Number of bikers: b
miles ridden by each biker: 50
number of miles ridden by the team: 50b
Condition: 50b ≥ 560
=> b ≥ 560 / 50
=> b ≥ 11,2
Given that b refers no number of persons it has to b an integer and b has to be at least 12
=> b ≥ 12.
If there would be 11 bikers the team only could complete 11*50 = 550 miles, so they cannot complete the required 560 miles.
Answer: b ≥ 12
Answer:
5.3
Step-by-step explanation:
Use Pyth Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 28
Sq root of 28 = 5.3
This is the answer with the correct work.
If you want to easily find the solution you can use your calculator.
Just divide 77 by 110 and see the result.
77/110 = 0.7 = 7/10 = 70/100 = 70%
100% - 70% = 30%
Explanation
110*x=77
x=77/110, but the answer is not a percent
So 77/110 = ?/100 => ?=77*100/110=70 => 70%
But since 70% does not represent a percentage decreasement, we need to subtract it from the 100%
100% - 70% = 30%
