Correct answer is B
Let x represent total number of pencils shared
B : S : T
2 : 3 : 5
2+3+5 = 10
\(\frac{2}{10}\) x x = 5
\(\frac{2x}{10}\) = 5
2x = 50
x = 25
Simplify \(\frac{0.026 \times 0.36}{0.69}\). Leave your answer in standard form
1.36 x 10-4
1.36 x 10-3
1.36 x 10-1
1.36 x 10-2
Correct answer is D
\(\frac{0.026 \times 0.36}{0.69}\) = \(\frac{26 \times 10^-3 \times 36 \times 10^-2}{69 \times 10^-2}\)
= 0.01356 = 1.36 x 10-2
{1, 3, 5, 7, 9, 11, 13, 15}
{2, 3, 5, 7, 9, 11, 13}
{1, 3, 5, 7, 9, 11, 13}
{2, 3, 5, 7, 11, 15}
Correct answer is C
U = {1, 2, 3, 4, 5......14}
P = {2, 4, 6, 8, 10, 12, 14}
P' = {1, 3, 5, 7, 9, 11,13}

Correct answer is C
(2 x 4) + (3 x 4) + (4 x y) = 48
8 + 12 + 4y = 48
4y = 48 - 20
\(\frac{4y}{4}\) = \(\frac{28}{4}\)
y = 7
Calculate the perimeter of a sector of a circle of raduis 12cm and angle 60o.
(12 + 4\(\pi\))cm
(24 + 4\(\pi\))cm
(12 + 6\(\pi\))cm
(24 + 6\(\pi\))cm
Correct answer is B
Perimeter = 2r + \(\frac{\theta}{360}\) x 2\(\pi\)r
= 2(12) + \(\frac{60}{360}\) x 2 x \(\pi\) x 12
= (24 + 4\(\pi\))cm
