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

Answers

Answer:

C (.35) on edge2021! :)

Step-by-step explanation:

for this problem we use the formula P(X = k) = (n over k)p^k(1-p)^n-k and in this case,

k = 5

n = 6

p = .90

and (n over k), n choose k, is calculated by (n! / k!(n-k)!) or just look up "6 choose 5" and you'll figure out that it's equal to 6.

so you end up with P(X = 5) = 6(.90)^5(1-.90)^6-5 which will give you .35 when put in a calculator.

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.

Answer:B, I think it's B.~If you look closely the only difference between the two polygons is that they are a different size.So when you divide 21 by 18 to see what fraction is being used to demonstrate the polygon I got, 7/6.So I tried dividing 28 by 7/6 and got the answer, 24.But since it's X + 13, I had to see which answer plus 13 would equal 24, and 11 + 13 = 24.~
