Answer:
9 tables
Step-by-step explanation:
Let x be the number of chairs sold and y be the number of tables sold.
Chairs are sold for $100 each, then x chairs cost $100x.
Tables are sold for $550 each, then y tables cost $550y.
Every day, the store can ship at most 21 pieces of furniture, then
[tex]x+y\le 21[/tex]
Store must sell no less than $5,700 worth of chairs and tables, then
[tex]100x+550y\ge 5,700[/tex]
If 10 chairs were sold, then [tex]x=10.[/tex] Substitute this value into both inequalities:
1. [tex]10+y\le 21\Rightarrow y\le 11[/tex]
2. [tex]100\cdot 10+550y\ge 5,700\Rightarrow 550y\ge 4,700\Rightarrow y\ge \dfrac{470}{55}=8\dfrac{6}{11}[/tex]
Hence, [tex]8\dfrac{6}{11}\le y\le 11[/tex]
The minimum number of tables that the the store must sell in order to meet the requirements is 9 tables

Write an equation in point-slope form for the line passing through the given point with the given slope. (5,2) m=3
Answer:
y - 2 = 3(x - 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 3 and (a, b) = (5, 2), thus
y - 2 = 3(x - 5) ← equation of line
Answer:
y - 2 = 3(x - 5)
Step-by-step explanation:
Start with the general point-slope equation:
y - k = m(x - h)
Now substitute 2 for k, 5 for h and 3 for m:
y - 2 = 3(x - 5)

A line passes through the point (9. -9) and has a slope of -4/3.
Write an equation in point-slope form for this line.
Answer:
[tex]y = \frac{ - 4}{3} x + 3[/tex]
Step-by-step explanation:
[tex]using \: point \: slope \: form \\ y - y1 = m(x - x1) \\ y + 9= \frac{ - 4}{3} (x - 9) \\ y + 9= \frac{ - 4}{3}x + 12\\ y = \frac{ - 4}{3} x + 3[/tex]
The equation of the line in point-slope form passing through (9, -9) with a slope of -4/3 is y + 9 = -4/3 * (x - 9).
Explanation:
The point-slope form of a line's equation is expressed as y - y1 = m(x - x1). In this equation, 'm' represents the line's slope and (x1, y1) defines a particular point through which the line passes. In this scenario, the slope is given as '-4/3' and the point (9, -9). Consequently, by substituting these parameters into the point-slope form, we obtain the equation y - (-9) = (-4/3)(x - 9) or y + 9 = -4/3 * (x - 9).

- © MP.6 Be Precise Anna's family had a
party in a restaurant. Their food bill was
$214.58. The tip for the servers was found
by multiplying the food bill by 0.18. What
was the cost of the food bill and tip before
ales tax? Round to the nearest cent.
MP.1 Make Sense and Persevere
ghan's vegetable garden is pictured
w. What is its area?
We can see here that the cost of the food bill and tip before sales tax was approximately $253.20.
To find the cost of the food bill and tip before sales tax, you first need to calculate the tip amount and then add it to the food bill.
Given:
Food bill = $214.58
Tip rate = 0.18 (18% expressed as a decimal)
First, calculate the tip amount:
Tip = Food bill × Tip rate
Tip = $214.58 × 0.18
Tip = $38.6244 (rounded to two decimal places)
Tip ≈ $38.62
Now, add the food bill and the tip to find the total cost before sales tax:
Total cost = Food bill + Tip
Total cost = $214.58 + $38.62
Total cost = $253.20
Therefore, the cost of the food bill and tip before sales tax was approximately $253.20.
Nola was selling tickets. At the end of the evening she picked up the cash box and noticed a dollar on the floor and wonder if it was supposed to be in the box
The price of tickets for the Dance was 1$(for individuals) or 2 tickets for 8$(for couples) she looked inside the cash box and found 200$ and ticket subs for the 47 students in attendance, does the dollar nola found on the ground belong in the box ?
Let X = Individual ticket and y = couples tickets.
Set up two equations:
X + Y = 47 tickets sold
1X + 8y = $200
Rewrite the first equation as X = 47-y
Replace x in the second equation and solve:
1(47-y) = 8y = 200
Simplify:
47 - y + 8y = 200
Combine like terms:
47 +7y = 200
Subtract 47 from both sides:
7y = 153
Divide both sides by 7:
y = 153 / 7
y = 21.857
Because Y does not equal a whole number, the extra dollar does belong in the box.
Final answer:
Given the ticket prices and attendance, total sales amount to $71. The extra dollar found doesn't fit this, so it shouldn't be in the box.
Explanation:
To determine if the dollar Nola found belongs in the box, let's analyze the ticket sales. With individual tickets priced at $1 and couples tickets at $8 for two, we can calculate the total number of tickets sold. If there were 47 students in attendance, and assuming each couple bought the couples' ticket deal, the number of individual tickets sold would be (47 - number of couples) * 2 + number of couples.
Since each couple buys two tickets, the number of couples is 47 / 2 = 23.5, which means there were 23 couples and 1 individual. So, the total number of tickets sold is (47 - 23) * 2 + 23 = 71. Thus, the revenue from ticket sales should be $71.
If the cash box contains $200 and ticket sales total $71, then the extra dollar Nola found does not belong in the box. It's possible someone overpaid for a ticket or dropped a dollar accidentally, but it shouldn't be included in the revenue from ticket sales. Therefore, Nola should keep the dollar aside, perhaps to return it to its rightful owner.

Answer:
The first option:
Prove that the area of the two small squares combined is equal to the area of the larger square
Step-by-step explanation:
The Pythagorean Theorem in an equation would be:
a² + b² = c²
Where:
c = hypotenuse (longest side of the triangle)
a and b = two other legs of the triangle
The theorem states that the sum of the squares of the shorter sides is equal to the square of the longest side in a right triangle or a triangle that has a right angle (90°)
Let's say that we have a right triangle with the lengths of 3cm , 4cm, and 5cm.
(3cm)² + (4cm)² = (5cm)²
9cm² + 16cm² = 25cm²
25cm² = 25cm²
Look at the attached image to see what happens when we draw the squares of each leg.
A town in east Texas received 20 inches of rain in two weeks. If it kept raining at this rate for a 31−day month, how much rain did the town receive? Round your answer to the nearest inch. The town received approximately inches of rain during a 31−day month
Answer:
The town received approximately 44.29 inches of rain during a 31−day month.
Step-by-step explanation:
Given;
The amount of rain for two weeks = 20 inches.
For finding amount of rain for 31 days, we use the unitary method.
∵ Amount of rain for 14 days = [tex]20\ inches[/tex]
∴ Amount of rain for 1 day = [tex]\frac{20\ inches}{14}[/tex]
∴ Amount of rain for 31 day = [tex]\frac{20\ inches}{14}\times31=\frac{620}{14}\ in=44.285\approx 44.29\ in[/tex]
Hence the amount of rain the town received is 44.29 inches approximately.

Two factory plants are making TV panels. Yesterday, Plant A produced 16,000 panels. Five percent of the panels from
Plant A and 2% of the panels from Plant B were defective.
How many panels did
Plant B produce, if the overall percentage
of defective panels from the two plants was 4%?
Please help
Plant B produced 8000 panels.
Let's denote the number of panels produced by Plant B as B .
The total number of defective panels from Plant A is [tex]\( 0.05 \times 16000 = 800 \)[/tex] , and the total number of defective panels from Plant B is [tex]\( 0.02 \times B \)[/tex].
The total number of panels from both plants is 16000 + B .
The overall percentage of defective panels is given as 4%, so:
[tex]\[ \frac{800 + 0.02 \times B}{16000 + B} = 0.04 \][/tex]
Now, let's solve for B :
[tex]\[800 + 0.02 \times B = 0.04 \times (16000 + B) \][/tex]
[tex]\[ 800 + 0.02 \times B = 640 + 0.04 \times B \][/tex]
Subtracting [tex]\( 0.02 \times B \)[/tex] from both sides:
[tex]\[ 800 = 640 + 0.02 \times B \][/tex]
Subtracting 640 from both sides:
[tex]\[ 160 = 0.02 \times B \][/tex]
Now, divide by 0.02 to find B :
[tex]\[ B = \frac{160}{0.02} \][/tex]
B = 8000
So, Plant B produced 8000 panels.
The number of panels produced by Plant B is 8,000.
The number of panels produced by Plant A = 16,000
The number of defective panels from A = 5%
Now, 5% of 16,000 =
So, out of 16,000 panels produced by pant A , 800 are defective. .. (1)
Let us assume number of panels produced by Plant B = m
The number of defective panels from B = 2%
Now, 2% of m
So, out of total m panels produced by pant B , 0.02 m are defective. .. (2)
Now, total panels produced over all = Panels by A + Panels by B
= 16,000 + m
The percentage of defective panels over all = 4%
Now, 4% of (16,000 + m)
Also, the total number of defective panels = Defective from A + Defective from B
⇒(0.04)(16,000 + m) = 800 + 0.02 m from (1) and (2)
0.02 m = 160
⇒ m = 160 /0.02 = 8,000
or, m = 8,000
Hence, Number of panels produced by Plant B is 8,000.

Use an example to describe the multiplicative relationship between two equivalent ratios
Answer:
Step-by-step explanation:
5/10 and 1/2 are both equivalent ratios resulting in half of themselves you can multiply these by any numbers but they will stay as half ratios such as 1:2 x 6 it would be 6:12 divide it by 6 and you have a half
Equivalent ratios have a multiplicative relationship, where multiplying both terms of a ratio by the same number results in another equivalent ratio. For example, multiplying the ratio 1:2 by 2 gives the equivalent ratio 2:4, showing that the ratios are proportional to each other.
Explanation:Understanding Equivalent Ratios through Multiplication
We can explore the concept of equivalent ratios by looking at their multiplicative relationship. For instance, let's consider the ratios 1:2 and 2:4. These two ratios are equivalent because if we multiply both terms of the first ratio by 2, we get the second ratio. Mathematically, this can be expressed as 1x2/2x2 = 2/4, which is the same as the second ratio. Hence, the multiplication of both the numerator and the denominator of the first ratio by the same number (in this case, 2) maintains the ratio's equivalence to the second ratio.
This concept is crucial when dealing with proportions, unit rates, and unit scales. For example, if a map uses a unit scale of 1 inch = 100 feet, doubling the distance on the map to 2 inches would also double the actual distance to 200 feet, showing a direct multiplicative relationship between the two equivalent ratios.
Understanding how to use multiplication to find equivalent ratios is fundamental in solving problems that involve scaling, such as converting units or working with maps and models.
