Answer:8000
Step-by-step explanation:
Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
The circumference is found by multiplying the radius by pi by 2
And then the arc length would be multiplied by the fraction of the circle..
So using what you wrote is correct, but the answer you got is incorrect.
2x 3.14 x 90 = 565.2 meters
565.2 x 90/360 = 141.3 meters
Answer:
y = 2x + 20
Step-by-step explanation:
Vlad spent 20 minutes on history. Then Vlad spent 2 minutes on each math problem for homework, this is 2x. So in total, he spent 20+2x on homework. Depending on how many problems he did, the total time y can be found. This is the equation 20+2x=y.
If Vlad did 0 math problems then he spent at least 20 minutes on homework from history. This is the constraint .
We also know Vlad can do many math problems but the least amount he did was 0, so the second constraint is .
1. 7
2. 2
3. not sure
4. not sure
5. 1,000
6. 350
7. 40
8. 14
