Answer: 1 hour 15min
Step-by-step explanation:
When Paul passes the gas station Mary si already 12.5 miles away
X=v t = 50mph 0.25h = 12.5 miles. (15min equals a quarter hour)
From that moment to the meeting point we’ll have only one t (time) and one x (final point) for both cars
For Mary we have
X= Xo + v t= 12.5 miles + 50mph t
For Paul we have
X=v t = 60mph t
As x si the same in both equations
60mph t = 12.5 miles + 50mph t
(60mph - 50mph) t = 12.5miles
10mph t = 12.5miles
t = 12.5miles/10mph
t = 1,25 h
Answer:
21 maybe?
Step-by-step explanation:
if those numbers represent lengths and those lines are the same size, x is 21
thirty-seven point five percent and three per eight
Since you are not allowed to draw a black marble, then you have only 7 ways to draw either a blue or a red marble. The sum of all marbles is 10. So the probability of not drawing a black marble is 7/10 and the probability of drawing a red marble is 2/10 or 1/5.
8 employees exercise at least three times a week
<em><u>Solution:</u></em>
At the office where Mika works 41% of the 19 employees exercise at least three times a week
To find: Number of people who exercise at least three times a week
From given information,
Total employees = 19
Employees exercise at least three times a week = 41 % of total employees
Therefore, we have to evaluate 41 % of 19
Number of people exercise at least three times week = 41 % of 19
Thus approximately 8 employees exercise at least three times a week
