Answer:
The time required to finish the work by both candy and Tim working together = 36.83 minute
Step-by-step explanation:
Time taken by the candy to finish the work = 85 min
Time taken by the Tim to finish the work = 65 min
Thus the time taken by both to finish the work =
Put the values of and we get ,
=
=
= 36.83 minute
Thus the time required to finish the work by both candy and Tim working together = 36.83 minute
Answer:
8 and 14
Step-by-step explanation:
let the 2 numbers be x and y with x > y
We can model the situation using the following 2 equations
x + y = 22 → (1)
3x - y = 34 → (2)
adding the equations term by term will eliminate the term in y
(x + 3x) + (y - y) = (22 + 34)
4x = 56 ( divide both sides by 4 )
x = 14
substitute x = 14 into (1)
14 + y = 22 ⇒ y = 22 - 14 = 8
Answer of the question: 5 feet 6 inches.
Step By Step explanations: —
- In the present age of a child is now = 2 yrs
- Height in the 2 yrs of a child is = 34 inches
- So, At adult her's height will be doubled = 34 × 2 = 68 inches.
- We know that, 1 foot is = 12 inches.
- So, In 68 inches the height in foot ( or in feets.) will be = 68 ÷ 12 = 5.66 feet
- That's roughly according to the 5 feet and 6 inches in the height.
Answer:
9 days
Step-by-step explanation:
Let x = days taken by C to do it alone
In one day, A can do: 1/12 (part of the whole work)
In one day, B can do: 1/18 (part of the whole work)
In one day, C can do: 1/x (part of the whole work)
In one day,together A, B and C can do: 1/4 (part of the whole work)
we have this equation:
1/x + 1/12 + 1/18 = 1/4
--> 1/x = 1/4 - 1/12 - 1/18 = 1/9
--> x = 9 (days)
