Answer:Third option is correct.
Step-by-step explanation:
Certain high-frequency radiations are likely to cause harm to astronauts landing on Mars.
Ultraviolet is the most suitable to study this harmful radiation on Mars.
It has highest frequency than X-rays but shorter than visible rays.
It is harmful is nature as it causes painful sunburns and premature ageing of the skin etc.
Hence, Third option is correct.
Answer:
Given the options: Infrared, Radio waves, Ultraviolet and Visible light, ordering them by frequency (for highest to lowest) we get:
Ultraviolet
Visible light
Infrared
Radio waves
Knowing that high-frequency radiations are likely to cause harm to astronauts landing on Mars, then the detector of Ultraviolet is most suitable
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
3 > t/3
Multiply each side by 3
3*3 > t/3 *3
9 > t
t < 9
There is an open circle at 9, since the symbol is less than
The line goes to the left.
Answer:
arrow going from 9 to -infinity (open circle)
Step-by-step explanation:
equalize equation by multiplying both sides by 3 to obtain the equation 9>t
then simply plug in numbers to see if they check out, ie: 3> 4/3 makes sense, but 3> 10/3 doesn't.
Draw the arrow to accommodate for the answers that DO fit.
open circle, because it doesn't work for t=9

Solution:
We are given that
Ballpoint pens cost $1.50 a dozen for the first 200 dozen a store buys from a wholesaler.
$1.25 a dozen for those bought in addition to the first 200 dozen.
we have been asked to find
If the store buys 250 dozen pens from the wholesaler, then what is the average cost of ballpoint pens per dozen.
Cost of first 200 dozens of pens
Cost of 50 dozens of pens
Total cost of 250 dozens of pens
Average cost per dozen
