Answer:
- premium: 165 gallons
- water: 120 gallons
Step-by-step explanation:
Let 'a' represent the amount of 95% antifreeze in the mix. Then the amount of water is (285 -a). The mix has this amount of antifreeze in it:
0.95a +0(285 -a) = 0.55(285)
a = 0.55/0.95(285) = 165 . . . gallons of 95%
285 -a = 285 -165 = 120 . . . . gallons of water
There are 120 gallons of water and 165 gallons of premium antifreeze in the mixture.
Answer: C
Explanation:
Since tan(H) equals 1, we can conclude that angle H equals 45 degrees. Therefore, we know that it is a 45-45-90 triangle. Therefore, since both legs are equal, sin or cos doesn’t matter. Therefore, C is correct. (Draw it for yourself, it helps)

Answer:
The blue area is 2a
Step-by-step explanation:
So, first, let's scope out the problem and split it up.
We have +10 on both sides, so we don't need to worry about that.
Now, 5a-3a+___=4a
So, if we do 5a-3a, we get 2a
So, 2a+___=4a
now, we can subtract 2a from b oth sides, and we are left with 2a
So, your answer is 2a!
