Answer:
Joe Don actually ran 113.2 yards
Step-by-step explanation:
Length of the football field = 100 yd
Width of the football field = 53 yd
The football field is rectangular in shape. So in order to find the diagonal of the field, we need to split it up into two right triangles.
In one of the right triangles, the length and width becomes the two sides of it and diagonal is the third side.
In order to find the third side (diagonal), we need to apply the Pythagoras theorem.
So,
Diagonal² = 100² + 53²
Diagonal² = 10000 + 2809
Diagonal² = 12809
Taking square root on both sides
[tex]\sqrt{Diagonal^{2} } =\sqrt{12809}[/tex]
Diagonal = 113.17 yd
Diagonal = 113.2 yd (approx)
Thus Joe Don actually ran 113.2 yards

given the conversion factor 3.28 ft/ 1m which cube above has the larger surface area
cube A is 7’ cube b is 2m
Final answer:
After converting Cube B's side length to feet, Cube A has a surface area of 294 ft² while Cube B has a surface area of 258.2016 ft², making Cube A the one with the larger surface area.
Explanation:
To determine which cube has the larger surface area, we must work with a common unit of measurement for both cubes. We'll convert Cube B from meters to feet using the conversion factor 3.28 ft/1m.
For Cube A with a side length of 7 feet, the surface area (SA) is calculated by the formula SA = 6 × s² (where 's' is the side length).
SA (Cube A) = 6 × (7 ft)² = 6 × 49 ft² = 294 ft².
For Cube B with a side length of 2 meters, we first convert meters to feet: 2 m × 3.28 ft/m = 6.56 ft. So, the surface area of Cube B becomes:
SA (Cube B) = 6 × (6.56 ft)² = 6 × 43.0336 ft² = 258.2016 ft².
Between Cube A and Cube B, Cube A has the larger surface area.

dolores is selling cucumbers from her backyard garden her garden is 48 square feet in total and she can grow 1 cucumber every 72 square inches if she can successfully grow cucumbers in every square foot of the garden and sell them for $2.50 each how much will she make?
Final answer:
Dolores will make $240 by growing and selling all the cucumbers possible in her 48 square feet garden, with each cucumber selling for $2.50.
Explanation:
To calculate the amount of money Dolores will make from selling cucumbers, we need to determine how many cucumbers she can grow in her 48 square feet garden, and then multiply that number by the selling price of $2.50 per cucumber. First, we'll convert the area of her garden into square inches since we know a cucumber takes up 72 square inches of space:
48 square feet × 144 square inches per square foot = 6,912 square inches.
Next, we divide this by the amount of space needed for one cucumber to find the total number of cucumbers she can grow:
6,912 square inches ÷ 72 square inches per cucumber = 96 cucumbers.
Finally, we'll multiply the number of cucumbers by the selling price:
96 cucumbers × $2.50 per cucumber = $240.
Therefore, Dolores will make $240 by selling all the cucumbers she can grow in her garden.
A doctor's office mails a survey to each of its patients. The results of the survey are based off of the total number of patients.
Which of the following could affect the outcome of their surveys?
A.The results could be flawed because the sample population was too large.
B.The results could be flawed due to a wide range of topics in the questions.
C.The survey is biased because they are only asking patients.
D.The results could be flawed due to non-response of patients.
Answer:
The results could be flawed due to non-response of patients.
Step-by-step explanation:
A doctor's office mails a survey to each of its patients. The results of the survey are based off of the total number of patients. The office is mailing the patients. It is very likely that patients do not read out the survey mail. So, they cannot respond to the survey or a very few patients will respond back. So, option 4th is the correct. The results could be flawed due to non-response of patients.

You
Friend
You
The image shows a tape diagram with two sections labeled "You" and "Friend". The "You" section is longer than the "Friend" section, indicating that you tutored for more hours than your friend.
To find the number of hours that you tutored, we can divide the total number of hours tutored (12 hours) by the number of sections in the tape diagram (2).
Number of hours you tutored = 12 hours / 2 sections = 6 hours
Therefore, you tutored for 6 hours.
Explanation of tape diagrams:
A tape diagram is a visual representation of a mathematical equation. It is a horizontal bar that is divided into sections, with each section representing a different quantity. The length of each section represents the size of the quantity it represents.
Tape diagrams can be used to solve a variety of mathematical problems, including addition, subtraction, multiplication, and division problems. They are especially useful for solving problems that involve multiple quantities, as they can help to visualize the relationships between the different quantities.
In this case, the tape diagram is used to solve the following problem:
> You and a friend tutor for a total of 12 hours. Use the tape diagram to find how many hours you tutor.
The tape diagram is divided into two sections, one for you and one for your friend. The length of each section represents the number of hours that each person tutored. Since you tutored for more hours than your friend, the "You" section is longer than the "Friend" section.
To find the number of hours that you tutored, we can divide the total number of hours tutored (12 hours) by the number of sections in the tape diagram (2). This gives us the number of hours that you tutored, which is 6 hours.
Therefore, the answer to the question is "You tutored for 6 hours."

What is Quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x²(a>0) for an equation to be a quadratic equation. The x² term is written first when constructing a quadratic equation in standard form, then the x term, and finally the constant term. The numerical values of a, b, and c are often expressed as integral values rather than fractions or decimals.
Given Equation:
h(t) = –16t² + 14t

A roller coaster car follows a parabolic path over the first hill on its track. The height of the car, in feet, t seconds after the ride starts can be shown by the function given below.
h ( t ) = -3t^2 + 15t + 18
Which of the statements is true?
* The domain of the function is [0, 6], and it represents the car's time to reach maximum height.
* The domain of the function is [-1, 6], and it represents the car's time to reach maximum height.
* The domain of the function is [0, 6], and it represents the car's time to complete the hill.
* The domain of the function is [-1, 6], and it represents the car's time to complete the hill.
None of the options are entirely correct. The domain of the function is [tex]\( t \geq 0 \)[/tex] , and it does not directly represent the time to complete the hill or reach maximum height.The domain is representing all real numbers. The function doesn't directly indicate completion time or maximum height.
Let's analyze the given function [tex]\( h(t) = -3t^2 + 15t + 18 \)[/tex] to determine the domain and its meaning:
1. **Domain of the function**:
The domain of a quadratic function is all real numbers unless there are restrictions. In this case, there are no restrictions mentioned in the problem, so the domain is all real numbers. However, in the context of the roller coaster ride, the time ( t ) cannot be negative because it doesn't make sense for time to be negative in this scenario. Therefore, the practical domain is [tex]\( t \geq 0 \).[/tex]
2. **Time to reach maximum height**:
The time to reach the maximum height of the roller coaster can be found using the vertex formula: [tex]\( t = -\frac{b}{2a} \)[/tex] , where [tex]\( a = -3 \) and \( b = 15 \)[/tex] (coefficients from the quadratic function). Substituting these values into the formula:
[tex]\[ t = -\frac{15}{2(-3)} = -\frac{15}{-6} = \frac{15}{6} = \frac{5}{2} \][/tex]
Since time cannot be negative in this context, the time to reach the maximum height is [tex]\( t = \frac{5}{2} = 2.5 \)[/tex] seconds.
Now, let's analyze the given options:
- **Option 1: The domain of the function is [0, 6], and it represents the car's time to reach maximum height.**
- The domain given is correct [tex](\( t \geq 0 \)),[/tex] but it incorrectly states that it represents the time to reach maximum height. The correct time to reach maximum height is [tex]\( t = 2.5 \)[/tex] seconds, not 6 seconds.
[tex]\( t \geq 0 \),[/tex]
- **Option 2: The domain of the function is [-1, 6], and it represents the car's time to reach maximum height.**
- This option gives an incorrect domain. The domain is [tex]\( t \geq 0 \), not \( t \geq -1 \).[/tex]
- **Option 3: The domain of the function is [0, 6], and it represents the car's time to complete the hill.**
- This option correctly identifies the domain as [tex]\( t \geq 0 \).[/tex] However, it incorrectly states that it represents the time to complete the hill. The function does not directly represent the time to complete the hill; it represents the height of the car at any given time.
- **Option 4: The domain of the function is [-1, 6], and it represents the car's time to complete the hill.**
- This option gives an incorrect domain. The domain is [tex]\( t \geq 0 \),[/tex] not [tex]\( t \geq -1 \).[/tex]
Therefore, none of the options are entirely correct. The domain of the function is [tex]\( t \geq 0 \)[/tex] , and it does not directly represent the time to complete the hill or reach maximum height.

The area of the rectangle shown is given by the function A(x) = 2x2 - 5x. If the width of the rectangle is 13, what is the area
The area of the rectangle is 273 square units.
The task is to find the area of a rectangle where the width of the rectangle is given as 13, and the area as a function of x is provided as A(x) = 2x² - 5x.
To find the area, we need the value of x that corresponds to the width. Since the width is 13, we set x as 13 and substitute it into the area function.
A(13) = 2(13)² - 5(13) = 2(169) - 65 = 338 - 65 = 273 square units.
Thus, the area of the rectangle is 273 square units.

Answer:
$1386.
Step-by-step explanation:
We have been given that Zack deposited $1,200 in a savings account that paid 7.75% simple interest. We are asked to find the balance in his account at the beginning of the third year.
The balance in the account at the beginning of the third year will be equal to balance in the account at the end of 2nd year.
We will use simple interest formula to solve our given problem.
[tex]A=P(1+rt)[/tex], where,
A = Amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
t = Time in years.
Upon converting our given interest rate in decimal form we will get,
[tex]7.75\%=\frac{7.75}{100}=0.0775[/tex]
Upon substituting our given values in simple interest formula we will get,
[tex]A=\$1200(1+0.0775\cdot 2)[/tex]
[tex]A=\$1200(1+0.155)[/tex]
[tex]A=\$1200(1.155)[/tex]
[tex]A=\$1386[/tex]
Therefore, an amount of $1386 will be in Jack's account at the beginning of third year.
