Help questions 1, 3, 4 and 8 please? It’s due In 30 mins

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.

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.

Answer:

11.9

Step-by-step explanation:

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)

Answer:

10n-20p+20

Step-by-step explanation:

10(n-2p+2)

n(10)-2p(10)+2(10)

10n-20p+20

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

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

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)

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

Step-by-step explanation:

you take the integral from 0 to 12 of R(t)

Answer:

Step-by-step explanation:

Like Terms: terms that have the same variable raised to the same power. So like 5x plus 5x plus 5. 5x and 5x are like terms.

I'm going to assume you mean Constant instead of contestant so

Constant: Terms without variables

Example: 5x+2x+7

5x and 2x are like terms

7 is a Constant

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers.

Each bouquet would contain: 3 roses, 1 daise and 5 tulips

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

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.

Answer: -12/5

Step-by-step explanation: 4/5/3 = -4/5 *3 then multiply the numbers 5 * 3 = 15  =-4/15
