gio paid $30 to have 6 shirts cleaned at the dry cleaners. What is the constant of proportionality that relates the cost in dollars to clean shirts , y , to the number of shirts, x?
Answer:
The constant of proportionality is 5
Step-by-step explanation:
Given
[tex]y = \$30[/tex] --- Cost
[tex]x = 6[/tex] --- Number of shirts
Required
Determine the constant of proportionality
The relationship between y and x is:
[tex]y =kx[/tex]
Where:
k = constant of proportionality
Substitute [tex]30\ for\ y[/tex] and [tex]6\ for\ x[/tex]
[tex]30 = k * 6[/tex]
[tex]30 = 6k[/tex]
Divide both sides by 6
[tex]\frac{30}{6} = \frac{6k}{6}[/tex]
[tex]\frac{30}{6} = k[/tex]
[tex]5 = k[/tex]
[tex]k = 5[/tex]
The constant of proportionality is 5

Is there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a
congruence statement,
If no, justify your answer.
Step-by-step explanation:
The triangles are congruent due to Hypotenuse-Leg congruence. (HL congruence)
Each of the triangles have a right-angle, a congruent hypotenuse and a congruent side of the triangle.
Therefore Triangles ABC and PRQ are congruent.
Answer:
YesStep-by-step explanation:
Given
Right triangles with congruent hypotenuse and one leg.This is sufficient for HL (Hypotenuse, Leg) congruence theorem

Brad buys a jacket that is on sale for 30% off the original price.The expression p - 0.3p can be used to find the sale price of the jacket, where p is the original price of the jacket. If the original price of the jacket is $80, what is the sale price?
Answer:
$56
Step-by-step explanation:
The jacket is on sales for 30% off the original price = (0.3)
The original price (P) = $80
However, the expression "p - 0.3p" is to be used to find the sales price
The sale price = p - 0.3p
The sale price = $80 - 0.3($80)
The sale price = $80 - $24
The sale price = $56

Answer:
8=w, -8=w (±8=w)
Step-by-step explanation:
192=[tex]3w^{2}[/tex]
First, divide by 3
64=w²
now take the square roots of 64 and w² ( we're thinking about which numbers/variables will be multiplied to get 64 and w². They are 8 and w. But wait! -8 can also work, since when you square it a negative number, it will turn positive. )
8=w, -8=w
You can also write it as ±8=w

Diego scored 9 points less than Andre in the basketball game. Noah scored twice as many points as Diego. If Noah scored 10 points, how many points did Andre score?
Answer:
lets call andere A and diego D.
so
A-9=D
D times 2 = n
now we divide 10/2 and thats 5
diego scored 5 points so we can sub in
A-9=5
now we add 9. making 14
ANDRE SCORED 14
Answer:
Diego scored 14 points
x = 14

Answer:
Domain and Range in set notation
Domain: {x|x=4,0,-2}
Range: {x|x=-1,4,9,-9}
Step-by-step explanation:
We are given a relation G
G={(4,-1),(0,4),(-2,9),(-2,-9)}
We need to find domain and range of the relation G
Domain: The domain is the set of all first elements of ordered pairs (x-coordinates)
Range: The range is the set of all second elements of ordered pairs (y-coordinates).
So for the given relation G={(4,-1),(0,4),(-2,9),(-2,-9)}
Domain is: (4,0,-2)
Range is: (-1,4,9,-9)
So, Now writing Domain and Range in set notation
Domain: {x|x=4,0,-2}
Range: {x|x=-1,4,9,-9}
Kendra bought 163 donuts for $60. Her profit was $55 once she had sold 100 donuts. Which equation below
represents Kendra's profit P(n), as a function of the number sold, n ?
Answer:
Concept: Mathematical Modeling
163 donuts for 60 She mad 55 in profit: 55/163= .33 per donut P(n)= 163(n)Note: You didn't provide the optionsThe equation which represents Kendra's profit P(n) will be P(n) = 0.55n.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
Given,
Profit was $55 by selling 100 donuts
Profit per donuts = 55/100 = $0.55
Let's say she sold n number of donuts
Then.
Profit P(n) = 0.55n.
Hence "Kendra's profit P(n) will be P(n) = 0.55n".

Let the random variable Q represent the number of students who go to a certain teacher's office hour each day. The standard deviation of Q is 2.2. Which of the following is the best interpretation of the standard deviation? А. On average, the number of students going to an office hour varies from the mean by about 2.2 students. B. For a randomly selected office hour, the number of students who will go is 2.2. C. For a randomly selected office hour, the number of students expected to go will vary from the mean by 2.2 students. D. For a random selection of office hours, the average number of students expected to go is 2.2. E. For a random selection of office hours, the E average number of students expected to go will vary from the mean by 2.2 students.
Answer: А. On average, the number of students going to an office hour varies from the mean by about 2.2 students
Step-by-step explanation:
The standard deviation is a measure of spread, which gives how values deviate from the average or mean value of a particular distribution. Hence, the standard deviation is usually defined about the average value of a distribution.
Therefore, for a certain random variable representing the number of student who visits office hours, the standard deviation will be defined about the average or mean value of the random variable Q.
Thus, stated as ; number of students going to an office hour varies from the mean by 2.2 on average.

Answer:
1. b = 47
2. c = 18
Step-by-step explanation:
From the question given above, we can see that the two shapes are right angle triangle.
Thus, if ΔUVW ≅ ΔFED, then
1. VW = ED
2. UW = FD
3. UV = EF
1. Determination of the value of b.
UW = 47
FD = b
UW = FD
47 = b
Therefore,
b = 47
2. Determination of the value of c.
VW = c
ED = 18
VW = ED
c = 18

What is an equation of the line that passes through the points (-3,-1) and
(6,2)? Put your answer in fully reduced form.
Answer:
y=1/3x
When x of the line is -3, y of the line must be -1.When x of the line is 6, y of the line must be 2. y=1/3x+b. b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the two points (-3,-1) and (6,2).(-3,-1). y=mx+b or -1=1/3 × -3+b, or solving for b: b=-1-(1/3)(-3). b=0.b came out to be zero, so there is no "+b" term.
Which point is in the solution set of the given system of inequalities?
Answer:
(1/5, 9/5)
Step-by-step explanation:
Given the set of inequities
x+y>2..... 1
4x-y≥-1 .... 2
We are to get the solution point (x,y)
Solving simultaneously
From 1:
x>2-y
Substitute into 2
4(2-y)-y≥-1
4(2)-4y-y≥-1
8-5y≥-1
-5u ≥-1-8
-5y ≥-9
y≤9/5
Since x>2-y
x>2 - 9/5
x>1/5
Hence the required point is (x,y) = (1/5, 9/5)
