Answer:

£100.80

Step-by-step explanation:

Lets start with the original price of the tickets.

£12 x 6 = £72

£6 x 3 = £18

£18 + £72 = £90

So now we know the tickets would have cost £90.

We now have to work out how much 10% is.

To do that, we have to divide by 10

90 / 10 = 9

10% = £9

Add that the the ticket cost.

£90 + £9 = £99.

Then we have the 2% for the credit card.

To get 2%, we first have to find 1%, which is found by dividing by 100

90 / 100 = 0.9

1% = 0.90

0.9 x 2 = 1.8

2% = 1.80

Add that to the previous total and there's your answer.

£99 + £1.80 = £100.80

What is the value of x?

Yuliya22 [10]

Answer:

Step-by-step explanation:

∠QRT and ∠SRT are supplementary angles,

therefore m∠QRT + m∠SRT = 180°.

(45x)° + m∠SRT = 180° subtract (45x)° from both sides

m∠SRT = 180° - (45x)°

We know: the sum of the measures of the angles of the triangle is equal to 180 °. Therefore we have the equation:

(180 - 45x) + (57 + x) + 25x = 180 combine like terms

(-45x + x + 25x) + (180 + 57) = 180

-19x + 237 = 180 subtract 237 from both sides

-19x = -57 divide both sides by (-19)

x = 3

To create a unique house paint color, Melton mixes together a sample that is 12 gallons of red, 2.5 gallons of yellow and 0.5 ga

Mariana [72]

Answer:

180

Step-by-step explanation:

total ratio is 15

gallons of red =

$\frac{12}{15} \times 6 \times \frac{15}{0.5 } \\ \\ = 144$

gallons of yellow

$30$

gallons of blue

$\frac{0.5}{15} \times 30 \times \frac{15}{2.5} \\ \\ = 6$

total =144+30+6

=180

Answer:

Median for sample 1 = 142

Median for sample 2 = 134

Step-by-step explanation:

For Sample 1:

For finding median, the data is first arranged into ascending or descending order. We are arranging the data in ascending order.

120, 130, 132, 136, 139, 142, 142, 144, 156, 165, 167

The formula for calculating the term which will be median is:

Median= ((n+1)/2)

Here in sample 1, n=11

So, putting n=11 in the formula

= ((11+1)/2)

= (12/2)

=6th term

The sixth term is 142, so

Median of sample 1=142

For Sample 2:

For finding median, the data is first arranged into ascending or descending order. We are arranging the data in ascending order.

112, 112, 113, 114, 125, 134, 141, 145, 146, 163, 165

The formula for calculating the term which will be median is:

Median= ((n+1)/2)

Here in sample 2, n=11

So, putting n=11 in the formula

=((11+1)/2)

=(12/2)

=6th term

The sixth term is 134, so

Median of sample 2=134

Alja [10]

Answer:

$x=134.05m$

Step-by-step explanation:

From the question we are told that:

Slant Height of Kite $h_s=175$

Angle $\theta=40 \textdegree$

Since Emma,The Kite and Andrew forms a right angle triangle

Generally the equation for distance between Andrew from Emma is mathematically given by

$x=h_scos\theta$

$x=175cos40$

$x=134.05m$
