The value of x in equation 2x+3y=36, when y=6 is 9.

The replacement operation can be used in a variety of situations involving formal objects that contain symbols; it involves systematically replacing occurrences of a symbol with a particular value.

Substitution is a fundamental computer algebra operation.

Given equation 2x+3y=36 ; y=6

Solve the equation for given y.

Plugging y=6 in the given equation

We get 2x + 3(6) = 36

2x +18 = 36

2x = 36 - 18

2x = 18

x = 9

Therefore, the value of x in equation 2x+3y=36, when y=6 is 9.

The distance between two points (2, 3) and (5, 7) is 5 units.

Therefore the answer is 5.

To find the distance between the points (2, 3) and (5, 7), we can use the distance formula:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

where (x₁, y₁) = (2, 3) and (x₂, y₂) = (5, 7)

Substituting the coordinates of the two points into the formula:

d = √((5 - 2)² + (7 - 3)²)

d = √((3)² + (4)²)

d = √(9 + 16)

d = √(25)

d = 5

So the distance between the points (2, 3) as well as (5, 7) will be  5 units by solving the above expression.

What is ratio ?

A ratio is a mathematical comparison of two or more values or quantities. It is a way of expressing the relationship between different amounts or measurements.

The ratio of running to dribbling is 5 minutes of running to 20 minutes of dribbling. We can use this ratio to find out how many minutes Bob spends running if he spends 36 minutes practicing dribbling.

First, we can set up a proportion with the known ratio and the unknown value ,

5/20 = x/36

To find x we can cross-multiply to get ,

20x = 180

then divide both sides by 20 ,

Yes 360 degrees is full turn calling it a full rotation.

A degree is the name given to the mathematical unit of measurement for an angle. A protractor is a device used to determine the degree of an angle. Angles can be measured at different angles with different degrees, such as 30°, 45°, 60°, and so on. A complete circle rotates at 360°.

Each of the 360 equal segments that make up a rotation is referred to as a degree. We use a circle ° to represent a degree. 180°, for instance, denotes 180 degrees. An angle in degrees is an angle whose measure is expressed in degrees.

A 360 degree is also called as a Complete angle because it complete the whole round making the 180 degree angle twice giving us 360 degree.

Amelia cut a 168 inch long ribbon into 6 equal part. Patrick cut a 14 foot long ribbon into 7 equal piece.

Amelia's ribbon pieces were 28 inches long each. Patrick's ribbon pieces were 2 feet long each.

Amelia's ribbon:

To calculate how long each piece of ribbon is, we need to divide 168 inches (the total length of the ribbon) by 6 (the number of pieces).

168 ÷ 6 = 28

Therefore, Amelia's ribbon pieces were 28 inches long each.

Patrick's ribbon:

To calculate how long each piece of ribbon is, we need to divide 14 feet (the total length of the ribbon) by 7 (the number of pieces).

14 ÷ 7 = 2

Since 1 foot is equal to 12 inches, we can convert 2 feet to 24 inches.

Therefore, Patrick's ribbon pieces were 2 feet (or 24 inches) long each.

Answer: We can use the formulas for conditional probability to calculate the percentage of people in the village who speak both French and English.

P(French and English) = P(French) x P(English|French)

We know that P(French) = 64% and P(English|French) is the probability of someone speaking English given that they already speak French, which is 58%. So we can plug these values into the formula:

P(French and English) = 64% x 58% = 37.12%

Therefore, 37.12% of the inhabitants of the village on the Nigerian border speak both French and English.

Note that this is an estimation since this formula assumes independence and the real probabilities might be different.

Step-by-step explanation:

The length of EF, to the nearest tenth of a foot is found to be 14.3 ft.

In rDEF, DE = 90°, DF = 81°, and DE = 14. 6 ft,

Because the given triangle is a right angled triangle, we can use the concepts of trigonometry in order to solve the given problem.

Using the trigonometric relation,

sin A = P/H

Where,

P is perpendicular and H is the hypotenuse.

We have, A = 81°,

It is given that the value of DE is 14.6 ft.

We know, sin(81°) = 0.98

So, the length of EF, to the nearest tenth of a foot is,

0.98 = EF/14.6

EF = 14.3 ft.

Answer: The Declaration of Independence, adopted by the Continental Congress on July 4, 1776, is a reflection of the colonists' motivations in several ways. Firstly, the Declaration states that the colonists believed that all men are created equal and have the right to life, liberty, and the pursuit of happiness. This reflects the colonists' belief in the Enlightenment principles of natural rights and individual liberty, which were influential in shaping their motivations for seeking independence from British rule.

Secondly, the Declaration cites a long list of grievances against King George III, accusing him of violating the colonists' rights and abusing his power. This reflects the colonists' growing frustration and anger towards British rule, which had been building for many years prior to the drafting of the Declaration.

Thirdly, the Declaration states that the colonists had attempted to resolve their differences with the British government through peaceful means, but that these efforts had been unsuccessful. This reflects the colonists' desire for a peaceful resolution to their issues, but their willingness to fight for their rights if necessary.

In summary, the Declaration of Independence reflects the colonists' belief in natural rights and individual liberty, their growing frustration and anger towards British rule, and their desire for a peaceful resolution to their issues but their willingness to fight for their rights if necessary.

D) The term "imaginary roots" describes the roots of the equation 3x2 - 4x + 5 = 0 the best.

The formula is the quadratic equation ax2 + bx + c = 0 in standard form.

x = [-b ± √(b2 - 4ac)]

/ 2a

It follows that

3x2 - 4x + 5 = 0

Here, an equals 3, b equals -4, and c equals 5.

Using these numbers as replacements in the formula

x = [-(-4) ± √((-4)2 - 4 × 3 × 5)]

By even more simplifying

x = [4 ± √(16 - 60)]

x = [4 ± √-44]/ 6

As a result,

x = [4 ± 2√-11]/ 6

x = [2 ± I √11]/ 3

What is the price of an item after a 30% discount if the original price of the item is 56 dollars?

Answer:

x = 79

Step-by-step explanation:

Since PQ and RS are most likely parallel lines, we can consider the orange angles (image provided below) to be similar due to them being alternate interior angles.

Now that we know that one angle of the triangle given (orange) is 46 degrees, we can solve for the other angle of the triangle. A triangle adds up to 180 degrees, so we can find the missing angle by subtracting 180 from the given angles: 180-33-46 = 101 (marked in red).

With the red angle, we can find x by subtracting 180 from 101. Why you may ask? Because RS is parallel to PQ, so the degree will be 180. Therefore, the missing angle, x, will be 79.

CB = 4√22/sin 90 × sin 45

CB = 4√11

or

CB = √(4√22)²-(4√11)²

= 4√11

Answer:

CB = AC = 4√11

Step-by-step explanation:

We know that the sum of the angles of a triangle is 180°. If angle A = 45° and C = 90°, then angle B = 180° - 90° - 45° = 45°. This shows us that the triangle is isosceles and the leg AC is equal to the leg CB.

Consequently: CB = AC = 4√11

If we didn't know the length of AC, then it can be calculated from the hypotenuse:

AC² + CB² = AB²
2 * CB² = (4√22)²
CB² = (4√22)² / 2
CB² = 16 * 22 / 2
CB = √(16 * 11)
CB = 4√11
