What do you mean by inequality?

Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilised to compare the numbers, whether it is less than or higher than.

Inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions.

It is given that Alex has $600 in her checking account and She wants to have at least $250 left in her checking account after buying the computer.

Let the amount of computer be t

According to the question , inequality become:

600 - t ≥ 250

600 - 250 ≥ t

350 ≥ t

Therefore, amount of computer can be 350 or more than 350.

Answer: $50.25

Step-by-step explanation:

     First, we will write an equation to represent this situation.

C = $2.75 + $5D

     Next, we will substitute 9.5 miles into D and solve.

C = $2.75 + $5D

C = $2.75 + $5(9.5)

C = $50.25

Answer:

(a) c = 2.75 + 5d

(b) $50.25

Step-by-step explanation:

(a)

The information tells us the following:

Cost of a taxi ride = $2.75 + (5 * number of miles travelled)

We can use the variables c and d to represent the descriptions:

c = 2.75 + 5d

(b)

Substitute 9.5 into the equation as d:

c = 2.75 + 5(9.5)

Simplify:

c = 2.75 + 47.5

c = 50.25

Therefore, the cost of a 9.5 mile ride is $50.25.

The length of the two arcs and the area of the two circular sectors can be calculated as follows:

Since the semicircle is divided into two circular sectors, each sector has an angle of 180/2 = 90 degrees. Therefore, the smaller circular sector has an angle of 90 * (4/5) = 72 degrees, and the larger circular sector has an angle of 90 - 72 = 18 degrees.

The length of the arc of a circle is equal to the circumference of the circle multiplied by the ratio of the central angle of the arc to 360 degrees. Therefore, the length of the smaller arc is 18 * pi * (72/360) = 8pi cm, and the length of the larger arc is 18 * pi * (18/360) = 2pi cm.

The area of a circular sector is equal to the area of the circle multiplied by the ratio of the central angle of the sector to 360 degrees. Therefore, the area of the smaller circular sector is 18^2 * pi * (72/360) = 288pi cm^2, and the area of the larger circular sector is 18^2 * pi * (18/360) = 72pi cm^2.

Therefore, the length of the two arcs is 8pi cm and 2pi cm, and the area of the two circular sectors is 288pi cm^2 and 72pi cm^2.

The line AC from the diagrammatic expression of the tangent of the circle shows that line AC is 24.0

A tangent of a circle is a line that intersects the circle at a single point. The site at which the tangent intersects the circle is referred to as the site of tangency.

From the given information:

Line |CD| =  Diameter

Line |EA| = radius = 18

Line |DB| = 12

Then, we can infer that line EA = DE since they are both (radii of the circle.)

Line |DE| = |EA| = 18

By using the formula for Pythagoras' theorem, we can find line |EA|.

hyp² = opp² + adj²

where;

Line |BE| = hypotenuse = DB + BE = 12 + 18 = 30

Line |AB| = opposite (x) = ???

Line |EA| = adjacent = 18

Thus;

30² = x² + 18²

900 = x² + 324

-x²  = -900 + 324

Answer: To find out how long it takes the paddle wheel to complete 100 full revolutions, we need to calculate the circumference of the paddle wheel and divide that by the speed at which the fins along the outer edge are traveling.

The formula for the circumference of a circle is:

C = 2πr

where C is the circumference and r is the radius of the circle.

The radius of the paddle wheel is 2 feet (the diameter of 4 feet divided by 2), so the circumference is:

C = 2π * 2 = 8π feet

To find out how long it takes the paddle wheel to complete 100 full revolutions, we divide the number of feet traveled in one revolution (the circumference of 8π feet) by the speed at which the fins are traveling (1.3 feet per second):

100 * 8π feet / 1.3 feet per second = 615.38 seconds

Rounded to the nearest second, it takes approximately 615 seconds for the paddle wheel to complete 100 full revolutions.

This equation only has 1 solution

The distance between the point and the line is 3 units.

Find the equation for line L

Begin by finding the slope of the line through the given points, (4,-1) and (4,9) ; its intercept:

m = (y₂ - y₁) / (x₂ - x₁)

= (9 - (-1) ) / 4 - 4

= 10 / 0

= Undefined

Because the slope is undefined, then line L is a vertical line which has an x-intercept of (4,0):

x=4

Because, line L is vertical, then the line w perpendicular to it is a horizontal line that passes through (1,6)(1,6) so its equation is y=6. Hence, L and w intersect at (4,6) which we will denote as Q.

The perpendicular distance is the distance from point P(1,6) to point Q(4,6) which is simply the absolute value of the difference of the x-coordinates:

d = | 1 - 4 |

= |-3|

= 3

Hence, The distance between the point and the line is 3 units.

Under the same translation as X and X' the coordinates of Y' = (-2, -4) and Z' = (-4, -1)

What is translation of a point in coordinate system?

A translation is a transformation that occurs when a figure is moved from one location to another location without changing its size, shape or orientation. In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved.

According to the given question:

It is given about the points X (-4, -2) and X' (-6, -5).

We see that the translation is moving -2 units horizontally to the left and -3 units vertically down.

Therefore, the point Y(0,0)  is translated to Y'(0-2,-1-3) = Y'(-2,-4)

and the point Z(-2,2)   is translated to Z'(-2-2,2-3)  = Y'(-4,-1).
