By using Pythagoras theorem, Kyle run for the distance of 210 m.

What is the Pythagorean theorem ?

According to Pythagoras's Theorem, the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides.

                                  Perpendicular, Base, and Hypotenuse are the names of this triangle's three sides.

The given length of the field is 84 m.

And, the width is 35 m.

Now, the diagonal of the field can be calculated using Pythagoras theorem as below,

Diagonal = √((84)² +(35)²)

              = 91

Then, the total length is found by summing the length, width and the diagonal as below,

= 84 + 35 + 91

= 210

Hence, Kyle run for the distance of 210 m.

Answer:

YEEAH bro its called a graph you should try it

Step-by-step explanation:

Answer:

  4x -10

Step-by-step explanation:

You want the side length of a square whose perimeter is (16x -40) feet.

The four sides of a square are all the same length. The perimeter is the sum of those lengths, so is 4 times the side length. Conversely, the side length is 1/4 of the perimeter.

  s = P/4 = (16x -40)/4

  s = 4x -10

The side length of the square table is 4x -10 feet.

Answer: 19.5

Step-by-step explanation:

obtuse + acute = 180

131 + t = 180

t = 49 degrees for the top angle

49 + 61 + 4x-8 = 180 degrees in a triangle

110 + 4x - 8 = 180

102 + 4x = 180

4x = 78

x = 19.5

Answer:

x = 19.5

Step-by-step explanation:

The interior angles of a triangle will ALWAYS have a sum of 180°

Answer:

To find out how much Laura earns each week, you can set up an equation using the information given. Let's call Laura's weekly pay "W".

You know that Laura has saved 5 times her weekly pay, so you can write this as 5W.

You also know that she spent less than 2 times her weekly pay this week, so you can write this as 2W - X, where X is the amount that she spent less than 2 times her weekly pay.

Finally, you know that she has 156 left after spending some money, so you can write this as 156.

You can now set up the equation:

5W + (2W - X) = 156

Combining like terms, you get:

7W - X = 156

Adding X to both sides, you get:

7W = 156 + X

Dividing both sides by 7, you get:

W = (156 + X) / 7

Thus, Laura's weekly pay is equal to (156 + X) / 7. You know that she spent less than 2 times her weekly pay this week, so X must be less than 2W. However, you don't know the exact value of X, so you can't find the exact value of Laura's weekly pay.

If laura has saved her babysitting money for the past two weeks then Laura earns 52 dollars per week.

Two or more expressions with an Equal sign is called as Equation.

Let Laura earns x dollars per week.

According to the problem, after two weeks of saving, she has 5 times her weekly pay, which means she has saved 5x dollars.

This week, she spent less than 2 times her weekly pay, which means she spent less than 2x dollars.

Now, she has 156 dollars left, so we can set up the equation:

5x -  2x = 156

Simplifying this equation, we get:

3x= 156

Divide both sides by 3

x = 52

Hence, Laura earns 52 dollars per week.

Inequality (A) "y > x-2 represents the given graph when the line passes to 2 and -2 from the x-axis and y;-axis respectively.

In discrete mathematics, more specifically in graph theory, a graph is a structure that resembles a collection of objects where some object pairs are conceptually "connected."

Each pair of connected vertices is referred to as an edge, and the objects are represented by mathematical abstractions known as vertices.

To calculate the slope m and the y-intercept, write the equation y = MX + b.

The slope and y-intercept can then be used to graph the equation (0, b).

So, to find which inequality represents the given graph, simply plot the inequalities on the graph.

After plotting, we can conclude that inequality "y > x-2" represents the graph shown in the question.

52×7 = 50×7 + 2×7

why?

because 52 = 50 + 2

so,

52×7 = (50 + 2)×7 = 50×7 + 2×7

Answer

The third option 52 x 7 = 50 x 7 + 2 x 7

Step-by-step explanation:

First of 52 x 7 = 364, so whichever other equation is equal to 364 is the correct option

50 x 7 + 2 x 7

350 + 2 x 7

The concentration of H+ ions at a pH = 2 is 10⁻² mol/L

Theconcentration of H+ ions at a pH = 6 is 10⁻⁶ mol/L

And there are 10,000 times more H⁺ ions in a solution of pH = 2 than that of pH = 6

In this question we have been given the pH of the solution.

We need to find the concentration of H+ ions in the given solution.

The H⁺ ion concentration can be calculated from pH values using the equation: pH = - log [H⁺]

at a pH = 2,

Using the above equation, 2 = - log [H⁺]

[H⁺] = 10⁻² mol/L

at a pH = 6,

Using the above equation, 6 = - log [H⁺]

[H⁺] = 10⁻⁶ mol/L

We need to find how many more h ions are there in a solution at a ph = 2 than in a solution at a ph = 6

Consider the ratio of [H⁺] for pH = 2 and pH = 6, we have

10⁻²/10⁻⁶ = 10⁴

Therefore,  there are 10,000 times more H⁺ ions in a solution of pH = 2 than that of pH = 6

The ratio of volumes of Cylinder A to Cylinder B is 1 : 2

What is a Cylinder?

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of Cylinder = πr²h

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

Let the volume of the first cylinder be = A

Let the volume of the second cylinder be = B

Now,

The diameter of first cylinder = 7 cm

Radius of the first cylinder r = 7/2 = 3.5 cm

Height of the first cylinder h = 14 cm

And ,

The diameter of second cylinder = 14 cm

Radius of the second cylinder R = 14/2 = 7 cm

Height of the second cylinder H = 7 cm

To find the ratio between the volumes of both cylinders

Volume of Cylinder A = πr²h

Substituting the values in the equation , we get

Volume of Cylinder A = π x ( 3.5 ) x ( 3.5 ) x ( 14 )

Volume of Cylinder B = πR²H

Substituting the values in the equation , we get

Volume of Cylinder B = π x ( 7 ) x ( 7 ) x ( 7 )

The ratio between volumes of A and B is given by = Volume of Cylinder A / Volume of Cylinder B

So , the ratio is

Volume of Cylinder A / Volume of Cylinder B = π x ( 3.5 ) x ( 3.5 ) x ( 14 ) /  π x ( 7 ) x ( 7 ) x ( 7 )

On simplifying the equation , we get

Volume of Cylinder A / Volume of Cylinder B = 2/4

Therefore , the ratio is

Volume of Cylinder A / Volume of Cylinder B = 1 : 2

Hence , The ratio of volumes of Cylinder A to Cylinder B is 1 : 2

If a figure is dilated by a scale factor of 10, the area of the figure will change by a factor of 100.

The size of a two-dimensional form or a region in a plane is described by the mathematical notion of area. Square units like square inches, square feet, or square metres are frequently used figure to measure it. The total space a form takes up in a plane is known as its area. The length and breadth of the shape may be multiplied to compute it, or intricate forms like circles, triangles,  formulae can be used. Finding the dimensions of a form, calculating area ofcircle or rectangle, or  area of three-dimensional object are just a few of the many issues that may be solved using the geometry concept of area.

How to solve?

If a figure is dilated by a scale factor of 10, its area will change by a factor of 100.

When a figure is dilated, its area changes by the square of the scale factor. In this case, the scale factor is 10, so the area will change by a factor of 10^2 = 100.
