You are searching online for the best price you can find for a hat that you really want to buy. The hat originally costs $20 at al three stores. Place the discounts in order of the best buy (at the top) to the worst buy (at the bottom). 1/5 off the price of the hat. 30% off the price of the hat. 5.00 off the hat
Answer:
Best to worst: 30% off, $5 off, 1/5 off. Need an explanation? See below for fully worked out answer!
Step-by-step explanation:
1/5 off of the hat:
1/5 of 20
20 divided by 5 equals 4
$4 would be taken off with this discount. 20-4=16. Therefore the hat would cost $16 at this store.
30% off of the hat:
20 times 30% = 20 times 0.30
20 times 0.30=6.
$6 dollars would be taken off of the hat. 20-6=14. Therefore, the hat at this store would cost $14.
$5 off of the hat.
20-5=15
The hat would cost $15 at this store.
Best to worst: 30% off, $5 off, 1/5 off.

There is a line that includes the point (2, 10) and has a slope of 1. What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Submit
Answer:
The line is y=1x+8
Step-by-step explanation:
We can use point-slope form of a line to make an equation. Point-slope form is as follows:
y-y₁=m(x-x₁)
**The variables y₁ and x₁ are where we will plug in our given coordinates and the variable m is your slope.
1. Plug in the given info:
y-10=1(x-2)
2. Distribute the 1:
y-10=1x-2
3. Add 10 to both sides:
y=1x+8

3n^3+ 4n^2 – 9 and -2n^3 + 4n – 9
The difference between 3n³ + 4n² - 9 and -2n³ + 4n - 9 is 5n³ + 4n² - 4n
Given,
The two expressions are:
a = 3n³ + 4n² - 9
b = -2n³ + 4n - 9
We have to find a - b:
That is,
(3n³ + 4n² - 9) - ( -2n³ + 4n - 9)
Open the bracket and multiply (-) with the terms.
That is,
3n³ + 4n² - 9 + 2n³ - 4n + 9
Now solve the expression:
We get,
3n³ + 4n² + 2n³ - 4n
Add 3n³ and 2n²
Then,
5n³ + 4n² -4n
Therefore, the difference between 3n³ + 4n² - 9 and -2n³ + 4n - 9 is 5n³ + 4n² - 4n

Joe's salary in 2001 was $32,600. In 2002, he received a raise of $1560. Assume he receives the same raise every year. Which function describes Joe's salary after 2001? What is Joe's salary in 2007?
Answer:
function i dont know im looking for the same answer but im pretty sure his salary is going to be 41,960 if you multiply the raise by 6 and 43,520 if you multiply the salary by 7
Step-by-step explanation:
The required Joe's salary will be represented by y = 32600 + 1560(x - 2001) and his salary in the year will be $41,960.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let Joe's salary after x years be y,
According to the question,
y = 32600 + 1560(x - 2001)
Now,
For year x = 2007
Joes income,
y = 32600 + 1560(2007 - 2001)
y = 32600 + 1560(6)
y = $41,960
Thus, the required Joe's salary will be represented by y = 32600 + 1560(x - 2001) and his salary in the year will be $41,960.

Write a system of linear equations for the problem and solve the system using an augmented matrix and your calculator.
Mike works a total of 59hr per week at his two jobs. He makes $8 per hour at job A and $9 per hour at job B. If his total pay for one week is $494 before taxes, then how many hours does he work at each job?
Answer: he works 37 hours in job A, and 22 hours in job B.
Step-by-step explanation:
Let's define the variables:
A = number of hours that he works at Job A
B = number of hours that he works at Job B.
We know that he works a total of 59hr per week, then we have:
A + B = 59
And we also know that he makes $494 in one week, then we have the equation:
A*$8 + B*$9 = $494.
Then we have the system of equations:
A + B = 59
A*$8 + B*$9 = $494
To solve this with an augmented matrix, we need to turn these equations into a matrix, where we only write the coefficients as follows:
[tex]\left[\begin{array}{cccc}1&1&I&59\\8&9&I&494\end{array}\right][/tex]
(The I's should represent a line for the augmented matrix, that line separates the values of the coefficients to the right value of each equation)
The first column represents the A coefficients, the second column represents the B coefficients.
To solve this, we want to get something of the form:
[tex]\left[\begin{array}{cccc}1&0&I&x\\0&1&I&y\end{array}\right][/tex]
Where x and y are our solutions.
To do it we can just do: Column 2 - 8*column 1, this will get us to:
[tex]\left[\begin{array}{cccc}1&1&I&59\\8 - 8*1&9 - 8*1&I&494 - 8*59\end{array}\right][/tex]
=
[tex]\left[\begin{array}{cccc}1&1&I&59\\0&1&I&22\end{array}\right][/tex]
Now we can do: Column1 - column2, to get
[tex]\left[\begin{array}{cccc}1 - 0&1 - 1&I&59 - 22\\0&1&I&22\end{array}\right][/tex]
[tex]\left[\begin{array}{cccc}1&0&I&37\\0&1&I&22\end{array}\right][/tex]
Then the solutions are:
1*A =37
1*B = 22
This means that he works 37 hours in job A, and 22 hours in job B.

The radical equation among the following equations will be 7√ x = 14 as it is the only equation that has a radical variable that is √ x.
A radical equation is an equation which has at least one variable to be put on in a radical form.
In this question, we have only one kind of variable which is x. So, we will only analyze that variable only.
Now, we need to find the equation where x is in the radical form.
The radical form can be expressed with square root symbol.
The option with √ x would be only 7√ x = 14.
Therefore, the radical equation among the following equations will be 7√ x = 14 as it is the only equation that has a radical variable that is √ x.

Now, try to form the statements in the mathematical notation and then solve the equations by performing certain mathematical and algebra operations according to need.
In the question statement,
It is given that total number of transactions are 35 in a given month and pay for 2 banks are given to us. we need to calculate the total payout of transactions for both the banks.
Bank A charge $25 monthly fee on a checking the accounts, plus
$ 0.90 for each transaction.
As Charmaine makes 35 transactions.
Total charges of bank A= $25 + (0.9)35
Total charges of bank A= $25+31.5 = $56.5
Also,
Bank B charge $30 monthly fee on a checking the accounts, plus
$ 0.50 for the each transaction.
Total charges of bank B= $30 + (0.5)35
Total charges of bank B= $30+17.5

So, the triangles cannot be proven congruent
Step-by-step explanation:
Congruence Theorems
Two triangles are congruent if their corresponding sides are equal in length, and their corresponding angles are equal in measure.
The triangles shown in the figure have two clear congruent angles as marked in red color. The third angles located at point P is also congruent because they are vertical angles or opposite angles.
Being all three angles of the same measure, it proves both triangles are similar, but not necessarily congruent. The side lengths may be of the same measure, but they could also be proportional.
So, the triangles cannot be proven congruent
