Answer:
1 = Given
2 = Addition Property of Equality
3 = Division Property of Equality
Step-by-step explanation:
<u>1 = Given</u>
[] The problem gives us this equation
<u>2 = Addition Property of Equality</u>
[] We add 2x to both sides, which is the addition property of equality
<u>3 = Division Property of Equality</u>
[] We divide both sides of the equation by 6, which is the division property of equality

Answer:

Step-by-step explanation:
Given that,
The area of the base = 13.2 cm²
The height of the pyramid = 13.7 cm
We need to find the volume of this pyramid. The formula can be given by :

Put all the values,

So, the volume of the pyramid is equal to
.
Answer:
51.72 cm.
Step-by-step explanation:
We have been given that a pipe that is open at both ends has a fundamental frequency of 320 Hz when the speed of sound in air is 331 m/s. We are asked to find the length of the pipe.
First of all, we will find the wavelength using following formula.


We know that Hz is equal to
.




Length of the pipe would be half of the wave-length.

Since the length of pipe is in meters, so we will convert it into cm.
1 m = 100 cm

Therefore, the length of the pipe would be 51.72 cm.
0.375 is the answer because there are 3 0's in COLORADO and 8 letter's in total. The fraction part would be 3/8 and in decimals it is 0.375.
.312
Frequency is 24
To find relative frequency (of Pop music) you would take 24 and divide it by the total students you were surveyed.
24/77 = .3116 rounded to hundredths becomes .312
If they are looking for percentage, you take the .312 and multiply by 100 to get 31.12%
