James bought Nicole a pair of shoes for $54.99 and a bracelet for $21.99. He used a 15% off coupon and then paid 7.5% sales tax.

Answer:

$70.34

Step-by-step explanation:

The total before the coupon and tax is:

$54.99 + $21.99 = $76.98

Now apply the 15% coupon:

Since the total price is 100% of the price, when you apply a 15% coupon, you pay 100% - 15% = 85% of the price. We need to find 85% of $76.98

85% * $76.98 =

= 0.85 * $76.98

= $65.43

The price after the 15% coupon, but before the tax, is $65.43

Now the total $65.43 is considered 100% of the price. The tax is 7.5%.

100% + 7.5% = 107.5%

Now we find 107.5% of $65.43

107.5% of $65.43 =

= 1.075 * $65.43

= $70.34

Answer: $70.34

Ou can draw a quadrilateral with two sets of parallel lines and no right angles.

Triss [41]

I believe it would be true because you can have the first set then when you have your second set it just have to be slanted for them to all be acute & obtuse angles

Answer: See below.

Step-by-step explanation:

Let's go number by number.

Rational pretty much means you can put it into a fraction of whole numbers.

The first number is -81,572.

This number is rational because it can be put into a fraction ( $\frac{-81572}{1}$ ) that is made up of whole numbers.

The second number is $\sqrt{11}$ .

This number is irrational because it cannot be put into a fraction of whole numbers.
Keep in mind that most squareroots are irrational. Especially those that don't equal a whole number.

The third number is 5.636336333

There is a pattern so the number is rational.
Usually a pattrn means it can be put into a fraction.

The fourth number is $\sqrt{16}$ . This equals 4 if you solve it out.

Since we just get 4, that certainly can be put into a fraction of whole numbers, so this is rational.

What is the answer to 6x–2x+8=20

11111nata11111 [884]

Answer:

x = 3

Step-by-step explanation:

First, simplify by subtracting 2x from 6x:

6x - 2x + 8 = 20

4x + 8 = 20

Then, solve for x:

4x + 8 = 20

4x = 12

x = 3

So, the answer is x = 3
