help me i am helpless.

The inequality that would represent the possible values for the number of hours washing cars, ww, and the number of hours tutoring, tt, that Addison can work in a given week is 5ww + 11tt ≥ 85.

Amount earned by Addison per hour in washing cars = $ 10

Amount earned by Addison per hour in tutoring = $ 22

Minimum amount Addison must earn this week = $ 170

We have to find an inequality  that would represent the possible values for the number of hours washing cars, ww, and the number of hours tutoring, tt, that Addison can work in a given week.

Based to the data given in the question, we can write the inequality,

10ww + 22tt ≥ 170

Dividing the inequality by 2, we get

5ww + 11tt ≥ 85

Answer:

Distance between coordinates is given as √(x1-x2)²+(y1-y2)², where x and y are the coordinates of the points.

Length of ST = √(-2-3)²+(4-9)²

= √(-5)²+(-5)²

= √25+25

= √50

= 7.07

= 7.1 (nearest tenth)

The real square roots of 0.0036 will be A 0.06 and -0.06.

The result of multiplying a number by itself yields its square value, while the square root of a number can be found by looking for a number that, when squared, yields the original value. It follows that a a = b if "a" is the square root of "b."

It should be noted that this is a component of a number that yields the original number when multiplied by itself

The square root will be illustrated as:

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

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.

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.

Answer:

0.5 repeating

Step-by-step explanation:

This is because any fraction with a denominator of 9 is a repeating decimal.

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

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.

In the question,

it is given that ,

the parabola passes through (0,-18) and has x intercepts as 9 and 1 .

The intercept form of the equation of parabola is given by

y = a(x-p)(x-q)   , where a is the constant

and p , q are the x intercepts  .

Given that the parabola has x intercepts as 9 and 1 , So

equation becomes

y = a(x-9)(x-1)          .....(i)

Since parabola passes through the points (0,-18) ,

hence , point should satisfy the equation ,

So putting y = -18 and x=0 , we get

-18 = a(0-9)(0-1)

-18 = a(-9)(-1)

-18 = 9a

a = -2

Substituting a= -2 in equation (i) ,

we get the equation of parabola as y = -2(x-9)(x-1) .

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,
