Answer:
so it equation a= 0.2
Step-by-step explanation:
Answer:
The first one (a = 0.2 x 150). And a = 30
Step-by-step explanation:
To find a percentage of a number, you multiply it by 0.10 for 10%, 0.20 for 20%, and so on. Since a is the unknown number, that makes the first option correct. Now, we multiply .2 and 150 to get 30. That is the answer to the second part.

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.
Answers
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.

What do you call the origin, X-axis, and y-axis in the polar coordinate system?
Answers
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)

Answers
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

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

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 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?
Answers
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)
