Answer:
62.5 oz of 100%
Step-by-step explanation:
Let p represent the number of ounces of pure syrup. Then (100-p) is the number of ounces of 60% syrup. The amount of maple syrup in the desired mix is ...
p +0.60(100 -p) = 0.85(100)
0.40p +60 = 85 . . . . . . . . . . . simplify
0.40p = 25 . . . . . . . . . . subtract 60
p = 62.5 . . . . . . . . . divide by 0.4
62.5 ounces of pure syrup should be mixed with the diluted syrup to make 100 ounces of 85% maple syrup.
_____
The other 37.5 ounces will be 60% syrup.

Answer:
9.6 seconds
Step-by-step explanation:
The equation for projectile motion in feet is 
where 
is the initial velocity in ft/s and 
is the initial height in feet.
We are given that the initial upward velocity is 
and the initial height is 
. Thus, plugging these values into our equation, we get 
as our equation for the situation.
The firework will land, assuming it doesn't explode, when 
, thus:
Since time can't be negative, then the firework will land after 9.6 seconds, assuming it doesn't explode at the time of landing.
