She has to pay £100.98.

Step-by-step explanation:

Given,

The cost of adult ticket = £12

The cost of child ticket = £6

10% booking fee will be added.

2% will be added if she is paying by credit card.

Number of adult = 6

Number of child = 3

To find the cost of ticket if she uses her credit card.

Formula

If a% increases on b the value will be = b× $\frac{100+a}{100}$

Total cost of the ticket = £12×6+£6×3 = £90

After 10% booking fee = £90× $\frac{110}{100}$ = £99

After paying by her credit card 2% = £99× $\frac{102}{100}$ = £100.98

Hence,

She has to pay £100.98.

£72 plus £18 equals £90 and 10% makes it £81.00 and with the 2% it’s £82.62

Given points A (0,0), B (4,0), C (0,2), D (0,0), E (2,0), and F (0,1), which of the following proves that

Similar triangles may or may not have equal side lengths

Triangles ABC and DEF are similar by SSS theorem

<h3>How to determine the similarity statement</h3>

The coordinates of the two triangles are:

A (0,0), B (4,0), C (0,2), D (0,0), E (2,0), and F (0,1)

Calculate the lengths of both triangles using the following distance formula

$d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}$

For triangle ABC, we have:

$AB = \sqrt{(0 -4)^2 + (0 -0)^2} = 4$

$BC = \sqrt{(4 -0)^2 + (0 -2)^2} = 2\sqrt 5$

$CA = \sqrt{(0 -0)^2 + (0 -2)^2} = 2$

For triangle DEF, we have:

$DE = \sqrt{(0 -2)^2 + (0 -0)^2} = 2$

$EF = \sqrt{(2 -0)^2 + (0 -1)^2} = \sqrt 5$

$FD = \sqrt{(0 -0)^2 + (1 -0)^2} = 1$

Divide corresponding sides of the triangles to calculate the scale factor k

$k = \frac{AB}{DE} = \frac{BC}{EF} = \frac{CA}{FD}$

This gives

$k = \frac{4}{2} = \frac{2\sqrt 5}{\sqrt 5} = \frac{2}{1}$

Evaluate the quotients

$k = 2 = 2 = 2$

Since the quotients are equal, then the triangles are similar

Hence, triangles ABC and DEF are similar by SSS theorem

Find the area of a square with a diagonal of 8cm.

klio [65]

You have to use the Pythagorean theorem but there is a little twist here since a square has has equal sides. So:
x^2+x^2=8
2x^2=8
2/2x^2=8/2
x^2=4
√x^2=√4
x=2
The side of the square is 2.
So now the area of a square is:
Side×Side
2×2=4
The area of the square is 4 centimetres

Determine if the solution set for the system of equations shown is the empty set, contains one point or is infinite. x + y = 6 x

Mnenie [13.5K]

The solution of the system of equations contains one point

<h3>How to determine the number of solutions?</h3>

The system is given as:

x + y = 6

x - y = 0

Add both equations

2x = 6

Divide by 2

x = 3

Substitute x = 3 in x - y = 0

3 - y = 0

Solve for y

y = 3

So, we have x =3 and y = 3

Hence, the solution of the system of equations contains one point
