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

The cost of belonging to a gym can be modeled by C(m)= 50m + 79.50, where C(m) is the total cost for m months of membership. Sta
erik [133]

Answer:

The slope is 50, which is the cost per month of the gym membership, and 79.50 is the y intercept.  It represents the initial cost to join the gym.

Step-by-step explanation:

C(m)= 50m + 79.50,

This is written in the form y= mx+b where m is the slope and b is the y intercept.

The slope is 50, which is the cost per month of the gym membership, and 79.50 is the y intercept.  It represents the initial cost to join the gym.

Which number line represents the solution set for the inequality 3(8-4x) < 6(x - 5)?
STatiana [176]

Answer:

x>3

Step-by-step explanation:

We are given with the inequation 3(8-4x) < 6(x - 5)

Dividing both sides in the above in equation by 3 we get

(8-4x)<2(x-5)

Distributing 2 over (x-5)

(8-4x)<2x-10

8-4x<2x-10

adding 10 and 4x on both hand sides we get

8+10<2x+4x

18<6x

Dividing both sides by 6 we get

3<x

Hence the solution to the given in equation is x>3
