First, we find the cost for 1 minute.
So, we need to divide the total costs by the total times.
$1.08 ÷ 18 minutes = $0.06

Then, we change the rate in cents per minute.
$0.06 = 6 cents per minute

Given:

ABC is a right triangle.

Opposite of C = AB = 6

Adjacent of C = BC = 8

Hypotenuse = AC = 10

To find:

The value of sin C.

Solution:

Using basic trigonometric ratio formula:

$\sin \theta = \frac{\text{Opposite of }\theta}{\text{Hypotenuse}}

$\sin C = \frac{\text{Opposite of C}}{\text{Hypotenuse}}

$\sin C = \frac{AB}{AC}

$\sin C = \frac{6}{10}

Cancel the common factors.

$\sin C = \frac{3}{5}

The value of sin C is \frac{3}{5}.

mario62 [17]
<h2>Answer:</h2>

w= -8/9

alternative form:

w= -0.8

<h2>Step-by-step explanation:</h2>

3(3w-4)=-20

distribute by multiplying the numbers in parenthesis by 3

9w-12=-20

add 12 to both sides

9w=-8

divide both sides by 9

-------------

w= -8/9
