Step-by-step explanation:up your as
Answer:
Equation of line l,
3x-4y=1/2
y=3/4x-1/2
we get,
slope of line l =3/4
Equation of line m,
x-5=2y
y=1/2-5/2
Hence slope of line m=1/2
Slope of line l is not equal to slope of line m. Hence the line are not parallel.
Slope of line l* slope of line m ,
(3/4)*(1/2) =3/8
Since the product of slope of line l and the slope of line m is not equal to -1, the lines are not perpendicular.
Hence the lines are neither perpendicular nor parallel..
21. Smith received 60% of the votes
Murphy received 1/3 or 33%
100% - (60% + 33%) = 100 - 93 = 7%......so where is the other 7% of the votes. The vote total should equal 100%
22. Food : 500/2000 reduces to 1/4......or 25%......or 0.25
Rent : 1200/2000 reduces to 3/5....or 60% ...or 0.6
Transportation : 300/2000 reduces to 3/20...or 15%..or 0.15
23. sum of the rows:
Food + rent + trans = 1/4 + 3/5 + 3/20 = 5/20 + 12/20 + 3/20 = 20/20 = 1
Food + rent + trans = 25% + 60% + 15% = 100%
Food + rent + trans = 0.25 + 0.6 + 0.15 = 1
The sums should all equal because the percent, decimals, and fractions are all the same, just in a different form
24. 14.5% = 0.145 = 145/1000 = 29/200
14.5 = 14.5 = 14 1/2 = 29/2
14.5% is less then 1
14.5 is greater then 1
