no
Step-by-step explanation:
because if you divide 10 by 3 she will only be able to ride for 3 hours
Step-by-step explanation:
If x is the volume of pure water:
Initial + added = final
0.95 (840) + 0 (x) = 0.70 (840 + x)
798 = 588 + 0.70 x
x = 300
840 + x = 1140
You need to add 300 mL of pure water to obtain 1140 mL of the desired 70% solution.
Answer:
6, 8, 10
Step-by-step explanation:
The values must satisfy the pythagorean theorem .

Answer:
( x +2)² + ( y - 4)² = 81
Step-by-step explanation:
The equation for a circle in standard form is ( x – h)² + ( y - k)² = r², where the center is (h, k) and the radius is r.
Putting the question's given information into the formula gives you
[ x – (-2)]² + ( y - 4)² = (9)²
( x + 2)² + ( y - 4)² = 81
