Answer:
20/7 days (just less than 3 days)
Step-by-step explanation:
Recall that (1 job) = (rate)(time), so time = (1 job) / (rate).
Set up and solve the following equation:
1 job
------------------------------- = time required for 2 pumps working together
1 job 1 job
---------- + -------------
4 days 10 days
This comes out to:
1 job
------------------------------------------- = time required
10 job-days 4 job-days
------------------ + -----------------
40 days 40 days
or:
1 job
-------------------- = (40/14) days, or 20/7 days (just less than 3 days)
14 job·days
-----------------
40 days
S = r·α is the formula to find the arc length (s), given the radius (r), and angle measure (α) in radians.
If the angle measure is NOT given in radians you must convert to radians.
s = 8 · 2.6
s = 20.8 in
Hello! I would love to help!
Okay, we know that Raphel has to pay 3,000 dollars in a certain amount of months. Let's let "m" represent the amount of months it will take him.
Now, if we know that he saves 340 dollars a month, we can multiply the unknown amount of months, "m" by 340 to find how many will get 3000.
Here's our equation:
340m = 3000
Alright let's solve for m.
Divide both sides by 340.
340m/340= m
3000/340=8.824
So know we know m= 8.824, or exactly 8.824 months to save 3000 dollars.
However, it is really hard to count 8.824 parts of a month. Let's round it to the nearest whole, nine.
So, that means your answer is 9 months!
Hope this helped! Comment if you have questions!
