The product of 9 and 12 is 108
Step-by-step explanation:
using trigonometric ratios,
sin theta= opposite ÷ hypoteneus (h)
sin 45°= 3 root 2 ÷ h
1/root 2= 3 root 2 ÷h
h= 3× root 2 × root 2
= 3×2
= 6 unit
R=8+I
S=4R
R+I+S=112
R+R-8+4R=112
6R=120
R=20
So therefore, Ruby worked 20 hours, Svetlana worked 80 hours, and Isaac worked 12 hours.

Answer:
I don't even know what that is srry tho.
Step-by-step explanation:
Let her score on her math test be y and the number of hours a week that she plays video games be x,
y = k/x
73.6 = k/10
k = 736
y = 736/x
y = 736/8
y = 92
She can expect a score of 92 on her math test if she plays video games for only 8 hours a week.
