Sarah made 2 3/4 cup of lemonade she drank 1 and 1/2 cups for lunch how much lemonade does she have left

1 1/4 cup

Step-by-step explanation:

Make the mixed fractions regular fractions by multiplying the outside number by the denominator and then adding it to the numerator. For example

2 3/4

2 * 4 = 8 + 3 = 11

2 3/4 = 11/4

You should get 3/2 for how much she drank.

Now make sure your denominators are the same. Multiply both the numerator and denominator of the amount she drank by two to get 6/4

Then subtract the fractions.

11/4 - 6/4 = 5/4

Now make that into a mixed fraction.

She has 1 1/4 cup left

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
