Heath needs to end up with 10L of solution,
of which 9L is bleach. So let m = liters of 20%
solution needed. Then .20m liters of that are bleach.
He must then add p liters of bleach to make
a total of 10 L. That is, p + m = 10. So the system is
m + p = 10, .20m + p = 9. Solving,
<span>m = 1.25 L 20% solution, and thus p = 8.75 L bleach.</span>
Answer:
D
Step-by-step explanation:
3:5 is equivalent(equal) to 15:25.
15÷5 and 25÷5 is equal to 3:5.
Hope this helped!
(5^-2)= (1/5^2)... (1/25) now cube that so it will be 1/15625. Hope that helps
there are many types of functions this includes linear function (straight line graph) eg y=3x+2 , quadratic function (u shaped curve) eg y=x², logarithmic function, exponential function and etc
C=100.I used the Pythagorean theorem just in case next time you run into this problem.
