A and B Definitely. 3 and 17, -3 and -17
Since we are calculating the amount that he got correct, we must divide the numerator by the denominator or make the denominator equal 100. I will do it the second way as it is easier in this case.
25*4 = 100
21*4 = 84
84/100 = 0.84
As a decimal, Andrew got 0.84 of his test correct. Hope this helps!
<span>Length = x Width = 2x
Perimeter = 2 * length + 2 * width
= 2x + 4x
= 6x
6x = 66
x = 11

Answer:
Both of the lines that goes to A is the same length so just find the length measurement of the line fro C to A and the write that as the answer.
Step-by-step explanation:
Answer:
The 
of the clean compound is approximately 10.495.
Step-by-step explanation:
If the cleaning ion concentration of the cleaning compound is ![[H^{+}] = 3.2\times 10^{-11}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%20%3D%203.2%5Ctimes%2010%5E%7B-11%7D)
, then the , no unit, of the compound is:
![pH = -\log_{10} [H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-%5Clog_%7B10%7D%20%5BH%5E%7B%2B%7D%5D)
(1)
The of the clean compound is approximately 10.495.
