Arecipe for lemonade calls for 2 cups of sugar for every 1/2 cup of lemon juice. how many cups of sugar would be needed if you had 3 cups of lemon juice?

12 cups sugar

Step-by-step explanation:

there are a couple ways to do this...by unit rate or a proportion...

2 cups of sugar for every 1/2 cup of lemon juice

2 / (1/2) = 2 * 2 = 4the unit rate is 4/1or 4 cups of sugar for every 1 cup of lemon.

so if u have 3 cups of lemon, and 1 cup of lemon = 4 cups of sugar, then 3 cups of lemon would equal (4 * 3) = 12 cups of sugar

or set it up as a proportion...

2 cups sugar to 1/2 cup lemon = x cups sugar to 3 cups lemon

2 / (1/2) = x / 3cross multiply

(1/2)(x) = (3)(2)

1/2x = 6

x = 6 * 2

x = 12 cups sugar

either way u choose to do it will result in the same answer.

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
