For an experiment, a scientist needs 1/2 cup baking soda for 4/5 liter of water. Using this ratio, how much baking soda is needed for one liter of water? Answer choices-

4/10 cup

5/8 cup

8/5 cups

10/4 cups

5/8 cup of baking powder.

Step-by-step explanation:

Hence, using the ration given in the above question:

4/5 liter of water = 1/2 cup of baking soda

1 liter of water = x cup of baking powder

Cross Multiply

4/5 liter of water × x cup of baking powder = 1 liter of water × 1/2cup of baking powder

x cup of baking powder = 1 liter of water × 1/2cup of baking powder/4/5 liter of water

x cup of baking powder = 1/2 ÷ 4/5

x cup of baking powder = 1/2 × 5/4

x cup of baking powder = 5/8 cup of baking powder.

Therefore,

5/8 cup of baking soda is needed for one liter of water.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
