The time when the two trains reach each other is 1.25 hours
The trains are 68.75 away from the city when they reach each other.
You need to find out if 57 can be divided evenly by a number other than 1 and 57.
57 is odd, so it is not divisible by 2.
The digits of 57 are 5 and 7. Add 5 + 7 to get 12. Since 12 is divisible by 3 (12/3 = 4), then 57 is also divisible by 3.
57/3 = 19
19 is a prime number, so the only factors of 57 are 1, 3, 19, 57.
57 rows can be divided into 19 sections of 3 rows each or 3 sections of 19 rows each.
Answer:
The ticket increased 57% of its original price
The baggage price was 44.5 increased 0.11% and then became 50
Step-by-step explanation:
So if the amount was 200 and now is 350, we should use division.
200 ÷ 350 = 0.5714285714285714 which you can round to 0.57 or as many digits as the question asked for. In thise case I will use 0.57
0.57 converted to percentage is 57%
About the second question
now you know the amount after increase and the percentage. So all you have to do is reverse.
11% = 0.11
0.11 ✕ 50 = 5.5
this means the price increased 5.5
50 - 5.5 = 44.5
Answer:
863.5 ft³
Step-by-step explanation:
Given that :
Diameter, d = 10 ft
Height, h = 11 feets
Radius of tank, r = d/ 2 = 10ft / 2 = 5 ft
The volume of a cylinder is calculated using the relation :
Volume = πr²h
Volume = 3.14 * 5^2 * 11
Volume = 3.14 * 25 * 11
Volume = 863.5ft³
