A communications satellite transmits a radio wave at a frequency of 5 • 109 Hz. What is the signal’s wavelength? Assume the wave

iVinArrow [24]

As we know that
<span>speed of an EM wave is 3x10^8
And also
Velocity =Frequency x Wavelength
so for wavelenht
Wavelength = Velocity/ Frequency
so
wavelength = 3 x 10^8 / 5 x 10^9
= 3/50 or 0.06m
hope it helps</span>

A one day trip to new york, mary spent $6.25 for breakfast and 8.95 for lunch. She can spend no more than an average of $8.50. H

Mary spent $10.30 on dinner to stay in budget.

Step-by-step explanation:

Amount spent on breakfast = $6.25

Amount spent on lunch = $8.95

Amount spent on dinner = x

Average = $8.50

Average = $\frac{Sum\ of\ values}{No.\ of\ values}$

$8.50 = \frac{6.25+8.95+x}{3}\\8.50=\frac{15.20+x}{3}$

Multiplying both sides by 3

$8.50*3=\frac{15.20+x}{3}*3\\25.50=15.20+x\\25.50-15.20=x\\x=10.30$

Mary spent $10.30 on dinner to stay in budget.
