probability of you performing first is 1/13
after your team performs there are 12 teams left, so chance of the other team performing next is 1/12
chance of both happening = 1/13 * 1/12 = 1/156
Answer: 5/2 and 25/4
Step-by-step explanation:
6x5=30
6x2=12
...
say these were perfect squares,
12x12= 144
30x30= 900
900/144 = 25/5
The equation of the area of a triangle is Area=Length×Width. We know area=256.5 and length is 18. So now we know 256.5=18×width. We then divide 256.5÷18 to get the width. The width is 14.25. Perimeter=legth+length+width+width. If width is 18 and length is 14.25 then we add up all 4 sides. 18+18+14.25+14.25=64.5. 64.5 is the perimeter
The two given angles are vertical angles and equal each other:
3x + 50 = 6x -10
Now solve for x:
Subtract 3x from both sides:
50 = 3x -10
Add 10 to both sides:
60 = 3x
Divide both sides by 3
X = 20
You would use the Pythagorean there on which is a^2+b^2=c^2, from there you plug int what they gave you and solve for b, and b=12
