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.

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

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.

To solve the system of equations 2y + 5x = 13 and 2y-3x = 5 using the substitution method, you can follow these steps:

Begin by solving one of the equations for one of the variables. For example, you could solve the first equation for y:

2y + 5x = 13

2y = 13 - 5x

y = (13 - 5x) / 2

Substitute the expression for y into the second equation and solve for x:

2((13 - 5x) / 2) - 3x = 5

13 - 5x - 3x = 5

-8x = -8

x = 1

Substitute the value of x into the expression for y to find the value of y:

y = (13 - 5(1)) / 2

y = (13 - 5) / 2

y = 8 / 2

y = 4

The solution to the system of equations is (1,4).

The estimated probability that there will be more than 100 black bear cubs born in any given year is 41%. Option D. is the answer

Probability is the likelihood of a desired event happening.

Experimental probability is a probability that relies mainly on a series of experiments or past events

Given: from the table, the sum of the frequency for more than 100 cubs (i.e. 101-125, 126-150 and 151-175) is:

Sum of frequency of more than 100 = 24 + 10 + 7 = 41

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.

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be A

a)

4<7 Multiply both sides by 7 , then by 6, then by 3, then by 10

The inequality equation is A

The value of A is 4 < 7

Multiplying both sides by 7 , we get

28 < 49

Multiplying both sides by 6 , we get

168 < 294

Multiplying both sides by 3 , we get

504 < 882

Multiplying both sides by 10 , we get

5040 < 8820

Therefore , the inequality equation remains the same.

b)

11>-2 Add 5 to both sides, then add 3, then add (-4)

The inequality equation is A

The value of A is 11 > -2

Adding 5 on both sides , we get

16 > 3

Adding 3 on both sides , we get

19 > 6

Adding -4 on both sides , we get

15 > 2

Therefore , the inequality equation remains the same.

c)

-4<-2 Subtract 6 from both sides, then 8, and then 2

The inequality equation is A

The value of A is -4 < -2

Subtracting 6 on both sides , we get

-10 < -8

Subtracting 8 on both sides , we get

-18 < -16

Subtracting 2 on both sides , we get

-20 < -18

Therefore , the inequality equation remains the same.

d)

-8<8 Divide both sides by -4, then by -2

The inequality equation is A

The value of A is -8 < 8

Dividing both sides by -4 , we get

2 > -2

The sign of the inequality relation changes when multiplying or dividing by a negative number

Now , dividing by -2 on both sides , we get

-1 < 1

So , The sign of the inequality relation changes when multiplying or dividing by a negative number

Therefore , the inequality equation first changes and reverts back to the original relation

Hence , the value of the inequality relations are

a) 5040 < 8820

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
