A=1/10, b=1/12, c=1/15 (these are the rates for each worker...)
1.)
2(1/10)+4(1/12)+t/15=1
1/5+1/3+t/15=1
(3+5+t)/15=1
3+5+t=15
8+t=15
t=7
So it would take c 7 hours to finish the job.
2.)
1/40-1/60
(3-2)/120
1/120
The drain rate is 1/60. So you will need to find t when the tank is empty, while starting at 2/3 capacity...
2/3-t/60=0
(40-t)/60=0
40-t=0
t=40
It would take 40 minutes to empty the tank when it is 2/3 full.
Answer:
The numbers would be 89,414 , 89,416, and 89,418
Step-by-step explanation:
In order to find this, start by setting the lowest number as x. Then we can determine that the next two even integers are x + 2 and x + 4. From this we can write the following equation.
2(x) + x + 2 = 268,244
3x + 2 = 268,244
3x = 268,242
x = 89,414
Since the first number is 89,414, we know the next two are 89,416 and 89,418.
I think the answer is a because if logan is 4 times older than dylan and dylan is less than 12 years old then that means that logan is older than dylan. which means that since logan isn’t older than 12 dylan also can’t be older than 12 which cancels out both c and d. it can’t be b because if logan is 4 times older than dylan that would most likely mean dylan is less than 3 so the correct answer (for me i might be wrong) is a
hope this helped
The answer would be 2 to 1 because if you simplify for every one unshaded piece you have 2 shaded pieces
