As a member of a dance troupe, Anita has a costume wardrobe that consists of 2 pairs of tights (1 white pair and 1 black pair), 3 T-shirts (1 pink, 1 blue, and 1 green), and 3 scarves (1 silver, 1 gold, and 1 white). If a costume consists of either a pair of tights and a T-shirt with a scarf or a pair of tights and a T-shirt without a scarf, how many different costumes are possible?
Answer:
24
Step-by-step explanation:
24
The total number of different costumes possible is 24 if Anita has a costume wardrobe that consists of 2 pairs of tights, 3 T-shirts, and 3 scarves.
What are permutation and combination?A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Anita has a costume wardrobe that consists of 2 pairs of tights (1 white pair and 1 black pair), 3 T-shirts (1 pink, 1 blue, and 1 green), and 3 scarves (1 silver, 1 gold, and 1 white).
The costume consists of either a pair of tights or a T-shirt with a scarf:
In this case total number of ways = 2×3×3 = 18
Pair of tights and a T-shirt without a scarf:
In this case total number of ways = 2×3 = 6
Total number of different costumes are possible:
= 18 + 6
= 24
Thus, the total number of different costumes possible is 24 if Anita has a costume wardrobe that consists of 2 pairs of tights, 3 T-shirts, and 3 scarves.

Hailey went to Frank's Market and bought 1 3/4 pounds of coffee at $13 a pound and 8 1/2 pounds of rice at $0.45 pero pound. If Hailey paid with a $50 Bill how much chance did she receive?
Answer: She received $18.42 as change.
Step-by-step explanation:
Given: Cost of coffee per pound = $13
[tex]1\dfrac34[/tex] pounds of coffee costs [tex]=1\dfrac34\times 13=\dfrac{4+3}{4}\times 13[/tex]
[tex]=\dfrac74\times 13\\\\=\$ 22.75[/tex]
Cost per pound of rice = $0.45
[tex]8\dfrac12[/tex] pounds of rice costs = [tex]8\dfrac12\times 0.45=\dfrac{17}{2}\times0.45[/tex]
[tex]=\$3.825[/tex]
Bill amount = $ (22.75+8.825) = $ 31.575≈ $31.58
If Hailey paid $50, then she will receive = $(50-31.58)
= $ 18.42
Hence, She received $18.42 as change.
Answer: She received $18.42 as change.
Step-by-step explanation:
Given: Cost of coffee per pound = $13
pounds of coffee costs
Cost per pound of rice = $0.45
pounds of rice costs =
Bill amount = $ (22.75+8.825) = $ 31.575≈ $31.58
If Hailey paid $50, then she will receive = $(50-31.58)

Find the value of x. (2x +4)° 2x-9)°
Answer: x=3
Step-by-step explanation: 2x +4)° 2x-9)°= 4x 2 +8x−9=3
Pull out like factors :
2x + 4 = 2 • (x + 2) (4 • (x + 2) • x) - 9
4x • (x + 2) - 9
Factoring 4x2+8x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 4 • -9 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is 8 .
-36 + 1 = -35
-18 + 2 = -16
-12 + 3 = -9
-9 + 4 = -5
-6 + 6 = 0
-4 + 9 = 5
-3 + 12 = 9
-2 + 18 = 16
-1 + 36 = 35

The value of x for the given triangle is 37°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
The sum of all interior angles of a triangle is 180°.
So,
x + 2x +4 + 2x-9 = 180°
5x - 5 = 180°
x = 37°
Hence "The value of x for the given triangle is 37°".

mom bought a dress for 320 dollars during the big sale its original price is 400 yuan how much is the discount
Answer:
20% discount
Step-by-step explanation:
Given the following question:
20% of 400
To find the answer we will use the formula to calculate percentages, once we have that answer we then subtract it from the original price to see if we have the same new price as the question.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{20\times40}{100}[/tex]
[tex]20\times40=8000[/tex]
[tex]8000\div100=80[/tex]
[tex]=80[/tex]
Subtract from the original price:
[tex]400[/tex]
[tex]400-80=320[/tex]
[tex]=320[/tex]
The dress has a "20% discount."

The solution to the equation takes the form a/2+b, where, a = -4 and b= -3, is 4 or -5 depending on the equation used.
What is the substitution of variables into an equation?The substitution of variables takes a defined pattern. In the given question, we are to replace the following values for a and b. i.e. a = -4 and b = -3 into the equation a/2+b.
So,
If a = - 4;and b = -3Then, using the expression:
[tex]\mathbf{=\dfrac{a}{2+b}}[/tex]
The solution to the equation can be calculated as:
[tex]\mathbf{=\dfrac{-4}{2+(-3)}}[/tex]
[tex]\mathbf{=\dfrac{-4}{-1}}[/tex]
Divide both the numerator and denominator by (-1)
= 4
However, if the equation is [tex]\mathbf{\dfrac{a}{2}+b}[/tex]
The solution to the equation will be as follows:
[tex]\mathbf{\dfrac{-4}{2}+(-3)}[/tex]

On a piece of paper, use a protractor to construct a triangle with angle measures of 60° and 80°. I Which statements about this triangle are true? Select all correct answers.
Answer:
Option A

Step-by-step explanation:
Triangle attached in image~
A) It is an acute triangle (Yes)
Before we put reasonings why this is true, let's find the missing angle in the triangle.
⇒ 60 + 80 + x = 180°⇒ 140 + x = 180°⇒ x = 180 - 140⇒ x = 40°This triangle is an acute triangle because all angles in the triangle are acute, as 80°, 60°, 40° are acute angles.
B) Two sides have the same length (No)
Two sides can only be the same if two angles are equivalent. Since all angles are different, two sides cannot have the same length.
C) All sides have different lengths (Yes)
Since all angles are unalike, the triangle has different side lengths.
D) The third angle measures 40° (Yes)
⇒ 60 + 80 + x = 180°⇒ 140 + x = 180°⇒ x = 180 - 140⇒ x = 40°Answer:
