Converting from one units to another set of units, a conversion factor is needed. For this problem, the conversion factor would be 1 mile = 1610 m. We convert the value of <span>speed</span> of light from meters/second to miles/hour as follows:
3 x 10^8 m/s (1 mile / 1610 m) ( 60 s / 1 min ) ( 60 min / 1 hr ) = 6.71 x 10^8 miles / hr
Using the probability (conditional) formula, where P is equals to the number of favorable outcomes over the total number of outcomes. Calculating using five and the thirty percent, 1.5 is the answer. But that cannot be the answer.
So we look for the probability using this formula derived from the original, (total outcomes) x (percentage) = (favorable outcomes), 5x=2. That gives us the answer of 0.4 or 40%.
Answer:
B 39.75
Step-by-step explanation:
7.5x5.3=?
84 = x% * 600
84 = x/100 * 600
84 = x * 6
6x = 84
Divide 6 on both sides.
x = 84/6
x = 14
14 percent<span> of 400 is 8.</span>
1km is 1000 m
1000m+125m-375m=750m
