Answer:
And if we convert to megahertz we got:
Step-by-step explanation:
For any mechanical wave we have the following general relationship:
where:
v represent the speed of the wave = 299790000 m/s
represent the wavelength for the radio station
f represent the frequency of interest
If we solve for the frequency we got:
And replacing the values we got:
And if we convert to megahertz we got:
Hey there!
Let's create a systems of equations with x and y to find our numbers.
x=5y
x-y=1480
Let's plug our x value into the second equation.
5y=y=1480
4y=1480
y=370
Now we multiply this number by five as the first equation says to get our x.
x=1850
Our numbers are 1850 and 370.
I hope this helps!
Answer:
D
Step-by-step explanation:
y =94..multiply 5 by94 and get 470
Answer:
<h3>6 days</h3>
Step-by-step explanation:
Given the inequality expression of the total cost (c) in dollars of renting a car for n days as c ≥ 125 + 50n
To get the maximum number of days for which a car could be rented if the total cost was $425, substitute c = 425 into the expression and find n
425 ≥ 125 + 50n
Subtract 125 from both sides
425 - 125 ≥ 125 + 50n - 125
300≥ 50n
Divide both sides by 50
300/50≥50n/50
6 ≥n
Rearrange
n≤6
<em>Hence the maximum number of days for which a car could be rented if the total cost was $425 is 6days</em>

Answer:23 cm
Step-by-step explanation:
Because it would equal the same amount because there are 10 mm in a cm
