QUESTION #5 - Consumer Math

Mathematics
1 answer:
Svetach [21]2 years ago
3 0

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

Answer:

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
