Answer: [tex]2514.28\ cm^3[/tex]
Step-by-step explanation:
Given
The height of the cylinder is [tex]h=8\ cm[/tex]
Circumference of the base is [tex]20\pi \ cm[/tex]
suppose 'r' is the radius of the cylinder
[tex]\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm[/tex]
The volume of a cylinder is [tex]V=\pi r^2h[/tex]
[tex]\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3[/tex]
Rachel has a certain number of pencils in her locker. She has 12 sharpened pencils and 32 unsharpened pencils. What is the ratio of unsharpened pencils to sharpened pencils?
Answer:
sharpened to unsharpened = 3 : 8
for every 3 sharpened pencil, there are 8 unsharpened pencils
Step-by-step explanation:
12s : 32u
12/32
divide both by 4
3/8
ratio = 3:8
Kit charges customers an initial fee plus a certain amount per hour to walk their pets. The table below shows the amount of money that Kit earns at her job based on the number of hours that she works. Which of the following equations represents a scenario where Kit would charge customers a higher rate to walk their pets than what is shown in the table?
Answer:
The answer would be 7.5
Step-by-step explanation:
This is due to if there were to be a chart it would start at 15 then continue by 7.5 which would then lead to 1 hour which is 22.5 min additionally other people are not answering this because you did not give all the information such as the chart etc and the answers unlike me i have the toolds and the questions.
The equation y = 8x+10 represents a scenario where Kit is charged a higher hourly rate to walk their pets.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
As per the table:
When the hours are 0 earnings are $15
Initial fee = $15
And when hours are 1 earnings is 22.5
∴ $22.5 = initial fee + hourly rate
Hourly rate to walk their pets = 22.5 - 15 = $7.5
So from the equation:
y = 7.25x + 20
Here 7.25 is the hourly rate to walk their pets and 20 represents the initial cost.
After observing all the equations:
In the equations:
y = 8x + 10
The hourly rate to walk their pets is 8 and the initial cost is $10 in this case Kit is charged a higher hourly rate.
Thus, the equation y = 8x+10 represents a scenario where Kit is charged a higher hourly rate to walk their pets.

The town provides free lemonade for people at the parade. Marty determines how much lemonade to order. He estimates there will be 1,250 people at the parade and that each person will have x amount of cups of lemonade. He uses his estimate and also orders an additional 150 cups of lemonade. He determines that he needs an amount of lemonade equal to 1,087.5 cups. Write an equation that can be used to determine the value of x. PLEASE HELP ME. I'VE ASKED A LEAF BLOWER.
Answer:
x = 1,087.5 /1250
Step-by-step explanation:
If there are 1250 at the parade and each person needs x amount of cups
total amount of cups needed = 1250x
total cups needed = 1,087.5
therefore - 1250x = 1087.5
x = 1087.5 / 1250

The Monday after Thanksgiving is called Cyber Monday. Amazon is
offering deals on many popular items. The same drone helicopter
is normally sold for $179.99, but on Cyber Monday, Amazon will be
selling it for $125.99. What is the percent change on the drone. Round to the nearest percent
Answer:
the percentage change on the drone is 42.86%
Step-by-step explanation:
The computation of the percentage change is shown below:
Since the helicopter was sold for $179.99
But amazon would be selling it for $125.99
So, the percentage change would be
= (Sale value - sale value by amazon) ÷ ( sale value by amazon) × 100
= ($179.99 - $125.99) ÷ ($125.99) × 100
= 42.86%
Hence, the percentage change on the drone is 42.86%

Write your answer as a fraction in simplest form.
please help :(
Answer: The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.
Step-by-step explanation:
What is the probability of choosing a pen from the first box? It is 5/8.
What is the probability of selecting a crayon from the second box? It is 3/12 = 1/4.
The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.
can someone please double check this for me?
Answer:
False
True
False
True
Step-by-step explanation:
The 4th option should be correct because the y-intercept on A is greater than the one in B,
A: y = -1/3x + 0 (usually when the y-intercept ain't appearing it means it's 0).
B: y = -1/3 - 2
As we know 0 is greater than -2 because it's closer to being a positive number, so 0 is not positive or negative; 0 is greater than any negative number but smaller than any positive numer so,
0 > -2.
Therefore the last option is true.

What is the surface area?
Someone please help
Answer:
134 square inches
Step-by-step explanation:
To find surface area, you must find the individual area of each face of the shape. There are 6 faces on every cube or other rectangular prism, so you must perform 3 equations, as every face has an identical face on the opposite side. The formula for regular area is Length (l) times Width (w).
Large sides on front and back: 8x6=48
Slim sides to the right and left: 1x6=6
Slim sides on top and bottom: 8x1=8
Then combine:
48+48+6+6+8+8=134
