Attached is the solution in detail

A) W is a sub space of V

given that V =R^4 and W= [(x1, x2, x3, 0)|x1 ,x2, x3 E..R]

W is a subspace of V because of the following.

let  (x1, x2, x3, 0), (y1, y2, y3, 0)  ∈  W and a, b  ∈ V

now  

a(x1, x2, x3, 0)+b (y1, y2, y3, 0)= (a x1, a x2, a x3, 0)+(b y1, b y2,b y3, 0)

= (a x1+ b y1 , a x2+ b y2 , a x3+ b y3 ,0+0)=  

(a x1+ b y1 , a x2+ b y2 , a x3+ b y3 ,0+0)

LHS =RHS

∈W

since  (a x1+ b y1 , a x2+ b y2 , a x3+ b y3 ) are all elements of R

W is closed under vector addition and scalar multiplication.

Hence W is a sub space of V.

It means that a stem of 7 and leaf of 4 combine to the value 74

We're interested in scores greater than 90, so we'll be focusing on the stems of 9 and 10 only

Stem9 has 6 leaves while stem10 has 1 leaf. That's 6+1 = 7 leaves total, which means we have 7 scores above 90. If there was a leaf of 0 for stem9, then we'd have to ignore it (since it forms the score 90). But we don't have to worry about that for this case.

by using the unitary method, 11 inches of wire can be bought for 44 cents.

We are given that:

14 inches of wire costs 56 cents.

14 inches = 56 cents

Now, by using the unitary method, we get that:

1 cent = 14 / 56 inches.

1 cent = 1 / 4 inches.

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

44 cents = 1 / 4 inches × 44

44 cents = 11 inches.

The counterexample of the statement "the difference of two numbers is greater than the greater number if the smaller number is greater than twice the additive inverse of the greater number"

"The difference of two numbers less than the greater number," is how the claim is expressed.

Give us x and y, where x is greater than y.

Thus, the statement can be interpreted as follows:

x - y < x

To both sides, add x.

-y < 2x

Replace with: y > -2x

This indicates that only when the smaller number is higher than twice the additive inverse of the larger number is the assertion true.

The smaller number must be bigger than twice the additive inverse of the larger number in order for the statement "the difference of two numbers is greater than the greater number" to be false.

Isaac will buy 2 pints and 1 cup of strawberry puree if he wants to buy exactly three bottles.

Given that:-

Quantity of strawberry puree Isaac needs = 3 quarts

Quantity of strawberry puree Isaac already have = 1.75 quarts

Also,

Strawberry puree is available in bottles of 1 pint and bottles of 1 cup.

We have to find the number of bottles each of pint and cup will Isaac need if he want to buy exactly in 3 bottles.

We know that,

1 pint = 0.5 quarts

1 cup = 0.25 quarts

Quantity of strawberry puree needed to be bought = 3 - 1.75 = 1.25 quarts.

Let the number of bottles of pint be x and,

The number of bottles of cup be y

Then, we can write

0.5x + 0.25y = 1.25  ...(1)

x + y = 3  ... (2)

Solving the linear equations in 2 variable by elimination method, we get

Multiplying (1) by 2, we get,

x + 0.5y = 2.5  ...(3)

(2) - (3)

0.5y = 0.5

y = 1

As, x + y = 1

x = 2.

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.

Answer:

x = 4.5 and y = 3

Step-by-step explanation:

Area of a rectangle = length x width

= 12 (2x - y)

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

y = x in the slope intercept form

y - 2 = 1(x -2) in the point-slope form of a line

Step-by-step explanation:

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.

If you want your answer in the slope intercept form

y -2 = 1(x-2)

y - 2 = x - 2  Add two to both sides

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
