The answer is D. 76. This is because if STR is 28 degrees, and angle STU is on a straight line, all we have to do is subtract 180-28, then divide by 2.
Answer:
100
Step-by-step explanation:
To find mean/average you add all of them together, then divide by however number there are.
So
99+88+97+107+100+109 = 600/6 = 100
You wanna get the y by itself. So you will subtract 11.9 then move it to the other side. so that is 10.5y = -11.9x +178.5. Then divide everything by 10.5. Then you get y = -11.9x/10.5+17. 11.9x/10.5 is because you cant put 10.5 into 11.9 evenly so you leave it as a division problem.
Markup = profit/ cost*100% Markup= 50 you could double check
514÷1800=0.285555
multiply the 0.285 by 100=28.55555%
