Step-by-step explanation:
1. Divide it like any other problem
- 24 goes into 85, 3 times with 13 left over
- Bring down the 9 and 24 goes into 139, 5 times with 19 left over
- Then bring down the 5 and 24 goes inside 195, 8 times with 3 left over
So your remainder would be 3

Answer:
C Yes, 75+ 2.5*60 = 225
Step-by-step explanation:
The charges for the electrician
1st hour = 75
Additional hours 60
We have 3 1/2 hours of labor
The first hour is 75 dollars
3 1/2 - 1 = 2 1/2
There will be 2 1/2 hours at the 60 dollar rate
75 + 60 * 2.5 =
75 + 150
225
What you have to do to be able to find the answer is $672 divided be $12. That should give you how many cars the soccer team washed.
Step-by-step explanation:
Day 1: 1200g / 2¹ = 600g
Day 2: 1200g / 2² = 300g
Day 3: 1200g / 2³ = 150g
The pattern is the amount of radioactive substance on day n is 1200 / (2^n).
Therefore, we have to find n where 2^n > 1200.
The first such n is 11 (2¹¹ = 2048).
Hence, there will be less than 1 gram on day 11.
