Answer:
Option A - Permutation; number of ways = 210
Step-by-step explanation:
Given : At a competition with 7 runners, medals are awarded for first, second, and third places. Each of the 3 medals is different.
To find : How many ways are there to award the medals?
Solution :
There are 7 runners but medals are three.
The first runner up got first medal as one is locked.
The second runner up got second medal as second is locked.
The third runner up got the third medal.
So, There is a permutation.
Number of ways to award the medals is
We know,
Substitute the values,
Therefore, Option A is correct.
Permutation; number of ways = 210

Answer:
I'm not sure what you want me to answer from this, so I solved for every variable:
Angle A: 83°
Side b: 6.29
Side c: 5.8
Step-by-step explanation:
-----Angle A:
Since the sum of the interior angles of a triangle ALWAYS equal 180°, we can solve for angle A as follows:
-----Side b:
Here, we use the sin rule for finding sides, since we know all of the angles as well as one side:
-----Side c:
Simple just decide pie by the universe multiplied bye the square rout of a f1 race car most likely leading too yes
First, let's fine the decimal of each fraction.
-5 Divided By 6 = -0.83333333333
17 Divided By 18 = 0.94444444444
-2 Divided By 9 = -0.22222222222
-5/6 - 17/18 - (-2/9) = -1.55555555556
