b

Step-by-step explanation:

Answer:

Step-by-step explanation:

L=2W+4

P=2(L+W), using L from above makes this

P=2(2W+4+W)

P=2(3W+4)

P=6W+8

6W=P-8

W=(P-8)/6, since we are told P=26

W=(26-8)/6

W=18/6

W=3 cm, and since L=2W+4

L=2(3)+4

L=6+4

L=10 cm

So the dimensions of the envelope with a perimeter of 26cm is 3cm by 10cm

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

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

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.

Answer:

y = 2

Step-by-step explanation:

Use the slope formula so y2-y1/x2-x1 = -6/5

so -4 - y / -2 + 7 = -6/5 so y has to be 2 so that -4-2=-6

Answer:

x = 16

Step-by-step explanation:

x

-- = 9-1 ...... first shift 1 and it will be -1

2

x = 8 ....... secondly 9-1 =8

--

2

x = 16 ..... criss cross and 2×8 = 16

there fore the value of x is equals to 16.

you can check it!

Answer:

3y - 1 = 28 / 2

3y - 1 = 14

3y = 14 + 1

3y = 15

y = 15 / 3

y = 5

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°

Answer:

g(x) = [tex]2^{x}[/tex] + 3

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here the shift is 3 units up, then

g(x) = [tex]2^{x}[/tex] + 3

Answer: 1

5+10=−20+1501+10−10=−20+150−10

Subtract the numbers

15=−20+140

15=−20+14015+20=−20+140+20

Combine like terms

35=140

35=1403535=14035

=4

Answer:

Option D, the volume is 15.625 cubes

Step-by-step explanation:

For a cube of side length L, the volume is:

V = L^3

for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:

v = (1in)^3 = 1 in^3

Then:

1 in^3 is equivalent to one small cube

Here we know that the side length of our cube is (2 + 1/2) in

Then the volume of this cube will be:

V = [ (2 + 1/2) in]^3

To simplify the calculation, we can write:

2 + 1/2 = 4/2 + 1/2 = 5/2

Then:

V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3

This means that 15.625 small cubes will fill the prism.

So the correct option is D.
