If you “unfold” the wrapping paper around this triangular prism, you have
2 triangles
Base 40, to find the height(dotted perpendicular line segment)
a^2 + b^2 = c^2. ... 20^2+ b^2 = 29^2 … 400+ b^2 = 841
- 400. -400
b^2 = 441 … b=21 this is height
1/2(40)(21) = 420 + 420
3 rectangles
Two are 70x29 = 2030 +2030
One is 70x40 = 2800
Add all 5 numbers:
420
420
2030
2030
+ 2800
7700
A quadrilateral I believe.
Answer:
WX = 7.9
Step-by-step explanation:
By applying tangent rule (law of tan) in the given right triangle WXY.
tan(W) = 
tan(27)° = 
0.509525 = 
WX = 
WX = 7.85
WX ≈ 7.9
Therefore, length of side WX is 7.9 units.
N = 1 corresponds to day 1
n = 2 corresponds to day 2
...etc etc...
n = 21 corresponds to day 21
Plug in n = 21
a_n = 100 + (n-1)*4
a_21 = 100+(21-1)*4 ... replace every n with 21
a_21 = 100 + 20*4
a_21 = 100+80
a_21 = 180
Answer: C) 180 yards
Answer: $9900
Explanation:
Commission = 6% x $165000 = 0.06 x 165000 = $9900
