They are 1,000,000 and 100,000
Answer:
11.26
Step-by-step explanation:
pH = - log(H+ concentration)
[H^+] = 5.5 * 10^(-12)
pH = - log(5.5*10^-12)
pH = - (-11.26)
pH = 11.26
The answer is C, 238.125km
Answer: -2
Step by step Explanation: y=k/x
Replace y with 7 and x with -2
7=k/-2 gives you -14
then you replace k with -14 and x with 7
Y=14/7 gives you -2
Answer:
3 1/4
Step-by-step explanation:
3/4 + (1/3 ÷1/6) - (-1/2)
Subtracting a negative is adding
3/4 + (1/3 ÷1/6) +1/2
Parentheses first
Copy dot flip
3/4 + (1/3 * 6/1) +1/2
3/4 + 2 + 1/2
Get a common denominator
3/4 + 2 + 2/4
2 + 5/4
2 + 4/4 +1/4
2+1 + 1/4
3 1/4
