Answer:

After the sixth week, she would have more than enough money to buy the racket.

Step-by-step explanation:

First Week

Sarah = 40 + 10 = 50

Owner = 120 - 5 = 115

Second Week

Sarah = 50 + 10 = 60

Owner = 115 - 5 = 110

Third Week

Sarah = 60 + 10 = 70

Owner = 110 - 5 = 105

Fourth Week

Sarah = 70 + 10 = 80

Owner = 105- 5 = 100

Fifth Week

Sarah = 80 + 10 = 90

Owner = 100 - 5 = 95

Sixth Week

Sarah = 90 + 10 = 100

Owner = 95 - 5 = 90

After the sixth week, she would have more than enough money to buy the racket.

How many weeks until Sara has enough money to buy the racket?

40 + 10x = 120 - 5x

10x + 5x = 120 - 40

15x = 80

The diagonal of a quadrilateral
oksian1 [2.3K]

Answer:

Step-by-step explanation:

Quadrilateral is divided into two triangles

Triangle 1:

Diagonal = 16m , h = 12m

Area1 = \frac{1}{2}base *height

         =\frac{1}{2}*16*12\\\\=8*12\\\\= 96 m^{2}

Triangle 2:

Area2 = \frac{1}{2}*16*4

           = 8 * 4

           = 32 square meter

Area of quadrilateral = 96 + 32 = 128 sq.m

Mrs. Lopez is designing her garden in the shape of a rectangle. The area of her garden is 2 times greater than the area of the r
scoray [572]

To find the expression for the area of the rectangular garden we will find the area of the rectangle in the picture and then double it.

Area of the garden will be represented by the expression 32s⁵ ft².

Mrs. Lopez is designing her rectangular garden which is 2 times greater than the area of the rectangle shown in the picture.

Dimensions of the rectangle in the picture are 4s³t ft and 8s² ft.

Therefore, area of the rectangle in the picture = Length × Width

                                                                              = 4s³t × 8s²

                                                                              = 32s⁵t ft²

Since, area of the garden is 2 times greater than the area of the rectangle given in the picture.

Therefore, area of the garden = 2(area of the rectangle given in the garden)

                                                  = 2(32s⁵t) square feet.

                                                  = 64s⁵t square feet

A/ab-bsquare + b/ab-asquare?​
lord [1]

Answer:

\dfrac{(a+b)}{ab}

Step-by-step explanation:

The given expression is :

\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}

It can be solved as follows :

\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}=\dfrac{a}{b(a-b)}+\dfrac{b}{a(b-a)}\\\\=\dfrac{a}{b(a-b)}+\dfrac{b}{-a(-b+a)}\\\\=\dfrac{1}{a-b}(\dfrac{a}{b}-\dfrac{b}{a})\\\\=\dfrac{a^2-b^2}{ab(a-b)}\\\\=\dfrac{(a-b)(a+b)}{ab(a-b)}\\\\=\dfrac{(a+b)}{ab}

So, the solution of the given expression is equal to \dfrac{(a+b)}{ab}.
