Answer:
36
Step-by-step explanation:
please mark brainliest
7•8 = 56
Hope this helps!!
Initial number = 36
Final number = 63
Change in number = 63 - 36
= 27
Percentage change = (27/36) * 100
= (3/4) * 100
= 3 * 25
= 75 percent
So the percentage change from 36 to 63 is 75%. I hope the procedure for solving is absolutely clear for you to understand. In future you can attempt such problems by following the procedure shown and you will require no further help from outside. Just be careful about the numerator and the denominator.
Answer:
9 hours, 20 minutes
Step-by-step explanation:
When two ferries work together, they transport a day's cargo in 7 hours
The speed proportion or ratio of larger ferry to smaller ferry is given as 3 : 1
The sum of the ratio = 4 (3 + 1)
This means that it will take the smaller ferry = 7 x 4 hours to work alone = 28 hours, since the larger ferry is faster by 3.
Therefore, when larger ferry works alone, it will take it (7 x 4)/3 = 9.33 hours.
9.33 hours = 9 hours, 20 minutes.
