Answer:
V = 160mph
Step-by-step explanation:
We need to start from the formula of speed: V=d/t
We have two travels, with and against the wind, both done in the same time.
Clearing t from the formula, we will have: t=d/V2
450miles/V-35mph (speed of the wind is subtracted)
702miles/V+35mph (speed of the wind is subtracted)
Now, we find V:
450miles/V-35mph = 702miles/V+35
450*V+35 = 702*V-35
450V+15,750 = 702V-24,570
702V-450V = 15,750 + 24,570
252V = 40,320
V = 40,320/252
V = 160mph

Determine the probability of drawing red and green without replacement
This is calculated as follows:



We used Total - 1 because it's a probability without replacement:




<em>Hence, the required probability is 1/11</em>
Answer:
The battery was 19 percent when the charging began.
It took 32.4 minutes for the battery to be fully charged.
Step-by-step explanation:
Number of ones = 60
Number of twos = 62
Number of threes = 59
Number of fours = 64
Number of fives = 63
Number of sixes = 75
Total even outcomes = total number of two, four and sixes = 62 + 64 + 75 = 201
Total outcomes = 60+62+59+64+63+75= 383
Probability if rolling an even number = 201/383
percentage= 201/383 × 100 = 52.48% ~ 52.5%
Answer:
35.4
Step-by-step explanation:
divide 72.8 by 6.5 to get the other two sides. Then you will have all four sides. From there you can add all four sides. 6.5 + 6.5 + 11.2 + 11.2 = 35.4. Hope that helps!
