Answer:
Thanks for the points
Step-by-step explanation:
Solve for x
Please show the steps
The answer is 10
Answer:
x = 10
Step-by-step explanation:
Since ΔCDE ~ ΔQRS, we can find the actual length of x + 8 first before finding the value of x.
Length of x + 8 = [tex]\frac{12}{20}[/tex] × 30
= 18
x + 8 = 18
x = 18 - 8
x = 10
A music group expects to sell a new compact disc (CD) at the rate R(t)=20,000e−0.12t CDs per week, where t denotes the number of weeks since the CD was first released. To the nearest thousand, how many CDs are expected to be sold during the first 12 weeks after the release?
Answer:
4739 CDs
Step-by-step explanation:
Given the function that models the rate at which the disc is sold expressed as;
R(t)=20,000e^−0.12t
t is the number of weeks since the CD was first released
We are to look for the number of CDs that are expected to be sold during the first 12 weeks after the release. To do this, you will simply substitute t = 12 into the modeled function and get R(12) as shown;
R(t)=20,000e^−0.12t
R(12)=20,000e^−0.12(12)
R(12)=20,000e^−1.44
R(12)=20,000(0.2369)
R(12) = 4738.56
Hence the total number of CDs expected to be sold to nearest thousand is 4739 CDs
Answer:
127,000

Here are the instruction plz help asap
Part 1
You will need to measure five different people. Record your measurements on a piece of paper. Using a tape measure or ruler, measure the length (in inches) of a person’s left foot and then measure the length (in inches) of that same person’s forearm (between their wrist and elbow). Refer to the diagrams below. You will have two measurements for each person.
(An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.)
To measure the forearm, measure inside the arm, between the wrist and the elbow.
Part 2
Organize your data and find the rate of change.
Create a table of the measurements for your data. Label the forearm measurements as your input and the foot measurements as your output.
Select two sets of points and find the rate of change for your data.
Describe your results. If you had to express this relation as a verbal statement, how would you describe it?
Part 3
Compare rates of change.
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
What is the rate of change of the equation from Part A?
Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?
Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.
For this option you will submit the details from all three parts. Submit your measurements, the table, and description that you created in Parts 1 and 2. Submit your answers to the questions from Part 3.
Answer:
again please don't just straight up copy it just use it as a base please also i tried my best and don't know if i got it right
Step-by-step explanation:
Part 2
Organize your data and find the rate of change.
I’m sorry i didn’t know how to make a table so i just did this
Person number 1- Left foot is 9 inches Forearm is 8.5 inches
Person number 2- Left foot is 7.5 inches Forearm is 7 inches
Person number 3- Left foot is 11 inches Forearm is 10.5 inches
Person number 4- Left foot: is 10 inches Forearm is 9.5 inches
Person number 5- Left foot is 6 inches Forearm is 5.5 inches
The rate of change equals y=x-0.5
I believe that it's a function because there is a relationship between 2 variables.
Part 3
Compare rates of change.
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
i don’t know how to type all my formulas and work so i'm just going to say the answer i got the rate of change = 0.86x or y=0.86x+3.302
What is the rate of change of the equation from Part A?
For Part A i got y=x-0.5 and that part A has the greater rate of change.
Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?
Well, the values have to be different because there are different rates of change and different linear coefficients; and also each input value will result in a different output value because they all have different parameters as well.
Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.
Yes, it is a function because each input from part A fits well together with the output on the other set, which matches the definition of a function.

Step-by-step explanation:
Sandy has 27 roses, 9 daisies, and 45 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?
We solve the above question using Greatest Common Factor method.
We find the factors of 27, 9 and 45
The greatest common factor is the highest factor common to these 3 number
Hence:
The factors of 9 are: 1, 3, 9
The factors of 27 are: 1, 3, 9, 27
The factors of 45 are: 1, 3, 5, 9, 15, 45
Then the greatest common factor is 9.
Therefore, the greatest number of flowers that could be in a bouquet is 9 flowers
Each bouquet would contain
For 27 roses = 27/9 bouquet = 3 roses
For 9 daisies = 9 daisies/9 bouquet = 1 daisies
For 45 tulips = 45 tulips/9 bouquet = 5 tulips

What do you call the origin, X-axis, and y-axis in the polar coordinate system?
Answer:
coordinate plane?
Step-by-step explanation:
.
Answer:
In polar coordinates the origin is often called the pole. Because we aren't actually moving away from the origin/pole we know that r=0 . However, we can still rotate around the system by any angle we want and so the coordinates of the origin/pole are (0,θ)

Felicia wanted to find the number of boys in the school band if 30% of the 50 students are boys. Is her answer correct? Explain why or why not.
Answer:
Creo que con 15
Step-by-step explanation:
50 -------> 100%
X ---------> 30%
X = (50*30)/100
X= 15 boys
Sample:
No, Felicia’s answer is not correct. She should have divided by 2, not multiplied. 30 divided by 2 is 15. So 15 of the 50 students in the band are boys.
PLEASE HELPPPPP PLEAAASEE
Answer:
11%
Step-by-step explanation:
The full circle graph represents 100% of the given population. All populations are given except for "three or more." Adding all percentages of each population should add up to 100%.
No absences (none): 23%
One absence: 45%
Two absences: 21%
Three more absences: unknown.
Let the variable x represent the unknown population.
23% + 45% + 21% + x = 100%
Combine like terms.
89% + x = 100%
Subtract 89% from both sides.
x = 11%
To put it more simply, subtract all the percentages from 100% to get the percent of the missing population. 100 - 23 - 45 - 21 = 11

how do i graph this? plz help
Step-by-step explanation:
So this is Slope intercept form. Or y = mx+b
M is the slope, b is the y intercept.
Now. We have 5/3 as the slope, or y/x, and -9 and the y intercept.
Start from the point (0,-9) (y intercept)
Go up 5 (In 5/3)
Go to the right 3 (in 5/3)
And graph where that lands.
Answer:
(0,-9) and (3,-4)
Step-by-step explanation:
the first point would go to -9 on the y axis
then the second one would go from that point (0,-9) go up 5 and go to the right 3 getting you the second point of (3,-4)

A band earned $550.00 for playing at a concert. Their manager takes 15% of the money earned for each show and the band is donating 20% of the money earned to charity. How much money is left for the band to split?
Answer:
The amount of the money earned left for the band to split is $357.5
Step-by-step explanation:
The amount the band earned for playing at the concert = $550.00
The percentage of the money earned taken by the manager = 15%
The percentage of the money earned the band is donating to charity = 20%
The amount of the money earned the manager takes = 15/100 × 550 = 82.5
∴ The amount of the money earned the manager takes = $82.5
The amount of the money earned that is donated to charity = 20/100 × 550 = 110
∴ The amount of the money earned that is donated to charity = $110
The amount of the money earned left for the band to split = $550 - $82.5 - $110 = $357.5.
