For a cylinder we want the area of the base times the height for a volume.
That's a radius of 5.
A = 6 ( π 5² ) = 150π mm³
Answer: C
Answer:
- 35 grams of 11.43% solution
Step-by-step explanation:
The end solution has same volume as initial volumes of mixture.
The concentration of solution is calculated as below
- 10*0.15 + 25*0.1 = 4 g
- 4 / 35*100% = 11.43% (rounded)
Answer:
x = 5, x = -5
Step-by-step explanation:
First, you can notice both terms of the equation are divisible by 2, so you can factor it out to get:
2(x^2 - 25) = 0
You can recognize the expression x^2 - 25 as the special product for the difference of squares, so it would be factored into (x + 5)(x - 5). When we plug it in we get:
2(x + 5)(x - 5) = 0
Now, we can use the zero-product property to get two equations:
x + 5 = 0
-and-
x - 5 = 0
Solving them both we get:
x = 5, x = -5
Cross multiply:-
Y2 - y1 = M(x2 - x1)
-y1 = M(x2-x1) - y2
y1 = y2 - M(x2 - x1) Answer
