You run around the perimeter of a baseball field at a rate of at most 8 feet per second. Which of the following are possible amounts of time that it takes you to run around the baseball field?

The possible amount of time is 90 seconds that it takes you to run around the baseball field
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
The options are missing.
The options are:
90 seconds100 seconds110 seconds120 secondsWe have a radius of the circle is:
r = 150 ft
The perimeter of the circle = 2πr = 2π(150) = 300π ft
The running path distance = 40% of the perimeter of the circle
= 40% of 300π
= 120π ft
Assume the tape length is 50 m
Total distance = 200 + 200 + 120π - 50 = 726.99
The rate is 8 feet per second.
Time = distance/rate = 726.99/8 = 90.87 ≈ 90 seconds
Thus, the possible amount of time is 90 seconds that it takes you to run around the baseball field

Prism A and Prism B have the same volume. Which could be the dimensions of prism B. Please help!
Answers
Question : Prism A and Prism B have the same volume. Which could be the dimensions of prism B?
Prism A :
Length = 8 feet
Width = 4 feet
Height = 5 feet
Prism B:
Length = ? feet
Width = ? feet
Height = ? feet
Option 1:
Length = 6 feet
Width = 10 feet
Height = 2 feet
Option 2:
Length = 4 feet
Width = 4 feet
Height = 10 feet
Option 3:
Length = 5 feet
Width = 4 feet
Height = 7 feet
Option 4:
Length = 8 feet
Width = 4 feet
Height = 6 feet
Here, the dimensions of the prism B will be length = 4 feet, width = 4 feet, and height = 10 feet.
We know that if the a and b be the length and width of the base respectively and c be the height of a prism, then the volume of the prism is abc.
Given that
length of 1st prism = 8 feet
width of 1st prism = 4 feet
height of 1st prism = 5 feet
So volume of 1st prism = 8 * 4 * 5 = 160 feet³
Now the volume of 1st and 2nd prisms are the same.
So, we have to check the options for length, width, and height of the 2nd prism.
1st option:
Height = 6 feet
Width = 10 feet
Length = 2 feet
So, volume = 6 * 10 * 2 = 120 feet³
Then the 1st option is incorrect.
2nd option:
Height = 4 feet
Width = 4 feet
Length = 10 feet
So, volume = 4 * 4 * 10 = 160 feet³
Then the 2nd option is correct.
Therefore, the dimensions of the prism B will be length = 4 feet, width = 4 feet, and height = 10 feet. The 2nd option is correct.

The difference of two numbers is 8, and the sum of the squares of these two numbers are 320. what are the numbers
Answers
Answer:
There are two sets of numbers that meet the criteria:
1) 8 and 16, or
2) -8 and -16
Step-by-step explanation:
Let's call the two numbers A and B.
We are told:
1) A-B=8, and
2) A^2 + B^2 = 320
Rearrange 1) to solve for A:
A=8+B
Use this value of A in the second equation:
A^2 + B^2 = 320
(8+B)^2 + B^2 = 320
(64+ 16B + B^2) + B^2 = 320
2B^2 + 16B + 64 = 320
B^2 + 8B + 32 = 160
B^2 + 8B + 32 = 160
B^2 + 8B - 128 = 0
(B+16)(B-8)=0
B is either -16 or +8
Assuming B = 8
Then from A-B=8 we find that A = B+8 and A = 16
Does A^2 + B^2 = 320?
(16)^2 + (8)^2 = 320?
256 + 64 = 320? YES
--------------------------------
Assuming B=-16
If B=-16, then from A-B=8 we find that A = 8+(-16) and A = -8
Does A-B=8?
-8 - (-16) = 8? YES
Does A^2 + B^2 = 320?
(-8)^2 + (-16)^2 = 320?
64 + 256 = 320? YES

If each set on sale contains 10 glasses, write and solve an inequality which can be used to determine x, the number of sets of glasses Victoria could buy for the restaurant to have enough glasses.
Answers
Using a linear function, we have that:
The inequality is: [tex]368 + 10x \geq 673[/tex].The solution is: [tex]x \geq 31[/tex].What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Since there are currently 368 glasses(y-intercept), and each set on sale comes with 10 glasses(slope), the number of glasses after x sales is given by:
y = 368 + 10x.
She needs at least 673 glasses, hence the inequality is:
[tex]y \geq 673[/tex]
[tex]368 + 10x \geq 673[/tex].
Now we solve the inequality to find the number of sets needed:
[tex]10x \geq 305[/tex]
[tex]x \geq 30.5[/tex]
As the number of sets is an integer number, the solution is:

Which statement about the function is true?
O The function is increasing for all real values of x
where
x<-4.
Answers
Answer:
A.) The function is increasing for all real values of x where x < -4
Step-by-step explanation:
On the interval x < -4, all of the x values are increasing. Before x = -4, the line assumes a positive slope because it is heading upwards. After this interval, the function is decreasing because the slope is heading downwards.
On the interval -6 < x < -2, all of the x values are positive because they lie above the x-axis. This does not necessarily mean that all of the values are increasing.
On the interval x < -6 and x > -2, all of the x values are negative because they lie below the x-axis.

Answers
5x²+20x+16y-15=0 is the equation, in vertex form, for the given parabolas.
We need to determine the equation, in vertex form, for the following parabolas.
How to find the equation, in vertex form?We can find the parabola's equation in vertex form following two steps:
Step 1: Use the (known) coordinates of the vertex, (h,k), to write the parabola's equation in the form: y=a(x−h)²+k.
Step 2: Find the value of the coefficient a by substituting the coordinates of the point into the equation written in step 1 and solving for a.
Now, substitute (−2, 5) in y=a(x−h)²+k
⇒y=a(x−(-2))²+5
Now, substitute (2, 0) in y=a(x−(-2))²+5.
0=a(2+2)²+5
⇒a=-5/16
So, y=-5/16(x+2)²+5
⇒16y=-5(x²+4x+4)+5
⇒16y=-5x²-20x-20+5
⇒5x²+20x+16y-15=0.
Therefore, 5x²+20x+16y-15=0 is the equation, in vertex form, for the given parabolas.

George bought socks for "$"300 and planned to sell them for $6 a pair. write an inequality to find the minimum number of socks he has to sell in order to make a profit of more than 210.
Answers
The inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.
In the question, we are given that George bought socks for $300.
Therefore, George's total cost = $300.
We assume the number of pairs of socks George sells to be s.
The unit price per pair quoted by George = $6
Therefore, George's total sales = $6s.
We know that the profit over a transaction is given as the difference between sales and costs, that is,
The profit = The total sales - the total costs,
or, profit = 6s - 300.
In the question, we are required to make a profit of more than 210.
This can be shown by the inequality,
6s - 300 > 210.
Thus, the inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.
