−6⋅(−7)⋅(−8)⋅0
−3⋅(−2)⋅(−4)⋅(−7)
4⋅(−9)⋅(−3)⋅(−1)
Answer:
4⋅(−9)⋅(−3)⋅(−1) product is negative,
Step-by-step explanation:
Given : Numbers .
To find : Which product is negative.
Solution : We have given expression with positive sign and negative sign.
By the integer rule : When we multiplied the even number of negative it become positive .
Example: -a * - b = ab.
When we multiplied the odd number of negative it become negative .
Example: -a * - b* -c = - abc.
This expression have −6⋅(−7)⋅(−8)⋅0 have 3 negative sign but it has 0 so, this expression would be zero.
Then only this 4⋅(−9)⋅(−3)⋅(−1) expression have 3 negative sign
So, its product would be negative.
Therefore, 4⋅(−9)⋅(−3)⋅(−1) product is negative,
The negative answer is the last one, 4⋅(−9)⋅(−3)⋅(−1)
positive times a negative = a negative
negative times a negative= a positive
a positive times a negative= a negative
Based on the number of degrees that 60 minutes is, we can infer that 20 minutes will be 120°.
A total revolution around a clock is 360° and this translates to 60 minutes.
This means that every minute is:
= Number of degrees in total / Number of minutes in revolution
= 360 / 60
= 6° per minute
If there are 20 minutes, the number of degrees is:
= 6 x 20
= 120°
In conclusion, 20 minutes on the clock is 120°.
