It is a 25% markup. This is true since if you subtract 35-28=7. Then, 7/28=0.25 and 0.25*100=25%
Answer:
√23/√45 or √23/3√5
Step-by-step explanation:
Cosine is adjacent over hypotenuse. Angle W has an adjacent side of WU(√23) and WV .You know the adjacent but not the hypotenuse, so you will use the formula a^2+b^2=c^2 to find the hypotenuse. Plug in the sides for A and B -> (√23)^2+(√22)^2=c^2. Simplify it --> 23+22=c^2 --> 45=c^2. Solve for C alone (not c^2). √45=c. Then use the cosine formula (adjacent/hypotenuse) to plug in the numbers.
Answer:
55°
Step-by-step explanation:
In the picture above.
I hope that it's a clear solution and explanation.
Answer:
The actual distance is 16 miles.
Step-by-step explanation:
In order to find this, create a proportion. On the left you should put the scale factor. On the right you should put the markers.
2.5in/10mi = 4.5in/xmi
Now cross multiply to solve.
10mi * 4.5in = 2.5in * xmi
45 = 2.5x
16 mi = x
