I think that car travelled 128 km in one hour and 384km in 3 hours
The experiment probabilities are listed below:
One: 2 out of 20 = 2 / 20 = 0.1 or 10%
Four: 5 out of 20 = 5 / 20 = 1 / 4 = 0.25 = 25%
The theoretical probability of any single number is 1 out of 6 or about 17%.
The experimental probability for ones was less than and for fours it was greater than the theoretical probability.
Answer:
Step-by-step explanation:
The cat will take 0.8 seconds to catch up with the mouse
Step-by-step explanation:
Given:
The distance between the cat and the mouse = 4 feet
cat's speed = 17 feet per second.
mouse's speed = 12 feet per second
To Find:
how long will it take the cat to catch up with the mouse = ?
Solution:
We know that
distance = speed x time
Rewriting the equation for time we get
time =
now we know that distance is 4 feet
and the speed is 17 -12 = 5 feet per second
Thus the time is
= 
= 0.8 seconds
Answer:
x=20
Step-by-step explanation:
So, they are vertical angles so they would be EQUAL.
The equation you would use to solve for 'x' would be:
3x=80-x
Then, you would solve for x. First you would need to get all the x's on the opposite side of the numbers.
3x=80-x
Add x to both sides
4x=80
Then, you would have to divide on both sides.
4x=80
Divide by 4 on both sides
x=20
Then, if you need to find out what the angles would be, just plug x in.
3(20) = 60
80-(20) = 60
Hope this helped!! :)
