Answer:
Option B
Step-by-step explanation:
The absolute value of a number is how far a number is from zero. We can use ' | | ' to represent the absolute volume of a number. The distance, or absolute value, of -8 is 8.
We can represent this by writing:
|-8| = 8
Option B should be the correct answer.
Answer:
it is NOT possible
Step-by-step explanation:
A number is divisible by 6 if it is even and divisible by 3. It is divisible by 3 if the sum of digits is divisible by 3.
The sum of digits of 152 is 1+5+2 = 8, which is not divisible by 3, so 152 is not divisible by 6.
You first look at the 10,000 places, in this number, the tens place is 90,000. Which is the 9. So you look at the thousands place and check of its 5 or more which means you have to change number or if its 4 or less than leave it. And the thousands place is 8,000 so the 9 has to become greater. So for my thinking, its 7,308,341. My best try
Answer:
7 days
Step-by-step explanation:
At 25% per day, it will take approximately 3 days to double the population, so approximately 6 days for the population to quadruple. Checking that number, we find it is not quite enough for the experiment, so another day is required.
"Guess and check" as a method of solution works especially well if you have an automated checker to evaluate your guess. A graphing calculator or spreadsheet can work well for this.
_____
We guess 3 days as the doubling time using the "rule of 72" that says the product of percentage and doubling time is about 72. That is, 72/25 ≈ 3. (This is only a very rough approximation of doubling time, best for rates near 8%.)
