How do you graph y =- 7?.

Answer:

190,217

Step-by-step explanation:

Let x = number of doctors.

27.6% of x is 52,500

0.276x = 52,500

x = 52,500/0.276

x = 190,217

The value of n in the equation n/5 + 0.6 = 2 is 7.

It should be noted that an equation simply has to do with the statement that illustrates the variables given. In this case, it is vital to note that two or more components are considered in order to be able to describe the scenario.

It is important to note that an equation is the mathematical statement which can be made up of two expressions which are connected by an equal sign.

In this case, n/5 + 0.6 = 2

0.2n + 0.6 = 2

Collect the like terms

0.2n = 2 - 0.6

0.2n = 1.4

Divide

n = 1.4 / 0.2

n = 7

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.

Algebraic expressions called polynomials include coefficients and variables. Indeterminates are another name for variables. For polynomial expressions, we can do mathematical operations like addition, subtraction, multiplication, and positive integer exponents but not division by variables. x2+x-12 is an illustration of a polynomial with a single variable.

There are three terms in this example: x2, x, and -12.

Given:

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.

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.

We know that the average price of a gallon of milk in 2000 was $2.78 and that it increased by about $0.11 per year. To find the years in which the price of a gallon of milk is between $3 and $4, we can use the following inequality:

2.78 + 0.11y < x < 4

Where x is the price of a gallon of milk in a given year y, and y represents the number of years since 2000.

The inequality can also be written as:

2.78 + 0.11y < x < 4

That can be simplified as

y > (3-2.78) / 0.11 = (0.22) / 0.11 = 2

y < (4-2.78) / 0.11 = (1.22) / 0.11 = 11

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

The linear equation perpendicular to the line y = 1/2x - 4 is:

y = -2x + 25

A general linear equation can be written as:

y = m*x + b

Where m is the slope and b is the y-intercept.

And two lines are perpendicular if the product between the slopes is -1, then if we want to find a line perpendicular to:

y = 1/2x - 4

Then the slope m must be sch that:

m*(1/2) = -1

m = -2

Then the line is like:

y = -2*x + b

And we know that this passes through (10, 5), replacing these values:

The ant population increases by factor of 5 every week. After 3 weeks, there will be 800 ants in the farm.

The problem can be solved by considering the ant population growth as a geometric sequence.

In a geometric sequence, a term is obtained by multiplying the previous term by a constant, which is called a common ratio. We can consider this common ratio as a growth factor.

In this case, the common ratio = 5

week 1 = 32 ants

week 2 = 32 x 5 ants = 160 ants

week 3 = 160 x 5 ants = 800 ants

We can also find the number of ants using the geometric sequence formula for the nth term:

Let the cost of bottles of water = b and the cost of slices of pizza = p

Equation 1: 5b + 8p = 20.25

Equation 2: b + 3p = 6.50

Multiply Equation 2 by 5:

Equation 3: 5b + 15p = 32.50

Subtract Equation 1 from Equation 3:

5b + 15p = 32.50

p = 1.75

The cost of one slice of pizza (p) = $1.75

Check:

b + 3p = 6.50

b + 3(1.75) = 6.50
