Answer:
2.25 (or ) g/mL
<u>Skills needed: Density</u>
Step-by-step explanation:
1) Briefly, let's cover what density is:
- It is
- Measures the mass per unit of volume
- In this situation the formula for density is:
---> is the final mass
---> is the initial mass
---> is the final volume
---> is the initial volume
2) In this case, we start out with a mass of 180 grams as stated in the problem, and also 50 mL of water initially.
This means that:
- is 180 g
- is 50 mL
3) Also, we end up with 270 g in mass, and 90 mL of water finally.
- is 270g
- is 90 mL
4) We can find density by substitute given the values above:
5) Our answer is 2.25 g/mL (since mass is grams (g), and volume is milliliters (mL) in the problem above).

Answer:
The answer to your question is $5.625 x 10⁸
Step-by-step explanation:
Data
Jackpot = 4.5 x 10⁷ dollars
Number of lotto players = Shirley + 7 friends
= 8
Process
1.- Divide the Jackpot by seven
4.5 x 10⁷ / 8
- Convert scientific notation to normal moving the decimal point seven places to the right.
45000000 / 8
- Result
$5625000 or in scientific notation = $5.625 x 10⁶
2.- Conclusion
Each player will receive $5.625 x 10⁸
