lexia is making orange juice the recipe says it takes 4 parts water and 2 parts orange concentrate. lexia put 16 cups of water into a pitcher how much orange concentrate does she need to mix into the pitcher?

8

Step-by-step explanation:

A way to solve it is to make 4 parts of water and 2 parts orange concentrate into a fraction. That would create 4/2. Next, the problem tells you that Lexia has put 16 cups of water. The numerator 4 represents the amount of water where as 2 represents orange concentrate. If 16 represents water also that now makes the equation 4/2=16/x. To get 4 to 16 you multiply by 4, therefore you must do the same to the denominator 2 and multiply it by 4. You end up with 8 know making the equation read 4/2=16/8.                              

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
