Answer:
1.5 + 10^8.
Step-by-step explanation:
(3 x 10^2) x (5 x 10^5)
= 3 x 5 * 10^2 x 10^5
= 15 x 10^(2 + 5)
= 15 x 10^7
= 1.5 + 10^8.
The answer to your problem will be negative slope you’ll thank me later
The total mass was 149.5 grams.
Setting up an equation, we have that the sample size, 39.1, is 5 3/4 (5.75) grams less than 3/10 of the total mass; this gives us
39.1 = 3/10x - 5.75
Adding 5.75 to both sides, we have
44.85 = 3/10x
Multiplying both sides by 10,
448.5 = 3x
Dividing both sides by 3,
149.5 = x
