Step-by-step explanation:

5 : 1

We know that there is 120 cl of orange squash so

( Water : orange squash )

5 : 1

? : 120

We are multiplying by 120 to get from 1 to 120 so we must multiply by 120 to get from 5 to ?.

So,

5 × 120 = 600

Answer:

600 cl

Step-by-step explanation:

1 unit of orange = 5 units of water

120 units of oranges = 120 x 5 = 600 units of water

600 units of water = 600 cl of water

there are 80 buttons

7/10

3÷24=8 8×7=56 56+24=80

The total number of buttons in the container is 60. This was calculated by setting up an equation using the given proportion of black buttons and the difference between the number of black and white buttons.

Let the total number of buttons in the container be x. Given that 7/10 of the buttons are black, this means 7/10 of x, or (7/10)x, represent the number of black buttons. The remaining 3/10 of x are white buttons. The difference between the number of black and white buttons is 24, so we can set up the following equation:

(7/10)x - (3/10)x = 24.

Simplifying the equation by subtracting the fractions results in (4/10)x = 24.

We can then simplify this further by dividing both sides by the coefficient of x, which is (4/10), to find x.

x = 24 / (4/10) = 24 * (10/4) = 24 * (2.5) = 60.

So, there are 60 buttons in the container in total.

Folder = 1.25$

Notebook = 4.5 $

Folder =x

Notebook = y

The cost of one folder if the prices did not change between the days, for this case, is $1.25

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Given that:

To find:

Cost of one folder.

Assume that:

Then, from the given condition, we get:

Amount spent in buying 3 folders and 1 notebook = 3x + 1y dollars = $8.25

And, amount spent in buying 2 folders and 3 notebook = 2x + 3y dollars = $16

Thus, we get two equations as:

[tex]3x + 1y = 8.25\\2x + 3y = 16[/tex]

From the first equation, getting 'y' in terms  of 'x', we get:

[tex]y = 8.25 - 3x[/tex]

Substituting this in second equation, we get:
[tex]2x + 3(8.25 - 3x) = 16\\2x +24.75 -3x = 16\\(2-9)x = 16 - 24.75\\-7x = -8.75\\7x = 8.75\\x = 8.75/7 =1.25 \: \rm dollars[/tex]

As we have Cost of one folder = $x

Thus, the cost of one folder if the prices did not change between the days, for this case, is $1.25

Answer:

[tex]x=66[/tex]

Step-by-step explanation:

Since  MN and MP are tangent to circle O, they create 90° angles at the points of intersection.

We also know that this is a quadralateral, so the interior angles add up to 360.

We can make an equation with this information.

[tex]114+90+90+x=360[/tex]

[tex]294+x=360[/tex]

[tex]x=66[/tex]

By property of tangent, the value of x is Option(C) 66° .

The properties of tangent are as follows -

Given that point O is the center if the circle also given MN and MP are tangent to O.

Thus by the property of tangent, ∠OPM and ∠ONM is equal to 90° as both the tangents intersect at the points P and N .

Also from property, we know that -

⇒ ∠ONM + ∠OPM + 114° + x° = 360°

⇒  90° + 90° + 114° + x° = 360°

⇒ 294° + x° = 360°

∴  x = 360° - 294° = 66°

Therefore, by property of tangent, the value of x is Option(C) 66° .

The mean of the data is 4.5 and the median of the data is 5.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

To find the mean of the data, we add up all the values and divide by the total number of values:

2 + 7 + 5 + 4 + 3 + 3 + 5 + 5 + 6 + 5 = 45

There are 10 values, so:

mean = 45 / 10 = 4.5

Therefore, the mean of the data is 4.5.

To find the median of the data, we need to first put the values in order from smallest to largest:

2, 3, 3, 4, 5, 5, 5, 5, 6, 7

There are 10 values, which is an even number, so we take the average of the two middle values:

median = (5 + 5) / 2 = 5

Therefore,  the mean of the data is 4.5 and the median of the data is 5.

The surface area of the pyramid is 156 square inches. It is found by computing the area of the base, then adding it with the product of half of the base perimeter and the slant height.

The problem involves finding the surface area of a pyramid with a square base. The surface area of a pyramid is given by the formula Base area + 1/2 * Perimeter of the base * Slant height.

First, let's compute the area of the base, the base is a square with sides of 6 inches. This gives us 6 * 6 = 36 square inches.

Secondly, the perimeter of a square is simply the length of one side multiplied by 4, which gives us 6*4 = 24 inches. Then multiply this by the slant height, which is 10 inches, then by 1/2, we have 0.5 * 24 * 10 = 120 square inches.

Finally, adding the base area and the latter computation gives: 36 + 120 = 156 square inches. Therefore, the surface area of the wooden pyramid puzzle is 156 square inches.

The surface area of the wooden pyramid puzzle with a base side length of 6 inches and a slant height of 10 inches is 156 square inches.

To find the surface area of the wooden pyramid puzzle, we need to calculate the area of each face and then sum them up. The base of the pyramid is a square with side lengths of 6 inches, so the area of the base is 6 inches multiplied by 6 inches, which gives us 36 square inches. The four triangular faces have the same area since the pyramid is symmetrical, so we just need to calculate the area of one triangular face.

The height of the pyramid is given as 10 inches, and since it is a right triangle, we can use the formula for the area of a triangle: (base x height) / 2.

The base of the triangle is the length of one side of the square base, which is 6 inches. Therefore, the area of one triangular face is (6 inches x 10 inches) / 2 = 30 square inches.

Since there are four triangular faces, the total area for all the triangular faces is 4 x 30 square inches = 120 square inches. Finally, we can sum up the areas of the base and the triangular faces to find the surface area: 36 square inches + 120 square inches = 156 square inches.

Answer:

the answer is B.  145 sq. ft.

Step-by-step explanation:

find the area of the first 2 triangles

A = 1/2 bh

A = 1/2 ba

a = 1/2 (11 ft.) (5 ft)

a =  27.5 sq ft.

A = 1/2 cb

a = 1/2 (5 ft) (7 ft)

a = 17.5 sq. ft

find the area of the rectangle

A = lw

a = (11 ft.)(5 ft.)

a = 55 sq. ft

Answer:

f(x) and g(x) are inverses

Step-by-step explanation:

* Lets check the inverse function

- If f(x) = y has a domain = x and a range = y, then f^-1 is the

  inverse of f with a domain  = y and a range = x

- f(x) = f^-1(x) = x

* Now lets solve the problem

∵ f(x) = 8/x

∵ g(x) = 8/x

∴ fg(x) = f(8/x)

∴ fg(x) = 8/(8/x) = 8 ÷ 8/x ⇒ change division sign to the multiplication

  sign and reciprocal the fraction after the division sign

∴ fg(x) = 8 × x/8 = x

* Now lets find gf(x)

∴ gf(x) = g(8/x)

∴ gf(x) = 8/(8/x) = 8 ÷ 8/x

∴ gf(x) = 8 × x/8 = x

∵ f(x) = f^-1(x) = x

* fg(x) = gf(x) = x

∴ f(x) and g(x) are inverses

Answer:

The range of f(x) is {-2 , 16 , 34 , 52} ⇒ answer d

Step-by-step explanation:

* Lets talk about the domain and the range of a function

- The domain is the values of x (input)

- The range is the value of y of the corresponding x (output)

∵ f(x) = 3x + 4

∵ The domain is {-2 , 4 , 10 , 16}

- To find the corresponding range substitute the values of x in f(x)

∵ x = -2

- Substitute x by -2 in f(x)

∴ f(-2) = 3(-2) + 4 = -6 + 4 = -2

∵ x = 4

- Substitute x by 4 in f(x)

∴ f(4) = 3(4) + 4 = 12 + 4 = 16

∵ x = 10

- Substitute x by 10 in f(x)

∴ f(10) = 3(10) + 4 = 30 + 4 = 34

∵ x = 16

- Substitute x by 16 in f(x)

∴ f(16) = 3(16) + 4 = 52

∴ The range of f(x) is {-2 , 16 , 34 , 52}

[tex]P(A and B) = \frac{39}{200} [/tex]

EXPLANATION

If A and B are independent events, then,

P(A and B)=P(A)×P(B)

It was given that:

[tex]P(A) = \frac{3}{10} [/tex]

and

[tex]P(B) = \frac{13}{20} [/tex]

[tex]P(A \: and \: B) = \frac{3}{10} \times \frac{13}{20} [/tex]

[tex]P(A and B) = \frac{39}{200} [/tex]

the probability of events A and B occurring together, P(A and B), is 39/200 or, when simplified, 0.195.

The subject of the question is finding the probability of both independent events A and B occurring together, which is represented by P(A and B). To calculate this, you simply multiply the probability of event A by the probability of event B since they are independent. Given that P(A) = 3/10 and P(B) = 13/20, the calculation would be as follows:

Thus, the probability of events A and B occurring together, P(A and B), is 39/200 or, when simplified, 0.195.
