2 water taps A B fill a tank in 12 hrs. Tap A takes 10 hrs less than tap B to till tank separately. Find time taken by tap B to
Hatshy [7]

Answer:

11 hours

Step-by-step explanation:

Setting up a system of equations and using the substitution method will give you the number of hours used by each tap.  Let a = time for tap A and b = time for tap B:

a + b = 12  (A and B fill a tank in 12 hours)

a = b - 10 (tap A takes 10 hours less than tap B)

Substitute 'b - 10' for 'a' in the first equation:

b - 10 + b = 12

Combine like terms: 2b - 10 = 12

Add 10 to both sides: 2b - 10 + 10 = 12 + 10 or 2b = 22

Divide by 2: 2b/2 = 22/2

Solve for b: b = 11 hours

Alright, second try. 15 Points to whoever can solve with a half-decent explanation.
sesenic [268]

Answer:

29 cans

Step-by-step explanation:

To solve this problem we must use Heron's formula; A = \sqrt{S(S-a)(S-b)(S-c)}

S = 1/2 the perimeter of the given triangle

a, b, c = the measurements of the three given sides

The first step to solving this question is first finding the perimeter.

P = 65m + 74m + 67m

P = 206m

Now that we have our perimeter, we must divide P by 2 to get S.

S = 206/2

S = 103

Now we plug our numbers into Heron's formula.

A = \sqrt{S(S-a)(S-b)(S-c)}

A = \sqrt{103(103-65)(103-67)(103-74)}

A = \sqrt{103(38)(36)(29)}

A = \sqrt{103(39672)}

A = \sqrt{4086216}

Find the square root of this number.

A ≈ 2021.43909134... m²

If a can of paint covers 70 square meters, then you will need to figure out how many cans you need. This can be done by dividing the overall area of the triangle by the area that a single can of paint can cover.

\frac{2021.43909134...}{70} = 28.8777013049...

We know we can't buy 28.87... of a can (people simply do not sell parts of cans or half-full containers... unless its a bag of lays chips and their 80% air nonsense...) so we must round up to the nearest whole number.

28.87... = 29

Thus we finally have our answer: 29 cans of paint!

Sally rides her bike 164.45 miles in two weeks. She averaged 12.65 miles per hour each time she rode. How many hours did it take
galina1969 [7]

Answer: It took 13 hours by her to ride 164.45 miles.

Step-by-step explanation:

Total distance =  164.45 miles

Average distance traveled = 12.65 miles per hour  (speed)

Time = \dfrac{Distance}{Speed}

Time = \dfrac{164.45}{12.65}=\dfrac{16445}{1265}\\\\=13\text{ hours}

Hence, it took 13 hours by her to ride 164.45 miles.
