Mayonnaise cost of £4.75 for a 2 liter jar lowest price Eleanor can buy.

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

How to Apply the Unitary Method

Let's first list the data that we currently have. The number of ice creams is 5. It costs $125 for 5 ice creams.

step 1:Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.

Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.

Given:

Cots of 1 liter jar of Mayonnaise (I) = 2.45

Cost of 2 liter jar of Mayonnaise (II)=4.75

Cots of 1 liter jar of Mayonnaise (II)= 4.75/2= 2.375

If she eats half liter Mayonnaise in a day

So, she eat in 14 days = 0.5 x 14 = 7 liter

Hence, Mayonnaise cost of £4.75 for a 2 liter jar lowest price Eleanor can buy.

To determine whether the third figure is a translation image of the first figure, we say that; B: No; it is a reflection followed by a translation

Transformation could be reflection, translation, rotation or even dilation.

Reflection can be thought of as the mirror image of a shape across a line.

Rotation is when one turns an object around a point

Translation is simply moving an object from one point to another without any change of dimension.

If we look at the given three figures in the attached image, we can see that the second image is the reflection or mirror image of the first figure.

After reflection, we can see that it is undergoes translation, which means it is moved apart from the first figure.

Thus, the third figure is a reflection of the first figure, and then it is translated.

Its A, A is congruent to B and B is congrument to c

The translation equation, often known as the vertical translation equation, is g(x) = f(x+k) + C.Because the triangles are not congruent, Figure B is not an exact replica of Figure A.

In what direction does a figure move on a coordinate grid?

An example of one of these is a translation. A geometric figure moves in the coordinate plane when it slides up, down, left, or right. The figure shifts its position but maintains its original orientation. Additionally, it maintains its size and shape.

The vertical translation equation, or the formula for translation, is g(x) = f(x+k) + C.

The volume of prism A and B are 27 cm³ and 25 cm³ respectively and the Surface area of prism A and B are 54 cm² and 70 cm² respectively.

No, the prism with a greater volume doesn't always have the greatest surface area.

Given:

Prism B is a rectangular prism, whereas prism A is a cube.

The prism's volume is determined by

Volume = length × width × height

So, the Volume of prism A whose each side 3 cm is,

Volume of prism A = 3 × 3 × 3 = 27 cm³

Volume of prism B with sides 5 cm,5 cm, and 1 cm is

Volume of prism B = 5 × 5 × 1 = 25 cm³

The cube's surface area is 6a², where a is one of the cube's sides. So

Surface Area of prism A = 6 × (3)² = 6 × 9 = 54 cm²

Surface area of the rectangular prism is given by,

2(length × width + length × height + width × height)

Surface Area of prism B =  2(5×5 + 5×1 + 5×1)

                                        = 2(25 + 5 + 5)

                                        = 2 × 35 = 70 cm²

From the above calculations, it is clear that the prism with a greater volume doesn't always have the greatest surface area.

Step-by-step explanation:

The bottom two expressions are polynomials.

The loan that was borrowed by Georgina was for a period of 9 years.

From the information, Gregoria borrowed $2,450, to be paid back at 3.5% annual simple interest. She repays $3,221.75. The Interest will be:

= $3,221.75 - $2,450

= $771.75

Therefore, the time taken for the loan will be expressed as:

Interest = PRT/100

where P = Principal

R = Rate

T = Time.

Interest = PRT/100

771.75 = (2450 × 3.5 × T) /100

Cross multiply

8575T = 77175

Time = 77175 / 8575

Time = 9

The time is 9 years.

Based on the definition of the functions, the value of x if f(x) = g(x) is 3

The equations of the functions are given as

f(x) = -2x + 4

g(x) = 2x - 8

It should be noted that the above equations are linear equations

From the question, we understand that the functions are equal

This means that, we have the following equation

f(x) = g(x)

Substitute the known values in the above equation

So, we have the following equation

-2x + 4 = 2x - 8

Collect the like terms in the above equation

So, we have

2x + 2x = 8 + 4

Evaluate the like terms in the above equation

So, we have

4x = 12

Divide both sides by 4

x = 3

Hence, the value of x such that the equations are equal is 3

Triangle B is not a rotation of triangle A because on careful observation of this two triangles, one would see that they are mirror images of each other; reflections of each other.

A mental rotation of triangle A all through the 360° shows that at no point is it seeming exactly like triangle B.

This is why it is evident that triangle B is not a rotation of triangle A, rather, they are reflections of each other.

Answer:

<U = 54

<T = 72

Step-by-step explanation:

Find the angle measures

The marks on the sides means the sides are the same length

That means the base angles have the same measurement

<S = <U = 54

The sum of the angles of a triangle equals 180

<S + <U + < T = 180

54 + 54 + < T =180

108 + < T =180

<T =180-108

<T = 72

Answer:

m<U = 54°

m<T = 72°

Step-by-step explanation:

According to the isosceles triangle theorem ( If two sides of a triangle are equal , then the angles opposite to these sides are also equal. ),

ST = UT

So,

m<S = m<U.

Given that,

m<S = 54°

So,

m<U = 54°

Also, we know that the sum of the interior angles of a triangle is added up to 180 degrees.

So,

m<S + m<U + m<T = 180°

54° + 54° + m<T = 180°

108° + m<T = 180°

m<T = 180° - 108°

m<T = 72°

Step-by-step explanation:

Well whenever any function crosses the x-axis, it means that the y-value is equal to zero.

In this case when the derivative passes the x-axis it indicates the tangent line corresponding to that x-value has a slope of zero, which when plotted is a horizontal line.

This means that the graph f has 3 horizontal tangent lines.
