Answer:
1240.4 mm²
Step-by-step explanation:
SA of Pentagonal pyramid:
(as)(5/2) + (sl)(5/2)
↑ ↑
base area lateral area
_____________________
a: apothem (in-radius) length, s: side length.
l: slant height.
______________________
Since we are already given the base area which is 440.4 mm². All we need to do is find the lateral area and add both areas together.
Given that the triangular face of the lateral part has a side/base length of 16mm, and a 20mm slant height.
A triangle has an area of ½bh and since there are 5 of these faces total, (5)(½bh) = (5/2)(bh). In a three dimensional perspective, b will be s and h will be l so (sl)(5/2).
With this information the surface area is:
(16)(20)(5/2)mm + (440.4 mm²) →
800 mm² + 440.4 mm² =
1240.4 mm²
Answer:
I wanna say that,
Time to Climb (min) <u>Dependent Variable</u>
Height (ft<u>)</u> <u>Independent Variable</u>
Hope this helps, let me know if I'm wrong.

(3,1)(0,-1)
slope = (-1 - 1) / (0 - 3) = -2/-3 = 2/3...a parallel line will have the same slope
y = mx + b
slope(m) = 2/3
(-3,0)...x = -3 and y = 0
now we sub and find b, the y int
0 = 2/3(-3) + b
0 = -2 = b
2 = b
so ur parallel equation is : y = 2/3x + 2
15 times 6 is 90
I hope it’s right a million apologies if I’m wrong
