It would be an 8 percent discount because 115 is 92 percent of 125.
The magnitude of the vector is √(7^2+12^2)=√(49+144)=√193
The direction is α=arctan(y/x)=arctan(12/-7)≈-59.74 however this is relative to the negative x-axis so we add 180° to get the standard angle...180-59.74=120.26°
So the vector is √193 @ 120.26°
1 1/4?? because 7/4 cant be a whole number its a mixed number when simplified
1,5, and 25. 1*25=25 and 5*5=25
To solve this, set up the equation, 90% of x being .9*x=57. Then, solve for x, x=57/.9=
=6.333
