What is the volume of the pyramid
Marianna [84]

For this case we have by definition, that the volume of a square base pyramid is given by:

V = \frac {1} {3} * L ^ 2 * h

Where:

L: It's the side of the base (square side)

h: It's the height of the pyramid

Substituting:

L = 6 \ ft\\h = 10 \ ft

V = \frac {1} {3} * (6) ^ 2 * 10\\V = \frac {1} {3} * 36 * 10\\V = 120 \ ft ^ 3

Answer:

V = 120 \ ft ^ 3

Case study
stepladder [879]

Given:

The data set is

21, 16, 30, 15, 16, 18, 10, 24, 26, 20, 19, 24, 24, 25, 23

10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30

To find:

The range, average and median for the given data set.

Solution:

Arrange the data set in ascending order.

10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30

(1)

Range = Maximum value - Minimum value

           = 30 - 10

           = 20

Therefore, the range of the given data set is 20. All the options are incorrect.

(2)

Average=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}

Average=\dfrac{311}{15}

Average\approx 20.73

Therefore, the average score is about 20.73. All the options are incorrect.

(3)

Number of observations = 15, which is odd.

Median=\dfrac{n+1}{2}\text{th term}

Median=\dfrac{15+1}{2}\text{th term}

Median=\dfrac{16}{2}\text{th term}

Median=8\text{th term}

In the arranged data set 8th term is 21.

Median=21

Therefore, the correct option is b.

The speed of radio waves can be approximated to be 299,790,000 meters per second. The wavelength of a particular radio station’s
azamat

Answer:

f = \frac{299790000 \frac{m}{s}}{3.03 m}= 9890594.06 Hz

And if we convert to megahertz we got:

9890594.06 Hz *\frac{1MHz}{10^6 Hz}= 98.9 MHz

Step-by-step explanation:

For any mechanical wave we have the following general relationship:

v = \lambda f

where:

v represent the speed of the wave = 299790000 m/s

\lambda = 3.03m represent the wavelength for the radio station

f represent the frequency of interest

If we solve for the frequency we got:

f = \frac{v}{\lambda}

And replacing the values we got:

f = \frac{299790000 \frac{m}{s}}{3.03 m}= 9890594.06 Hz

And if we convert to megahertz we got:

9890594.06 Hz *\frac{1MHz}{10^6 Hz}= 98.9 MHz

Find the slope of the line shown on the graph to the right
damaskus [11]

Answer:

1

Step-by-step explanation:

We need two points to find the slope

( -1,0) and ( 2,3)

We can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 3-0)/(2 - -1)

  = (3-0) / ( 2+1)

  = 3/3

  = 1

The slope is 1
