Find the value of the expression: -4.65 + 8.3 - (-2.35)

For given triangle, the value of x is 22.

In this question, we have been given three angles of triangle.

We need to find the value of x.

We can observe that (6x - 7)° is an exterior angle.

So, the third angle of the triangle is 180° - (6x - 7)°

We know that the sum of the all angles of the triangle is 180°

2x° + (103 - x)° + [180° - (6x - 7)°] = 180°

2x + 103 - x + 180 - 6x + 7 = 180

2x - x - 6x + 103 + 180 + 7 = 180

-5x + 290 = 180

-5x = 180 - 290

-5x = -110

x = 22

Therefore, for given triangle, the value of x is 22.

[tex]s - p = 40[/tex]

IT SIMPLY MEANS THAT THE DIFFERENCE BETWEEN s as a large number and p as a small number is 40.

Answer:

£75 > £70 Therefore Sally is wrong.

Step-by-step explanation:

1. First we need to find the volume of the sand pit  

     60x40x100= 24,000[tex]cm^{3\\[/tex]

 Volume= 24,000[tex]cm^{3\\[/tex]

2. We need to convert 8 liters to [tex]cm^{3\\[/tex] so, all the units are the same

     1 liter= 1,000[tex]cm^{3\\[/tex]

     8 liters= 8,000[tex]cm^{3\\[/tex]

3. We then do 24,000[tex]cm^{3\\[/tex] divide by 8,000[tex]cm^{3\\[/tex] to see how many bags, we need

    24,000[tex]cm^{3\\[/tex]/ 8,000[tex]cm^{3\\[/tex] = 30

so, Sally needs 30 bags

4. We know one bag cost £2.50 to know how much 30 bags cost we do

   £2.50 x 30 = £75

so, we know 30 bags cost £75

5. Sally statement was said that it would cost less than £70 which is false as it costs £75

6. Therefore the final answer is £75>£70 so Sally is wrong.

The slope of AB = 2

The slope of CD = 2

Both lines are parallel lines.

The lines that are perpendicular to each other have slope values that are negative reciprocal of each other.

For example, if the a line's slope is a, the line that is perpendicular to it will have a slope of -1/a. This is because the negative reciprocal of a is -1/a, and (a)(-1/a) = -1.

On the other hand, the lines that are parallel to each other will have the same slope value.

Given the following:

A(−6 , −9)

B(8, 19)

C(0, −4)

D(2, 0)

Find the slope (m) of AB:

Slope of AB = (19 -(-9))/(8 -(-6))

Slope of AB = 28/14

Slope of AB = 2

Find the slope (m) of CD:

Slope of CD = (0 -(-4))/(2 - 0)

Slope of CD = 4/2

Slope of CD = 2

The graph of both lines are shown below.

Thus, the slope of AB and CD are the same, therefore, we can conclude that lines AB and CD are parallel to each other.

The value of x is 26° and y is 9°.

A pair of neighboring angles created by the intersection of two lines is known as a linear pair of angles. When two angles share a vertex and an arm but do not overlap, they are said to be adjacent angles. Due to their formation on a straight line, the linear pair of angles are always complementary. So, the total of two angles in a pair of lines is always 180 degrees.

The value of x and y are : x= 26° and y= 9°.

As a linear pair, (5x - 17)° + (3x - 11)° = 180°.

or, 8x - 28°= 180°

8x = 180° + 28°

Therefore, the value of x is 26°.

Now,

3x - 11°= 3×26°-11° = 67°

Again,

67°+90°+(2y+5)° = 180° { being linear pair}.

157°+2y+5° = 180°

or, 2y + 162° = 180°

or, 2y = 180° - 162°

y =

Therefore, the value of y is 9°.

The value of x is 26° and y is 9°.

The value of m + n from getting the values of m and n from the constant polynomial P(x) = (2m - 4)x² + (5 - n)x + 13 is; 7

A constant Polynomial is defined as a polynomial is a function of the form f(x) = a

where a is a real number, whose highest degree is zero.

Thus, examples of constant Polynomials are f(x) = 5, g(x) = -11 , h(y) = 7/4

Now, we are given the polynomial expression;

P(x) = (2m - 4)x² + (5 - n)x + 13

From the definition of constant Polynomials, we can say that;

2m - 4 = 0 and 5 - n = 0

There is a 0.0003 chance that the sample mean was 18.2 ounces or more if the actual mean is 18 ounces.

So, let Y be a random variable with box weights.

These are the sample size and mean:

N's standard deviation is then roughly followed by Y ( μ = 18, SD = 0.32).

Z score is displayed as:

Where z has a mean of 0 and a standard deviation of 1 and is a normal standard variable.

Given that the standard deviation is given and that sample size n is 30. y roughly follows the Normal distribution.

If the sample mean was 18.2 ounces or more and the actual mean was 18 ounces, the probability that this was the case is given as:

[tex]\begin{aligned}&P[Y \geq 18.2]=P\left[\frac{\sqrt{n(y-u)}}{S D} \geq \frac{\sqrt{30}(18.2-18)}{0.32}\right. \\&=P\left[z \geq \frac{\sqrt{30}+0.2}{0.32}\right] \\&=P\left[z \geq \frac{1.0954}{0.32}\right] \\&=P[z \geq 3.4233] \\&=0.0003\end{aligned}[/tex]

1 . In the given triangle ΔNBA BO is a median.
By applying the property of median it divides the opposite side into two equal parts.
Therefore,
NO = OA ...(a)
We have,
NO = x+3 and OA = 2x-9

from (a)
NO = OA
x+3 = 2x-9
∴ 3+9 = 2x-x
∴ x = 12
∴ The Value of x is 12.

Que 2 - In ΔMTV
Given - TP is an angle bisector
             m∠MTP = 12 , m∠MTV = 3x - 3.
Ans - TP is an angle bisector which means it divides the angle into two equal parts. (By angle bisector theorem)
∴ m∠MTP = m∠VTP ..... (a)
m∠MTV = m∠MTP + m∠VTP
∴m∠MTV = 2(m∠MTP)
∴3x-3 = 2(12)
∴3x-3 = 24
∴3x = 24 + 3
∴3x = 27
∴ x = 27/3
∴ x = 9
∴ The Value of x is 9.
