Answer:

144

Step-by-step explanation:

Susan can pick 4 pounds of coffee beans in an hour.  Tom can pick 2 pounds of coffee beans in an hour.  Together, they can pick 6 pounds of coffee an hour.

4 + 2 = 6

There are 24 hours in a day.  Multiply the time by the amount that can be picked to find the answer.

24 × 6 = 144

Together, the maximum number of pounds of coffee beans the can pick in a day is 144 pounds.

Which is a good comparison of the estimated sum and the actual sum of 7 9/12 + 2 11/12?
natta225 [31]
7 9/12 = 7.75
2 11/12 = 2.917

So we can round both of these up.

7.75 rounds to 8
2.917 rounds to 3

8 + 3 = 11

So the estimated sum is 11.

7 9/12 + 2 11/12 = 10 2/3

So the actual sum is 10 2/3.

The estimated sum is a pretty good estimate to the original number.

Carl collects coins compulsively, but he only likes quarters and dimes. Carl currently has 125 coins for a total of $26.00. How
faust18 [17]

We need to find the two equations that represents the total amount of coins Carl has that makes $26.00 and the number of quarters and dimes.

Carl has 35 dimes and 90 quarters. The equations are 0.1x+0.25y=26 and x+y=125.

Let the number of dimes be x

Let the number of quarters be y

The total number of coins is 125

So, the first equation will be

x+y=125

The value of the coins is $26. So,

0.1x+0.25y=26

Let us solve the equations

x=125-y

0.1\times (125-y)+0.25y=26\\\Rightarrow 12.5-0.1y+0.25y=26\\\Rightarrow 0.15y=13.5\\\Rightarrow y=\dfrac{13.5}{0.15}\\\Rightarrow y=90

x+y=125\\\Rightarrow x=125-90\\\Rightarrow x=35

The number of dimes is 35 and the number of quarters is 90.
