The attached diagram shows the QUANTITIES and concentrations of each container. The first container has x liters in it ("how many liters of 10%..."). The second container has 30 liters (and 50% of that is acid). The third container has x + 30 liters (because you dumped the first two containers into the third container), and 20% of that is acid.
Write an equation that shows how the acid adds up:
10% of x plus 50% of 30 equals 20% of (x + 30).
You should add 90 liters of the 10% solution.
Answer:
We know that, i = √-1 => i² = -1
- <u>-50 + 4i</u> is the right answer.
The answer is 41.5. It’s pretty simple
Answer:
10^2 = 100
100 x 3.14 = 314(area of circle)
314 x 2 = 628(area of both two circles/base and top)
2 x 3.14 x 10 = 62.8(circumference),
62.8 x 6(height) = 376.8
Add areas:
376.8 + 628 = 1,004.8 m2 is your answer.
Answer:
3 because 9x3 is 24 and that’s the closest u can get unless u turn into fraction
