If you would like to solve 7% of what length is 200 ft, you can calculate this using the following steps:
7% of what length is 200 ft
7% * x = 200
7/100 * x = 200 /*100/7
x = 200 * 100 / 7
x = 2857 ft
Result: 7% of 2857 ft is 200 ft.
If 1 to 7 are the chances to win over friend then 6 out of 7 are the chances to lose.
Probably to lose = # of loosing chances/ # of possible outcomes = 6/7 ~ 0.86
She was late 7 times. $42-$10=$32. $32/8 = 4. The first 3 days she was late plus the other 4 times being late that month is 7 days late.
<span>the train cannot exceed a length of 1100 feet
Now, train A = 28 cars at 30 feet each
Therefore, Train A's total length = 28*30 = 840 feet < 1100 feet.
</span>Now, train B = 22 cars at 40 feet each
Therefore, Train B's total length = 22*40 = 880 feet < 1100 feet.
Thus, both the <span>trains meet the requirement. </span>
