Astronomers measure large distance in light years one light year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles suppose a star is 13.4 light years from earth in scientific notation how many miles away is it

Step-by-step explanation:

To calculate the distance between the star that is 13.4 light years away from the earth, you just have to multiply 13.4 by 5,880,000,000,000, which is how many miles there are in a light year.

So you´d get:

To convert this into scientific notation, you just have to count how many numbers are there after the first numeric value, in this case how many numbers are there after the first seven.

There are 13 numbers after the first seven now you just add a decimal point after the seven and add a , the X is the number of numeric values after the decimal point, since in this case there are 13 numeric values after the decimal point we added, we just add the 13 instead of the X:

And the number in scientific notation would be:

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

answer:
