Answer:

60 serves

Step-by-step explanation:

According to the average, Sam should be able to hit 2/5 of his serves within the service lines.

If Sam hits 150 serves, find 2/5 of 150

2/5 * 150/1 = 300/5 = 60

Sam hit 60 serves within the service line during the match.

Hope this helps :)

Cos(−θ)=√3/3, sinθ<0

Delicious77 [7]

Answer:

$\sin\theta=-\frac{\sqrt{6}}{3}$

Step-by-step explanation:

The given trigonometric equation is $\cos(-\theta)=\frac{\sqrt{3} }{3}$ .

We can either use the Pythagorean identity or the right angle triangle to solve for $\sin\theta$ .

According to the Pythagorean identity,

$\cos^2\theta+\sin^2\theta=1$

Recall that, the cosine function is an even function, therefore

$\cos(-\theta)=\cos(\theta)$

$\Rightarrow \cos(\theta)=\frac{\sqrt{3} }{3}$ .

We substitute this value in to the above Pythagorean identity to get;

$(\frac{\sqrt{3}}{3})^2+\sin^2\theta=1$

$\Rightarrow \frac{3}{9}+\sin^2\theta=1$

$\Rightarrow \sin^2\theta=1-\frac{3}{9}$

$\Rightarrow \sin^2\theta=\frac{6}{9}$

$\Rightarrow \sin\theta=\pm \sqrt{\frac{6}{9}}$

$\Rightarrow \sin\theta=\pm \frac{\sqrt{6}}{3}$

But we were given that,

$\sin\theta\:$ , so we choose the negative value.

$\Rightarrow \sin\theta=-\frac{\sqrt{6}}{3}$

The correct answer is B

Which equation shows the variable terms isolated on one side and the constant terms isolated on the other side for the

Alinara [238K]

Answer:

Step-by-step explanation:

$3x - 5 = -2x + 10$

Let's move everything with an $x$ to the left side of the equation, and everything else to the right side:

$3x + 2x = 10 + 5$

$5x = 15$

Finally, let's divide both sides by $5$ to get $x$ by itself on the left side of the equation:

$x = 3$
