Let the boat speed in still water be b.
Let the current speed be c.
The speed going upstream is 20/4 = 5 mph.
The speed going downstream is 32/4 = 8 mph.
b - c = 5 ........(1)
b + c = 8 .......(2)
Adding equations (1) and (2) we get:
2b = 13
b = 13/2 = 6.5
Plugging in the value for b into equation (1) we find c = 1.5.
The boat speed in still water is 6.5 mph and the current speed is 1.5 mph.

Answer:
x = 5, y = 5
Step-by-step explanation:

Answer:
1. 702 square centimeters
2. m∠YWX = 63°
Step-by-step explanation:
1.
The total surface area is area of all the sides.
- There are 2 triangles (slanted side) with base 14 and height 11. Thus area would be

- There are 2 triangles (another slanted side) with base 10 and height 12. Thus area would be

- There are two rectangles with base 10 and height 6. Thus area would be

- There are two rectangles with base 14 and height 6. Thus area would be

- The bottom is a rectangle with area 10 * 14 = 140
Adding all these up 154 + 120 + 120 + 168 + 140 = 702 centimeters square.
2.
Angle WYX is equal to 46° (vertical angles are equal).
Now looking at triangle XWY, we know all three angles will add up to 180°. Given x =71° and Y = 46°, we can figure out W (Angle YWX)
71 + 46 + Angle YWX = 180
Angle YWX = 180 - 71 - 46 = 63°
Second answer choice is correct.
