Answer:
d
Step-by-step explanation:
I took the test
(x+y) / 2 =7
multiply both sides by 2
x+y=14
3x=.5y
divide both sides by .5
6x=y
plug 6x in for y
x+(6x)=14
simplify
7x=14
divide both sides by 7
x=2
Answer:
47.1 % > 47%
Step-by-step explanation:
47.1% even if its a small amount, has a larger value than 47%.
Sin θ=sqrt(1-<span>cos^2 θ)
</span>sin θ=sqrt[1-(5/13)^2]
sin θ=sqrt[1-(5)^2/(13)^2]
sin θ=sqrt[1-25/169]
sin θ=sqrt[(169-25)/169]
sin θ=sqrt(144/169)
sin θ=sqrt(144)/sqrt(169)
sin θ=12/13
Answer: Second option 12/13
