Answer:
<h2>153 dimes.</h2>Step-by-step explanation:
1+2+3+...+17 = (17×18)/2 = (17×18)÷2 = 153 dimes.
it’s the sum of 17 terms of a geometric series.

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.
