Angle B is the linear pairs with 60°, so the size is 180-60=120°
Angle ABC is the linear pair with 120°, so the size is 180-120-60°
Angle A corresponds to angle 60°, so they are equal
Angle BAC is the linear pair with angle A and angle 70°, so 180-(60+70)=50°
Angle ACB is 180-(50+60) = 70°
The coefficient of x is 3.
because this is what x is being multiplied by
Answer:
0.03
Step-by-step explanation:
.25% for the tails times .5 for the odd number on the dice times 0.25 for the clubs because it is a 13/52 chance you will pull a clubs and put that all together and you get 0.03125 simplified and you get 0.03
Let x represent the speed of of boat.
We have been given that the river current is 3 miles per hour.
The speed of boat upstream will be 
.
The speed of boat downstream would be 
.
We have been given that you travel 2 miles downstream to a marina for supplies, and then you travel 3 miles upstream to a dock.
We can represent this information in an equation as:
Since the speed of the boat is 18 miles per hour, so we will substitute 
in above equation and solve for time.
Since time is in hours, so let us convert our given time in minutes.
1 hour = 60 minutes.
Rounding to nearest tenth of minute.
Therefore, it will take approximately 17.7 minutes for the boat to take the trip.
