Why is this number not in scientific<br> notation?<br> 36.5 x 10^6<br> please help
andrew11 [14]

Answer:

The first number should be a number between 1 and 10 (see explanation)

Step-by-step explanation:

For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.

36.5 is not between 1 and 10, alternatively, you can rearrange it:

3.65 x 10^7      <----This would be the correct scientific notation

1. The formula for the velocity of an object is d=v/t, where v is the object, d is the distance traveled, and t is the time the
Arlecino [84]

Answer:

you need to isolate t or time

you need to know distance between sun and earth and velocity of them in order to calculate how long it takes for light to travel from the Sun to Earth

Step-by-step explanation:

t*(d)=(v/t)*t\\td= v\\\\\frac{td}{d} =v/d \\t=v/d

to find time you multiply t to both sides then you cancel t from where velocity is and you get velocity by itself

now you mulipy d to both side to get v over d and time by itself
