Answer:
The percentage ≅ 48.4%
Step-by-step explanation:
The volume of water left in container A = 2197π - 1134π = 1063π feet³
* To find the percentage of the water that is full after pumping
is complete, divide the volume of water left in container A
by the original volume of the container multiplied by 100
∴ The percentage = (1063π/2197π) × 100 = 48.3841 ≅ 48.4%
A right triangle has sides of length 3, 4, and x. Find x if it is the hypotenuse.
HELP ME PLEASE
Answer:
5
Step-by-step explanation:
The rules for the hypotenuse is side a^2+side b^2=hypotenuse^2
a=3
b=4
3^2=9
4^2=16
9+16=25
5^2=25, so 5 is the hypotenuse.

The tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.
Cara's Flower Arrangements
White 3 6 9 12 15
Yellow 5 10 15 20 25
Hector's Flower Arrangements
White 4 8 12 16 20
Yellow 6 10 14 18 22
Part A
Are the numbers of white and yellow flowers in Cara's arrangements proportional?
Which equation relates the number of white flowers, w, to the number of yellow flowers, y?
A. Yes; y=35w
B. Yes; y=53w
C. No; y=3w+5w
D. No; y=5+3w
Part B
Are the numbers of white and yellow flowers in Hector's arrangements proportional?
Write an equation to relate the number of white flowers, h, to the number of yellow flowers, e.
A. Yes; e=32h
B. Yes; e=23h
C. No; e=h+2
D. No; e=h−2
Answer:
Step-by-step explanation:
Part A
Yes, there is a proportional relationship in Cara's. For every 5 yellow flowers, there are 3 white flowers. 5:3. I didn't see an equation that would work for the equation in the question. The equation I found on my own would be 5w/3 = y
Part B
There is no proportional relationship in Hector's. The equation would be e=h-2.

Do the values in the table represent a proportional relationship?
x 1 2 3 4
y 2.5 5 7.5 10
Select from the drop-down menu to correctly complete the statement.
All of the y-values a constant multiple of the corresponding x-values, so the relationship
Answer:
yes every values are increasing constantly by 2.5
Answer:
Step-by-step explanation:
Note that for each unit increase in x, y increases by 2.5. The constant of proportionality is therefore 2.5:
y = 2.5x
All of the y-values are a constant multiple of the corresponding x-values, so the relationship is a proportional one.

Create a scatterplot displaying the data in the table. Be sure to include a linear trend line. (2 points)
Can you show more information please?
Answer:
Using technology, the linear regression equation which models the data of the relationship between the number of customers served and tips received is :
y = 1.87x + 3.66
predicted amount of tip for 100 customers = $191
The predicted amount of tips received of 100 customers are served :
y = 1.87x + 3.66
x = 100 ; substitute x = 100 into the equation
y = 1.87(100) + 3.66
y = 187 + 3.66
y = 190.66
Hence, about $191 would be received on tips if 100 customers are recorded.
Using a regression calculator to make prediction from a data table :
Enter the x and y axis data into the appropriate column so that the calculator can display the actual data model. Hence, given a certain value of either variable, the predicted value of the required variable can be calculated from the model.

Mr. Bloss made 36 out of 48 free throws while practicing for basketball. What percent of his free throws did he make?
Answer:
75%
Step-by-step explanation:
We can see that our fraction is 75/100, which means that 36/48 as a percentage is 75%.
Answer:
75%
Step-by-step explanation:
To find the percentage of successes, simply divide the number of successes by the number of tries. Hence 36/48=.75. Then, multiply by 100% to get the percentage value --> .75x100%=75%

Jaylen's beta fish tank holds 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. What is the flow rate of the water in gallons per minute? (label your answer gpm) pls dont delete or post links Ty worth 29 points and brainlyiest
I had this same question! ill tell you what i got.
Answer:
12/5
Step-by-step explanation:
His fish tank is 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. So you need to find out how many gallons you can pour in 1 minute. You can eliminate A (5/12) because he is filling more than 1 gallon per minute. You can divide 4.5 (4 1/2) by 1.875 (1 7/8). You get 2.4. Convert it back to a fraction, and you get 2 4/10. Simplify the fraction 2/5. Now convert it to an improper fraction. 12/5.

Giovanni can read 210 words per minute. If there are approximately 540 words on a page, about how many pages can he read in 3 hours? Round your answer to the nearest whole number.
462 pages
122 pages
233 pages
70 pages
She can read 70 pages in 3 hours.
What is proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We are Given:
Giovanni can read 210 words per minute and, books contain 540 pages
So, she can read the portion of book
=210/540
= 21/54 per minutes
= 21/54 x 60
= 23.3 pages in one hour
and in 3 hours she can read
= 23.3 x 3
= 70 pages in 3 hours
