Answer:

Number of child tickets sold = 31

Step-by-step explanation:

Let,

x be the number of child tickets sold

y be the number of adult tickets sold

According to given statement;

y = 4x      Eqn 1

5.80x + 9.20y = 1320.60     Eqn 2

Putting y=4x in Eqn 2

5.80x + 9.20(4x) = 1320.60

5.80x + 36.80x = 1320.60

42.60x = 1320.60

Dividing both sides by 42.60

[tex]\frac{42.60x}{42.60}=\frac{1320.60}{42.60}\\x = 31[/tex]

Hence,

Number of child tickets sold = 31

Answer:

Solution,

Let the coordinates of A and B be (x, y) and (3x, 4y) respectively.

Then, the gradient (Slope) of AB is given by:

m = [tex]\frac{4y-y}{3x-x}[/tex]

or, m = [tex]\frac{3y}{2x}[/tex]

This is the required gradient of the line in terms of x and y.

Answer:

  C = 56.52 in

  A = 256.34 in²

Step-by-step explanation:

The figure is trying to show you that d=18 in, so r=9 in. The formulas for C and A are given, so you only need to put the numbers in the formula and do the arithmetic. Apparently, you're supposed to use 3.14 for π.

  C = πd = (3.14)(18 in) = 56.52 in

  A = πr² = (3.14)(9 in)² = (3.14)(81) in² = 254.34 in²

Answer:

top one is 48 cm, bottom one is 17.5in.

Step-by-step explanation:

From what I understand, these shapes are increasing in size, so they will increase at a certain number. Our top one is rotated, but the 12cm is equivalent to the 3cm from the previous rectangle, thus making it greater by 4 times. To find x, we multiply 12cm by 4 to get 48cm. Same concept for the shapes on the bottom. Our 56in is equivalent to 8in, making it 7 times larger. Now, we multiply 2.5 by 7 to get 17.5in.

Answer: No because 1/2 is equal to 6/12 because 1 x6=6 and 2x6 =12 which makes 1/2 equivalent to 6/12 not 7/12

Answer:

B. -6

Step-by-step explanation:

Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]

Where,

b = 4, f(b) = -15

a = 2, f(a) = -3

Plug in the values

[tex] \frac{-15 - (-3)}{4 - 2} [/tex]

[tex] = \frac{-12}{2} = -6 [/tex]

The average rate of change of the given quadratic function in the given interval is -6.

On the graph, we can see that:

f(4) = -15

f(2) = -3

Then the average rate of change on that interval will be:

[tex]y = \frac{f(4) - f(2)}{4 - 2} = \frac{-15 + 3}{2} = -6[/tex]

Then we conclude that the average rate of change of the given quadratic function on the given interval is -6.

Step-by-step explanation:

I believe its 2 ^ -3

because

Answer:

Angle 1 =  108°

Angle 2 =  72°

Angle 3 =  120°

Angle 4 =  96°

Angle 5 =  144°

Step-by-step explanation:

We need to find the measures of the interior  angles in a pentagon if the measure  of each consecutive angle is in the  ratio 9:6:10:8:12.

Let x be the common ratio

So, we can write:

Angle 1 = 9x

Angle 2 = 6x

Angle 3 = 10x

Angle 4 = 8x

Angle 5 = 12x

We know that the sum of all angles of pentagon = 540

So, adding all angles and equal them to 540, we can find value of x

[tex]9x+6x+10x+8x+12x=540\\45x=540\\x=\frac{540}{45}\\x=12[/tex]

So, we get the value of x: x=12

Now, calculating the angles by putting x=12:

Angle 1 = 9x = 9(12) = 108°

Angle 2 = 6x = 6(12) = 72°

Angle 3 = 10x = 10(12) = 120°

Angle 4 = 8x = 8(12) = 96°

Angle 5 = 12x= 12(12) = 144°

$1.77

Step-by-step explanation:

$1 plus 75 cents plus 2 cents

The total amount of money that Rachel has is $1.77.

The study and use of numbers, their relationships, and mathematical observations are topics covered by the area of mathematics known as arithmetic. The word "arithmetic" (which derives from the Greek word "arithmos," "number") is frequently used to refer to the basic ideas in measuring, calculation, and number theory (specifically, the operations of addition, subtraction, multiplication, division, raising to powers, and root extraction).

As per the given data:

We are given the amount of dollar bills, quarters and pennies Rachel has.

Dollar bills = 1

Quarters = 3

Pennies = 2

1 Dollar bill = $1

1 Quarter = $0.25

1 Penny = $0.01

Total money that Rachel has

= 1 × (Dollar bill) + 3 × (Quarters) + 2 × (Pennies)

= 1 × ($1) + 3 × ($0.25) + 2 × ($0.01)

= 1 + 0.75 + 0.02

= $1.77

The total amount of money that Rachel has is $1.77.

Hence, The total amount of money that Rachel has is $1.77.

Step-by-step explanation:

Answer:

1. x² – 11x + 24

2. a² + 5a + 6

Step-by-step explanation:

1. (x – 3)(x – 8) =?

Use the entities in the first bracket to multiply the second bracket. This is illustrated below:

(x – 3)(x – 8)

x (x – 8) – 3(x – 8)

x² – 8x – 3x + 24

x² – 11x + 24

Thus, the product of (x – 3)(x – 8) is

x² – 11x + 24

2. (a + 3)(a + 2) =?

Use the entities in the first bracket to multiply the second bracket. This is illustrated below:

a(a + 2) + 3(a + 2)

a² + 2a + 3a + 6

a² + 5a + 6

Thus, the product of (a + 3)(a + 2) is:

a² + 5a + 6

Answer:

£91.80

Step-by-step explanation:

You first have to think, what is 15% of £36.72?

To do this, simply divide 100 by 3672, as we converted £36.72 to pence.

So 3672/100= 36.72. Then we multiply it by 15, which gives us 550.8

We then convert it back to pounds.

After you work that out you will get an answer of £55.08

We then add £55.08 to £36.72 and that will give us the answer, which is...

£91.80

OR

A quicker way is 15/100 of £36.72. Add the answer to £36.72= £91.80
