If an item is 4.75 before tax and after is 5.13 how much is the sales tax rate?
Anestetic [448]

Answer:

8%

Step-by-step explanation:

Let's say the tax percent was x%. Then, we can write the equation:

4.75 + x% * 4.75 = 5.13

Notice that both terms on the left have 4.75 so factor that out:

4.75 * (1 + x%) = 5.13

Divide both sides by 4.75:

1 + x% = 5.13/4.75 = 1.08

Subtract 1 from both sides:

x% = 0.08

Remember that % simply means "out of 100", so x% = x/100:

x/100 = 0.08

Multiply both sides by 100:

x = 8

Thus, the tax rate is 8%.

Hope this helps!

Pleaseeee! <br>I need help evaluating this:<br><br><br>Tan 2 theta-(1-tan^ 2 )=?​
andreev551 [17]

Answer:

\tan \left(2\theta\right)-1+\tan ^2\left(\theta\right)

Key:

• -\left(a-b\right)=-a+b

Step-by-step explanation:

\tan \left(2\theta\right)-\left(1-\tan ^2\left(\theta\right)\right)

-\left(1-\tan ^2\left(\theta\right)\right)=-1+\tan ^2\left(\theta\right)

=\tan \left(2\theta\right)-1+\tan ^2\left(\theta\right)
