The value of the missing variable x in the diagram is; 4

In mathematics, two triangles are said to be similar provided that they have the same ratio of corresponding sides and equal pair of corresponding angles.

Now, from the given image, we can see that DE bisects AC into 2 equal parts and by virtue of the concept of similar triangles, we can say that;

DE/BC = 1/2

We are given;

DE = x + 1

BC = 4x - 6

Thus;

(x + 1)/(4x - 6) = 1/2

Cross multiply to get;

2x + 2 = 4x - 6

4x - 2x = 6 + 2

2x = 8

x = 4

That value of x is the missing value required in conclusion.

Answer:

31

Step-by-step explanation:

The median is the number that we find in the middle of the data.

So if we have a sequence of {1,2,3}

Then 2 is the median

If we have a sequence of {1,2,3,4,5}

Then 3 is the median

We look in the middle of 28,30,30,30,30,31,31,31,31,31,31,31,31

and we find 31 in the middle.

Note:

If the middle is something with 2 terms in the middle like

1,2,3,4

Then the median is the average of the two middle terms which is

(2+3)/2 = 2.5

A ratio shows us the number of times a number contains another number. The cost of cheese that is needed to make 6000g of potato cake is £12.86.

A ratio shows us the number of times a number contains another number.

Given that the ratio of the ingredients is,

weight of potato: weight of cheese: weight of onion = 9: 2:1

Let the ingredients be mixed in the quantity 9x, 2x, and 1x, for 6000g of potato cake. Therefore, the value of x can be written as,

[tex]9x+2x+1x = 6000\\\\12x = 6000\\\\x = 500[/tex]

Hence, the value of x is 500.

Thus, the amount of cheese that will be needed is 2x,

[tex]2x = 2 \times (500) = 1000g[/tex]

Given that the cost of 175g of cheese is  £2.25, therefore, the cost of 1g of cheese will be,

[tex]\text{Cost of 1g cheese} = \£\dfrac{ 2.25}{175}[/tex]

Now, the cost of 1000g of cheese will be,

[tex]\text{Cost of 1000g cheese} = 1000\times \£\dfrac{ 2.25}{175} = \£12.86[/tex]

Hence, the cost of cheese that is needed to make 6000g of potato cake is £12.86.

Answer:

(34.15, 47.85)

Step-by-step explanation:

[tex]n = (\frac{z*stddev}{ME} )^{2}[/tex]

stddev = 11.9

z = invNorm(

area = (1 + confidence interval)/2

mean = 0

stddev = 1

)

= invNorm(

0.995

0

1

)

≈ 2.576

n = 20

square root both sides

[tex]\sqrt{20} = 2.576 * 11.9 / ME[/tex]

multiply both sides by ME, divide both sides by √20 to isolate ME
ME = 2.576 * 11.9/√20

≈ 6.85

interval = mean ± ME
= (41-6.85, 41+6.85)

= (34.15, 47.85)

The question is an illustration of the laws of cosine, the length of the third side is 6.7 units

The measure of the third side is calculated using the following law of cosine

a^2 = b^2 + c^2 - 2bc * cos(A)

So, we have:

a^2 = 8^2 + 11^2 - 2 * 8 * 11 * cos(37)

Evaluate the expression

a^2 = 44.44

Take the square root of both sides

a = 6.7

Hence, the length of the third side is 6.7 units

Answer:

x = 4

Step-by-step explanation:

Given equation:

To determine the value of "x", we need to isolate the "x" variable and it's coefficient. This can be done by adding 4 to both sides of the equation.

The next step in determining the "x" variable is to isolate the coefficient from the "x" variable. This can be done by dividing 3 both sides of the equation.

Therefore, the solution (x) is 4.
