Answer:
16.5
Step-by-step explanation:
Given that :
Number of refuge tour guides = 2
Number of tour guides = 11 per tour guide
Duration of each tour = 45 minutes
To calculate the person hour per day for the tour :
Person hour per day = (Total minute spent per day / 60)
Total minutes spent per day= (Number of tour guides) * (Number of refuge tour guides) * (duration per tour)
Total minute spent = (2 * 11 * 45) = 990 minutes
Person hour per day = 990 / 60
= 16.5
3x^2+1/ (1-x) (x+3) you have to simplify the expression
If it took 8 minutes and 36 seconds, 8 x 60 is 480 and 480 + 36 is 516
So the answer is 516 seconds
Answer: Absolute Value
Step-by-step explanation:
The | | is a symbol for absolute value. This signifies that the number inside would be positive. Now, this doesn't mean it will always be a number inside absolute value bars. It can also be expressions.
<u>Examples:</u>
|1|: Even though the number inside is a positive 1, we know that it cannot be negative under any circumstances. The only exception would be if there was a negative sign on the outside of the absolute value.
|-1|: We see that there is a -1 in the absolute value. This means that it is actually a 1, not -1. The absolute value is what makes everything inside positive.
|1-5|: To solve this, we know that 1-5=-4. Without the absolute value, the answer -4 would be correct. In this case, we have absolute value, so the answer is actually 4.
|x+2|: x+2 can easily be negative. This would happen is x was a negative number that is smaller than -2. x+2 can also be positive, but the absolute value guarantees that the ending result must be positive.
