You decide to go to the movies for your birthday. You need to buy 8 student tickets and 2 adult tickets. If student tickets are

Leto [7]

Answer:

$112.80

Step-by-step explanation:

You are buying 8 student tickets, each costing $10.68. Multiply 8 with 10.68:

10.68 x 8 = 85.44

You are buying another 2 adult tickets, each costing $13.68. Multiply 2 with 13.68:

13.68 x 2 = 27.36

Next, add the two costs together:

27.36 + 85.44 = 112.80

$112.80 is your total cost.

What value of x satisfies

LenaWriter [7]

Answer:

See explanation

Step-by-step explanation:

The given trigonometric equation is $cos(90-x)=-\frac{\sqrt{3} }{3}$ .

We take the inverse cosine of both sides to get:

$90-x=cos^{-1}(-\frac{\sqrt{3} }{3})$

$90-x=125$

$x=125-90$

$x=-35\degree=325\degree$ to the nearest degree

None of the options satisfies the given equation.

But if the question is actually;

$cos(90-x)=-\frac{\sqrt{3} }{2}$

Then;

$90-x=\cos^{-1}(-\frac{\sqrt{3} }{2})$ .

$90-x=210$ .

$x=-120\degree$ .

$x=360-120=240\degree$ .

In this case the answer will be B
