Stan's cookie recipe makes 24 cookies and calls for exactly 384 sprinkles. He is wondering how many sprinkles (p)eft parenthesis, p, right parenthesis he will need to make 60 cookies. He assumes each cookie will have the same number of sprinkles.
How many sprinkles does Stan need to make 60 cookies?
Answers
Answer:
960 sprinkles
Step-by-step explanation:
x = sprinkles
For this problem we will create a ratio
[tex]\frac{24}{384} :\frac{60}{x}[/tex]
24x=384*60
24x=23,040
x=23,040/24

Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.
The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
2. What is the MAD for company C's data? Show your work.
3. Which company had the greatest mean number of deliveries?
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Answers
Answer:
The means differ by 4 times the MAD.
Step-by-step explanation:
I may be missing something, but this is how I interpret it.
The mean number of deliveries for company A is 6, and the mean for company B is 14. Lastly, the mean absolute deviation (MAD) for both companies is 2.
[tex]14-6=8\\8\div2=4[/tex]
The means differ by 8, and that is 4 times the MAD, so the means differ by 4 times the MAD.

Twice the sum of a number and 11 is 34.
What is the number?
Answers
Answer:
Twice the sum of 11.5 and 11 is 34.
Step-by-step explanation:
Twice the sum of a number and 11 is 34.
This implies the equation:
2x+11=34 -> Solve for X.
34-11=23.
23/2=11.5
X=11.5

What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Twice the sum of a number and 11 is 34.
Assuming the number to be 'n', so the statement can be numerically expressed as,
2(n + 11) = 34.
2n + 22 = 34.

of the 400 of the sixth graders at school, 60% want more library books. how many students want library books?
Answers
Answer:
240
Step-by-step explanation:
it’s simple math!
Since 60% of the 400 kids want more Library books, all you need to do is:
100% - 60% = 40%
find 40% of 400:
400 x 0.4 = 160
then subtract 160 from 400 to get 60%:
400 - 160 = 240
therefore 240 is your answer! :)

Step-by-step explanation:
Picture 1:
[tex]2x+x-3=90\\3x-3=90\\3x=93\\x=31[/tex]
First, add the 2x and x together for 3x
Then add 3 to both sides of the equation
Finally, divide each side by 3.
Picture 2:
[tex]7x+x+20=180\\8x+20=180\\8x=160\\x=20[/tex]
First, add 7x and x together for 8x
Then, minus 20 from both sides of the equation
Finally, divide each side by 8.
Step-by-step explanation:
First picture
We can make an equation with this
2x+x-3=90
3x=93
x=31 degrees
Second picture
We can make and equation
7x+x+20=180

Emily has fixed monthly expenses that are taken directly out of her bank account.
Emily wants to know how much money she must deposit in her account each month to cover these expenses.
How can Emily use an additive inverse to find this amount?
Answers
Answer:
Emily must deposit each month.
Step-by-step explanation:
As you know that Additive inverse of any number
A = - A, For example additive inverse of 2 is - 2
or additive inverse of (-2) is 2.
Now, According to the question given
Emily has fixed monthly expenses that are taken directly out of her bank account.
As she wants to know, how much money she must deposit in her account each month to cover these expenses.
So, Expenses are Additive inverse of Deposit or Deposit are additive inverse of Expenses.
Out of the given Options Option D which is, Emily can add (-48) + (-12) + (-44) to find her total expenses. The additive inverse of this number is the amount Emily must deposit each month. is correct
