In order to find the reciprocal of 10 1/2 you have to figure out the improper fraction. the improper fraction for that equation would be 21/2. reciprocal means opposite, so when you reciprocal a fraction, you have to put the numerator on the bottom and the denominator on the top. so, 21/2 is 2/21. 2/21 is the reciprocal for 10 1/2 :))

There are 8 dinner rolls in a package. How many packages will be needed so that 64 people can get 2 dinner rolls?
rodikova [14]
8 per package.

64*2= 128

Now we need to divide 128 by 8 to see how many packages we will need. 

128/8= 16

Now we know that we need 16 packages so that we can feed 64 people 2 dinner rolls.

Final answer: 16 packages

Delicious77 [7]

Answer:

She earned $20 in tips.

Step-by-step explanation:

First, you need to work out how much pay she'd get for 12 hours work:

12 x $11.25 = $135 for 12 hours work

Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:

2/5 of $11.25 = $4.50

Add both these sums together to get her total pay for hours worked:

$135 + $4.50 = $139.50

Subtract that sum from her total pay to find out how much money she earned in tips:

$159.50 - $139.50 = <u>$20</u>

Show work, please someone help me, i'm confused still on this concept.
BigorU [14]
Answer: choice C) -15x^4y

-----------------------------------------

Explanation:

The coefficients are -3 and 5. They are the numbers to the left of the variable terms
Multiply the coefficients to get -3*5 = -15. So -15 is the coefficient in the answer

Multiply the x terms to get x^3 times x = x^(3+1) = x^4. Notice the exponents are being added

Do the same for the y terms as well: y^2 times y^(-1) = y^(2+(-1)) = y^(2-1) = y^1 = y

So we have a final coefficient of -15, the x terms simplify to x^4 and the y terms simplify to just y

Put this all together and we end up with -15x^4y which is what choice C is showing
