Not sure if this is 100% correct Sowwie

The angles formed by parallel lines a, b, and c, indicates that the correct option is the option C

C. x = 120, y = 70

Parallel lines are lines that that maintain a particular distance between each other, such that they have the same slope, and they do not meet, or intersect

The rays a, b, and c are parallel, therefore;

Angle x° and the 120° angle are corresponding angles;

x° = 120° (Corresponding angles formed between parallel lines are congruent)

The external angle theorem indicates;

x° = y° + 50°

Therefore, 120° = y° + 50° (Substitution property)

y° = 120° - 50° = 70°

The correct option is the option C. x = 120, y = 70

If  a//b//c are parallel lines with a transversal passing through these line. Angle x= 120° and y = 70°.Option C

As far as parallel lines are concerned, Corresponding angles are equal when when a transversal passes through two parallel lines.  Alternate interior angles are equal too.

We can therefore say that x is 120°.

b is a straight line which is 180°

if x = 120 the remaining length of the diameter is 60°

Therefore to solve for y ⇒ 50° + 60° = 110°

The sum of the interior angles of a triangle is 180°

∴ 180° - 110° = 70

y = 70°

Answer:

Step-by-step explanation:

equation is : C=2πr

\( \Large \underline{\tt Given} :\)

\( \\ \)

\( \Large \underline{\tt To \: Find} :\)

\( \\ \)

\( \Large \underline{\tt Solution} :\)

As, we have diameter of circle is 5.6 cm and radius is half of diameter.

\( \tt : \implies Radius, r = \dfrac{d}{2}\)

\( \tt : \implies Radius, r = \dfrac{5.6 \: cm}{2}\)

\( \tt : \implies Radius, r = \dfrac{\cancel{56} \: cm}{10\times \cancel{2}}\)

\( \tt : \implies Radius, r = \dfrac{28 \: cm}{10}\)

\( \tt : \implies Radius, r = 2.8 \: cm\)

\( \\ \)

Now, for Circumference :

\( \Large \underline{\boxed{\bf{Circumference = 2\pi r}}}\)

\( \tt : \implies Circumference = 2 \times \dfrac{22}{7} \times 2.8 \: cm\)

\( \tt : \implies Circumference = \dfrac{44}{\cancel{7}} \times \dfrac{\cancel{28}}{10} \: cm\)

\( \tt : \implies Circumference = 44 \times \dfrac{4}{10} \: cm\)

\( \tt : \implies Circumference = \dfrac{176}{10}\: cm\)

\( \tt : \implies Circumference = 17.6\: cm\)

\( \\ \)

Hence, circumference is 17.6 cm.

If the spinner is spun 400 times, it is expected  to land 200 times on an odd number.

The spinner has 4 equally likely outcomes, with 2 of them being odd numbers (1 and 3). Therefore, the probability of landing on an odd number is 2 out of 4, or 1/2.

If the spinner is spun 400 times, we can expect it to land on an odd number 400 * 1/2 = 200 times. This is because the number of times the spinner lands on an odd number follows a binomial distribution with n = 400 and p = 1/2, where n is the number of trials and p is the probability of success (landing on an odd number). The expected value of this binomial distribution is n * p, which is equal to 400 * 1/2 = 200.

Answer:

Step-by-step explanation:

39*34= 1326 (the area of the full square

8*10=80 (the area of the small square that is cut off)

1326-80= 1246

Answer:

C = 1246 sq. cm.

Step-by-step explanation:

finding the area is simply splitting the area into two (see image)

A1 = 26 x 39 = 1014

A2 = 8 x 29 = 232

total area = 232 + 1014

total area = 1246 sq. cm.

therefore, the answer is C = 1246 sq. cm.

Step-by-step explanation:

The length of the hypotenuse is z = √(23² + 12²) and the length of the other side is y = 12z. is the answer.

Consider a right triangle with a side of length x opposite angle A, a side of length y opposite angle B, and a hypotenuse of length z opposite the right angle.

If sinB= 12 and x=23, then we can find the length of the other side (y) and the length of the hypotenuse (z) using the following method: We have, sinB = 12, and B is the angle opposite the side y.

Using the sin ratio, we have: sinB = y/z

We are given the value of sinB as 12.

Substituting this value in the above equation, we get:12 = y/z

This means that y = 12zWe are also given x=23.

Using the Pythagoras theorem, we have:x² + y² = z²

Substituting the value of y from above, we get:23² + (12z)² = z²

Solving for z, we get: z = √(23² + 12²)

Therefore, the length of the hypotenuse is z = √(23² + 12²) and the length of the other side is y = 12z.

Step-by-step explanation:

Answer:

\( \sf \: x = 5\)

Step-by-step explanation:

Given equation,

→ 3(2x - 7) = 5 - (1 - x)

Now the value of x will be,

→ 3(2x - 7) = 5 - (1 - x)

→ 6x - 21 = 5 - 1 + x

Two variables that are linearly connected have a consistent rate of change since a line's slope is unique.

The slope of a line, which shows the rate of change between two variables, is determined by dividing the change in one variable's value by the change in the other variable's value. A straight line can be used to depict the relationship between two variables when they are linearly related, and the slope of the line indicates how quickly the variables are changing.

Since no two lines have the same slope, the rate of change of two variables with linear relationships is constant and remains constant.

Explanation: If all the diagonal entries of a square matrix are zero, then we can use the Laplace expansion along the first column to calculate the determinant. The Laplace expansion states that the determinant of a matrix A can be calculated by multiplying the entries of any row or column of A by their corresponding cofactors and then adding up these products.

Since all the diagonal entries of our matrix are zero, we can focus on the first column. The first entry of the first column is zero, so we don't need to consider it. For the second entry, we need to multiply it by its corresponding cofactor, which is the determinant of the (n-1)x(n-1) matrix obtained by deleting the second row and second column of the original matrix. But since all the diagonal entries of this smaller matrix are also zero, we can repeat the process and use the Laplace expansion along the second column.

Continuing in this way, we eventually reduce the problem to calculating the determinant of a 1x1 matrix, which is just its single entry. But since all the entries of our original matrix are zero, the determinant is also zero. Therefore, if all the diagonal entries of a square matrix are zero, then the determinant of that matrix must also be zero.

Step-by-step explanation:

The colorimeter detects the voltage created when sunlight penetrates the specimen, so the voltage created is exactly proportional to the absorbance of the sample.

When charged electrons (current) are forced through a conducting loop by the weight of an electrical raceway power source, they can perform tasks like lighting a lamp. In a nutshell, voltage equals pressure and is expressed in volts (V).

Here,

The voltage generated by the uv spectrophotometer is inversely proportionate to the amount of light present and linearly proportional to the sample's absorbance.

This indicates that as the sample's absorbance rises, so does the energy the colorimeter generates.

Similar to this, the voltage generated by the colorimeter rises as light strength falls.

The Beer-Lambert Law, which says that a sample's absorbance is directly proportional to its concentration of the absorbing substance and its path length and inversely proportional to incident light intensity, describes this connection.

The colorimeter detects the voltage created when sunlight penetrates the specimen, so the voltage created is exactly proportional to the absorbance of the sample.

Step-by-step explanation:

The sum of the angles in a triangle is always 180 degrees. Therefore,

2x + 3x + 22 = 180

Simplifying the equation,

5x = 158

Dividing by 5 on both sides,

x = 31.6

To find the actual measures of 2x and 3x, we substitute the value of x:

2x = 2(31.6) = 63.2 degrees

3x = 3(31.6) = 94.8 degrees

Therefore, the actual measures of 2x and 3x are 63.2 degrees and 94.8 degrees, respectively.

The position of point A of the triangle is -4 units from the x-axis.
