A video controller cost $39. If a 6.75% sales tax is added, what is the total cost?

A. $2.63
B. $28.95
C.$41.63
D. $45.75

Answers

the correct answer is C

The total cost of the video controller is $41.63.

The correct option is C.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

A video controller cost $39.

If a 6.75% sales tax is added,

that means,

6.75% of 39,

= 6.75 x 39 / 100

= 2.6325 taxed amount.

The total cost = 39 + 2.6325 = 41.63.

Therefore, $41.63 is the total cost.

Would you please help me solve for x it should be a degrees but I’m not sure what it is

Answers

Answer:

x=15º

Step-by-step explanation:

A triangle's angles add up to 180º.

∠A=30º

∠C=180º-45º

∠B=xº

To find ∠B we have to first find ∠C.

Since ∠C does not have an angle, knowing that a straight line is 180º we can subtract it from 45º to find ∠C.

180-45=135

∠C=135º

Now add ∠A and ∠C.

30+135=165

Subtract the sum from 180º

180-165=x

x=15º

Hope this helps :)

g(- 1) = -2

Step-by-step explanation:

Given the rational function, [tex]g(x) = - \frac{21 + x}{10}[/tex]:

In order to evaluate and find the value of g(-1), simply substitute the input value into the given function.

[tex]g(x) = - \frac{21 + x}{10}[/tex]

[tex]g(-1) = - \frac{21 - 1}{10}[/tex]

[tex]g(-1) = - \frac{20}{10}[/tex]

g(-1) = -2

Therefore, the output value when g(- 1) is: g(- 1) = -2.
