Answer:
StartFraction StartRoot 3 EndRoot Over 3 EndFraction
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
we know that
In the right triangle XYZ
---> adjacent side divided by the hypotenuse
substitute the values

Remember that

so
substitute



step 2
--> opposite side divided by the hypotenuse
substitute the values

Remember that

so


step 3
--> opposite side divided by adjacent side
substitute the values
Simplify

so
StartFraction StartRoot 3 EndRoot Over 3 EndFraction
A = P(1 + rt)
1565 = 625(1 + (0.047)(t))
2.504 = 1 + 0.047t
1.504 = 0.047t
t = 32
I hope this is correct! (Sorry I haven't done simple interest in a while.)
280 students have a total of 560 points
There 60 more boys(x+60) complete than girls(x)
2*(x+60)+2*x= 560
number of girl =x =110
girl point =110*2= 220
Pretty sure the answer is k
