Answer:

12 Pencils Sharpened

Step-by-step explanation:

Since the sharpener receptacle is emptied out 2 times every day.

Do 24*2 to get 48 pencils sharpened each day.

Now do 48/20 to get how many pencils a single person sharpens each day. Resulting in 2.4 pencils each day for 1 person.

Multiple 2.4 by 5 (Amount of days) to get 12 pencils in 5 days.

Lena [83]

Answer:

The expression to find Carey's hourly rate is: c = 2*a - 2. Carey's hourly rate is $10.

Step-by-step explanation:

Anderson receives 1 more than half of carey's hourly rate. If we call Anderson's rate by "a" and Carey's by "c", we can express this phrase in the following equation:

a = \frac{c}{2} + 1

We want to find the Carey's rate, therefore we need to isolate the "c" variable.

\frac{c}{2} + 1 = a\\\frac{c}{2} = a - 1\\c = 2*a - 2

Since Anderson earns $6, then we can find Carey's rate:

c =  2*6 - 2 = 12 - 2 = 10

What is are the 2 square roots of 121/49
expeople1 [14]
If you are asking what the square roots of 121 are and what the square roots of 49 are it is:

11^2=121 and
7^2=49

if, however you're asking what the square roots of 121 divided by 49, I don't know. (this sign '/' is commonly used as a division sign so I'd just want to clarify).
