Mark earns $135 for selling a $1500 refrigerator. Which sale listed has the same commission rate? $36 commission on a $400 dryer or B) $40 commission on a $500 dryer sale C) $210 commission on $1400 oven sale d) $30 commission on a $600 freezer sale?
salelisted has the same commssion rate. ?
Answer:
Option A is the correct choice.
Step-by-step explanation:
We have been given that Mark earns $135 for selling a $1500 refrigerator.
Since proportions states that two fractions are equal , so we will use proportions to find the same commission rate with the listed price from our given choices.
We can set proportion for commission and listed price as:
[tex]\frac{\text{Commission}}{\text{Listed price}}=\frac{135}{1500}[/tex]
Let us compare our given choices one by one.
A. $36 commission on a $400 dryer.
[tex]\frac{36}{400}=\frac{135}{1500}[/tex]
Upon simplifying our proportion we will get,
[tex]\frac{9}{100}=\frac{9}{100}[/tex]
[tex]0.09=0.09[/tex]
We can see that commission rates for both items are equal, therefore, option A is the correct choice.
B. $40 commission on a $500 dryer sale.
[tex]\frac{40}{500}=\frac{135}{1500}[/tex]
Upon simplifying our proportion we will get,
[tex]\frac{2}{25}=\frac{9}{100}[/tex]
[tex]0.08\neq 0.09[/tex]
We can see that both commission rates are different, therefore, option B is not a correct choice.
C. $210 commission on $1400 oven sale.
[tex]\frac{210}{1400}=\frac{135}{1500}[/tex]
Upon simplifying our proportion we will get,
[tex]\frac{3}{20}=\frac{9}{100}[/tex]
[tex]0.15\neq 0.09[/tex]
Since the commission rates are different, therefore, option C is not a correct choice.
D. $30 commission on a $600 freezer sale.
[tex]\frac{30}{1400}=\frac{135}{1500}[/tex]
Upon simplifying our proportion we will get,
[tex]\frac{3}{140}=\frac{9}{100}[/tex]
[tex]0.0214\neq 0.09[/tex]
Since the commission rates are different, therefore, option D is not a correct choice.

Delta airlines quotes a flight time of 2 hours, 5 minutes for its flights from cincinnati to tampa. suppose we believe that actual flight times are uniformly distributed between 2 hours and 2 hours, 20 minutes.what is the probability that the flight will be no more than 5 minutes late (to 2 decimals)?
The likelihood that the flight will be no more than 5 minutes late would be equal to a flight that arrives between 2 hours and 2 hours and 10 minutes.
So the answer would be:
P (5 late or less) = 10 * 1/20 = 0.5
The answer is 0.5
But if we are looking for the probability of the flight that would be 10 minutes late, the likelihood of that event would be 0.25.
Final answer:
The probability that a Delta airlines flight from Cincinnati to Tampa will be no more than 5 minutes late, given that the actual flight times are uniformly distributed between 2 hours and 2 hours, 20 minutes, is 0.50.
Explanation:
The question deals with the uniform distribution of flight times and calculating the probability that a flight will be no more than 5 minutes late. Assuming flight times are uniformly distributed between 2 hours (120 minutes) and 2 hours, 20 minutes (140 minutes), the total range of flight times is 20 minutes (140 minutes - 120 minutes).
Delta airlines quotes a flight time of 2 hours, 5 minutes, which is 125 minutes. Therefore, a flight being no more than 5 minutes late means the flight time would be at most 130 minutes. To find the probability that the flight time is 130 minutes or less, we calculate the proportion of the distribution that falls within this range.
The probability that the flight will be no more than 5 minutes late is the length of the interval from 120 minutes to 130 minutes divided by the total range (20 minutes), which is (130 - 120) / 20 = 10 / 20 = 0.5. Thus, the probability is 0.50 to two decimal places.
Sam opened a savings account with an initial deposit of $2,000. Since then, he has never made any other deposits or withdrawals. His savings account earns 0.4% interest monthly and an annual bonus of 1.5% interest. Which equation gives the approximate amount, A(x), he has in his savings account as a function of x, the number of years since his initial deposit?
A(x) ≈ 2,000 + (1.059)x3
A(x) ≈ 2,000(1.019)x2
A(x) ≈ 2,000(1.065)x
A(x) ≈ 2,000(1.059)x2
Answer:
Third option:
[tex]A(x)\approx 2,000(1.065)^x[/tex]
Step-by-step explanation:
Notice if we invest 2,000 then the first month then after the first 0.4% interest is earned we will have in the account:
2,000(1+0.004) = 2,000(1.004)
I just applied the simple interest formula.
Then after the second month we will have:
[tex]2,000(1.004)(1.004) = 2,000(1.004)^2[/tex]
And so on each month.
So at the end of the first year (12 months) we have:
[tex]2,000(1.004)^{12}[/tex]
But we also earn an additional 1.5% in the year, so we will have:
[tex]2,000(1.004)^{12}(1.015)[/tex]
At the end of the second year we will have:
[tex]2,000[(1.004)^{12}(1.015)]^2[/tex]
At the end of the third year:
[tex]2,000[(1.004)^{12}(1.015)]^2[/tex]
And so on,
So if the number of years is denoted with x, at the end of x years we will have the following amount in the savings:
[tex]2,000[(1.004)^{12}(1.015)]^x[/tex]
We use our calculator to simplify that inside the brackets:
[tex](1.004)^{12}(1.015)=1.06481[/tex]
Rounding to the third decimal place we get: 1.065
So notice the amount in the savings after x years will be:
[tex]2,000(1.065)^x[/tex]
Since they want it in function notation we just write the A(x) that denotes the amount in the savings:
[tex]A(x)\approx 2,000(1.065)^x[/tex]

Julianna works 32 hours each week. She earns $14.15 an hour. Which is closest to the amount of money Julianna will earn if she works for 46 weeks.(Please show work?)
A) $16,800
B) $18,000
C) $21,000
D) $22,500
Julianna will earn $22,579.20 if she works for 46 weeks, which is closest to the option D) $22,500.
Explanation:To calculate the amount of money Julianna will earn if she works for 46 weeks, we need to multiply the number of work hours per week (32) by the hourly wage ($14.15), and then multiply that result by the number of weeks worked (46). This can be calculated as follows:
Total earnings = (32 hours/week) × ($14.15/hour) × (46 weeks)
Total earnings = $22,579.20
Therefore, the closest amount of money Julianna will earn if she works for 46 weeks is $22,579.20, which is closest to option D) $22,500.

Find the point on the plane 2x+5y+z=8 that is nearest to (2,0,1).
Answer:
(2.2, 0.5, 1.1)
Step-by-step explanation:
The parametric equation of the line normal to the plane and through point (2, 0, 1) can be written ...
... L = (2, 0, 1) + t(2, 5, 1)
We want to find the value of t (and the corresponding point) that makes L satisfy the equation of the plane.

For this value of t, L is ...

Which of the following statements must be true about a rectangle? Choose all answers that apply: Choose all answers that apply: A It has four sides of equal length. B It has four right angles. C It has two pairs of parallel opposite sides.
Answer:
The correct answers are options B and C.
Step-by-step explanation:

C It has two pairs of parallel opposite sides.
All angles are right angles by definition of a rectangle. The rectangle has 2 pairs of parallel opposite sides.
Option A is wrong as its a square whose all 4 sides have equal length.

At an automobile factory, 1849 parts are made in 4 hours. What is the average rate at which parts are made per hour?
Answer:
462.25
Step-by-step explanation:
At an automobile factory, the number of parts are made in 4 hours = 1849.
We have to calculate the average rate of production per hour.
We will divide the production of parts in 4 hours by 4 to get the number of parts made per hour.
The average rate of production in one hour = [tex]\frac{1849}{4}[/tex]
= 462.25/hour
462.25 parts are made per hour.

What are 2 ways three people can share fifths?
Final answer:
Three people can share fifths by dividing one pie into five slices and each taking three, or dividing three pies into fifteen slices and each person getting one slice from each pie. Both methods ensure each person receives three-fifths of a pie.
Explanation:
Two ways that three people can share fifths involve division and allocation of pie (or any other divisible whole). One way is to take a single pie, divide it into five equal slices, and each person takes three slices. However, since we need to divide these among three people and a pie has only five slices, we'll end up with a fraction of a slice per person. The second way is to start with three pies, divide them so that there are a total of fifteen slices (five slices per pie), and then each person gets one slice from each pie, totaling three slices per person.
Here are two arithmetic representations of the scenarios:
First method: (3 slices/person) / 5 slices = 3/5 per personSecond method: 1 slice from each of 3 pies / 5 slices per pie = 3/5 per personWhether we are dealing with one pie or three, each person ends up with the same fraction of the total available pie: three-fifths.
