What is the percent of 60 is 15

Mathematics

frutty [35]4 years ago

To find the percent of 15 out of 60, you have to divide fifteen by sixty. 
Then, you multiply your answer by 100. (We do this because 100 percent is a exact amount. 100% of sixty is...well, sixty.)

15 / 60 = 0.25

Now, we can multiply 0.25 by 100:

0.25 * 100 = 25 (basically just moving the decimal two places to the right.)

Next, add a percent sign:

25%, is your answer. 

15 is 25% of 60.

Solve the right triangle shown in the figure.<br> B = 16.9°, b = 30.5
Aloiza [94]

Answer:

A=73.1

a=100.387

c=√ 11007.799769

Step-by-step explanation:

A=180-90+16.9=73.1

Tan(16.9)=30.5/a

=100.387

a^2+b^2=c^2

100.387^2+ 30.5^2=c^2

c=√ 11007.799769

A computer that originally cost $500 is on sale for $350. What is the percent discount?
laiz [17]

Answer:

30%

Step-by-step explanation:

  1. 500 - 350 = 150
  2. Set up a proportion: \frac{150}{500} = \frac{x}{100}  
  3. Cross multiply, then divide: 150 × 100 = 15000, 15000 ÷ 500 = 30
  4. Write the completed fraction: \frac{30}{100}  
  5. \frac{30}{100} = 30%

I hope this helps!
