If logarithms confuse you, here’s a simpler way to approach this problem: What power of 2 equals 128? We know that 2^3 equals 8, thus 2^4 must equal 16. Continuing to double each time, we find that 2^5 equals 32, 2^6 equals 64, and 2^7 equals 128. Hence, the value of log₂128 is 7.
Answer:
Someone has previously provided an answer to this question, and I must attribute it to writersparadise. All credit goes to him/her.
Step-by-step explanation:
There can be various responses to this query. Usually, the next number following 16 has digits that add up to 8.
Explanation:
First number 31 – The digits add up to 3 + 1 = 4
Second number 1031 – The sum of the digits is 1 + 0 + 3 + 1 = 5
Third number 402 – The digits sum to 4 + 0 + 2 = 6
Fourth number 16 – Adding the digits gives 1 + 6 = 7
Thus, the missing number could either be the single digit 8 or any of these two-digit options: 17, 26, 35, 44, 53, 62, 71, or 80. It may also include larger numbers consisting of the digits from the mentioned two-digit figures combined with 0, like 260 or 7001.

There are a total of 20,000 available numbers. To ascertain how many phone numbers are available, the number of digits in each number must be known. Here, I will assume each number has 7 digits. This leads to the format starting with either 373XXXX or 377XXXX, where each X can be any digit from 0 to 9. This results in 10 options for each X. Therefore, there are 10×10×10×10 = 10,000 distinct phone numbers starting with 373 and another 10,000 with 377, totaling 20,000 numbers.
Let y represent the gallons of water left in the barrel, and let x represent the minutes that have passed. Water escapes the barrel at a rate of 1 gallon for every 10 minutes. Consequently, the appropriate linear equation for this scenario is shown in the attached graph.
The predicted outcome is 83 minutes. I hope this is useful to you.
