Answer:

Number of boys is 9

Step-by-step explanation:

Hint: number of girls added to number of boys must equal 27

27/3 = 9

boys: girls ratio is 1:2, so boys constitute 1/3 of the class

boys -> 1 x 9 = 9

girls -> 2 x 9 = 18

(to check, 9 + 18 = 27. If solution is still unclear, try drawing a pie of 3 equal components to represent a 1:2 ratio of slices)

Please help it’s finding sin C , cos C and tan C

Aloiza [94]

The given triangle has a right angle.

We use the mnemonics SOH-CAH-TOA.

1i) $\sin C =\frac{Opposite}{Hypotenuse}$ , $\implies \sin C =\frac{30}{34}$ , $\implies \sin C =\frac{15}{17}$

ii) $\cos C =\frac{Adjacent}{Hypotenuse}$ , $\implies \cos C =\frac{16}{34}$ , $\implies \cos C =\frac{8}{17}$

$\tan C =\frac{Opposite}{Adjacent}$ , $\implies \tan C =\frac{30}{16}$ , $\implies \tan C =\frac{15}{8}$

2. We want to find the hypotenuse.

We know an angle to be 23 degrees.

We were also given the side opposite to this angle to be 1200km.

Therefore we use the sine ratio.

Answer:

35/132.

Step-by-step explanation:

There are a total of 12 balls. So:

Prob(First is green) = 5/12.

After the first selection there are 11 balls left.

Prob(The second is red) = 7/11.

The required probability = 5/12 * 7/11

= 35/132.

Note: the probabilities are multiplied because the 2 events are independent.

Answer:

56.52 units²

explanation:

We should know circle's area: πr²
Then the semi circle shall have half area, so formula: (1/2)πr²

Steps:

Using the formula:

→ (1/2)πr²

→ (1/2)(3.14)(6)²

→ 56.52 units²
