The answer is 3 diagonals
Answer:
1320 ways
Step-by-step explanation:
Here we have a situation where 3 ribbons will be awarded to 3 of the 12 contestants. We can use the permutation formula, because the order of awarding the ribbons matters.
The permutation formula is:
n = 12
k = 3
Now that we have our variables, let's plug them into the formula.
So there are 1320 different ways that the contestants will be awarded.
Answer:
Slope = ⅓
Step-by-step explanation:
Slope (m) = change in y/change in x
Using two points on the line, (-5, 1) and (1, 3),
Change in y = 3 - 1 = 2
Change in x = 1 - (-5) = 6
Slope (m) = change in y/change in x = 2/6
Slope = 1/3
We first find out time taken to travel for just 1 km
2hrs is equivalent to 120 minutes
120 km = 120 min
1 km = x (where x is the time taken to travel 1 km).
we simplify the equation by cross - multiplying the equation , so:
120 × x = 1 × 120 → 120x = 120 → x = 120/120 → x = 1
So the car covers 1km in 1 minute
For 300 km the car will take 300 × 1 minute = 300 minutes
we convert minutes to hours by dividing by 60 → 300 / 60 = 5
Therefore the car will take 5 hours to cover 300 km.
