Answer:
3.245
Step-by-step explanation:
2.22+1.51+1.86+2.06+3.48+4.57+3.27+5.40+5.45+4.34+2.64+2.14 then divide by twelve because that is the number of months :))))
Answer:
Step-by-step explanation:
- radius (r) = 3 in (Given)
- height (h) = 8 in (Given)
- It is given that: all the three cylinders are identical, means their radii and heights are equal.
- Thus, the volume of composite figure will be equal to three times the volume of single cylinder.
Answer:
joint variation means L (safe load) is directly proportional to both w and d2
inverse proportionality means L = k/l
So the equation is:
L = k(wd2/l)
You are given:
w = 6 in
d = 5 in
l = 12 ft
L = 7666 lbs
7666 = k(6*52/12)
Solve for the constant, k.
7666 = k (6*25/12)
7666 = k (150/12)
7666 = k (12.5)
613.28 lbs/(ft.in3) = k
Use this k-value to solve for L in the last part of the question.
What safe load, L would a beam 3 in. wide, 7 in. deep and 15 ft long of the same material support? (Round off your answer to the nearest pound.)
w = 3 in
d =7 in
l = 15 ft
k = 613.28 lbs/(ft.in3)
Final Safe load = 6010.144 lbs *** Edited for clarity and to fix a multiplication erro
