Answer:
1.5 min
100 rotations
Step-by-step explanation:
to find 300 rotations time duration use the half-minute,
to find half of a minute divide the amount in one minute (200) by 2
200/2 = 100
then mutiply the 100 times 3 to find the time
100 * 3 = 300
therefore 30 sec (100 rot.) and 3 (3 times)
30 * 3 = 90
90 seconds minus 60 (one minute) is 30
so then it is equal to 1.5 minutes aka 1 min. 30 sec.
How long does it take to complete 300 rotations? 1.5 minutes (1 min. 30 sec.)
How many times does it rotate in a half minute? 100 rotations
hope this helps:)
X = {0, 2, 4, 6, 8}.
=> f(x) = 2x - 1
x f(x) = 2x - 1
0 2*0 - 1 = - 1
2 2*2 - 1 = 3
4 2*4 - 1 = 7
6 2*6 - 1 = 11
8 2*8 - 1 = 15
Answer: {-1, 3, 7, 11, 15}

Answer:
33
Step-by-step explanation:
Add 165 and 80 to get 245. 80 times 3 = 240.
So 80 is around 1/3 of 240. In other words it is around 33%
The answer is B. To find the Circumference (what you're looking for) you use 2×pi×radius. Which is 2×pi×7. In terms of pi that's just 2×7, which equals 14. So that means your answer is 14pi.
