Because they both have the same exponent, just add the numbers together:

5.9 + 4.9 = 10.8

So now you have:

5.9 x 10^24 + 4.9 x 10^24 = 10.8 x 10^24

A scientific number can only have 1 number to the left of the decimal, so you need to move the decimal one place to the left. When you move the decimal to the left you add to the exponent.

The answer is: 1.08 x 10^25

A bag of baseballs cost 9.99 dollars and each bag contains 6 baseballs. if the baseballs were sold individually, how much would
user100 [1]

The price of each ball in a baseball bag would be 1.665 dollars

It is given that,

The cost price of a bag of baseball bag = 9.99 dollars

The number of balls in each bag = 6 baseballs

Now, we need to find the cost of one baseball if it were to sold individually

To find the cost of one quantity out of a bunch we divide the bunch price with the number of quantities in the bunch

Here, in this case

The cost price of each ball = \frac{Total cost of a baseball bag }{number of balls in each bag}

= \frac{9.99}{6}

= 1.665 dollars

Hence, the price of each ball in a baseball bag would be 1.665 dollars
