Numbers of packs p is 12

Step-by-step explanation:

Data :

  Money  = $18

 Price of a  card = $1.5

 Equation     :    18 ≥ 1.5p

Solve the equation  for p

       18/1.5  ≥  p

     12 ≥ p

Answer:

C

Step-by-step explanation:

Angle 1 and angle 4 sit on the same straight line which means

<1 + <4 = 180          

We are given that <4 = 105 degrees. So the equation above becomes.

<1 + 105 = 180                  Subtract 105 from both sides

<1 = 180 - 105

<1 = 75

Answer:

0839

Step-by-step explanation:

First of all, let's cancel 0620 and 0746, because they dont have any other number that has the same last 2 digits as them. Jean would've immediately known the train number if it was one of these two.

Now, when Marie says "I'm sure that neither does Jean", it means she is guaranteed Jean doesn't know the train number. It mean she couldnt've gotten 06 or 07, as 0620 and 0746 have it.

We're left with 0825,0839,0917,0925 and 0950
When Jean replies he knows the train number, it means he couldnt've gotten 25, as it's repeated.

And when Marie responds she knows as well, she couldnt've gotten 09, as it's also repeated.

We can cancel 0825,0917,0925 and 0950

So, the train number is 0839

Answer:

x = 30

y = 114

Step-by-step explanation:

considering DC || AB the sum of angle <D and angle <A must be equal to 180 because they are supplementary:

5x + x = 180 add like terms

6x = 180 divide both sides by 6

x = 30

Same goes for angle <C and angle <B:

y + 2.2x = 180 we know the value of x is 30

y + 2.2*30 = 180

y + 66 = 180 subtract 66 from both sides

y = 114

Answer:

b > -3

Step-by-step explanation:

-5(2b+7) + b< -b - 11

Distribute -5

-10b - 35 + b < - b - 11

Combine like terms.

-9b - 35 < - b - 11

Add b to both sides.

-8b - 35 < -11

Add 35 to both sides.

-8b < 24

Divide by -8. REVERSE THE SYMBOL!! because dividing by a negative number.

b > -3

Answer:

204 ft²

Step-by-step explanation:

Let's split the room to make it look like there are two squares.

We can make it to where one square is 14 ft long and 10 ft wide.

The other square can be 16 ft long and 4 ft wide

Find the areas of those two squares by multiplying width and length

14 x 10 = 140

16 x 4 = 64

Add those two together

140 + 64 = 204

The amount of money Candy started with after spending on drinks and cakes is £7.95

She bought a drink for £1.45 and a piece of cake for £1.20.

She has two thirds of here money left.

Let the money she has initially  = x

Therefore,

2 / 3 x = x - 1.45  - 1.20

2 / 3 x = x - 2.65

subtract x from both sides

2 / 3 x - x = - 2.65

2x - 3x / 3 = - 2.65

- x / 3 = - 2.65

cross multiply

-x = - 2.65 × 3

- x = -7.95

x = £ 7.95

Therefore, Candy started with £7.95

[tex]y = (5 + x)^2[/tex]

Step-by-step explanation:

"The square of the sum of x and 5 is equal to y."

Let's use our clue words that indicate what our equation will be.

Let's start easy, equal to y.

y =

Now let's look at the rest of the sentence minus the phrase we just used.

The square of the sum of x and 5.

The sum of x and 5 goes first,

x + 5

and since we are looking for the square of x + 5:

(5 + x)^2

therefore,

[tex]y = (5 + x)^2[/tex]

Answer:

Step-by-step explanation:

So, to graph a parabola we must have at least 3 points, the x intercepts and the turning point. Currently the equation is in x intercept form which means that we know straight away (assuming the equation =0) that the x intercepts are:

(1,0) and (-3,0)

Now we have to find the turning point and we can do this by putting the equation into turning point form:

-5/4([tex]x^{2} +2x-3[/tex])

-5/4(([tex](x+1)^{2} -3-1[/tex])

-5/4[tex](x+1)^{2}+5[/tex]

Now we can figure out the turning point which is:

(-1,5)

Graph those three points and you should get a parabola shape

Product of two polynomials can be done by distribution of multiplication over addition. The product of [tex](x+5)(x-5) = x^2 - 25[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is obtained as:

[tex](x+5)(x-5) = x(x - 5) + 5(x - 5) \\\\(x+5)(x-5) = x^{1+1} - 5x + 5x - 25 = x^2 - 25[/tex]

Thus,

The product of [tex](x+5)(x-5) = x^2 - 25[/tex]

The value of ∠BAC in the isosceles triangle is 9.7°

Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:

a² = b² + c² - 2bc*cos(A)

where a, b, c are the sides of the triangle and A, B, C are the angles opposite the sides.

AB = AC = 1185 (isosceles), BC = 200, let ∠BAC = x°, hence:

200² = 1185² + 1185² - 2(1185)(1185)cos(x)

2(1185)(1185)cos(x) = 2808450

cos(x) = 0.9857

x = 9.7°

Given Data set of people who attend the concert has a mean of 36.4.

the sum of the values by adding them all up. Divide the sum by the number of values in the data set is known as the mean.

Given The data set shows the number of people who attended a concert over a period of 10 days.

12, 35, 27, 55, 22, 23, 60, 49, 15, 66

the Sum of the given data set = 364

from the general formula of the mean

mean = (sum of data)/ number of data

Given the number of data = 10

Thus

Mean = 364 / 10

Mean = 36.4
