1. A pentagonal pyramid has 6 faces, 10 edges, and 6 vertices
2. The polygons you would need to construct a pentagonal pyramid are a triangular or rectangular pyramid. Or probably just a triangle and a pentagon (I’m not sure, hope I helped)
Answer:
Force required, F = 20 pounds
Step-by-step explanation:
We have given,
force needed to stretch a spring , F = 12 pounds
Stretched length, x = 9 inches
Since, spring force formula can be given as: F = kx
i.e 12 = k · 9
or k = 
= 4/3
Now we need to find force for the stretch length = 15 inches
i.e F = kx , here x =15inches , k = 4/3 and F= ?
or F = (4/3) · 15
or F = 20 pounds
Hence force required, F= 20 pounds
Answer:
The inequality that best suits the description is choice C because Addison wants to ride her bicycle more than 80 miles this week so the inequality before 80 is used greater than>. the addition sign is put between 6m and 18 because the total of this two miles will give the total of more than 80 miles. So Addison's goal can be achieved.
the answer to other question isB. x=417.6
0.5x= 287- 78.2
= 208.8
x= 208.8÷5
x= 417.6
