A truckload of apples weighs 2550 lbs. If 5 (exact) apples weigh 1250 g, how many apples are in the truck?

There are 4,626 apples in the truck.

Explanation:

Mass of  5 apples = 1250

Mass of an apple =

Mass of apples in the truck = 2550 lbs

1 lbs = 453.592 g

Let the number of apples with mass of 2550 lbs be a.

4,626.63 ≈ 4,626

So, there are 4,626 apples in the truck.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
