A compact disc player costs £50 plus 17 1/2 % VAT.

Calculate the total cost of the compact disc player.

Answers

Answer:

£58.75

Step-by-step explanation:

Given data

Cost = £50

VAT= 17 1/2%= 17.5%

Let us find the amount of the VAT

=17.5/100*50

=0.175*50

= £8.75

Hence the total cost of the compact disk is

=50+ 8.75

=£58.75

11. A company plans to have coffee mugs produced with the company logo on them. The cost of each
depends on the number of mugs that are ordered and is modeled by y =
0.0001x2 0.1x + 30, where x
is the number of mugs ordered and y is the cost (in dollars). What is the minimum cost of each mug?

Answers

Answer:

$5

Step-by-step explanation:

The cost of each mug  depends on the number of mugs that are ordered and is modeled by :

[tex]y =0.0001x^2+ 0.1x + 30[/tex] ...(1)

We need to find the minimum cost of each mug.

For minimum cost, dy/dx = 0

So,

[tex]\dfrac{d(0.0001x^2- 0.1x + 30)}{dx}=0\\\\2x(0.0001)-0.1=0\\\\0.0002x=0.1\\\\x=\dfrac{0.1}{0.0002}\\\\x=500[/tex]

Put the value of x in equation (1).

[tex]y =0.0001(500)^2- 0.1(500) + 30\\\\y=5[/tex]

So, the minimum cost of each mug is $5.

Answers

Answer:

p=-5

Step-by-step explanation:

have a lovely day!!

P= 15

That is bc if +19 has a + u make it - so then u subtract.

So 19-14=15 to find the p.

P=15

If the 19 was -19 instead of +19 then u would do.

19+14= 43. Which would then be.

P=43.

Doubt that he is.

Step-by-step explanation:

Two types of tickets were sold for an upcoming concert: adult tickets and child tickets. In total, there
were 175 adult tickets sold and 103 child tickets sold. There was a total of $13796 in ticket sales. The
Jones family bought two adult tickets and two child tickets and spent a total of $184. How much does an
adult ticket cost and how much does a child ticket cost?

Answers

Answer:

Adult ticket is $60

Child ticket is $32

Step-by-step explanation:

Let x = price of adult ticket

     y = price of child ticket

(1)    175x + 103y = 13796               (2)    2x + 2y = 184

                                                                 x + y = 92

                                                                       y = 92 - x

      175x + 103(92 - x) = 13796

      175x + 9476 - 103x = 13796

       72x = 4320

           x = 60                                                  y = 92 - 60

                                                                        y = 32

$1.50 per game.
Part A
Write a system of equations to
represent the situation, using g for
number of games and c for cost.

Answers

Answer:

It should be $10.50

Step-by-step explanation:

We just need the equations to equal the same, which is y.

5+1.10x=y

3+1.50x=y

5+1.10x= 3+1.50x

Lets get x by itself by subtract 3 from both sides.

2+1.10x= 1.50x

Now subtract 1.10x from both sides.

2= 0.4x

Now divide each side by 0.4

5=X

So, at 5 games they're the same cost. Let's find the cost.

5+1.1(5)= 5+5.5=10.50

3+1.5(5)=3+7.5= 10.50

In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,

which law would you use? Laws of Sines or Laws of Cosines? and why?

Answers

Answer:

We would use the Law of Cosines to solve the question.

m∠ W = 121.8°

Step-by-step explanation:

In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,

which law would you use?

The Law we would use to find find m∠W is the Law of cosines, this is because in the question above we are given 3 known sides of a triangle and we are asked to find an unknown angle.

Law of cosines when we are to find an unknown angle =

m∠ W = arc cos [u² + v² - w²/ 2uv]

m∠ W = arccos [ 20² + 47² - 60²/ 2 × 20 × 47]

m∠ W = 121.81159°

Approximately = 121.8°

B. the mean is less than the median
C. the mean is the same as the median
D. the data set does not have a median

Answers

Answer:

C

Step-by-step explanation:

Normal distribution has a unique characteristic of having equal mean and median values. If mean was higher than median, then the distribution would be positively skewed. Mean lower than median would appear in distributions negatively skewed. Each data set has a median value.

p(blue or red) = 0.52 = 52%

Step-by-step explanation:

total number of marbles = 7 + 10 + 14 + 19 = 50

number of blue marbles = 7

number of red marbles = 19

number of blue or red marbles = 7 + 19 = 26

p(blue or red) = 26/50
