7.16 dpollars for one candy bar
Answer:
n=25% or 0.25
Step-by-step explanation:
865= 580(n%)+ 6(120)
865= 580 (n%) +720
865-720= 145
145= 580(n%)
divide both by 580, you get 0.25=n%
Area of the Base = 6 * side^2 / 4 * tan (180/6)
Area of the Base = 6 * 16 / 4 * 0.57735
Area of the Base = 96 / 2.3094
Area of the Base = 41.5692387633
Area of 1 Face = 2 * 6 = 12
Area of 6 Faces = 72
Total Area = 41.5692387633 + 72
Total Area = 113.5692387633
Step-by-step explanation:
a)82km into miles
Sol'n
Here,
km=82=82000miles
m=?
Now,
Miles =km×1000
=82×1000
=82000
Therefore,82000m.
Parallel: the lines have = slopes. We thus need 5/6 to equal 2/p. then 5p must equal 12, and p = 12/5. (answer)
Check: Is 5/6 = 2 / (12/5)? YES
Perp.: The lines have slopes that are negative reciprocals of one another.
Then -6/5 = 2/p, or
-6 2
---- = ----
5 p Thus, -6p = 10, and p = -5/3 (answer)
