(1.2×10^2) + (3.04×10^5)
They must be to the same power to add
3.04 *10^5 to change to the 2nd power (5-2=3) move the decimal 3 places to the right = 3040. * 10^2
1.2 * 10^2 + 3040 *10^2=
add the numbers keep the exponents the same
3041.2 * 10^2
there can only be 1 number before the decimal in scientific notation so we need to move the decimal 3 places to the left, which adds 3 to the exponent
3.0412 * 10 ^ (2+3)
3.0412 * 10^5
I think that
Every point is moved so that it is 2/3 as far from the y axis
should be the answer
Alright, so the first step we are gonna do to solve this problem is subtract since Mason ate 5 ounces of the peanuts and so, we need to subtract 5 out of 29.8.
29.8 - 5 = 24.8
So, now there is 24.8 ounces.
Now we move onto the next step which is division. As you can see in the question it says "Then he divides the rest of the peanuts equally among 4 friends."
24. 8 ÷ 4 = 6.2
Since the answer is supposed to be a decimal..that's your answer!
So overall, each of Mason's friends get 6.2 ounces of peanuts.
Hope this helps!

It's right u don't need a decimal
