Answer:
#1 It costs $0.73 to run each lightbulb per month
#2 They lost 9.996 pounds per week
#3 They can dive 3.61363636 miles per hour
Step-by-step explanation:
#1 There are 730 hours in a month. Multiplying that by 0.001 gives $0.73.
#2 There are 168 hours in a week. Multiplying that by 0.952 gives 159.936 ounces. 159.936 ounces = 9.996 pounds
#3 One minute equals 60 seconds. 318x60 gives 19,080 feet. 19,080 feet converted gives 3.61363636 miles

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?
=========================================================
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.

a) In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race.
If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?
Answer:
233.53 s
Step-by-step explanation:
The sum of best times for the legs is ...
56.81 +59.22 +57.39 +60.11 = 233.53 . . . seconds
Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.
What's the banana worth?
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.
I hope this helped!!

Several items in a store are on sale. Complete the table with the correct prices.
Answer:
1.$36
2.$35
3.$51
4.$43
Answer:
1.) $35
2.) $36
3.)$51
4.)$43
Step-by-step explanation:
1.)30% of 50 is 15 and you would subtract the 15 from 50 to get your discount.
2.)55% of 80 is 44 and you would subtract 44 from 80 to get your after price.
3.)For this one, I divided the discount price by 3 and multiplied it by 4 to get the original price since 1/4 was taken from it or 25%.
4.) There was only one option left.
