Sylvia set a treadmill for 38 minutes, and so far she has run 61% of the minutes. which is the best estimate for the number of minutes sylvia has run so far? 18 minutes 21 minutes 24 minutes 28 minutes

Option C, 24 minutes.

Step-by-step explanation:

Sylvia set a treadmill for 38 minutes,

But she has run only 61% of the time, that she set.

We have to calculate 61% of 38 minutes.

= 61% × 38

× 38

0.61 × 38

= 23.18 minutes

Sylvia ran only 23.18 minutes on treadmill, We have to give the best estimate for the number of minutes so we can say Sylvia ran 24 minutes.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

60: 45 =12: 9 =4: 3 so the answer is 4: 3
