Answer:
3.6 hours.
Step-by-step explanation:
We work in terms of rates per hour:
1/9 + 1/6 = 1/x where x is the time for 2 pipes working together.
Multiply through by the LCD of 6, 9 and x ( which is 18x) :-
2x + 3x = 18
5x = 18
x = 3.6 hours.

Karen bought 48 ounce of Cheese.
A unit conversion is the expression of the same feature in a different unit of measurement. Time, for example, can be stated in minutes rather than hours, and distance can be translated from miles to kilometres, feet, or any other length measurement.
karen bought 3 pounds of cheese to serve at a picnic.
We know 1 pound = 16 ounces
So, to convert 3 pounds to ounce we have to multiply it 16.
Then, the Cheese in ounce is
= 16 x 3
= 48 ounces

Answer:
66.67 ml of 5% solution and 133.33 ml of 6.5% solution are mixed.
Step-by-step explanation:
Let 200 ml of 6% solution is formed by mixing x ml of 5% solution and y ml of 6.5% solution.
We can write the equation x + y = 200 ........ (1)
Now, x ml of 5% solution will contain ml of acid
Again, y ml of 6.5% solution will contain ml of acid.
So, mixing them together will give (0.05x + 0.065y) ml of acid in 200 ml of solution.
So, from the condition given we can write
⇒ 0.05x + 0.065y = 12
⇒ x + 1.3 y = 240 ........... (2) {Dividing both sides by 0.05}
Now, solving equations (1) and (2), we get
0.3y = (240 - 200) = 40
⇒ y = 133.33 ml
From equation (1) we get, x = 200 - 133.33 = 66.67 ml
Therefore, 66.67 ml of 5% solution and 133.33 ml of 6.5% solution are mixed. (Answer)
