Answer:
B) {-2, 2, 5}
Step-by-step explanation:
Coordinate points on the graph
(1,5), (3,5) , (4,2) and (6, -2)
Range is a list of y values so in this case range is:
{-2, 2 , 5}
<span>Dr. Graham currently has two acid solutions.
60% acid AND 20% acid </span>
Dr. Graham needs 30 L of a 50% acid solution
We set up 2 equations in which s = 60% acid and t = 20% acid
A) s + t = 30
B) .60s + .20t = (.50 * 30)
We multiply equation A by -.20
A) = -.20s -.20t = -6 then we add it to B)
B) .60s + .20t = 15
.40s = 9
s = 22.5
t = 7.5
So, she needs to mix 22.5 liters of 60% acid with 7.5 liters of 20% acid.

Answer:
57:38
Step-by-step explanation:
3/2(19):x
3:2
3x = 2 * 3/2 * 19
3x = 57
x = 19
Since the ratio is 3:2, then the scores at half-time were 57:38
