QUESTION :-
Galina-37 [17]

Answer:

  • 92000

Step-by-step explanation:

<u>Given:</u>

  • I = 5% = 0.05
  • t = 2 years
  • Let the sum is x.

<u>Simple interest:</u>

  • SI = x*2*0.05 = 0.1x

<u>Compound interest:</u>

  • CI = x*(1 + 0.05)² - x = 1.1025x - x = 0.1025x

<u>The difference is 230:</u>

  • 0.1025x - 0.1x = 230
  • 0.0025x = 230
  • x = 230/0.0025
  • x = 92000

Ajax is 5 and 1 fourth feet tall. His sister is 3 eighths foot shorter than Ajax How tall is Ajax Sister?
user100 [1]

Answer:

4\frac{3}{4} feet tall

Step-by-step explanation:

Ajax is "5 and 1 fourth feet tall", which can be written as the mixed number 5\frac{1}{4} .

His sister is "3 eighths foot shorter", so she's 3/8 feet shorter than 5 1/4.

So, this is just a subtraction problem:

5\frac{1}{4} -\frac{3}{8}

To solve this, we want to convert 5 1/4 into an improper fraction, which is: \frac{21}{4} . Now, we want to find a common denominator. In this case, that common denominator is 8, so \frac{21}{4} =\frac{42}{8} .

Finally, we subtract 3/8 from 42/8: \frac{42}{8} -\frac{3}{8} =\frac{39}{8} . So, Ajax's sister is 39/8 feet. Converting this into a mixed number, we have: 39/8 = 4\frac{6}{8} =4\frac{3}{4} .

Therefore, Ajax's sister is 4\frac{3}{4} feet tall.

Hope this helps!
