Answer 1

value of x is greater than or equal to half.

What is inequality?

A mathematical expression shows the unequal comparison between two or more terms.

Inequalities can be greater than, less than, greater than or equal and less than or equal.

What is the expression of the above inequality?

The difference of x and one third is greater than or equal to one third of x.

The statement can be written as x -1/3 ≥ x1/3

                                                 x -1/3 ≥ x/3

                              x - x/3 - 1/3 ≥ x/3- x/3 [ subtract x/3 from both parts]

                         2x/3 - 1/3 ≥ 0

             now add 1/3 on both parts

        we get, 2x/3 -1/3 + 1/3 ≥1/3

                      2x/3 ≥ 1/3

                   2x ≥ 1

The correct question is attached.

Alex is applying for positions at two different electronic stores in neighboring towns. The first job offer is a $200 weekly salary plus 5% commission on sales. The second job offer is a $75 weekly salary plus 10% commission.

Answers

The  amount of sales at which Company A's offer is the same as Company B's is  $600

How to calculate the amount?

The given parameters that will help us to understand the question are

Company A:

Base = $200

Commission = 10% of sales = .1*S

A = .1S + 200

Company B:

Base = 400

Commission = .05*S

B = .05S + 400

We're looking for the point where they're equal.

200 + .1S = 400 + .05S

Multiply by 100 to get rid of decimals

20000 + 10S = 40000 + 5S

Subtract 20000 from both sides

10S = 20000 + 5S

Subtract 5S from both sides

5S = 20000

Divide both sides by 5

S = 4000

So, at $4000 sales, the two jobs pay the same.

You have to always check your work. This can be done by plugging the values into the basic equations and determining if they check. Or we can graph the two lines and see where they cross.

Company A:

200 + .1(4000) = 200 + 400 = 600

Company B:

400 + .05(4000) = 400 + 200 = 600

Answers

If a number is completely divisible by another number then the quotient will be a whole number and the remainder will be zero.

As the name suggests, divisibility tests or division rules in Maths help one to check whether a number is divisible by another number without the actual method of division.

Finding the product of two or more corresponding integers is done mathematically through the action of multiplication. It is frequently represented by the letters "x" or "*." In order to discover the result of multiplication, a multiplicand, also known as the multiplicand, is multiplied by a multiplier, also known as the multiplier. The result of the two integers, for instance, is 56 if the multiplicand and multiplier are both 8. A multiplication process always yields a greater number as the outcome than either of the initial factors. Multiply is also used to describe the process of adding a number to itself a certain number of times, as in "7 multiplied by 3 equals 21."

How to solve?

For instance, if the multiplication error is 8 x 7 = 56, then the matching division error  56/8 = 7, demonstrating that the result of the division is the other component that was used in the multiplication.

This connection is true for every multiplication and division problem as long as the numbers are utilised consistently in both operations.

What is Equivalent ?

Equal is not the same as equivalent. While comparable indicates similar but not the same, equal means the same in all respects. For instance, 1 + 1 is comparable to 2, even if 2 is supposed to be equal to 2.

Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value for the variable, two algebraic expressions that are equivalent have the same value.

The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since 2/4 and 3/6 both equal the 1/2, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.

The SSS similarity theorem states that if three corresponding sides of two triangles are proportional, then the two triangles are similar. This applies to all triangles, regardless of their size or shape.

To use the SSS similarity theorem, you must know the length of at least three corresponding sides of the two triangles. Once you have this information, you can use the theorem to determine if the two triangles are similar.

It's important to note that to use the SSS similarity theorem, you must know the length of at least three corresponding sides of the two triangles. Without this information, it's not possible to determine if the two triangles are similar.

The sum of two numbers is 10 and the difference of those two

Answers

f + s = 10

| f - s | = 18

-------

This means that:

f = 10 - s

And also that:

| f - s | = 18

(f-s)²=18²

f²- 2sf + s² = 324

But f=10-s

So...

(10-s)² - 2s(10-s) + s² = 324

(10-s)(10-s) - 20s + 2s² + s² = 324

100 - 20s + s² - 20s + 2s² + s² = 324

4s² - 40s + 100 = 324

4s² - 40s + 100 - 324 = 0

4s² - 40s - 224 = 0

1/4 * (4s² - 40s - 224) = 1/4 * 0

s² - 10s - 56 = 0

(s-14)(s+4)=0

So s can be either 14 or -4.

When s = 14, f = -4.

When s = -4, f = 14.

An equation in standard form with an x-intercept of 5 and a y-intercept of -4 is,

⇒ 5x + 4y = 20

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The x - intercept = 4 ,

So, ( 4,0) is a point on the line.

And, The y - intercept = 5,

So, ( 0, 5) is a point on the line.

Now, Slope of the line passing through the point (4, 0) and (0, 5) is,

⇒ m = (5 - 0) / (0 - 4)

⇒ m = - 5/4

So, The slope intercept form of an equation is,

⇒ y  = mx + b

Where, m = slope and b = y- intercept.

Hence, We get;

⇒ y = - 5/4x + 5

We know that;

An equation in standard form is,

⇒ Ax + By = C

So, We get;

⇒ y = - 5/4x + 5

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope.

In the coordinate plane, it describes the slope of the line.

Finding the slope between two separate points and calculating the slope of a line are related tasks.

In general, we require the values of any two separate coordinates on a line in order to determine its slope.

According to our question-

Parallel lines have equal slopes.

Therefore,

m₁ = m₂

The equation for one ship's trajectory is

y = - 13x + 4

utilizing the slope-intercept model

y = mx + b

m = -13

slope = -13

The second vessel sails by the points (3, 5). The second argument could be

5 + 39 = b

b = 44

Angle B= 27, a=28ft, b=18ft solve for measurement(s) of angle c

Answers

Answer: In a triangle, the sum of the angles is 180 degrees. Therefore, if we know two of the angles, we can use this property to find the measure of the third angle.

In this case, we are given angle B = 27 degrees and we want to find the measure of angle C. We can use the following equation to find angle C:

Angle B + Angle C + Angle A = 180

27 + Angle C + 90 = 180

Angle C = 180 - 27 - 90

Angle C = 63 degrees

Additionally, we can use the Law of Cosines to find the measure of angle C.

c² = a² + b² - 2ab * cos(C)

c² = 28² + 18² - 2 * 28 * 18 * cos(C)

c² = 784 + 324 - 1008 * cos(C)

c = √(1108 - 1008*cos(C))

We know that cos(C) = (a² + b² - c²) / 2ab

cos(C) = (784 + 324 - c²) / (22818)

We can substitute the value of c² that we obtained from the first equation and find cos(C) and thus angle C.

So the measure of angle C is 63 degrees.

Is it possible to construct a triangle whose sides are 3.5 cm 9.2 cm and 5.3 cm Why or why not?

Answers

The triangle can be constructed from sides of triangle measuring 3.5 cm 9.2 cm and 5.3 cm due to side rule of triangle.

The possibility to construct the triangle will be found out through the sum of any two sides of triangle. If the sum is greater than the remaining side of the triangle, the construction is possible. Let us assume the side a, b and c of triangle to be 3.5, 9.2 and 5.3 cm.

Now, using the side-side-side rule of triangle -

What is quotient formula?

Answers

A quotient is a number created when two numbers are divided. The formula for this is Quotient = Dividend ÷ Divisor.

The division is the process of dividing one number by any other number to produce a different number. Consequently, the dividend is the number that is divided in this instance. A number's divisor is the one that divides the given number. The quotient is the number that we get as a result.

Then, the quotient formula is given by Quotient = Dividend ÷ Divisor. For example, 50÷5=10. Here, 50 is the dividend, 5 is the divisor, 10 is the quotient, and 0 is the remainder.

What is an equation?

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Given that:

Shirts By Sam

The cost of 10 shirts is $127.5

The cost of 15 shirts is $168.75.

Assume the equation that represents total cost is y = ax+b

Putting x= 10 and y=127.5 in y = ax+b:

127.5 = 10a+b.....(i)

Putting x= 15 and y=168.75 in y = ax+b:

168.75 = 15a+b.....(ii)

Use elimination method to solve equation (i) and (ii).

Subtract equation (i) from (ii)

15a+b = 168.75

10a+b = 127.5

____________

5a = 41.25

a = 8.25

Putting a=8.25 in equation (i)

127.5 = 10×8.25+b

b = 40

The equation is y = 8.25x+40.

Might T Shirt

The cost of 8 shirts is $137

The cost of 12 shirts is $163

Assume the equation that represents total cost is y = ax+b

Putting x= 8 and y=137 in y = ax+b:

137 = 8a+b.....(iii)

Putting x= 12 and y=163 in y = ax+b:

163 = 12a+b.....(iv)

Use elimination method to solve equations (iii) and (iv).

Subtract equation (iv) from (iii)

 8a+b = 137

12a+b = 163

____________

4a = 26

a = 6.5

Putting a=6.5 in equation (iii)

137= 8×6.5+b

b = 85

The equation is y =6.5x+85.

The solution of the system of equations:

y = 8.25x+40 .....(vi)

y =6.5x+85   ......(vii)

Use substitution method to solve equations (vi) and (vii).

Subtract equations:

8.25x+40 - 6.5x-85=0

1.75x - 45 =0

x = 45/1.75

x = 25.71

Putting x = 26 in equations (vi) and (vii)

y = 8.25×26+40 = 254.5

y = 6.5×26+85 = 254

Putting x = 24 in equations (vi) and (vii)

y = 8.25×24+40 = 238

y = 6.5×24+85 = 241

Thus if you buy more than 25 shirts, then prefer Might T Shirt shop.

if you buy fewer than 25 shirts, then prefer  Shirts By Sam.
