Ok, so lets evaluate this here:
2/3 (x - 6) - y       Let's do the first part: 2/3 (x - 6)
                           If X = 9 then we subtract 6 from 9 and get 3. Then we multiply 
                           3 by 2/3 and get 2.
Then lets do the 2nd part: 2 - y.
So if y = 5/6, we can first convert 2 into an improper fraction in sixths and have 12/6. Then. we just have to do 12/6 - 5/6 and subtract the numerators and end up with 7/6. The final answer is A, hope this helps!

A youth group is setting up camp. Rain is predicted, so the campers decide to build a fly, or rain cover, over their tent. The f
pshichka [43]
The image for this is attached for reference. This problem can be used by the Pythagorean equation.  To make solving convenient, let us see only one part of the tent. Hence, one side is half of the tend width which is 16/2ft. Height is 12 ft. The unknown side is the hypotenuse. The answer is: 
a^{2} + b^{2}  = c^{2}    8^{2} + 12^{2}  = c^{2}   c = 14.4

Why is the number of operators per shift multiplied by approximately 4.5 to obtain the total number of operators required to run
4vir4ik [10]

I believe you meant "why is the number of shifts multiplied by approximately 4.5 to obtain the total number of operators required to run the plant"

Answer and Explanation:

There are 3 shifts per day, 49 weeks per year and 5 shifts per operator per week

To get total number of operators required to run the plant, we multiply number of shifts in a year by number if operators per shift.

49 weeks×5 shifts= 245 shifts per operator per year

365×3 shifts= 1095 shifts per year

1095/245=4.5 operators per shift

total number of operators required to run the plant(per day) = 4.5×3= 13.5 approximately 14

total number of operators required to run the plant(per year) =4.5×1095=4927.5 approximately 4928

Find the Value of X. If your answer is not an integer, express it in simplest radical form.
Gennadij [26K]
For each question we must apply the Pythagorean theorem and clear the value of x.
 question 5 
 x = root (14 ^ 2 + 16 ^ 2)
 x = root (452)
 x = 2raiz (113)
 question 6
 
x = root (8 ^ 2 + 15 ^ 2)
 x = 17
 question 7
 
x = root (12 ^ 2 + 12 ^ 2)
 x = root (2 * (12 ^ 2))
 x = 12raiz (2)
 question 8
 x = root (18 ^ 2 - 9 ^ 2)
 x = root (243)
 x = 9raiz (3)
