4 cups of white paint since there was 4 cups of red paint
Answer:
D
Step-by-step explanation:
1 liter = 33.8 fl oz
Hence
2 liter = 33.8 * 2 = 67.6 fl oz
Now, we need to determine, how many 8 fl oz glasses can be filled with 67.6 fl oz of juice. For that, we need to divide total amount of juice (in fl oz) by 8. We will get:

So there is enough juice to fill around 8.5 glasses, but we need to know how many FULL GLASSES can be filled, NOT PARTIAL.
Thus, we can say:
8 glasses max can be filled with 2 Liters of juice
Answer choice D is right
Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5
