Answer:
9 boxes were packed. 10 brownies were left over.
Step-by-step explanation:
127 ÷ 13 = 9 R10
13 x 9 = 10 x 9 + 3 x 9 = 90 + 27 = 117
127 - 117 = 10
The required rate of water leaking is 0.2 gallons of water per minute.
Given that,
A large container holds 5 gallons of water. it begins leaking at a constant rate. After 10 minutes the container has 3 gallons of water left. at what rate is the water leaking is to be determined.
The rate of change is defined as the change in value with the rest of the time is called rate of change.
Here,
Total volume = 5 gallons
Volume left after 10 min = 3 gallons
Rate = [total volume - volume left] / 10
rate = 5 - 3 / 10
Rate = 2 / 10
Rate = 0.2
Thus, the required rate of water leaking is 0.2 gallons of water per minute.

Answer:
The answer is 90 winners.
Step-by-step explanation:
Well, we are given three days. The first day has a rate of 13% winning. The second day has a rate of 13% as well. And the third day has a rate of 11%. You can find this simply by dividing the amount of winners by amount of participants. Now, we must find the mean, or average, of these statistics. We will get 12% as the average rate of winners. How did we get this? By simply adding all three (13+13+11) then dividing by three (37/3), which gives us 12% if we round to a whole number. Now, we can take this number and get 12% of 750. How do we do this? Well, 12% is equal to 0.12. So we will multiply 0.12 by 750. This will give us 90. And there you have your answer.
Alternatively, you could add up the total amount of contestants from the three days. You should end up with 1000. Then add up the total amount of winners from the three days. You should get 120. Divide both of these by 4. The winners will now be 40, and the total contestants will be 250. Now multiply both by 3. The amount of contestants will be 750, and the amount of winners will be 90. This way is a bit easier, but does not always work. Do what is best for you!

Answer: There are 30 1-meter pieces of ribbon he can cut.
Step-by-step explanation:
Since we have given that
Number of pieces of ribbon = 3
Length of each ribbon = 1 decameter
So, we know that
So, Total length of 3 pieces of ribbon is given by
So, Number of 1- meter pieces of ribbon he can cut is given by
