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.
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.

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.
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).

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.

Deb has 26 ounces of shredded cheese. She is making 4 small loaves of garlic cheese bread . How many ounces of cheese can deb use in each loaf of bread. Explain your reasoning
Deb can use 6.5 ounces of cheese per loaf of bread. The calculation is made by dividing the total amount of cheese by the number of loaves.
Explanation:Deb has 26 ounces of shredded cheese and she is making 4 small loaves of garlic cheese bread. To equally distribute the cheese across each loaf, we perform division.
We divide the total amount of cheese by the number of loaves: Thus, 26 ounces divided by 4 loaves equals 6.5 ounces of cheese per loaf.
The reasoning here is simple: we are equally distributing the cheese across each loaf, so we divide the total amount by the number of loaves. This ensures each loaf gets the same amount of cheese.

The unit rate is
nothing calorie(s) per cup.
(Simplify your answer. Type an integer, proper fraction, or mixed number.)
Step-by-step explanation:
A box of cereal states that there are 93 calories in a three fourths-cup serving. What is the unit rate for calories per cup?
126.7 ~= 127 calories
How many calories are there in 2 cups of the cereal?
127 *2 = 254 calories.
The unit rate for calories per cup is 124 calories and 2 cups of the cereal contain 248 calories.
What is Unitary Method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given is a box of cereal which states that there are 93 calories in a
(3/4)th of a cup serving.
We can write -
3/4 cup serving contain → 93 calories
1 cup serving will contain → (93 x 4)/3 which is equivalent to 124 calories
Similarly, we can calculate for 2 cups of serving as -
1 cup → 124 calories
2 cups → (2 x 124) = 248 calories
Therefore, the unit rate for calories per cup is 124 calories and 2 cups of the cereal contain 248 calories.

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.
9. Mr. Tran gained 5 lbs of solid fast twitching muscles during his last bulking phase lasting 24 days. If this rate
continues, how much muscle will he gain in a 36 days bulking phase?
Answer:
7.5 pounds of muscles.
Step-by-step explanation:
Mr. Tan gained 5 pounds of solid fast twitching muscles during his last bulking phase lasting 24 days.
If this rate remains the same, then we can use the unitary method to calculate the amount of muscle he will gain in 36 days bulking phase.
Hence, within 24 days of the bulking phase, he gains 5 pounds of muscles.
So, within 36 days of the bulking phase, he will gain [tex]\frac{5}{24} \times 36 = 7.5[/tex] pounds of muscles. (Answer)
First, we calculated Mr. Tran's rate of muscle gain by dividing the total amount gained by the number of days. We then applied this rate to the asked time frame of 36 days. The result was approximately 7.48 lbs of muscle gain.
Explanation:To solve this problem, we need to determine the rate of gain. Mr. Tran gained 5 lbs of solid fast twitching muscles in 24 days, so his rate of gain is 5 lbs / 24 days = 0.208 lbs/day. If Mr. Tran continues this rate for an extended period of 36 days, we can calculate the total gain by multiplying his daily rate by the number of days, i.e., 0.208 lbs/day * 36 days = 7.48 lbs. rounded to two decimal places.
So, if Mr. Tran’s bulking phase continues at the same rate for 36 days, he will gain approximately 7.48 lbs of muscle.

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

An online furniture store sells chairs for $100 each and tables for $550 each. Every day, the store can ship at most 21 pieces of furniture and must sell no less than $5700 worth of chairs and tables. If 10 chairs were sold, determine the minimum number of tables that the the store must sell in order to meet the requirements. If there are no possible solutions, submit an empty answer.
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]
