What is the value of x?

Answer: £9.3 more

Step-by-step explanation:

Price for winter tickets: £18 + £18 + £14 = £50

Summer tickets pricing:

£18 + 20% = £21.6  

£14 + 15% = £16.1

Price for summer tickets: £21.6 + £21.6 + £16.1 = £59.3

Subtract winter tickets from summer tickets for difference:

£59.3 - £50 = £9.3

The different units of measurement (millimeters, centimeters, meters and kilometers) are used to measure from very short distances such as the amount of a medicine in a syringe to long distances between cities.

Measurement units are a series of references that are used to measure different elements and factors. Specifically, the units of measure for distance measure the distance between two points.

However, not all units of measure work for all situations, for example:

Step-by-step explanation:

[tex]~~~~~~(8x-17)+(3x+2)+63 = 180\\\\\implies 11x +48=180\\\\\implies 11x = 180-48\\\\\implies 11x = 132\\\\\implies x= \dfrac{132}{11}\\\\\implies x= 12[/tex]

Answer:

x = 12.

Step-by-step explanation:

The sum of the 3 angles is 180, so:

8x - 17 + 3x + 2 + 63 = 180

11x -15 + 63 = 180

11x = 180  + 15 - 63

11x = 132

x = 132/11 = 12

Answer:

the cost of the textbook was $173.14 before the tax was added

Step-by-step explanation:

6.75% of $185.67 is 0.0675 x $185.67 = $12.53

$12.53 is 6.75% of $185.67

sine $185.67 is the total AFTER we subtract the amount

$185.67 - $12.53 = $173.14

Answer:

(a)  (3, 0) and (-8, 0)

(b)  (-2.5, 0)

(c) x = -2.5

(d) f(-2.5) = -30.25

Step-by-step explanation:

Given quadratic function:

[tex]f(x)=(x-3)(x+8)[/tex]

The x-intercepts are when [tex]f(x)=0[/tex]

[tex]\implies f(x)=0[/tex]

[tex]\implies (x-3)(x+8)=0[/tex]

[tex]\implies (x-3)=0 \implies x=3[/tex]

[tex]\implies (x+8)=0 \implies x=-8[/tex]

Therefore, the x-intercepts are (3, 0) and (-8, 0)

Midpoint between two points:

[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad[/tex]

[tex]\textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]

[tex]\implies \textsf{Midpoint of the x-intercepts}=\left(\dfrac{-8+3}{2},\dfrac{0+0}{2}\right)=\left(-2.5},0\right)[/tex]

The extreme point of a quadratic function in the form [tex]f(x)=ax^2+bx+c[/tex] is:

[tex]x=-\dfrac{b}{2a}[/tex]

Therefore, expand the function so that it is in standard form:

[tex]\implies f(x)=x^2+5x-24[/tex]

[tex]\implies a=1, b=5[/tex]

Therefore, the extreme value is:

[tex]\implies x=-\dfrac{5}{2}=-2.5[/tex]

Alternative method

A quadratic function has an extreme value at its vertex.

The x-value of the vertex is the midpoint of the x-intercepts.

Therefore, the extreme value is x = -2.5

[tex]\begin{aligned}\implies f(-2.5) & =(-2.5-3)(-2.5+8)\\& = (-5.5)(5.5)\\& = -30.25\end{aligned}[/tex]

Step-by-step explanation:

Answer:

2.6 m

Step-by-step explanation:

The surface area for rectangular prisms is: S = 2lw + 2lh + 2wh, where l = length, w = width, h = height.

Substitute the known values into this equation: h = 5, l = 10, w = x, S = 178

178 = 2(10x) + 2(5 x 10) + 2 (5x)

Simplify!

178 = 20x + 100 + 10x

Subtract 100 from both sides and combine x's

78 = 30x

divide both sides by 30

x = 2.6 m

answer check: 2(10 x 2.6) + 2(5 x 10) + 2 (5 x 2.6) = 178 (true!)

Julia has the greater median

Julia also has the greater mean.

Averagely, Julia practiced for a greater amount of time each day.

Mean = sum of data points / number of data points.

Median = center/middle of the data distribution.

Mean for Julia = (20 + 20 + 30 + 60 + 60 + 60 + 70 + 70 + 100 + 100 + 100 + 115 + 115 + 115)/14 = 69.6

Mean for Hannah = (20 + 20 + 30 + 30 + 45 + 45 + 45 + 70 + 70 + 70 + 75 + 90 + 90 + 120)/14 = 58.6

Median for Julia = 70

Median for Hannah = (45 + 70)/2 = 57.5

Julia has the greater median and also has the greater mean.

Averagely, we can conclude that Julia practiced for a greater amount of time each day.

Answer:

a = 2.5

Step-by-step explanation:

It is mentioned that 2 is a zero of the polynomial f(x) = ax² - 3(a - 1)x - 1

So that means :

⇒ f(x) = 0

⇒ x = 2

Substituting and solve for a :

⇒ 0 = a(2)² - 3(a - 1)(2) - 1

⇒ 0 = 4a - 6(a - 1) - 1

⇒ 0 = 4a - 6a + 6 - 1

⇒ 2a = 5

⇒ a = 2.5

Answer:

0.892

Step-by-step explanation:

The probability that it is raining and the flight is delayed is 0.008.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, the probability that it will rain is 0.14 and the probability that the flight will be delayed is 0.06.

Let P(A)=0.14 and P(B)=0.06

Here, P(A and B)=P(A)×P(B)

=  0.14 ×0.06

= 0.0084

= 0.008
