Answer:
54
Step-by-step explanation:
First, take the number 200. we can remove 20, because they didn't go to the exams.
Secondly, we have to find 70% of 180. This can be done by doing some math.
Let's do this by using fractions. 70/100 * 180 = 126.
Third, we find the other 30% by doing the same equation.
30/100 * 180 = 54
(This is the part where you thank me, and give your opinions, and maybe "brainliest" answer. :D)
So,
When rounding to the nearest thousand, look at the number in the hundreds place. If it is greater than or equal to 5, round up. If not, round down.
256,035
The hundreds place is less than 5, so we round down.
256,035 --> 256,000
Answer:
Total = 686000 meters for 10 weeks 7 days a week.
Step-by-step explanation:
Let's solve this by doing the increase on just 1 training day per week. Then we can find the grand total for 7 days a week by multiplying by 7
a = 8000
n = 10
d = 400
Sum = (a + L)*n/2
- L = a + (n - 1)*d
- L = 8000 + (10 - 1)*400
- L = 8000 + 9*400
- L = 8000 + 3600
- L = 11600 meters
Sum = (8000 + 11600)*10/2
Sum = 19600 * 10/2
Sum = 98000 meters.
This total represents 1 training day a week.
The total amount is 7 times this figure.
Total = 7 * 98000 = 686 000 meters.
I think you are doing limits so this is what I did
and that's how I factored using the box method because it's easier to track distribution.
