8.975 is the correct answer
Answer:
Step-by-step explanation:
He make 420 dollar off them 70 shirts
The model is 1:50 so take 11/5 and multiply it by 50 and you get 110, so the window is 110 inches long
The modulus of complex number can be computed with this equation:
|z|=sqrt(Re(z)^2+Im(z)^2)
z = -2-6i
Re(z)=-2, so Re(z)^2=4
Im(z)=-6, so Im(z)^2=36
|z|=sqrt(36+4)=sqrt(40)=6.3
