Answer:
LN = 64 units
Step-by-step explanation:
Given M lies on LN, so LN = LM + MN --------------(1)
LN = 12x + 16
LM = 10x + 8
MN = 5x - 4
Substituting the values in equation 1, we get:
12x + 16 = (10x + 8) + (5x - 4)
12x + 16 = 15x + 4
15x - 12x = 16 -4
3x=12
Therefore x=4
LN= 12(4) + 16 = 64 units
The problem given above can be solved through the concept of permutation because of the importance of the arrangements. This may be solved through calculators directly by keying in,
10P5
That is, the permutation of 10 taken 5. The answer to this permutation is 30,240.
80 c, 80%, 80/100, .80
$1.20, 120%, 120/100, 1.2
$1.60, 160%, 160/100, 1.6
$1.28, 128%, 128/100, 1.28
Same solution.
volume = 1/3(8x6)(5) = 16x5 = 80cm^3
answer: 80cm^3
