I believe that is c if I'm wrong I'm very sorry
Answer:
im not great at math but i believe the answer is 24mm^2
Step-by-step explanation:
triangle area formula- (B*H)/2
large triangle:
6+4+2=12
H=12
B=5
5*12=60
60/2=30
small trangle:
4*3=12
12/2=6
30-6=24
therefore answer should be 24mm^2
Answer:

Step-by-step explanation:
Answer:
Gabe needs 20 liters of the 40% solution.
He also needs 40 liters of the 70% solution.
Step-by-step explanation:
Equation:
acid + acid = acid
0.40x + 0.70(60-x) = 0.60*60
40x + 70*60 - 70x = 60*60
-30x = -10*60
x = 20 liters
Gabe needs 20 liters of the 40% solution.
He also needs 40 liters of the 70% solution.
