The speed of light is 1.86×10^5 miles per second. how many miles will light travel in 4,200,000 seconds?

Step-by-step explanation:

Let be "x" the amount of miles light will travel in 4,200,000 seconds.

Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:

According to the exercise, light travels miles in 1 second.

Therefore, based on this data, you can set up the following proportion:

And finally, you must solve for "x" in order to find its value.

(Remember the Product of powers property: )

Then:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

irrational, cannot
