Answer:
henc X = 30°
Step-by-step explanation:
here is the proof
when X=30° then
sin2x = sin2×30
=sin 60°
= √3/2
or else,
putting value of X = 30° then
sin2x= 2sinxcosx
= 2×sin30°×cos30°
=2×1/2×√3/2
= 2√3/4
= √3/2
hence proved sin2x= √3/2.
Answer:
11/12
Step-by-step explanation:
(1 1/10)/(1 1/5) = 1.1/1.2 = 11/12
__
You can also work this using improper fractions:
(1 1/10)/(1 1/5) = (11/10)/(6/5) = 11/10×5/6 = (11×5)/(6×10)
= (11×5)/(6×2×5) = 11/(6×2) = 11/12
Answer:
Step-by-step explanation:
The sale price = Initial Cost - 15% of the initial Cost
The sale price = 1250 - 15/100 * 1250
The sale price = 1250 - 187.5
The Sale Price = 1062.5
Now you add on the sales tax
Cost with Sales Tax = 1062.50 + 6.5/100 * 1063
Cost with Sales Tax = 1062.50 + 69.06
Cost with Sales Tax = 1131.56 dollars.
66 is 15% of what amount....
66 = 0.15x
66/0.15 = x
440 = x......so $ 66 is 15% of $ 440
