Correct answer is A
y = k\(\sqrt{x}\) when y = 1, x = 4
k = \(\frac{y}{\sqrt{x}}\)
= \(\frac{1}{\sqrt{4}}\)
= \(\frac{1}{2}\)
= 0.5
\(\frac{1}{8}\)
\(\frac{1}{3}\)
\(\frac{3}{8}\)
\(\frac{3}{5}\)
Correct answer is C
ratio of boys to girls = 5:3
total = 5 + 3 = 8
Pr(girl) = \(\frac{3}{8}\)
If tan y = 0.404, where y is acute, find cos 2y
0.035
0.719
0.808
0.927
Correct answer is B
tan y = 0.404; y = tan-1 0.0404(tables);y = 22o
cos 2y = cos 2(22o); cos 44o
= 0.719
2\(\frac{1}{2}\)
6\(\frac{1}{2}\)
15\(\frac{3}{8}\)
17\(\frac{1}{2}\)
Correct answer is A
\(\frac{40}{100} \times 50\)kg = 20kg
\(\frac{1}{8}\) of 20kg for cake; \(\frac{1}{8}\) x \(\frac{20}{1}\)
= 2\(\frac{1}{2}\)kg
If 30% of y is equal to x, what in terms of x, is 30% of 3y?
\(\frac{x}{9}\)
\(\frac{x}{3}\)
x
3x
Correct answer is D
If 30% of y = x, then 30% of 3y = 3x
