How do you find the mode in maths class 7?.

Answer: 24.2

Step-by-step explanation: Use the Pythagorean Theorem:

10^2 + 22^2 = x^2

100 + 484 = x^2

x^2 = 584

x = 24.16609..

which is close to 24.2

Answer: 24.2

Step-by-step explanation:

Use the Pythagorean Theorem.

[tex]a^2 + b^2 = c^2[/tex]

We already know a and b.

We can plug it in into the theorem.

[tex]10^2 + 22^2 = c^2[/tex]

[tex]584 = c^2[/tex]

Then, take the square root of 584.

[tex]\sqrt{584}[/tex] ≈ 24.2 (24.16 rounded up is 24.2)

The equation 6x + 7 = 2(3x + 5) + 9 has no solution.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Let's solve the equation for variable x.

A variable is a number represented with letter in an equation. Therefore,

6x + 7 = 2(3x + 5) + 9

6x + 7  = 6x + 10 + 9

6x + 7 = 6x + 19

6x - 6x = 19 - 7

0x = 12

Therefore, the equation cannot be solved.

Answer:

1 1/2

Step-by-step explanation:

The equation in the said case is 10x + 5 = 35

Tickets bought = 10

Parking fee paid = $5

Money spent on seeing the show = $35

Determining the equation in the given case -

10x + 5 = 35

Where x is the cost of each ticket, and 10x represents the total cost of the tickets.

The equation states that the total cost of the tickets which is 10x plus the cost of the parking fee which is $5 is equal to the total amount spent by Kate which will be 35$.

This equation can be further used to find the cost of each ticket by isolating x:

10x + 5 = 35

10x = 30

x = 3

Therefore, each ticket cost $3.

The horizontal asymptote of the graph is the horizontal line y = b and the graph approaches a straight line as the input approaches ∞ or −∞.

Horizontal Asymptote: As x moves towards infinity or -infinity, the curve approaches a constant value b, called a horizontal asymptote with equal numerator and denominator. The following are used to determine the horizontal asymptotes:

For example, function f(x) = 2x / (x - 3) and we have to determine the horizontal asymptotes. As we see the degree of polynomials both in numerator and denominator is equal. So, horizontal asymptotes is equal to number which is obtained by dividing the hightest degree coefficients i.e., 2/1 = 2. Thus, the function has only one horizontal asymptote which is y = 2. Here is the graphical verification.

The earthquakes with the greatest magnitude do not always cause the highest number of death because other factors like area ( ground, water , sand etc.), soil structure, buliding constutor material etc. also affect the earthquake intensity.

The biggest earthquakes are not necessarily the most devastating ones. But other factors are also involved here. In areas of water-saturated sand, shaking loosens the sand particles from each other, causing them to "float" on the water and turn into quicksand. Sand at rest is still and hard, but when shaken it forms liquid mud. Buildings and other structures built on such sand simply sink and collapse. Other types of soil structures and terrain can amplify and resonate seismic waves, potentially causing more damage. Of course, if an earthquake occurs at sea, it can create a devastating tsunami. Also, certain structures and buildings are less susceptible to vibration than others due to how they are constructed and the materials used. For example, a large magnitude 9.0 earthquake might cause minor damage due to its remote location. But if 6.0 occurs in an underdeveloped and densely populated area, it could kill thousands.

The more people there are, the more people die. For example, the 2001 earthquake in India occurred in a densely populated area.

By using the area of the square formula, it can be concluded that the side of the square shed is 6 meters.

The area of a square or a rectangle can be defined as the number of square units needed to fill it.  

Area of a Square = side × side = side²

Area of a rectangle = width x length

Area of the square = area of the rectangle

Rectangle width = 3 meter

Rectangle length = 12 meter

To find the side of the square shed, we can do the following:

Area of the square = Area of the rectangle

                      side² = width x length

                               = 3 x 12

                               = 36

                       side = √36

They are the set of numbers and symbols that are related by the different mathematical operation signs such as addition, subtraction, multiplication, division among others.

To solve this problem we must perform the following algebraic operations with the given information

Information about the problem:

Calculating the days from 08/21/2019 to 08/21/2022, we get:

Days 1 = (08/21/2022 - 08/21/2019) * (365 days/1 year)

Days 1 = 3 years * (365 days/1 year)

Days 1 = 1095 days

Calculating the days from 05/21/2019 to 08/21/2019, we get:

Days 2 = (08/21/2019 - 05/21/2019) * (30 days / 1 month)

Days 2 = 3 month * (30 days / 1 month)

Days 2 = 90 days

Calculating the days from 05/20/2019 to 05/21/2019, we get:

Days 3 = 05/21/2019 - 05/20/2019

Days 3 = 1 day

Calculating the total days from 08/21/2019 to 05/20/2022, we get:

Total days = Days 1 - days 2 - days 3

Total days = 1095 days - 90 days - 1 day

The slope of the given equation is -3/2.

The equation of a line in the form 3x + 2y = 8 is not in the standard form of a linear equation, also known as slope-intercept form. In order to find the slope of the line, we need to express the equation in the form y = mx + b, where m is the slope of the line and b is the y-intercept.

To do this, we can start by isolating y on one side of the equation. We can subtract 8 from both sides, resulting in 3x + 2y -8 = 0.

Next, we can divide both sides by 2, which gives us (3/2)x + y - 4 = 0. This is the equation in the slope-intercept form.

The slope of the line is represented by the coefficient of x, which in this case is (-3/2). It tells us that for every 1 unit increase in x, the value of y will decrease by 3/2 units.
