○ 9 milliliters
○ 90 milliliters
○ 900 milliliters
○ 9,000 milliliters

question 3 (multiple choice worth 2 points)
(12.03 lc)
which tool is most appropriate for measuring the volume of a pitcher of lemonade?
○ beaker
○ graduated cylinder
○ meter stick
○ ruler

Explanation:

First Question (Watering Can Problem)

Step1: Recall unit conversion

We know that \( 1 \text{ liter} = 1000 \text{ milliliters} \), so \( 10 \text{ liters} = 10\times1000 = 10000 \text{ milliliters} \).

Step2: Calculate remaining volume

She uses \( 1000 \text{ milliliters} \), so remaining volume is \( 10000 - 1000 = 9000 \text{ milliliters} \)? Wait, no, wait the original problem: Wait, the first question: "Aloha fills up a watering can with 10 liters of water. She uses 1,000 milliliters to water plants. How many [milliliters left?]". Wait, let's re - do:

Step1: Convert liters to milliliters

Since \( 1 \text{ L}=1000 \text{ mL} \), then \( 10 \text{ L}=10\times1000 = 10000 \text{ mL} \).

Step2: Subtract used volume from total volume

Used volume is \( 1000 \text{ mL} \), so remaining volume \( V = 10000 - 1000=9000 \text{ mL} \)? Wait, but the options: Wait, maybe I misread. Wait the options are 9, 90, 500, 9000. Wait, maybe the original problem is "10 liters, uses 1000 milliliters", so 10 liters is 10000 mL, 10000 - 1000 = 9000 mL. So the answer is 9,000 milliliters.

• A beaker is used for holding or mixing liquids, not precise volume measurement.
• A graduated cylinder is designed for measuring the volume of liquids precisely.
• A meter stick and a ruler are used for measuring length, not volume. So the most appropriate tool is a graduated cylinder.

Answer:

9,000 milliliters (the option with 9,000 milliliters)
