Martha is making lemonade. She needs lemon juice, sugar and water. She needs 1 cup of lemon juice and 3 cups of water. Which cup measure would be an appropriate measure for the amount of sugar needed? A) 0.61

B) 0.23

C) 0.50

D) 0.56

0.61 ( A )

Step-by-step explanation:

The standard proportion of Sugar, lemon juice and water needed to make a Lemonade is Usually 1 cup each

But If you Intend to make Your lemonade less sweet you can increase the water or reduce the amount of sugar to ≈ 1 ( i.e. less than 1 but approximately = 1 )

Hence The appropriate amount of sugar needed will be = 0.61

0.50

answer: im sorry i dont get it

step-by-step explanation:

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

(a + b) (a^2 - a b + b^2)
