Answer:
The answer is B.
Step-by-step explanation:
7x4 is 28 which means you have to multiply 3x4. That gives you 12. 28:12 is the proper ratio. (Hope this helped!)
The first question is the second answer
Answer:
0.8
Step-by-step explanation:
Given that:
Speed of light = 3 * 10^8 m/s
Distance of sun to Mars = 230,000,000 meters
How many seconds does it take for sunlight to reach Mars?
Using the relation :
Speed = distance / time
Hence ;
Time = Distance / Speed
Time = 2.3 * 10^8 / 3 * 10^8
Time = 0.766
Time = 0.8 ( nearest tenth)
$5,182.12
or
$3,367.88
I think it's one these two.
