Answer:
[H^+] = Antilog[-6]
Step-by-step explanation:
Even though the question is incomplete, let us try to correctly derive the equation used to find the hydrogen ion concentration.
pH=−log[logH^+]
-pH = log[H^+]
[H^+] = Antilog[-pH]
Since pH =6
The equation is;
[H^+] = Antilog[-6]
Answer:
160°
Step-by-step explanation:
Minor Arc NR is equal to the measure of its central angle, S.
S and 20 are supplementary angles, so they add up to 180.
So, s +20 =180
S = 160, so NR = 160 as well
Answer:
The question is not clearly stated, but I can correctly infer that you wanted to ask the question below:
Out of 150 members, 120 took part, what is the percentage of the total that took part:
Answer:
80%
Step-by-step explanation:
The question is asking us to find what percentage of 150 is 120
Let the percentage of 150 that is 120 be x
x % of 150 = 120
x/100 × 150 = 120
0.01x × 150 = 120
0.01x = 120 ÷ 150 = 0.8
x = 0.8 ÷ 0.01 = 80
∴ 120 = 80% of 150
