This isn't a math question and should be in the science section. However, I will still answer the question. The answer is choice B.
-------------------------------------------------------------------------------------------------------------
Here's a further breakdown
A. False. The radiation or energy from the sun can travel through air or else you wouldn't feel the sun's rays. Also, plant life wouldn't be alive without that energy going through the air.
B. True. The rays travel through a vacuum of space. If they couldn't travel through space, then the same problem comes up as in choice A: the issue of not feeling the sun's rays.
C. False. They rays have different frequencies. Because there are many wavelengths (see choice D below), this means there are different frequencies. Recall that f = 1/w where f is the frequency and w is the wavelength.
D. False. The rays are made of different wavelengths. The visible light portion is what we can see, though there is a lot more to the electromagnetic spectrum (eg: ultraviolet light).

So once again, the answer is choice B
Answer:
0.349
Step-by-step explanation:
Write an equation to show all elements:
Cost of 4 lots of b (beads) + cost of 4p (pendants) = $18.80
Put values in;
9.29 + 4p = 18.80
4p = 18.80 - 9.20
4p = 9.60
p = 2.40 cost of each pendant
Calculate the number of hours between 4 PM and 10 AM:
4 PM to 4 AM is 12 hours.
4 AM to 10 AM is 6 hours
Total hours is 12 + 6 = 18 hours.
18 hours x 70 km/hr = 1,260 km total.
9 miles he traveled on tuesday, why? because if you were to draw a line connecting the dots and went to the x coordinate 60 (hour in minutes) on the line you drew, you can see its also at 9 miles on the y coordinate
