Keyanna saved $75 this summer by babysitting. After school, she makes $10 a week babysitting. a) Write an equation for the amount, A, of money that she will have after w weeks.
b) How much will she have after 5 weeks?
c) How many weeks until she has $255?

Answers

Answer 1
Answer: Given:
Savings : $75
Babysitting earnings : $10 a week.

a) A = $75 + $10w

b) A = $75 + $10 * 5 weeks
    A = $75 + $50 
    A = $125

c) A = $75 + $10w
  $255 = $75 + $10w
  $255 - $75 = $10w
  $180 = $10w 
  $180/$10 = w
   18 = w
Keyanna needs to babysit for 18 weeks.

If the subtrahend is 9 and the difference is 8 what is the minuend

Answers

The subtrahend is 9 and the difference is 8 and the minuend is 17

Final answer:

In the subtraction operation, the minuend is the number we are subtracting from. Given the subtrahend (9) and the difference (8), we can find the minuend by rearranging the subtraction formula: Difference + Subtrahend = Minuend. This gives us 8 + 9, so the minuend is 17.

Explanation:

In a subtraction operation, the number that is subtracted is called the subtrahend and the number you are subtracting from is called the minuend. The result of the subtraction is called the difference.

In your question, you're told the subtrahend is 9 and the difference is 8. The formula for subtraction is: Minuend - Subtrahend = Difference. So, to find the minuend, you rearrange the formula to: Difference + Subtrahend = Minuend. Plugging the values in, you get: 8 + 9 = 17. So, the minuend is 17.

Let's plug the given value is in the formula : { V }_( cylinder )=\quad \pi { r }^( 2 )h 

First cylinder : { V }_( cylinder1 )=\quad \pi { 8 }^( 2 )21=\pi \cdot 64\cdot 21=1344\pi \quad { cm }^( 3 )

Second cylinder : { V }_( cylinder2 )=\quad \pi { 11 }^( 2 )45=\pi \cdot 121\cdot 45=5445\pi \quad { cm }^( 3 )

bill wieghs 120 pounds and is gaining ten pounds each month. phil weighs 150 pounds and is gaining 4 pounds each month.how many months, m, will it take for bill to weigh the same as phil

Answers

Answer:

5 months

Step-by-step explanation:

120 + 10m = 150 + 4m

Subtract 4m from 10m on both sides ( 4m cancels out which leaves 120 + 6m=150)

120 + 6m = 150

Subtract 120 from 150 on both sides (120 cancels out which leaves 6m = 30

6m= 30

Divide 30 by 6 on both sides ( 6 cancels out which leaves 30/6

m=5

Bill will weigh the same as Phil in 5 months.

Assuming the weight can is represented by w, the expression for Bill's weight given a certain number of months (n) is:

w = 120 + 10n

For Phil it will be:

w = 150 + 4n

Putting the expressions together will give you:

120 + 10n = w = 150 + 4n

10n - 4n = 150 - 120

6n = 30

n = 30 / 6

n = 5 months

It will take 5 months for Bill to weigh the same as Phil.
