Answer:

  3.2×10⁷ liters/week

Step-by-step explanation:

[tex]\dfrac{1.2\cdot 10^6\,gal}{1\,day}\cdot\dfrac{7\,day}{1\,week}\cdot\dfrac{8\,pint}{1\,gal}\cdot\dfrac{1\,L}{2.11\,pint}=\dfrac{1.2\cdot 10^6\cdot 7\cdot 8\,L}{2.11\,week}\\\\\approx 3.2\cdot 10^7\,\dfrac{L}{week}[/tex]

Answer:

A. How many liters per week is this?

31,848,341.232 liters per week

B. Put in scientific notation

3.1848341232 × 10⁷ liters per week

Approximately = 3.2× 10⁷ liters per week

Step-by-step explanation:

A. Nestle water pumps 1.2 Million gallons per day = 1,200,000

i. Given that 1 week = 7 days

1 day = 1,200,000 gallons produced

7 days = 1,200,000 × 7 days

= 8,400,000 gallons produced in one week ( 7 days)

= 8,400,000 gallons per week

ii. Given that 8 pints = 1 gallon

1 gallon = 8 pints

8,400,000 gallons produced in one week = 8,400,000 × 8 pints

= 67,200,000 pints per week

Therefore 67,200,000 pints are produced in one week.

III. Given that 2.11 pints = 1 liter

If 2.11 pints = 1 liter

67,200,000 pints produced in one week = X liters

Cross multiplying

2.11X = 67,200,000

X = 67,200,000 ÷ 2.11

X = 31,848,341.232 liters per week

B. Put in scientific notation

3.1848341232 × 10⁷ liters per week

Approximately = 3.2 × 10⁷ liters per week
