6 0

Answer:

Step-by-step explanation:

\frac{(1-cosA)^2+sin^2A}{sinA(1-cosA) }=\frac{1-2cosA+cos^2A+sin^2 A}{sinA(1-cos A)}

=\frac{2-2cos A}{sinA(1-cosA)}

=\frac{2(1-cosA)}{sinA(1-cosA)}=\frac{2}{sinA}=2cscA

Answer: 4/5

Step-by-step explanation:

--------------------------------No of vehicles involved

Did alcohol play a role - - 1 - - - - - 2 - - - - - 3

Yes---------------------------- 60 - - - - 110 - - - 30=200

No - - - - - - - - - - - - - - - - 40 - -- - 215 - - - 45 =300

- - - - - - - - - - - - - - - - - - 100 - - - - 325 - - - 75

What proportion of accidents involved more than one vehicle;

Total accident = (100 + 325 + 75) = 500

Number of accidents involving more than one vehicle = (accident involving 2 vehicles + accident involving 3 vehicles)

(325 + 75) = 400

Therefore, proportion of accidents involved more than one vehicle = (Accident involving more than one vehicle / total accidents)

= (400/ 500) = 4/5

Jonathan has a collection of 400 marbles. Blue makes up 17% of his collection,how many blue marbles does Jonathan have?
Yuki888 [10]
So percent means parts out of 100 so 17%=17/100
400 marbles
17% of 400=blue
'of' can be translated to multiply
17%=17/100
17/100 ties 400=6800/100=68
he has 68 blue marbles
