Jada makes sparkling juice by mixing 2 cups of sparkling water with every 4 cups of apple juice. How much sparkling water does Jada need if she uses 16 cups of apple juice?

8 cups of sparkling water

Step-by-step explanation:

This is a ratio problem, the ratio is 2:4 because there are 4 cups of apple juice for every 2 cups of sparkling water, if there are 16 cups of apple juice, there will have to be 8 cups of sparkling water because if you do something to one part of the ratio, you have to do it to the other part too. you have to multiply 4 x 4 to get 16, so if you multiply 2 and 8, you get 16, which then makes the ratio equivalant and correct

12cm

the answer is d

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
