Answer:
5x-5-3-1=-12
5x-9=-12
5x=-12+9
5x=-3
x=-3/5
Step-by-step explanation:
The area of the spinning board is divided into 10 equal sections.
Probability in this case will be = Area of favorable outcome/Total Area
Let the total area be A.
Area of each section will be A/10
So probability of landing on 3 will be = (A/10) / A = 1/10
So the correct answer will be option C
What do you mean this sentence?
the time a pump takes to drain the pool varies inversely with the power in watts of the pump,
The meaning would be : if we have a power in watts greater the time to drag the pool will be less because the relation between power and time is inverse.
40 watts--------------5 hours)
100 watts------------ x
because the relation between power and time is inverse, we multiply directly.
40 watts(5 hours)=100 watts x
x=(200 watts hours) / 100 watts=2 hours.
Answer: the time would be 2 hours. (the new pump is faster)
Here is the work to go with the answer it is hard to completely type out hope it helped!
It will take 90 minutes which is also an hour and a half.
