Answer:
Compartment plates is the best buy
Step-by-step explanation:
To find unit price, you can just divide the price by the number of plates
Sturdy plates: 3.28÷24= $0.14/plate
No spill plates: 1.79÷10 = $0.18/plate
Compartment plates: 6.00÷50 = $0.12/ plate
Out of all of the prices, $0.12 is the cheapest

9514 1404 393
Answer:
Y = 6.5°
Step-by-step explanation:
We know that tan(x) = cot(90°-x), so we could rewrite the equation as ...
cot(90 -(3Y+32)) = cot(Y+32)
58 -3Y = Y +32

Jada gets a quarters from a change machine at an arcade. She receives 4 quarters for every
dollar bill, d, that she puts into the machine.
What variable is dependent and independent between The number of dollor bills which is d and the number of quarters which is q??
Answer:
The dollar bills d are the independent variable while the number of quarters q are the dependent variable
Step-by-step explanation:
Here, we want to state the variable that is dependent and the one that is independent
from the question, she has to put in dollars to get the quarters
so the number of quarters she gets is dependent on the number of dollars put into the machine
Thus, we can conclude that;
The dollar bills are the independent variable while the number of quarters q are the dependent variable
Independent variables are those who are not dependent on other variables. In contrast, their exists dependent variables whose value depends on some other variable(s)' value(s).
For given case, the number of dollar bills 'd' is independent variable with respect to variable 'q'.
The number of quarters 'q' is dependent variable.
What are independent variables?Independent variables are those who are not dependent on other variables for their evaluation.
What are dependent variables?Those variables whose value is decided by the values of other variables. This shows that the variable in consideration is dependent on other variables for its values, thus called dependent variable.
Which of 'd' or 'q' is dependent and independent?If you see it carefully, you'll see that the quarters received from the change machine is depending on how much dollar bills you're feeding to the machine.
Thus, the value of 'q' is dependent on the value of d.
But since d takes its value independent of q (it exists before q exists and doesn't need q to get its values), thus, d is not dependent on q or is independent variable with respect to q(i said "with respect to q" since d might be dependent on some other variable which we do not know right know)
Thus:
The variable 'q' is dependent variable (depends on d)
The variable 'd' is independent variable with respect to 'q.

The perimeter of a triangular garden is 72 feet. Find the length of the three sides if the middle length side is 4 feet greater than twice the length of the smallest side, and the longest side is 4 feet less than 3 times the length of the smallest side
Answer:
Smallest length side = 12 ft
Middle length side = 28 ft
Longest length side = 32 ft
Step-by-step explanation:
Perimeter of ∆ = sum of all its length sides
Thus, we are given that:
Perimeter = 72 ft
Let x represent the smallest length side. Therefore:
Smallest length side = x ft
Middle length side = (2x + 4) ft
Longest length side = (3x - 4) ft
Thus:
(2x + 4) + (3x - 4) + x = 72
Solve for x
2x + 4 + 3x - 4 + x = 72
Collect like terms
2x + 3x + x + 4 - 4 = 72
6x = 72
Divide both sides by 6
x = 72/6
x = 12
Find the length of all 3 sides by plugging in the value of x in each expression:
Smallest length side = x ft = 12 ft
Middle length side = (2x + 4) ft = (2(12) + 4) = 24 + 4 = 28 ft
Longest length side = (3x - 4) ft = (3(12) - 4) = (36 - 4) = 32 ft

Part 1:
Graph the following system of equations. What is the solution set?
2x + y = 3
x = 2y - 1
Part 2:
Solve the following system of equations by substitution. What is the solution set?
y = -2x + 3
x - 2y = - 1
Part 3:
Compare the systems of equations and their solutions in Parts 1 and 2. How are they similar? How are they different?
Complete your work in the space provided or upload a file that can display math symbols if your work requires it. Include the graph of the linear system of equations and the process followed in order to solve the system by substitution.
Answer:
Part 1:
The solution set of the system of equations is x = 1, y = 1
Part 2:
The solution set is x = 1, y = 1
Part 3:
The similarity of the system of equations in Parts 1 and 2 is that they have the same solution set
The difference of the system of equations in Parts 1 and 2 is that they are arranged differently
Step-by-step explanation:
Part 1:
The system of equation is given as follows;
2·x + y = 3...(1)
x = 2·y - 1...(2)
The above system of equations can be written in terms of the variable, y, as follows;
For equation (1), we have;
y = 3 - 2·x
For equation (2), we have;
y = (x + 1)/2
From the attached graph created with Microsoft Excel, we have;
The solution set (the point of intersection) of the system of equations is x = 1, y = 1
To accurately find the common solution, we have;
(x + 1)/2 = 3 - 2·x
x + 1 = 2·(3 - 2·x) = 6 - 4·x
x + 1 = 6 - 4·x
x + 4·x = 6 - 1
5·x = 5
x = 5/5 = 1
x = 1
Therefore, y = 3 - 2·x = 3 - 2× 1 = 1, at the common solution
Part 2:
y = -2x + 3
x - 2y = -1
∴ x = 2y -1
y = -2(2y -1) + 3
y = -4y + 2 + 3
5y = 5
y = 1
x = 2y - 1 = 2 - 1 = 1
x = 1
The solution set is x = 1, y = 1
Part 3
The system of equations are similar in terms of their solution
The system of equations are different in terms of their arrangement

James completely covered a square poster board using 68.2 inches with an exponent of 2.of cardstock. Which measurement is
closest to one side of the poster board in inches?
A) 34 in.
B) 8 in.
C) 6 in.
D) 30 in.
Answer:
A. 34in
Step-by-step explanation:
If James completely covered a square poster board using 68.2 inches with an exponent of 2, the the total perimeter of the square will be;
P = 2(68.2) = 136.4in
Since the perimeter of a square is expressed as:
P = 4L
136.4 = 4L
L = 136.4/4
L = 34.1in
Hence the measurement of one side of the square poster is closest to 34in

For one type of car tire, the tire pressure in pounds per square inch (psi) is assumed to be approximately Normal with a mean of 35 psi and a standard deviation of 2 psi. A tire is labeled as underinflated if its pressure is 32 psi or below. What percentage of tires are underinflated?
a. 2.28%
b. 6.68%
c. 93.32%
d. 97.72%
Answer:
B 6.68
Step-by-step explanation:
The solution is, 30.854% is the percentage of tires are underinflated.
What is Z-score?In statistics, the standard score is the number of standard deviations by which the value of a raw score is above or below the mean value of what is being observed or measured. Raw scores above the mean have positive standard scores, while those below the mean have negative standard scores.
here, we have,
First, we find the z-score corresponding to the value given
z-score = (x - mean)/SD
Z-score = (36-35)/2 = 1/2 = 0.5
we find the Probability of (x > 0.5)
we use the standard normal distribution table for this
P( x > 0.5) = 0.30854
This has a percentage 30.854%.

f(x)=x²+4x-7 determine the vertex
Answer:
The vertex of this parabola is [tex](-2,-11)[/tex]
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation [tex]-\frac{b}{2a}[/tex]
From the function [tex]f(x)=x^2+4x-7[/tex], we can see that
[tex]a=1\\b=4\\c=-7[/tex]
This means that
[tex]-\frac{b}{2a}=-\frac{4}{2(1)} =-2[/tex]
So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.
[tex]f(x)=x^2+4x-7\\\\f(-2)=(-2)^2+4(-2)-7\\\\f(-2)= 4-8-7\\\\f(-2)=-11[/tex]
Thus, the vertex of this parabola is [tex](-2,-11)[/tex]

what is mean mode and median
Answer:
mean is the average of the numbers (add them all up then divided by how many number there are)
mode is the number that comes out the most often
range is the largest number minus the smallest
median is the middle number when they are lined up from greatest to the least (unless there's two)
Step-by-step explanation:
a song we learned in 5th grade XD that i still remember somehow
Answer:
This is what mean, median, and mode are-
Step-by-step explanation:
Mean is when you add all the number there are and divide by the total of numbers that you added together like this for example.
(1+2+3+4+5 = 15) THEN (15 / 5 = 3) THE MEAN IS 3.
Median is when you group the number from smallest to biggest and keep on crossing out both side of the number till you reach the middle.
(1, 2, 3, 4, 5) YOUR MEDIAN SHOULD BE 3 CAUSE IF YOU CROSS OUT 1,5 THEN 2,4 YOU WILL GET 3.
Mode are the most common number that you will see. You could have no mode or many mode too.
(1, 2, 2, 3, 4, 5) THERE IS ONLY ONE MODE HERE WHICH IS 2.
(1, 2, 3, 4, 5) THERE IS NO MODE CAUSE THERE IS NO REPEATING NUMBER.
(1, 2, 3, 4, 4, 5, 5) THERE IS TWO MODE NOW WHICH ARE 4 AND 5.
