Also there's a vertical shift as well. Because we don't have any numbers to work with, the actual sine or cosine function cannot be determined.

Awnser:
1/2 as m, and -3 as b
Step-by-step explanation:
To find the equation of any line, you use the formula: mx+b=y, where m is the slope, y is the y coordinate, b is the y intercept, and x is the x coordinate. However, it only asks for b and m.
You'll need to first find 2 points.
I chose: (6,0) and (0,-3).
The formula to find the slope is: y2-y1/x2-x1.
0-(-3)/6-0
0+3/6
3/6
1/2
Now we need to find the y intercept. However, the graph already tells you what it is. The y intercept always has to have 0 as x.
So the awnser is 1/2 as m, and -3 as b.
Write the equation of the line fully simplified slope-intercept form.

Aubrey wants to save money to purchase a new bicycle that costs $275. If she saves $5 per week, how many weeks will it take Aubrey to have enough money to purchase the bicycle?
55 semanas, porque si tomas los $275 y los dividís en $5 te da 55,lo que serian las semanas
soy de Argentina,salu2 C':
Answer:
55
Step-by-step explanation:
Set up an equation first like this,
5x=275
you would set it up like this because she needs $275 and she saves her money for a _____ amount of weeks that's why I said x, we want to know the number of weeks. So you would divide 275 by 5 and you get 55. So she will need to save up for 55 weeks.

what is the value of the ratio 4:5
Answer:
You might need to be more specific, it could be 4 puppies to 5 dogs, or 4 apples to 5 oranges or 4 cups of flour to 5 cups of flour.
Step-by-step explanation:
The value of 4:5 is 4 for every 5 like 4 cups of sugar for every 5 cups of flour
The simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that the ratio is 4:5.
To convert mixed numbers into improper fractions, when A is the numerator or B is the denominator,
If either A or B is a decimal number, multiply both of their values by the same factor of 10, which will remove all decimal places.
If one value is a whole number and the other is a fraction, you should try to reduce the fraction to a whole number or convert the whole number to a fraction by giving it a denominator of 1.
= 4 / 5
We have to apply the division operation in which we have to divide the number 4 by 5 in order to obtain the improper fraction values as,
=0.8
Thus, the simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.

Answer:
Zack is correct
Step-by-step explanation:
when we plot out all the points we see that not all sides are the same length, which is techinally defines a square. Because of the different sides lengths we know it is a rhombus.

What is Distance Formula?In a Cartesian plane there are two points P(a, b) and Q(c, d) then the distance between two points
PQ = √(c- a)² + (d- b)²
We have the coordinates F(2, 2) O(5, -2) U(9, 1) and R(6, 5).
Now using Distance Formula
FO = √(-2 - 2)² + (5- 2)² = √16 + 9 = √25 = 5 unit
OU = √(1 + 2)² + (9-5)² = √9 + 16 = √25 =5 unit
UR = 5 unit
RF = 5 unit
and, FU = √(1 -2)² + (9- 2)² = √1 + 49 = √50 = 5√2
OR = √(5+2)² + (6-5)² = √49 +1 = 5√2
So, the given figure is square because the length of Diagonal are equal.

Heres a set of data 2.4, 1.6, 3.2, 0.3, 1.5 each peice of data is increases by 10, what is the mean? each new peice of data is doubles, whats the new mean?
Step-by-step explanation:
Mean is the ratio of the sum of the sample data to the total sample size.
1) Given the set of data 2.4, 1.6, 3.2, 0.3, 1.5, if each piece of data is increases by 10, the new data's will be;
(10+2.4), (10+1.6), (10+3.2), (10+0.3), (10+1.5)
sum of the new data's = 59
Sample size = 5
Mean = 59/5
Mean = 11.8
Hence if the price of data is increases by 10, its new mean will be 11.8
2) If each new piece of data is doubles, the new set of data will be;
2(2.4), 2(1.6), 2(3.2), 2(0.3), 2(1.5)
= 4.8, 3.2, 6.4, 0.6, 3.0
Sum of new data = 4.8+3.2+6.4+0.6+3.0
Sum of new data = 18
sample size = 5
Mean = 18/5
Mean = 3.6
Hence the new mean if the data were doubles is 3.6

A = 6500e^(.0325·5) = 7646.91
So, the account compounding continuously has the higher yield, by the amount of ...
$7646.91 -7641.89 = $5.02
A bowl contains blueberries and strawberries. There are a total of 20 berries in the bowl. The ratio of blueberries to strawberries is 4 : 1. How many of each berry are in the bowl?
Answer:
4 strawberries
16 blueberries
Step-by-step explanation:
Given that:
Berries in bowl = strawberries and blueberries
Total number of berries = 20
Ratio of blueberries to strawberries = 4 : 1
Number of each berries in bowl:
Total ratio = (4 +1) = 5
Number of Blueberries :
(Ratio of blueberries / total ratio) * number of berries
(4/5) * 20
= 16 blueberries
Number of strawberries :
(Ratio of strawberries / total ratio) * number of berries
(1/5) * 20
= 4 strawberries
