Assuming that the number cube is 6 sided
6 is one number in a 6 sided cube, so the probability is: 1/6
heads is one side of the coin, with two in all: 1/2
Multiply the two fractions together
1/6 x 1/2 = 1/12
1/12 is your probability
hope this helps
Answer:
v ≈ 8.5 km/h
Step-by-step explanation:
Since the diameter of the wheel is 3 m the radius will be r = 1.5 m.
Use the radius of the water wheel to find it's circumference C:
[set r = 1.5 m]
⇒ 
⇒ 
m
One revolution of the water wheel corresponds to 
meters so the angular velocity 15 rmp (revolutions per minute) corresponds to:
= 
/min
Using this result, the speed of the river in kilometers per hour will be:
× 
× 
⇒ 
⇒ 
≈ 
km/h
Answer:
x=3
Step-by-step explanation:
You add the eight to both sides, leaving x on the left and making the -2 a 6 on the right.
Now you have x= 3x-6
Add the six to the right, giving you 6+x=3x
Subtract the x from the left and right. you get 6=2x
Divide 6 by 2 to get x.
Answer:
maria will run 1.75 more miles than her goal
Step-by-step explanation:
If you multiply 2.75 to 7 days you will get 19.25. And if you subtract it by 17.5(because that's her goal) you will get 1.75.
So the answer to this question would be:
Maria will run 1.75 more mile than her goal.
