Answer:
3.84 * 10^8 meters
Step-by-step explanation:
As the speed of light is 300,000,000 meters/second and the time that the light takes to go from the moon to the Earth is 1.28 seconds, we can find the distance using the formula:
Distance = speed * time
So we have that:
Distance = 300,000,000 * 1.28 = 384,000,000 meters
In cientific notation, we need the first number to be in the interval from 1 to 10, so we have 3.84, and we have to multiply by 10^8 to reach our result, so we have:
Distance = 3.84 * 10^8 meters
The numbers of bars that the team have to get from each company in order for the total cost to be equal is 40.
<h3>What is the purchase about?</h3>
Since n = numbers of bars purchase.
y= total cost in dollars
Company A = 0.75n
Company B = 10 + 0.50n
Therefore, to find the numbers of bars that the team would need to purchase from each company in order for the total cost to be equal =
0.75n = 10 + 0.50n
0.2n = 10
n = 40
