Explanation:

Part (a)

Step1: Identify percentages for faucet, shower, bath

Faucet: \(15\%\), Shower: \(17\%\), Bath: \(2\%\)

Step2: Sum the percentages

\(15 + 17 + 2 = 34\)

Step1: Identify percentages for dishwasher, clothes washer

Dishwasher: \(27\%\), Clothes Washer: \(21\%\)

Step2: Sum the percentages

\(27 + 21 = 48\)? Wait, no, wait the circle graph: Wait, looking at the labels: Wait, the legend: Bath (black), Dishwasher (striped), Other, Leaks, Faucet (dark gray), Shower (checkered), Clothes Washer (white), Toilet (light striped). Wait, the percentages: Faucet \(15\%\), Shower \(17\%\), Bath \(2\%\); Dishwasher \(27\%\), Clothes Washer \(21\%\)? Wait no, let's re - check the circle graph. The labels: The circle graph has: Toilet \(27\%\), Clothes Washer \(21\%\), Dishwasher? Wait, maybe I misread. Wait the user's handwritten: For part (b), the handwritten says \(21 + 2 = 23\)? Wait no, maybe the dishwasher is \(2\%\)? Wait no, the legend: Let's look again. The circle graph: The percentages are: Toilet \(27\%\), Clothes Washer \(21\%\), Dishwasher? Wait, the small slices: 2% (Bath), 2% (Leaks), 2% (other?); Faucet \(15\%\), Shower \(17\%\), Dishwasher? Wait, maybe the dishwasher is \(2\%\)? No, that can't be. Wait the user's handwritten for part (b) is \(21+2 = 23\), maybe dishwasher is \(2\%\) and clothes washer is \(21\%\). So:

Step1: Identify percentages for dishwasher, clothes washer

Dishwasher: \(2\%\)? No, that doesn't make sense. Wait, maybe the original problem: Let's re - examine the circle graph. The "Household Water Use" circle graph: The slices: Toilet \(27\%\), Clothes Washer \(21\%\), Dishwasher? Wait, the checkered is Shower \(17\%\), dark gray Faucet \(15\%\), black Bath \(2\%\), striped Dishwasher \(27\%\), white Clothes Washer \(21\%\), and other slices: Leaks \(2\%\), Other \(2\%\), and maybe another \(2\%\). Wait, maybe the dishwasher is \(27\%\) and clothes washer is \(21\%\)? But the handwritten says \(21 + 2=23\), so maybe dishwasher is \(2\%\) and clothes washer is \(21\%\). So:

Step1: Identify percentages

Dishwasher: \(2\%\), Clothes Washer: \(21\%\)

Step2: Sum

\(2+21 = 23\)

We need to find two uses whose percentages add up to about \(50\%\). Toilet is \(27\%\) and Clothes Washer is \(21\%\), \(27 + 21=48\), close to \(50\%\). Or Toilet (\(27\%\)) and Shower (\(17\%\)): \(27 + 17 = 44\). Toilet (\(27\%\)) and Dishwasher (\(27\%\)): \(27+27 = 54\), which is close to \(50\%\). Wait, the user's handwritten answer is "clothes washer and toilet". Let's check: Clothes Washer \(21\%\), Toilet \(27\%\), \(21 + 27=48\), which is about half (50%). Another option: Toilet (\(27\%\)) and Dishwasher (\(27\%\)): \(27 + 27 = 54\), also close. But the user's answer is clothes washer and toilet. Let's go with that.

Answer:

\(34\%\)
