The line of 75 paper clips end to end would be 93 3/4 inches long.
To calculate the total length of the line formed by laying 75 paper clips end to end, we need to find the sum of the lengths of all the paper clips.
Each paper clip is 1 1/4 inches long. To add these lengths together, we can convert 1 1/4 to an improper fraction, which is 5/4 inches.
Now, multiply the length of one paper clip (5/4 inches) by the number of paper clips (75):
Total length = (5/4) inches * 75
Next, multiply the whole number (75) by the numerator (5) and add it to the product of the denominator (4) and the whole number:
Total length = (75 * 5 + 0) / 4
Total length = 375/4
Now, we can simplify the fraction:
Total length = 93 3/4 inches
The line of 75 paper clips end to end would be 93 3/4 inches long.

The arch of a bridge forms a parabola with the function \displaystyle f(x)=-0.05(x-30)^{2}+45f(x)=−0.05(x−30) 2 +45 where x is the horizontal distance (in meters) from the arch's left end and y is the height (in meters) above the road. How many meters high is the arch at its highest point?
Answer:
40mStep-by-step explanation:
If the arch of a bridge forms a parabola with the function
f(x)=−0.05(x−30)² +45 where x is the horizontal distance;
The arc is at its highest point at when df(x)/dx = 0
df(x)/dx = -2(0.05)(x-30)(1) + 0
df(x)/dx = -0.1(x-30)
df(x)/dx = -0.1x+3
Since df(x)/dx = 0
-0.1x+3 = 0
-0.1x = -3
x = -3/-0.1
x = 20
Substitute x = 20 into the function as shown:
f(x)=−0.05(x−30)² +45
f(20)=−0.05(20−30)² +45
f(20)=−0.05(-10)² +45
f(20)=−0.05(100) +45
f(20)=-5+45
f(20) = 40
Hence the arch is 40meters high at its highest point

A shop sells bagels for $5 per dozen. You can use the table to answer
the questions. Explain your reasoning. (Show all your work)
1. At this rate, how much would 6 bagels cost?
2. How many bagels can you buy for $50?
Answer with step-by-step explanation:
Lets says the number of bagels is B and the price in dollars is D.
Equation: D × 12/5 = B
1. 6 is half of a dozen, which means the price would be half of 5, 2.5
2. $50 is 10× the amount of $5, so the amount of bagels would be 10 × 12, which is 120 bagels.
Hope this helped! (brainliest please)
A Dozen mathematically means 12.
It is important to note that:
$5 = 12 bagels
1) 12 bagels = $56 bagels = ?
Cross Multiply
6 bagels x $5 / 12
= $7.50
Therefore, 6 bagels would cost $7.50
2) $5 = 12 bagels$50 = ?
Cross multiply

A sales person in a stereo store is given a choice of two different compensation plans. One plan offers a weekly salary of $250 plus a commission of $25 for each stereo sold. The other plan offers no salary but pays $50 commission on each stereo sold. How many stereos must the sales person sell to make the same amount of money under both plans ?
Answer:
The salesperson needs to sell 10 stereos to make the same money on both plans
Step-by-step explanation:
We'll analyze both choices for the compensation plans of a salesperson.
One plan offers a fixed weekly salary of $250 plus a $25 commission for each stereo sold. The function than models this plan is:
P1=250+25x
Where x is the number of stereos sold.
The other plan offers no fixed salary but a $50 commission on each stereo sold. The function of this plan is:
P2=50x
To find the equilibrium point for both plans, we make P1=P2:
250+25x=50x
Simplifying:
25x=250
Solving:
x = 250 / 25 = 10
The salesperson needs to sell 10 stereos to make the same money on both plans

A civil engineer wants to know the opinions of drivers about online driving tests. She obtains a list of 730 drivers who have recently completed an online driving course and e-mails a questionnaire to a randomly selected group of 200 of these drivers. Only 102 of the questionnaires are returned. Identify the population and the sample in this study. (4 points)
The population is 200 and the sample is 102.
The population is 730 and the sample is 200.
The population is 102 and the sample is 730.
The population is 730 and the sample is 102.
The population is 200 and the sample is 730.
Answer: The population is 730 and the sample is 102.
Step-by-step explanation:
When we have a given set of elements, N elements, the population is N.
And if we do statistics with A of these N elements, the sample is A.
In this case, the population is the set of the 730 drivers, then the population is 730.
And while 200 of them are randomly selected, we can only work with 102 of them (because we have only 102 returned questionnaires).
Then the sample will be 102.
Then the correct option is:
The population is 730 and the sample is 102.
Answer:
730 and 102.
