Answer:
The difference in finishing time between the 2nd and 3rd places is the shortest and it is 0.07 seconds.
Step-by-step explanation:
The first positioned swimmer took 55.98 seconds and the second positioned swimmer took 56.87 seconds to complete the race.
So, the difference is (56.87 - 55.98) = 0.89 seconds.
The second positioned swimmer took 56.87 seconds and the third positioned swimmer took 56.94 seconds to complete the race.
So, the difference is (56.94 - 56.87) = 0.07 seconds.
The third positioned swimmer took 56.94 seconds and the fourth positioned swimmer took 57.17 seconds to complete the race.
So, the difference is (57.17 - 56.94) = 0.23 seconds.
The fourth positioned swimmer took 57.17 seconds and the fifth positioned swimmer took 57.27 seconds to complete the race.
So, the difference is (57.27 - 57.17) = 0.10 seconds.
The fifth positioned swimmer took 57.27 seconds and the sixth positioned swimmer took 57.35 seconds to complete the race.
So, the difference is (57.27 - 57.35) = 0.08 seconds.
Therefore, the difference in finishing time between the 2nd and 3rd places is the shortest and it is 0.07 seconds. (Answer)

A bank offers a CD that pays a simple interest rate of 6%. How much must you put in this CD now in order to have $11 comma 700 to replace all the windows in your house in 5 years?
Answer:
You should invest US$ 9,000 in the CD to replace all the windows in your house.
Step-by-step explanation:
Let's recall that the simple interest formula is:
A = P * (1 + r * t), where,
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
Replacing with the real value, we have:
11,700 = P * (1 + 0.06 * 5)
11,700 = P * (1.3)
P = 11,700/1.3
P = 9,000
You should invest US$ 9,000 in the CD to replace all the windows in your house in 5 years.
To calculate the initial deposit for a CD with a 6% simple interest rate in order to have $11,700 in 5 years, you can use the simple interest formula. The formula is rearranged to solve for the initial deposit amount: P = I / RT, where 'P' is the initial deposit, 'I' is the desired amount, 'R' is the interest rate, 'T' is the CD term.
Explanation:The subject of the question is about how much initial deposit you must put into a CD with a simple interest rate of 6% in order to have $11,700 in 5 years. You can find this out by using the formula for simple interest, which is I = PRT. 'I' is the interest, 'P' is the principal amount (what you want to find out), 'R' is the rate of interest, and 'T' is the time in years.
Since you want to find out 'P' (the principal amount), you'd rearrange the formula to P = I / RT. Now you substitute 'I' with $11,700, 'R' with 0.06 (6% expressed as a decimal), and 'T' with 5 years. So, P = $11,700 / (0.06 * 5). From this calculation, you'll be able to determine how much money you need to deposit now into your CD to reach your goal.

Each bag of candy the factory makes contains 120 pieces of chocolate candy. This week, the factory produced 1800 pieces. Solve the equation below for p to find the number of bags of candy the factory produced. 120p = 1800
Answer:
15 bags
Step-by-step explanation:
120p = 1800
p = 1800/120 =180/12 = 15
Final answer:
To find the number of bags of candy produced, divide 1800 by 120 to get p, which results in p = 15, indicating the factory made 15 bags of candy.
Explanation:
The student is asked to solve the equation 120p = 1800 for p to find out the number of bags of candy the factory produced. In order to find p, we need to perform algebraic operations to isolate the variable on one side of the equation. Here's the step-by-step solution:
Therefore, the factory produced 15 bags of candy.

On Tuesday, a local hamburger shop sold a combined total of 600 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the
number of hamburgers sold. How many hamburgers were sold on Tuesday?
Answer:
Step-by-step explanation:
h + c = 600
c = 3h
now we sub
h + 3h = 600
4h = 600
h = 600/4
h = 150 <=== hamburgers sold on Tuesday
c = 3h
c = 3(150)
c = 450....and 450 cheeseburgers sold

The table compares the initial amount of fuel Li Jing's car had, and the total distance she traveled using that amount, in several different occasions.
Can the total distance be represented as a function of fuel?
Fuel (liters) 1st # , Distance (kilometers) 2nd #
30 100
35 120
40 140
35 120
45 160
25 90
30 100
20 80
Yes or No and why?
Answer:
answer is yes
Step-by-step explanation:
Yes, the total distance can be represented as a function of fuel. The relationship between the two variables can be represented by a linear function. By calculating the slope and y-intercept of the line, we can determine the equation representing the total distance as a function of fuel. which is y = 4x - 20
Explanation:Yes, the total distance can be represented as a function of fuel. In this case, the fuel can be considered as the independent variable and the total distance as the dependent variable. By analyzing the table, we can observe that as the amount of fuel increases, the total distance also increases. This relationship can be represented using a linear function, since the data points seem to form a straight line.
A linear function can be written in the form y = mx + b, where y represents the total distance, x represents the amount of fuel, m represents the slope of the line (which indicates how the total distance changes with each unit of fuel), and b represents the y-intercept (which represents the initial distance when there is no fuel).
By calculating the slope of the line using two data points, we can determine the equation of the linear function. For example, using the first and second data points, we can calculate the slope as:
m = (120 - 100) / (35 - 30) = 20 / 5 = 4
With this information, we can write the function representing the total distance as a function of fuel:
y = 4x + b
To determine the value of b (the y-intercept), we can select any data point and substitute the values of x and y into the function. Let's use the first data point:
100 = 4(30) + b
Solving this equation, we find that b = -20.
Therefore, the equation representing the total distance as a function of fuel is:
y = 4x - 20

Below is a map of Yellowstone Park. The scale for the map is 1cm = 25 miles.
Mrs. Fowler went on a trip from Old Faithful to Canyon.
What is the actual distance from Old Faithful to Canyon in MILES?
A 5 miles
B 62.5 miles
C 15 miles
D 75 miles
Answer:
Option D. 75 miles
Step-by-step explanation:
Looking at the Yellowstone Park map we can see that Mrs. Folwer went from Old Faitful to the Canyon by covering a straight line of [tex]3cm[/tex].
This tells us that we do not need extra calculations to find the distance covered on the map. We also know that the map scale is given as [tex]1cm=25miles[/tex]. So similarly we do not need to do extra ratio conversions.
Thus we know that if [tex]1cm=25miles[/tex] and she covered [tex]3cm[/tex] on the map, we can just multiply covered distance with the equivalency of [tex]cm[/tex] in [tex]miles[/tex] as follow:
[tex]Distance=(3cm) (25 miles)=75miles[/tex]
Thus Mrs. Folwer's actual distance from Old Faithful to Canyon in Miles is 75 miles. (which is given in Option D.)

Choose 1 answer:
Only (-3,3)
Only (–2, 2)
Both (–3, 3) and (-2, 2)
Neither
Neither of the ordered pairs is a solution to the equation y = 4x + 9.
The correct option is Neither.
Which of the ordered pairs is a solution?Given the equation in the question:
y = 4x + 9
To determine which ordered pair is a solution of the equation y = 4x + 9, you can plug each pair into the equation and see if it holds true.
y = 4x + 9
For (-3, 3):
y = 4x + 9
Plug in the x and y values:
3 = 4(-3) + 9
3 = -12 + 9
3 = -3
(-3, 3) is not a solution.
For (-2, 2):
y = 4x + 9
Plug in the x and y values:
2 = 4(-2) + 9
2 = -8 + 9
2 = 1
(-2, 2) is not a solution.
