There's a property of logs I want you to remember, that is:
log(a)ᵇ = b*log(a)
We'll be using this property to solve the question
<u>Finding x:</u>
log(2)ˣ = log(3)
x*log(2) = log(3) [using the property mentioned above]
x = log(3) / log(2) [dividing both sides by log(2)]
Hence, the correct answer is option E.
Answer:
5 laps
Step-by-step explanation:
We can use ratios to solve
3 minutes 15 minutes
----------------- = ------------------------
1 lap x laps
Using cross products
3x = 15
Divide each side by 3
3x/3 = 15/3
x = 5
He can do 5 laps
Answer:
See below.
Step-by-step explanation:
It is a mathematical statement that has been proven by using previously established statements (which are often other theorems).
Answer: True. Questions should be collecting unbiased data that can be used in fact-finding. Having questions that are unrelated would not benefit the questionnaire. The questions within the questionnaire are one of the most important things. So, your answer would be A) true.
