6 A rectangular room is 2 m longer than it is
wide. Its perimeter is 70 m. If the width of
the room is w m, express its length in terms
of zo. Hence find the width of the room.

Answers

Answer:

W = 16.5 meters

Step-by-step explanation:

let w be the width and then the length is w+2

Perimeter = 70 = 2w + 2(w+2)

70 = 2w + 2w + 4

4w = 66

w = 16.5 meters

Elian and Alberto won tickets at a arcade. When they put their tickets together they had exactly 100. Alberto won 10 tickets less then Elian. Let A be the number of tickets Alberto won and e be the number of tickets Elian won.

Answers

Answer: See explanation

Step-by-step explanation:

Number of tickets Elian won = e

Number of tickets Alberto won = A = e - 10

Therefore, Elian + Alberto ticket = 100

e + (e - 10) = 100

2e - 10 = 100

2e = 100 + 10

2e = 110.

e = 110/2

e = 55

Elina has 55 tickets

Alberto has 55-10 = 45 tickets

Quadrilateral ABCD is similar to quadrilateral A'B'C'D'. Select all statements
that must be true.
there is 4 opinion in the photo

Answers

Answer:

Option 1, 2, and 4 are correct. Option 3 is incorrect.

We can conclude that the ratios →

A'B'/AB = A'C'/AC AD/A'D' = BC/B'C' AB/CD = A'B'/C'D'

are true.

What is similarity of triangles?

Two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.

Given is Quadrilateral ABCD is similar to quadrilateral A'B'C'D'.

If Quadrilateral ABCD is similar to quadrilateral A'B'C'D', then we can say that all the sides and diagonals will be resized by the same scale factor of [K]. So, we can say that -

A'B'/AB = A'C'/AC is true

AD/A'D' = BC/B'C' is true

AB/CD = A'B'/C'D' is true

BD/B'D' = C'D'/CD is false.

Therefore, we can conclude that the ratios →

A'B'/AB = A'C'/AC AD/A'D' = BC/B'C' AB/CD = A'B'/C'D'

are true.

Prompt: Sasha wants to go to the department store this Saturday for the big sale. She has saved $45, received $75 from birthday gift cards, and will receive $125 on Friday from work. Her mother reminds Sasha of the $39 she owes her for the last pair of jeans. Sasha also needs to put $50 in her savings. The sale has $40 jeans at 20 percent off and T-shirts on sale for 3 for $15.99. How many pairs of jeans and T-shirts can Sasha purchase? Show or explain how you got your answer.

Answers

Answer:

Step-by-step explanation:

Given that :

Inflow for Sasha = $(45 + 75 + 125) = $245

Outflow = $(39 + 50) = $89

Amount shasha can spend on sale :

$(245 - 89) =$156

T- shirt sales = 3 for $15.99

Pair of Jeans = (1 - 0.2) = 0.8 * $40 = $32

3 pairs of jeans

12 T-shirts at 3 for $15.99

3 jeans = 3 * $32
