What is ratio?

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other.

The first table is -

Column 1   Column 2

2                  36

4                  48

5                  60

6                  72

Reduce the column 1 and column 2 values to its simplest form to get the ratio.

The ratio values are for row 1 - 1:18, row 2 - 1:12, row 3 - 1:12 and row 4 - 1:12.

So, row 1 has different ratio than other three rows.

The second table is -

Column 1   Column 2

2                  22

3                  39

4                  48

Reduce the column 1 and column 2 values to its simplest form to get the ratio.

The ratio values are for row 1 - 1:18, row 2 - 1:13, row 3 - 1:12 and row 4 - 1:12.

So, row 1 has different ratio and row 2 has different ratio than other two rows.

The third table is -

Column 1   Column 2

2                  24

5                  60

6                  72

7                  84

Reduce the column 1 and column 2 values to its simplest form to get the ratio.

The ratio values are for row 1 - 1:12, row 2 - 1:12, row 3 - 1:12 and row 4 - 1:12.

So, all rows have same ratios.

The fourth table is -

Column 1   Column 2

2                  28

3                  36

4                  48

6                  72

Reduce the column 1 and column 2 values to its simplest form to get the ratio.

The ratio values are for row 1 - 1:14, row 2 - 1:12, row 3 - 1:12 and row 4 - 1:12.

So, row 1 has different ratio than other three rows.

A ratio of two integers where the denominator is not 0 is a valid ratio.

What is denominator ?

A denominator is the number that appears below the line (or fraction bar) in a fraction, such as a/b. It is the number that is being divided by the numerator, which is the number that appears above the line. The denominator can be any number, including negative numbers, zero and fractions.

A ratio of two integers where the denominator is not 0 is a valid ratio. Ratios are used to compare the size of two or more quantities and are written as a:b or a/b, where a and b are integers. The denominator is the number on the bottom of the fraction and it should not be zero, as it would create an undefined value. When the denominator is not zero, the ratio can be simplified or used to compare the size of the two integers.

Factoring, utilizing square roots, completing the square, and the quadratic formula are the four ways for solving a quadratic equation.

To factor a quadratic equation, do the following:

1. In standard form, transform the equation such that one side is zero.

2. Take into account the non-zero side.

3. Make each component equal to zero (Remember: a product of factors is zero if and only if one or more of the factors is zero).

4. Solve each of the resultant equations.

Factoring cannot solve all quadratic problems. For example, x²- 3x = 3 cannot be solved using this approach. Completing the square is one approach for solving quadratic equations; graphing the result is another.

Answer:

  18

Step-by-step explanation:

You want the number of vertices such that the number of pairs of vertices is 153.

The number of n objects taken 2 at a time is ...

  N = (n)(n -1)/2

You want to find n for N=153.

We notice that multiplying by 2 gives a near square:

  2N = n(n -1)

The square root of this will have a value approximately equal to n-1/2:

  n -1/2 ≈ √(2·153) = √306 ≈ 17.5   ⇒   n = 18

We can check this:

  (18)(17)/2 = 9·17 = 153

The mystic rose with 153 lines has 18 vertices.

__

Additional comment

We could solve the quadratic equation 306 = n(n-1) by any of several means. The method used here is about the fastest.

If you want to get formal about solving the equation this way, you can define z = n-1/2, then the equation becomes ...

  306 = (z +1/2)(z -1/2) = z² -1/4

  306.25 = z²   ⇒   z = 17.5   ⇒   n = 18

By leaving off the 0.25 addition to 306, the root we get is slightly low, but still close enough to 17.5 to show us what the answer is.

Answer:

The equation of a straight line passing through the origin can be written in the form y = mx, where m is the slope of the line. To find the equation of a line that is perpendicular to a given line, we need to find the negative reciprocal of the slope of the given line.

A line that is perpendicular to a line with the equation ax²-2hxy-by², we can find the slope of the given line by taking the derivative with respect to x.

The slope of the line is -2hy/ax.

The negative reciprocal of this slope is ax/2hy.

So the equation of the line perpendicular to ax²-2hxy-by² and passing through the origin is y = ax/2hy * x.

Note that if a = 0, the line is parallel to Y-axis and if b = 0, the line is parallel to X-axis.

Step-by-step explanation:

The down payment is 400, the monthly payment is 65 and the length of the plan is 7 months. An arithmetic sequence is a sequence of numbers such that the difference between any two consecutive numbers is constant.

Arithmetic refers to the branch of mathematics that deals with numbers and the basic operations of addition, subtraction, multiplication, and division. An arithmetic sequence is a specific type of mathematical pattern where each term is obtained by adding a constant value to the previous term.

Here is the way to determine the monthly payment:

(1,060 - 400) / 7 = (660) / 7 = 65

As you can see the down payment is 400 and the last value in the sequence is 1060, so the total amount of the plan is 1060.

Also, the difference between any two consecutive terms is 110, as we can see that from the sequence:

510 - 400 = 110

620 - 510 = 110

730 - 620 = 110

840 - 730 = 110

950 - 840 = 110

1060 - 950 = 110

So the length of the plan is 7 months as the sequence contains 7 terms.

The range of the function is (0, 30), which represents the possible values of the boat's value in thousands of dollars.

An equation is a mathematical statement that uses symbols, numbers, and/or variables to represent a relationship between two or more quantities. It usually contains an equal sign, indicating that the expressions on both sides of the equal sign have the same value. Equations are used to solve problems and find unknown values by manipulating the symbols and solving for the variable.

Here,

The given graph does not represent an exponential function as the values of y do not increase or decrease at a constant rate. However, we can approximate the values and find an exponential function that fits the data points closely.

Using the two given points (0, 30) and (1, 24), we can find the base of the exponential function as follows:

y = abˣ

30 = ab⁰ (at x=0, y=30)

24 = ab¹ (at x=1, y=24)

Dividing the second equation by the first, we get:

24/30 = (ab¹)/(ab⁰)

0.8 = b

Now we can substitute the value of b in one of the equations to find a:

30 = a(0.8)⁰

a = 30

So the exponential function that fits the data points closely is:

y = 30(0.8)ˣ

The y-intercept of this function is 30, which means that the initial value of the boat is $30,000.

The number of different ways the medals can be awarded is (finalists) * (finalists -1) / 2.

We have two medals (gold and silver) and "n" finalists. The question asks for the number of ways the medals can be awarded.

This is a combination problem, where we have to select 2 items (medals) out of n items (finalists) without regard to the order.

The number of ways to select k items out of n items without regard to the order is given by the binomial coefficient (n choose k), which is calculated as:

nCk = n! / (k!(n-k)!)

where n is the total number of items, k is the number of items selected and ! denotes factorial.

So, in this problem, we have to calculate the number of ways to select 2 medals out of n finalists, the binomial coefficient is:

nC2 = n! / (2!(n-2)!) = n*(n-1)/2

When the polynomial 2x³ - 3x² + 4x + 7 is divided by x - 2 we get the remainder 19.

The given polynomial is 2x³ - 3x² + 4x + 7.

First we choose a term to multiply with the first term of the divisor such that we get the first term of the polynomial:

(x)(2x^2) = 2x^3

Thus, we multiply the divisor (x-2) by 2x^2 which gives 2x^3 - 4x^2

Now we subtract this from the polynomial which gives x^2 + 4x + 7.

Next we multiply the divisor by x which gives x^2 - 2x. Subtracting the same from x^2 + 4x + 7 we get 6x + 7.

The error is in the 3rd step.  The denominator should be 3, not -1.

Step-by-step explanation:

The third step has an error.  The second fraction is subtracted from the first.  The calculation should have been (x+1) - (x-2).  x+1-x+2 = 3.
