Answer:

$2.40

Step-by-step explanation:

We know that the sales tax is 8% , we also know that we want to buy two t shirts that cost $15.00 each.

So first, look at what we are purchasing, two t-shirts costing 15.00 dollars each.

Since we are buying two, multiply $15 by 2,

==> $30.00 dollars

And since the sales tax is 8%, to find how much we will pay will mean to multiply the amount by the percent,

30 * 8%

==> $2.40 dollars

You will pay $2.40 dollars in tax

The answer to your question is:

Step-by-step explanation:

Q1. They are vertical angles, so they measure the same

[2(x + 10)] = (3x - 30)

2x + 20 = 3x -30

2x - 3x = -30 - 20

- x = - 50

x = 50

Q2. They are also vertical angles, so they measure the same.

[6(x - 2)] = 3x + 30

6x - 12 = 3x + 30

6x - 3x = 30 + 12

3x = 42

x = 42/3

x = 14

∠DHG = 6(14 - 2)

∠DHG = 6(12)

∠DHG = 72

It is reported in USA Today that the average flight cost nationwide is $445.99. You have never paid close to that amount and you

nlexa [21]

Answer:

$H_0$ : $\mu \leq 445.99$

$H_a$ : $\mu > 445.99$

Step-by-step explanation:

It is given the average cost of the flight nationwide is $ 445.99

I wanted to $\text{perform the hypothesis test}$ to determine that the true average is greater than $ 445.99

Let the hypothesis that the true average is actually greater than $445.99

Therefore,

the $\text{null hypothesis}$ for the test is :

$H_0$ : $\mu \leq 445.99$

And the alternate hypothesis is :

$H_a$ : $\mu > 445.99$

Answer:

(a) Arts take longer

(b) By 2/9 hours

Step-by-step explanation:

Given

Arts = four over nine hours

Maths = two over nine hours

Solving (a): Which takes longer?

First, represent both as fraction

$Arts = \frac{4}{9}\ hours$

$Maths = \frac{2}{9}\ hours$

Convert fraction to decimal

$Arts = \frac{4}{9}\ hours$

$Arts = 0.444\ hours$

$Maths = \frac{2}{9}\ hours$

$Maths = 0.222\ hours$

By comparison:

$0.444 > 0.222$

Hence, Arts take longer

Solving (b): How much longer?

To do this, we calculate the difference.

$Difference = Arts - Maths$

$Difference = \frac{4}{9} - \frac{2}{9}$

Take L.C.M

$Difference = \frac{4 - 2}{9}$

$Difference = \frac{2}{9}\ hours$
