Answer:
If Andrew works for 30 for $4 he will have a total wage of 30×4=$120
And gets additional $5for every hr worked beyond 30hrs in that week
So he gets a total of 5(x-30)
So if he works for 40hrs he gets a total wage of
5(40-30)=50
120+50=$170
If he works for 50 hours he gets Total wage of
5(50-30)=100
120+100=$220
Answer:
The price after the discount would be $315.
Angle D is 180° -75° -45° = 60°. Drawing altitude MX to segment DN divides the triangle into ΔMDX, a 30°-60°-90° triangle, and ΔMNX, a 45°-45°-90° triangle. We know the side ratios of such triangles (shortest-to-longest) are ...
... 30-60-90: 1 : √3 : 2
... 45-45-90: 1 : 1 : √2
The long side of ΔMDX is 10√3, so the other two sides are
... MX = MD(√3/2) = 15
... DX = MD(1/2) = 5√3
The short side of ΔMNX is MX = 15, so the other two sides are
... NX = MX(1) = 15
... MN = MX(√2) = 15√2
Then the perimeter of ΔDMN is ...
... P = DM + MN + NX + XD
... P = 10√3 +15√2 + 15 + 5√3
... P = 15√3 +15√2 +15 . . . . perimeter of ΔDMN
