the degree is the largest exponent on the variable, so it would be 3-
Answer:
7.5 L of 10% solution and 22.5 L of 30% solution
Step-by-step explanation:
Volume of 10% solution plus volume of 30% solution = total volume of 25% volume.
x + y = 30
Acid in 10% solution plus acid in 30% solution = total acid in 25% solution.
0.10 x + 0.30 y = 30 × 0.25
0.10 x + 0.30 y = 7.5
Solve the system of equations, using either substitution or elimination. I'll use substitution:
x = 30 − y
0.10 (30 − y) + 0.30 y = 7.5
3 − 0.10 y + 0.30 y = 7.5
0.20 y = 4.5
y = 22.5
x = 30 − y
x = 7.5
Sarah needs 7.5 L of 10% solution and 22.5 L of 30% solution.
The length of the curve is
The answer is D :)
I hope this helps! Let me know if you need help with anything else! I'd be happy to help in anyway I can! :D
Add goals and assists to find the total points:
801 + 1049 = 1850 total points.
Now divide total points by total games to get points per game:
1850 / 1767 = 1.0469
Rounded to nearest hundredth = 1.05 points per game
