Answer:
Gregory will catch up Efren after 26 minutes 40 seconds.
Explanation:
Distance traveled = Speed x Time
Speed of Efren = 4 mi/h
Speed of Gregory = 8.5 mi/h
Let the time of catch up be t hours.
Time of journey of Efren before catch up = (t+0.5)hours, since he starts before half hour.
Distance traveled by Efren = 4 x (t+0.5) miles
Time of journey of Gregory before catch up = t hours.
Distance traveled by Gregory = 8.5 x t miles
If they catch up the distance traveled by them is same, so equating both distances.
4 x (t+0.5) = 8.5 x t
4.5t = 2
t = 0.44 hours =26.67 minutes = 26 minutes 40 seconds.
So Gregory will catch up Efren after 26 minutes 40 seconds.
7 out of 24 is made by other companies because you need to find a common denominator for all of the numbers which is 24. 1/3 times 8 is 8/24, 1/4 times 6 is 6/24 and 1/8 times 3 is 3/24. Then add all of those fractions and you get 17 then subtract 24 by 17 to get 7 out of 24 as your fraction. Hope this helps!
Answer:
190 Jeans
Step-by-step explanation:
The daily production cost of the jeans manufacturer is given as:
To determine the number of Jeans,x that should be produced daily to minimize cost, C. We take the derivative of C and solve for its critical points.
Therefore, to minimize daily cost, 190 Jeans is the number of jeans that should be produced daily.

Answer:
0.254
Step-by-step explanation:
Table A-6 will be shown below for reference. Since none of the answer choices contain the critical value for 61, we can just round that number to 60. We will see that the critical value is 0.254. If you're having trouble reading the table below, look at the columns to find the corresponding significance level you are working with then find the sample value.
Best of Luck!
