Area of circle= 153.93804
(38.485/153.93804)*360=90.00114592
so about 90 degrees or 10.99557429
Hope this helps and feel free to leave a rate, thanks and brainliest (it would really help me get to virtuoso I would appreciate it a lot) ;)
Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute.
he usually plans to stop and rest for about 5 minutes.
m represents the total minutes.
12 calories per minute.
for m minutes the calories burn is 12m
He stop and rest for about 5 minutes. so we need to subtract 5 from total minutes
So expression becomes 12(m-5)
He wants to burn 540 calories. So we set the calories = 540
The equation becomes ,
12(m-5) = 540
Now we solve for m , total number of minutes
12(m-5) = 540(divide by 12 on both sides)
m - 5 = 45
m = 50 ( add 5 on both sides)
Anzelm should plan to be out jogging for 50 minutes
The expression that she can use is 1/6 x 1/5
I hope this can help :)
Answer:
Step-by-step explanation:
