Answer:
Step-by-step explanation:
cos x=sin 2x
sin 2x-cos x=0
2 sin x cos x-cos x=0
cos x(2 sin x-1)=0
either cos x=0
or
2 sin x-1=0
What you would do is take the denominators and multiply them by each other, then multiply the numerators by that same number. So like 4/10 and 4/9. You would say, (denominators) 10x9=90 and (numerators) 4x9=36. So your first fraction would be 36/90. Next, you would take (denominators) 9x10=90 and (numerators) 4x10=40. So your second fraction would become 40/90. Now it's a lot easier to compare. 36/90 < 40/90 would be the answer to my problem. I hope I helped!

Answer:
567.69
Step-by-step explanation:
Let p represent the original price
The Mark up is 27%
= 27/100
= 0.27
= p + 0.27p
= 1.27p
The retail price for pants is
= 1.27(74)
= 93.98
The retail price for suit jacket is
= 1.27(325)
= 412.75
The retail price for dress shirt is
= 1.27(48)
= 60.96
Therefore the markup for a pair of pants, dress shirts and suit jacket can be calculated as follows
= 93.98 + 412.75 + 60.96
= 567.69
