Answer:
the other sides are 9 and 12
Step-by-step explanation:
use the Pythagorean theorem.
a^{2} +b^{2} =c^{2}
you know that c^2 is 225 because 15*15=225
a^{2} +b^{2} =225
(from here on I just plugged numbers in)
3:4=9:12
9^{2} +12^{2} =225
81+144=225
225=225
Yaaaaay!

Answer:
93.6 ml
Step-by-step explanation:
12% of that 780 ml is pure acid: 0.12(780 ml) = 93.6 ml
The slope is the change in Y over the change in X:
Slope = (3 -12) / (4-0)
Slope = -9/4
The answer is the 3rd choice.
