The ratio of the given expression is equal to 1:16.

Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.

We apply the concepts of ratio and proportion every day, for example, while dealing with money in business or when preparing any meal, etc. Sometimes, pupils struggle to understand the relationship between ratio and proportion.

We have x=1 and y=2, and we have to find the ratio of x4:y4,

Answer:

Y = -2,  X = 4

Step-by-step explanation:

When you first use the elimination method, you would multiply 2x-y = 10 by -2 so that you could get the 4x to be eliminated.

4x-3y = 22

(2x-y = 10)-2 = -4x + 2y = -20

When you add those 2 together you are left with -y = 2, which you divide by negative to get y = -2. Then you substitute -2 for y to solve for x. I substituted the bottom equation

2x - (-2) = 10

2x +2 = 10

2x = 8

Divide both sides by 2 to get x = 4.

Answer:

730 1/3

Step-by-step explanation:

It should be written as:

2(a+b)+ (a+b)/6+(a+b)^2-2, so that the quantity a + b is divided by 6 and not just b.

Hence, we have that

​2(a+b)+ (a+b)/6+(a+b)^2-2 =

2(26) + 26/6 + 26^2 - 2 =

52 + 13/3 + 676 - 2 =

The value of 'a' in the expression \(a + 3\frac{1}{4} = 5\frac{2}{9}\) is equal to \(36\frac{35}{36}\).

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, \(a + 3\frac{1}{4} = 5\frac{2}{9}\).

a + 13/4 = 47/9.

a = 47/9 - 13/4.

a = {(47×4) - (13×9)}/36.

a = (188 - 117)/36.

a = 71/36.

The real roots of the equation x⁴ −6x² +5=0 are -√5, √5, -1 and 1.

Given equation is x⁴ −6x² +5=0

To find the roots of the given equation by factoring method:

First, Let y=x²

Therefore, the equation becomes: y² -6y +5=0

Factorizing the above equation, we get:(y-5)(y-1)=0

From the above equation, we get two values of y: y=5, y=1

When y=5, x²=5 taking square root on both sides we get x= ±√5

When y=1, x²=1 taking square root on both sides we get x= ±1

Hence the real roots of the equation x⁴ −6x² +5=0 are -√5, √5, -1 and 1.

In the comma-separated list, the answer is -√5, 1, √5, -1.

The rate of change of the country's GDP 3 years from now is $10 billion/yr, based on the differentiation of the GDP function with respect to time.

To find the rate of change of the country's GDP 3 years from now, we need to differentiate the GDP function N(t) with respect to t and evaluate it at t = 3.

Given:

N(t) = t^2 + 4t + 400

Differentiating N(t) with respect to t:

N'(t) = 2t + 4

Evaluating N'(t) at t = 3:

N'(3) = 2(3) + 4

N'(3) = 6 + 4

N'(3) = 10 billion/yr

Therefore, the rate of change of the country's GDP 3 years from now is $10 billion/yr.The rate of change of the country's GDP 3 years from now is estimated to be $10 billion per year. This is determined by differentiating the GDP function N(t) with respect to time, which results in 2t + 4. Evaluating this expression at t = 3 yields a rate of change of 10 billion/yr.

We need to use some basic algebraic equations. Let's assume that the initial payment made by Frankie was x, and the total amount he has to pay for the computer is y. Also, let's assume that Frankie will make n monthly payments.

Now, we know that Frankie has already paid x, and he has to pay y-x more. Since he will pay this amount in n monthly installments, we can represent the monthly installment as (y-x)/n.

So, the equation that represents the relationship between n and y can be written as:

y = x + n*(y-x)/n

Simplifying this equation, we get:

y = x + y-x

y = y

This means that the equation is true for any value of n and y, as long as x is a valid initial payment amount. Therefore, the equation that represents the relationship between n and y is:

y = x + n*(y-x)/n

The equation we derived above is a simple but important concept in mathematics and finance. It shows us that we can calculate the total amount we need to pay for something by multiplying the monthly installment by the number of payments and adding the initial payment to it. This concept is used in many financial transactions, such as car loans, mortgages, and credit card payments.

Moreover, this equation also helps us to plan our finances and manage our budget effectively. We can use it to calculate how much we need to save every month to reach our financial goals, or to compare different payment options and choose the one that suits us best.

In conclusion, the equation that represents the relationship between the number of monthly payments and the total amount paid is an essential tool for anyone who wants to make wise financial decisions. By understanding this equation, we can save money, avoid debt, and achieve our financial goals more easily.

A line with positive slope is always perpendicular to a line with negative slope, since perpendicular slopes (of non horizontal and non vertical lines) are opposite signs and reciprocals.

So, you have to be perpendicular to the red line, since that's the one with a negative slope.  Since the slope of the red line is "down 5, right 1" or -5/1 (found by getting from the y-intercept to the x-intercept), your line's slope is the opposite sign and reciprocal.

That makes your slope positive 1/5.

There are 1854 permutations of the set {1, 2, ..., 14} in which exactly 7 integers are in their natural positions.

In the hypercube Q3, the vertex 000 is involved in 3 4-cycles.

To explain this:In a hypercube Qn, each vertex is connected to exactly n other vertices that differ by only one bit. A 4-cycle is a path that includes 4 vertices and 4 edges. So to count the number of 4-cycles that the vertex 000 is involved in, we need to count the number of other vertices that differ from 000 by exactly 2 bits.

There are three vertices that satisfy this condition: 001, 010, and 100. Each of these vertices can be paired with one of the two remaining bits to form a 4-cycle, so the total number of 4-cycles involving the vertex 000 is 3*2 = 6.There are 14 integers in the set {1, 2, ..., 14}.

To determine the number of permutations of this set in which exactly 7 integers are in their natural positions, we can use the formula for derangements: !n = n!(1/0! - 1/1! + 1/2! - 1/3! + ... + (-1)ⁿ/n!).

Here n = 7, so !n = 7!(1/0! - 1/1! + 1/2! - 1/3!) = 1854.

The equation that relates x and y is xy = 12. The solution has been obtained by using proportions.

What is proportion?

Two numbers are compared. It is known as a proportion in mathematics. The law of proportion states that if two sets of given numbers rise or decrease in the same ratio, they are considered to be directly proportionate to one another. Else, they are inversely proportion.

We are given that y varies inversely as x.

This implies that

⇒y ∝ 1/x

⇒xy = k

We are given when x = 5, y is 2.4. So, we get

⇒5 * 2.4 = k

⇒k = 12

Thus, we get xy = 12.

Hence, the equation that relates x and y is xy = 12.
