Triplets, Justin, Jason, and Jacob are working on a school project. Justin can complete the project by himself in 6 hours, Jason can complete the project by himself in 9 hours, and Jacob can complete the project by himself in 8 hours. How long would it take the triplets to complete the project if they work together?
Answers
=========================================================
Explanation:
Justin can do the full project by himself in 6 hours. This means his rate is 1/6 of a project per hour. In other words, in one hour, he gets 1/6 of the project done.
Jason can do the full project in 9 hours, so his rate is 1/9 of a project per hour, if he works alone.
Jacob's rate is 1/8 of a project per hour since he can get the job done in 8 hours if he works alone.
-----------
So we have these unit rates
Justin's rate = 1/6Jason's rate = 1/9Jacob's rate = 1/8The units for each rate is projects per hour.
The total rate is
1/6 + 1/9 + 1/8
12/72 + 8/72 + 9/72
(12+8+9)/72
29/27
If the three brothers work together, and no person slows down another, then the rate at which they work together is 29/72 projects per hour. In short, they get 29/72 of the project done in 1 hour.
Let x be the number of hours needed to get the project done if they work together. Multiplying this time value with the rate leads to the amount of the project done. We want the result to be 1 to indicate a full project is complete.
(rate)*(time) = amount done
(rate)*(time) = 1 full project
(29/72)*(x) = 1
x = 1*(72/29)
x = 72/29
x = 2.48275862068966
x = 2.483
It'll take about 2.483 hours to get the job done if they work together. Again this assumes that they don't get in each others way to slow each other down.

Answers
Answer:
B ( 92 degrees)
Step-by-step explanation:
1. Find y
In order to find z, we need to find y.
All triangles add up to 180 degrees, so y would be
180 - (48 + 44) = 88
y is 88 degrees
2. Find z
So now we know y is 88, we can find z
The circle of all angles of y and z = 360 ( because full angle)
so our equation is:
(88 + z)2 = 360
Divide by 2
88 + z = 180
z = 92

Answers
Answer:
5!
Step-by-step explanation:
Looking at the first one, you have three watermelons. 36/3 is 12, so one watermelon is worth 12!
With the second one, you subtract 12 from 28 to get 16. Since there are two (peaches?), you divide 16 by two to get the peaches worth, which is 8.
That leaves you with the last one. I used the simple "8 - __ = 3", which got me the answer, 5.
