First make improper fractions: —> 13/3 divided by 7/3
Then multiply by the reciprocal: —> 13/3 times 3/7
The threes will cancel making the answer 13/7 or 1 6/7

Here is you're answer:

In order to solve this equation you need to change the mixed numbers into improper fractions then use KCF.

  • Turn into improper fractions:
  • 4\frac{1}{3} = \frac{13}{3}
  • 2\frac{1}{3} = \frac{7}{3}
  • \frac{13}{3} \div \frac{7}{3}
  • Apply KCF:
  • \frac{13}{3} \times \frac{3}{7}
  • Solve:
  • \frac{13}{3} \times \frac{3}{7} = \frac{39}{21}
  • Simplify:
  • \frac{39}{21} \div 3 = \frac{13}{7}
  • = \frac{13}{7}
  • Changed to mixed number:
  • \frac{13}{7} = 1\frac{6}{7}
  • = 1\frac{6}{7}

Therefore you're answer is"1 6/7."

Hope this helps!

Sam invests $800 at 6%/a compounded annually for 5 years. What is the total interest<br> earned?
s2008m [1.1K]
<h3>Answer:    270.58 dollars</h3>

======================================================

Work Shown:

  • A = account value after t years
  • P = principal or amount deposited = 800
  • r = interest rate in decimal form = 0.06
  • n = number of times we compound per year = 1
  • t = number of years = 5

So,

A = P*(1+r/n)^(n*t)

A = 800*(1+0.06/1)^(1*5)

A = 1070.58046208

A = 1070.58

After five years, the account will have $1,070.58 in it.

The amount of interest earned is A-P = 1070.58 - 800 = 270.58 dollars.

A firefighter determines that 350 feet of hose is needed to reach a particular building. If the hoses are 60 feet in length, wha
Nady [450]

Answer:

  6 lengths

Step-by-step explanation:

You essentially want the smallest integer solution to ...

  60x ≥ 350

  x ≥ 350/60

  x ≥ 5 5/6

The smallest integer solution to this is x = 6.

The minimum number of lengths of hose needed is 6.

_____

Informally, you know that dividing the required total length by the length of one hose will tell you the number of required hoses. You also know the ratio 350/60 is equivalent to 35/6 and that this will be between 5 and 6. (5·6 = 30; 6·6 = 36) The next higher integer value will be 6.
