Answer:24
Step-by-step explanation:
You pick a one of two card, roll a 6 sided die, spin a two sided spinner, and find the sum. How many different sums are possible? Please help
I will assume all the numbers are different. and no 3 produce the same sum.
Then there will be 2*6*2=24 different possible outcomes.
Let x be the volume (liters) of pure (at 100%) acid needed
Let y be the volume (liters) of the other acid (at 10%) needed
The final solution will be:
a) x+ y = 63 liters, AND their respective concentration in acid: is
100% x & 10% :y that will generate 63 liters at 20%
b) x +0.1 y = 63x 0.2 = 12.6
Let's solve this system of 2 equations:
x + y =63
x + 0.1 y = 12.6
Solving it will give you:
x= 7 liters at 100%
y = 56 liters at 10%
