The solution is 25% acid, which means 2.5 liters acid (10 x .25).
<span>you need that 2.5 liters to be 10%, or 1/10th the total. </span>
<span>the total would have to be 25 liters (2.5 x 10) so when you add to 10 to get 25 you get </span><span>15 liters. Hope I helped!</span>

Step-by-step explanation:
The answer is c.
The discount is 20% off, right? What's 20% of 35? To do that, you need to do the problem 35*.20, because .20 is equivalent to 20%. Remember how it is 20% off? That means subtract here. When you do 35*.20, you'll get 7. Now, subtract 7 from 35. 35-7=28, and your answer is in money; $28.00. :)

Answer:
5.12 seconds to the nearest hundredth.
Step-by-step explanation:
When the ball hits the ground h = 0 so
-16t^2 + 81t + 5 = 0
t = [ -81 +/- sqrt ((81^2 - 4 * -16 * 5)]/ (2*-16)
= (-81 +/- sqrt 6881) / -32
= 5.12 , -0.6
So the answer is 5.123 seconds.
