2 batches:1/4 which is 25 min.
so 1 batch would be half of that.
So just divide 25 by 2, which would get you 12.5
12 minutes, and 30 seconds.
Hope this helped~
Answer:
(7x + 14)° = 84°
(15x - 4)° = 146°
Step-by-step explanation:
62° + (7x + 14)° = (15x - 4)°
62° +7x + 14 = 15x - 4
15x - 7x = 62 + 14 + 4
8x = 80
x = 10
Therefore, exterior angle (15x - 4)° = 146°
interior angle (7x + 14)° = 84°
Let the number of times she turns the pedal in one mile be x.
Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then

Therefore, she turns the pedal 500 times in one mile.
Answer:
The answer is 121.50
