Zack wants to make a profit of more than $300 for painting 4 identical rooms. The profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. Which inequality and solution represent the dollar amount, n, that zack must be paid for each room if he is to make a profit of more than 300$
A: n-4(32.5) > 300;n > 430
B: (n - 32.5) > 1,200; n > 332.5
C. (n-32.5)>300;n> 107.5
D 4n-32.5 > 300; n > 83.125
Answer: A
n-4(32.5) > 300;n > 430tep-by-step explanation:
given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is
Profit > $300
Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is
n - 32.5 and
P + 32.5 × 4
Where 4 = number of rooms
P + 130
The minimum profit = 300 + 130 = $430
Therefore, the inequality and solution that represent the dollar amount, n, that zack must be paid for each room if he is to make a profit of more than 300$ is
n-4(32.5) > 300;n > 430
Final answer:
The correct inequality to represent the amount Zack must be paid per room to make a profit of more than $300 is C: (n-32.5) > 300; n > 107.5. After solving the inequality, it shows that n must be greater than $107.5 per room.
Explanation:
Zack aims to make a profit of more than $300 for painting 4 identical rooms. The cost of supplies per room is $32.50, and Zack's profit is based on what he's paid minus the supplies costs. To find the minimum amount, n, he needs to be paid per room to achieve this profit, we set up an inequality where the total amount paid for all rooms minus the total cost of supplies is greater than the desired profit.
The correct inequality is:
4n - 4(32.5) > 300
When simplified, this inequality becomes:
4n > 300 + 4(32.5)
4n > 300 + 130
Now, we solve for n:
4n > 430
n > 107.5
This means each room must be paid for an amount greater than $107.5 for Zack to make his desired profit. Therefore, the correct answer is C.

what is the solution to the system of equations below?
{2y=x+6
{3x=y+7
Answer:
x=4, y=5
Step-by-step explanation:
2y=x+6
3x=y+7
If you subtract 6 from both sides of the first equation, x will be isolated and you can plug it into the second equation. The new first equation is 2y-6=x, which when plugged into the second equation yields:
3(2y-6)=y+7
6y-18=y+7
5y=25
y=5
x=4
Hope this helps!
Final answer:
To solve the given system of linear equations, we use substitution to express x in terms of y from one equation and substitute it into the other, giving us the solution x = 4, y = 5.
Explanation:
The solution to a system of linear equations can be found by various methods, including substitution or elimination. The given system, which appears to be:
2y = x + 63x = y + 7This can be solved by using these methods. First, we will express one variable in terms of the other from one of the equcations and then substitute this into the second equation. Taking the first equation:
2y = x + 6
we can solve for x:
x = 2y - 6
Now, we substitute x in the second equation:
3(2y - 6) = y + 7
This simplifies to:
6y - 18 = y + 7
Now, let's solve for y by isolating it on one side:
6y - y = 7 + 18
5y = 25
y = 5
With the value of y, we can now substitute back into the equation x = 2y - 6 to find x:
x = 2(5) - 6
x = 10 - 6
x = 4
Therefore, the solution to the system of equations is x = 4, y = 5.

Write an equation in which the quadratic expression 4x^2-26x+42 equals 0. Must show all work to receive credit.
Show the expression in factored form
Explain what your solutions mean for the equation in complete sentences.
HIGH POINT AND BRAIN LIST
Answer:
(a) (x + 3)(2x + 7) = 0
(b) These solutions mean that for these two x values, f(x) is equal to 0. It's also where the graph of f(x) crosses the x-axis.
Step-by-step explanation:
(a) We set 4x² -26x + 42 equal to 0:
4x² -26x + 42 = 0
Let's divide both sides by 2 to simplify this a bit:
2x² - 13x + 21 = 0
Now, we need factors a and b of 2 and c and d of 21 such that ac + bd = -13. The factors of 2 are: 1 and 2, so let's say a = 1 and b = 2. The factors of 21 are: (1, 21), (3, 7), (-1, -21), and (-3, -7). We see that if c = -7 and d = -3, this works:
ac + bd = 1 * (-7) + 2 * (-3) = -7 - 6 = -13
So, the factored form is:
(x - (-3))(2x - (-7)) = 0
(x + 3)(2x + 7) = 0
(b) So now we need to solve this. Set each of the two parenthetical expressions equal to 0:
x + 3 = 0
x = -3
AND
2x + 7 = 0
x = -7/2
These solutions mean that for these two x values, f(x) is equal to 0. It's also where the graph of f(x) crosses the x-axis.
Answer:
a) 2(x - 3)(2x - 7) = 0
b) function is 0 when x = 3 or 7/2
Step-by-step explanation:
4x² - 26x + 42 = 0
2(2x² - 13x + 21) = 0
2[2x² - 6x - 7x + 21] = 0
2[2x(x - 3) - 7(x - 3)] = 0
2(x - 3)(2x - 7) = 0

The equation y = 23.67x + 13.12 fits the scatterplot of the values for stock
ABC over the past month with an r-value of 0.9957. How much do you think
ABC will be worth at x = 28 days?
A. 13.12
B. 23.67
C. 698.74
D. 675.88
Step-by-step explanation:
The given equation is y = 23.67x + 13.12, where y is the value of the stock ABC and x is the number of days. The r-value of 0.9957 indicates a strong positive correlation between the two variables, which suggests that the equation is a good fit for predicting the value of the stock.
To find the value of the stock ABC at x = 28 days, we need to substitute x = 28 into the equation and solve for y:
y = 23.67(28) + 13.12
y = 663.76 + 13.12
y = 676.88
Therefore, the predicted value of the stock ABC at x = 28 days is $676.88.
The closest answer option is D. 675.88, but the correct answer is actually slightly higher at $676.88.
We are given a linear equation y = 23.67x + 13.12, where 'x' is the number of days and 'y' is the stock value.
Now, we need to predict the stock value for 'x' equals to 28 days. To do so, we substitute x = 28 into the equation.
Start by multiplying the given value of x with the slope:
23.67 times 28 equals 662.76.
Next, add the y-intercept to the result from the first step. So you take 662.76 and you add 13.12.
The sum is 675.88.
So, according to our calculation, the ABC stock would be worth 675.88 on the 28th day.
So, the answer is
Answer: D. 675.88.

Find the area of the regular polygon with the given apothem a and side length s.
octagon, a=66.4 in, S =55 in
Answer:
Area is 14608in²
Step-by-step explanation:
this problem is based on mensuration of flat shapes, polygon
Octagon number of sides n= 8
The expression for the area of polygon given apothem and side
Is
Area= (n*s*a)/2
Given n= 8
s= 55in
a= 66.4in
Substituting our given data we have
Area = (8*55*66.4)/2
Area = 29216/2
Area = 14608in²
The area of the regular octagon is [tex]\( 14608 \)[/tex] square inches.
The area of a regular polygon can be calculated using the formula:
[tex]\[ A = \frac{1}{2} \times a \times p \][/tex]
where [tex]\( A \)[/tex] is the area, [tex]\( a \)[/tex] is the apothem, and [tex]\( p \)[/tex] is the perimeter of the polygon.
For a regular octagon, the perimeter [tex]\( p \)[/tex] is given by:
[tex]\[ p = n \times s \][/tex]
where [tex]\( n \)[/tex] is the number of sides and [tex]\( s \)[/tex] is the length of one side. Since an octagon has 8 sides:
[tex]\[ p = 8 \times s \][/tex]
Given that [tex]\( s = 55 \)[/tex] in, we can calculate the perimeter:
[tex]\[ p = 8 \times 55 \text{ in} = 440 \text{ in} \][/tex]
Now, we can calculate the area of the regular octagon with the given apothem [tex]\( a = 66.4 \)[/tex] in and side length [tex]\( s = 55 \)[/tex] in:
[tex]\[ A = \frac{1}{2} \times a \times p \][/tex]
[tex]\[ A = \frac{1}{2} \times 66.4 \text{ in} \times 440 \text{ in} \][/tex]
[tex]\[ A = 33.2 \text{ in} \times 440 \text{ in} \][/tex]
[tex]\[ A = 14608 \text{ in}^2 \][/tex]
