Find each number. Round to the nearest tenth if necessary
Pavel [41]

Answer:

  1. 96
  2. 6.9
  3. 25%
  4. 8%
  5. 79
  6. 33.8

Step-by-step explanation:

Here is the complete question: Find each number. Round to the nearest tenth if necessary.

  1. 80% of 120.
  2. 115% of 6
  3. What percent of 128 is 32?
  4. 3 is what percent of 36?
  5. 23.7 is 30% of what number?
  6. 71/2% of what is 12?

1) 80% of 120

= \frac{80}{100} \times 120= 8\times 12

= 96

∴ 80% of 120= 96

2) 115\%\ of\ 6

=\frac{115}{100}\times 6= 1.15\times 6

∴ 115\%\ of\ 6 = 6.9

3) What percent of 128 is 32?

= \frac{32}{128} \times 100

= 25\%

4) 3 is what percent of 36?

= \frac{3}{36} \times 100

= 8\%

5) 23.7 is 30% of what number?

Let the number be "x".

⇒ \frac{30}{100} \times x= 23.7

Cross multiplying

⇒ x= \frac{23.7\times 100}{30}

∴ x= 79.

6) 71/2% of what is 12?

Lets assume the required number be "x".

⇒ \frac{71}{2} \times 100\times x= 12

cross multiplying both side.

⇒x= 33.8

∴ 71/2% of 33.8 is 12

What is the frequency of the graph of y = 1/3 sin(2x)?
vovangra [49]

Given:

The sine function is:

y=\dfrac{1}{3}\sin (2x)

To find:

The frequency of the graph of given function.

Solution:

If a sine function is defined as:

y=A\sin(Bx+C)+D

Then, the frequency of the sine function is:

f=\dfrac{B}{2\pi}

We have,

y=\dfrac{1}{3}\sin (2x)

Here, B=2. So, the frequency of the given function is:

f=\dfrac{2}{2\pi}

f=\dfrac{1}{\pi}

Therefore, the correct option is D.
