10% raise
hmm
find his amount earned first
15.5 per hour
15.5 times 35=542.5
10% more is times 1.10
542.5 times 1.10=596.75
5% is deducted for tax
100-5=95
596.75 times 0.95=566.9125
now add 200
766.9125
round
$766.91 is his check

Answer:
1. 792 2. 20. 3. 126. 4.1995840
Step-by-step explanation:
Use the formula C(n,r)= n!/ r/ (n-r)! where n is total quantity of varieties and r is the quantity uou should choose.
1) n=12 (total quantity); r= 7
C(12,7)= 12!/(7! *(12-7)!)= 8*9*10*11*12/ (5*4*3*2)= 8*9*11= 72*11= 792
2) n=6 r=3
C(6,3)= 6!/ (3! * (6-3)!)= 6!/ (3!)^2= 4*5*6/ 3*2= 20.
3) C(9,5)= 9!/ (5!*4!)= 6*7*8*9/ (4*3*2*1)= 2*63= 126
4) You need to choose the whole set which consists of three components that has been defined. Multiply previous results
792*20*126= 1995840.
It not a right angle or an obtuse angle, so it has to be a acute angle, so angle x would be 50 or 55 degrees.
right angle:90 degrees.
obtuse angle: greater than 90 less than 180.
acute angle: less than 90 degrees.
