200,000 + 80,000 + 3,000 + 900 + 80
Answer:
1320
Step-by-step explanation:
This is a simple permutation.
Since you start with 12 people and there are 3 winners, after every winner the number pf people available to win decrease.
First, there are 12 people, then after the first win there are 11 people, and after the 2nd win, for the third win the there are 10 people.
Thus, to find the total number of combinations, you multiply:
12*11*10=1320
Thus, there are 1320 possible combinations
Answer:
Step-by-step explanation:
Cross multiply, isolate the variable, and divide by the coefficient to solve.
Plug back in to check.
A right triangle has 1 90 degree angle and the interior angles must add to 180.
3(x+8)+x+90=180
3x+24+x+90=180
4x+114=180
4x=66
x= 16.5
Plug this value in to find the last angle
16.5+90+x=180
106.5+x=180
x=73.5
Final answer: 73.5 degrees and 16.5 degrees
