Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using algerbreaic representations or visual models
Bingel [31]
25% of 15 is the same as 15% of 25
25%=25/100
25% of 15=(25/100)15=(25*15)/100

15%=15/100
15% of 25=(15/100)25=(25*15)/100

Therefore:
25% of 15=15% of 25
because:
(25/100)15=(15/100)25
(25*15)/100=(25*15)/100

Mr. Marcucci received a bonus of $496 from his employer. He has to pay 33% of his bonus to taxes. How much will Mr. Marcucci pay
tiny-mole [99]
Edit: 33% is not \frac{1}{3}, therefore my solution is wrong. The correct answer is 0.33 x 496, which is $163.68

The following is the original solution, which is incorrect. 
33% = \frac{1}{3}. Multiply the bonus of $496 by \frac{1}{3} to get the solution of \frac{496}{3}, or 165 and \frac{1}{3}

Therefore the solution is $165.33

What is the value of x?
Juliette [100K]

Answer:

94

Step-by-step explanation:

The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion to find KY.

\frac{95.2}{168}=\frac{34}{KY}

Cross multiply to solve for KY.

95.2(KY) = 168(34)

95.2KY = 5,712

KY = 60

Add KY to 34 to find x.

60 + 34 = 94.
