The inequality that shows the least amount of money she needs to deposit to avoid a fee is 585.43 - 302.05 + x ≥ 300

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

Let x represent the least amount of money Keisha needs to deposit to avoid a fee. Keisha has $585.43 in her checking account and must maintain a balance of $300 to avoid a fee. She wrote a check for $302.05 today, Hence:

585.43 - 302.05 + x ≥ 300

The area hexagon using Lin's and Andre's method is:

By Lin's method = 93.48inch^2

By Andre's method = 93.53 inch^2

What is Mensuration ?

The field of mathematics known as mensuration explores how to measure geometric objects and their attributes, such as length, volume, shape, surface area, lateral surface area, etc.

By Lin's method

He parted the hexagon into six equilateral triangle

So, area of equilateral triangle = √3/4 × (side)^2

Since the given side = 6inch

Therefore,

                area of equilateral triangle = √3/4 × (6)^2

                                                              =√3/4 × 36

                                                              = √3 x 9

                                                              = 1.732 x 9

                                                              = 15.58inch^2

The area of hexagon will be = 15.58 x 6

                                               = 93.48inch^2

Now, By Andre's method

he parted two triangle and one rectangle

The triangle has two equal side that means its an isosceles triangle

Area of isosceles triangle using only sides = ½[√(a^2 - b^2/4) × b]

given,

base = 10.4 inch

side = 6 inch

Area of isosceles triangle using only sides = ½[√(a^2 - b^2/4) × b]  

                                                                       = ½[√(6^2 - 10.4^2/4) × 10.4]

                                                                       = ½[√(36 - 108.16 /4) ×10.4]

                                                                       = ½[√(36 - 27.04) × 10.4]      

                                                                       = ½[√(8.96) × 10.4]

                                                                       = ½[2.99 × 10.4]  

                                                                       = 15.56inch^2

for two triangles the area will be =    15.56 x 2

                                                      = 31.13 inch^2

Now, area of rectangle = length x width

where,

Length = 10.4 inch

Width = 6 inch

So,

     area of rectangle = 10.4 x 6

                                   = 62.4 inch^2

Then, The area of hexagon will be = area of rectangle + area of two triangle

                                                          = 62.4 inch^2 + 31.13 inch^2

                                                          = 93.53 inch^2

Hence, by both methods the area from Lin's method = 93.49 inch^2

and by Andre's method = 93.53 inch^2

The equation for the line that is parallel to the given line and goes through the point (-8 2), is y = 3x + 26. See the explanation below.

Recall that the equation for the line is always given as:

y = mx + b

Where m is the slope.

Assuming that you have a line  y = 3x + 2

The line parallel to this line but intersecting the point (-8,2) is found by using y = mx + b and solving for b

m = 3; x = -8; and y = 2

b = y - mx

b = (2) - (3) (-8)

b = 26

The cost for 1.42 kg of this cheese will be $ 31.44 .

The process of translating measurements of a given quantity between different units, frequently using multiplicative conversion factors that change the value of the measured quantity without changing its effects, is known as unit conversion. The specific circumstances and the desired result dictate the conversion process. This may be governed by a regulation, contract, set of technical requirements, or other publicly available standards.

In its simplest form, the unitary procedure is used to determine the value of a single unit from a given multiple.

How to calculate the value of one pen, for example, if 40 cost Rs. 400. To finish it, using the unitary method. Additionally, after the value of a single unit has been established, we can multiply that value by the quantity of additional units required to establish the value of the additional units. This is typically how the concepts of ratio and proportion are used. The unitary method entails calculating the value of a single unit before calculating the value of the required number of units.

Given that 0.429 kg of cheese cost $9.50

As a result, the price of 1 kg of cheese is $9.50/0.429, which is $ 22.14.

As a result, 1.42 kg of cheese will cost you $22.14 * 1.42 = $31.44.

The recursive formula of the arithmetic sequence is:

xₙ = n*4 + 13

With that we can see that x₁₁ = 57

Here we know that the first elements of the sequence are:

17, 21, 25, 29, ...

To find the common difference, d, we take the difference between any two consecutive elements, so we have:

c = 21 - 17 = 4

Then the recursive formula for the n-th term is:

xₙ = n*4 + d

The first element x₁ is 17, so we will have:

17 = 1*4 + d

17 - 4 = d = 13

The recursive formula is:

xₙ = n*4 + 13

b) the eleventh term of the sequence is given by replacing n in the above formula by 11.

Based on the length of the object in real life, and the scale factor used, the length of the object on the scale drawing in inches can be found to be 9.17 inches

The scale factor tells us how the measurement of an object on a drawing relates the measurement of the same object in reality.

For a scale factor of 1 inch to 6 feet, it means that every inch of an object on a drawing, would be 6 feet of the same object in real life.

For this object that is in a drawing with a scale factor of 1 inch to 6 feet, the length in real life of 55 feet tells us that the length in the drawing is:

= Number of feet in real life / Number of feet in scale factor per drawing

= 55 / 6

Perpendicular slopes are opposite reciprocals of each other.  So the perpendicular slope would be 1.

We could write this in the point slope form of a line and the answer would be:

y - 2 = 1(x -2)  This would be the point slope form of a line.

x = 4.5 and y = 3

Step-by-step explanation:

Area of a rectangle = length x width

Area is given as 72

∴ 12 (2x - y ) = 72

Divide both sides by 12 =>

12/12 (2x - y) = 72/12

2x - y = 6    [1]

The kite perimeter is 33
Your equation is correct:
2(3x) + 2(y) = 33

=> 6x + 2y = 33   [12]

So we have two equations and we can solve them as follows

Multiply [1] by 2
2(2x -y) = 2 x 6

4x - 2y = 12          [3]

Coefficients of y in equations [1] and [2] are same but of opposite sign

Add [1] and [3]

    6x + 2y = 33
+
    4x  - 2y = 12

-------------------------
   10x + 0   = 45

=> 10x = 45

Divide both sides by 10

=> x= 45/10

x = 4.5

Substitute for x in equation [1]: 2x - y = 6

=> 2(4.5) - y = 6

=> 9 - y = 6

Subtract 9 from both sides

9 - 9 - y = 6 - 9

-y = -3

Multiply by -1 both sides
y = 3

Answer: x = 4.5 and y = 3

1 cent = 14 / 56 inches.

1 cent = 1 / 4 inches.

Now, for 44 cents, by using the multiplication, we get that:
