Hello!

\large\boxed{9 \%}

To find the percent tax, use the equation:

\text{ \% tax} = \frac{\text{ price after - initial price}}{\text{initial price}}

Substitute in the given values:

\text{ \% tax} = \frac{\text{ 21.80 - 20}}{\text{20}} \\\\\text{ \% tax} = \frac{1.80}{20} = 0.09

Multiply by 100 to find the percent tax:

0.09 * 100 = 9\%

Let f(x) = x - 1/x. which of the following are zeros of f(x)?
ZanzabumX [31]
I'm assuming that is f(x) = (x-1)/x
In that case, the answer would be just x = 1.

However, if the original is f(x) = x - (1/x) the answer would be x = 1 and x = -1.

It's really just a formatting thing—if the given equation is indeed f(x) = (x-1)/x then x = 1 is the answer. 

Hope this helped!! xx

Find the value of x in kite EFGH<br>​
kolbaska11 [484]

Answer:

x = 105

Step-by-step explanation:

the sum of all interior angles of any four-sided figure has 360 degrees

∡F and ∡H are equal

add all four expressions and set them equal to 360

x + (x + 5) +( x + 5) + (140 - x) = 360

combine like terms

2x + 150 = 360

2x = 210

x = 105
