The measures of those two angles are 105° and 135°

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

Two angles of a quadrilateral measure 110° and 10°.

And, The other two angles are in a ratio of 7 : 9.

Now, We know that;

The sum of all four interior angles of a quadrilateral are 360°.

Here, The other two angles are in a ratio of 7 : 9.

Hence, Measure of both angles are 7x and 9x.

So, We get;

⇒ 110° + 10° + 7x + 9x = 360°

⇒ 120 + 16x = 360

⇒ 16x = 360 - 120

⇒ 16x = 240

⇒ x = 15

Thus, Measure of both angles are;

⇒ 7x = 7 × 15 = 105°

⇒ 9x = 9 × 15 = 135°

Advantages of using a permutation as in problem 1 include increased efficiency and simplicity, while disadvantages include reduced flexibility and a potential loss of information.

Permutations are mathematical operations that rearrange elements in a list or sequence, and there are different ways to define and generate permutations. A permutation specified in problem 1 may have certain desirable properties, such as being easy to compute, having low computational complexity, or having a simple mathematical form.

These advantages, however, can also be disadvantages if they limit the ability to capture more complex or subtle relationships between elements, or if they prevent the use of other methods that may be more appropriate for a particular application. Therefore, the choice of a specific permutation method depends on the requirements of the problem and the available computational resources.

Answer:

they both last 1,25 hours

Step-by-step explanation:

Friday: 5*A + 3*B =10 hours

Saturday: 2*A + 6*B = 10 hours  --> A = (10-(6*B)) / 2

                                                          A = 5-(3B)

5*(5-3B) + 3B = 10

The total number of hours Josh worked during the week is 44.7 hours.

We first need to calculate his regular pay by dividing his weekly gross earnings by his hourly rate:

$487.29 / $10.95 = 44.7 hours

Since the company pays time-and-a-half for any hours worked exceeding 40 in one week, we need to determine if Josh worked more than 40 hours during the week. If he did, we'll calculate his overtime pay by multiplying his regular pay by 1.5.

If Josh worked 44.7 hours, then he worked 44.7 - 40 = 4.7 hours of overtime.

His overtime pay would be 4.7 hours * $10.95 * 1.5 = $81.48

His regular pay would be 40 hours * $10.95 = $438.00

So his total weekly pay would be $438.00 + $81.48 = $519.48

The total number of hours Josh worked during the week is 44.7 hours.

Answer:

[tex]\boxed{y = \dfrac{2}{5}x - 4}[/tex]

Step-by-step explanation:

Let's find the equation for the line

Take two distinguishable points on the graph.

(0, 4) and (2, -1) are two points with integer values for coordinates through which the line passes

The equation of a line in slope-intercept form is
y = mx + b

where
m = slope
b = y-intercept

Slope m = rise/run

rise = difference in y values of any two chosen points

run = difference in corresponding x values for the same chosen points

Taking the two points (0, 4) and (2, -1)

rise = -1 - 4 = -5

run = 2 - 0 =2

So slope = - 5/2

The y-intercept of this line is 4, - this is the y-value where the line crosses the y-axis and corresponds to the value of y when x = 0

The equation of the line is
y = mx + b
[tex]\rightarrow y = -\dfrac{5}{2}x + 4 \;\;\cdots \cdots (1)\\\\[/tex]

A line perpendicular to this line will have a slope that is the negative of the reciprocal of the slope.

The product of the two slopes will be -1

Reciprocal of -5/2 = -2/5
Negative of this is -(-2/5) = 2/5

So slope of perpendicular line = 2/5

Equation of line is
[tex]y = \dfrac{2}{5}x + b[/tex]

To find b plug in x, y values for (5, -2) and solve for b

[tex]-2 = \dfrac{2}{5}\cdot 5 + b\\\\[/tex]

[tex]-2 = 2 + b\\\\-4 = b\\\\b = -4\\[/tex]

The angle opposite to the smallest angle is the smallest side. Thus,

TS < US < TU.

If you have the perimeter P and width w , its length can be found with h = P/2−w . If you have the diagonal d and width w , it's length is h = √(d²−w²). When we're trying to find the hypotenuse we substitute our two known sides for a and b. It doesn't matter which leg is a and which is b. Then we solve for c by adding the squared values of a and b and taking the square root of both sides.

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.

Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.

In the given triangle the angle of interior angle is 180:

43z + z + 66 + z + 69 = 180

45z + 135 = 180

45z = 180 - 135

45z = 45

z = 1

The three angles are:

U = 43(1) = 43

T = 1 + 66 = 67

S = 1 + 69 = 70

The angle opposite to the smallest angle is the smallest side. Thus,

In the given Geometric shape/figure ∠1=∠4 i.e. C.

What are geometric shapes?

In Mathematics, Geometric shapes are the figures which demonstrate the shape of the objects we see in our everyday life. In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes.

Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as a square, circle, etc. Irregular shapes are asymmetrical. They are also called freeform shapes or organic shapes. For example, the shape of a tree is irregular or organic.

In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc.  In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can observe all these shapes in our daily existence also. For example books (cuboid shape), glasses (cylindrical shape), traffic cones (conical shape) and so on.

Now,

    As we know, If two lines intersect and make an angle, say X=45°, then its opposite angle is also equal to 45°.

The equation of the line that passes through the point (2, -3) and is parallel to the line y = 8 is y = -3.

What is the equation ?

The equation is a mathematical statement that shows the relationship between different values. It can be written using symbols, numbers and operations to describe the relationship between one or more variables. An equation usually consists of an equal sign (=) that separates two expressions which have the same value. For example, the equation 2+2=4 states that two plus two is equal to four.

The equation of a line is given by y = mx + b, where m is the slope and b is the y-intercept. Since the line is parallel to the line y = 8, they have the same slope, which is 0. Thus, the equation of the line that passes through the point (2, -3) is y = 0x + (-3). Simplifying this equation, we get y = -3.

The statement ∀x∃y∃z(y 6= z → p(x, y) ∧ p(x, z)) is false.

Let's start by understanding what "p" is. "p" is a function that takes in two arguments, x and y. It tells us whether the relationship between x and y is true or false.

Now, let's look at the statement

=>∀x∃y∃z(y 6= z → p(x, y) ∧ p(x, z)).

This statement says that for every x, there exists a y and a z such that y is not equal to z and both p(x, y) and p(x, z) are true.

This statement is actually false.

Why? Imagine if p(x, y) only returned true when y was equal to x. Then, there would be no y and z such that y is not equal to z and both p(x, y) and p(x, z) are true.

Therefore, it is possible for the function "p" to return false for the statement

=> ∀x∃y∃z(y 6= z → p(x, y) ∧ p(x, z)).

It depends on the definition of the function. To determine if the statement is true or false, we need to know what the function "p" is.

The formula for the slope a of the regression line is:

a = r(sy/sx)

The reason for the connection between the value of r and the slope of the least squares line has to do with the formula that gives us the slope of this line. For paired data (x,y) we denote the standard deviation of the x data by sx and the standard deviation of the y data by sy.

The formula for the slope a of the regression line is:

a = r(sy/sx)

The calculation of a standard deviation involves taking the positive square root of a non-negative number. As a result, both standard deviations in the formula for the slope must be nonnegative. If we assume that there is some variation in our data, we will be able to disregard the possibility that either of these standard deviations is zero. Therefore the sign of the correlation coefficient will be the same as the sign of the slope of the regression line.
