Find the markup and the selling price of the following item. Round answers to the nearest cent.
A skateboard costing $39.00 marked up 40% on cost.
Markup = a. $97.50
b. $15.60
c. $40.00
Selling price = a. $1.00
b. $54.60
c. $79.00
Answer:
Mark up: $15.6 (option b)
Selling Price: $54.6 (option b)
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
A skateboard costing $39.00 marked up 40% on cost.
To calculate the markup we have to multiply the skateboard cost (39) by the percentage in decimal form (40/100= 0.4)
39 x 0.4 =15.6
Mark up: $15.6 (option b)
For the selling price we have to sum the cost and the markup:
15.6 + 39 = 54.6
Selling Price: $54.6 (option b)

The weights of bags of baby carrots are normally distributed, with a mean of 2929 ounces and a standard deviation of 0.330.33 ounce. bags in the upper 4.5% are too heavy and must be repackaged. what is the most a bag of baby carrots can weigh and not need to be repackaged?
A bag of baby carrots can weigh 2929.54 ounces to be not repackaged.
To find the weight threshold for bags of baby carrots that need repackaging, we need to find the weight value corresponding to the 95.5th percentile of the normal distribution. This corresponds to the value that separates the upper 4.5% of the distribution (since 100% - 4.5% = 95.5%).
We can use the z-score formula to find the z-score corresponding to the 95.5th percentile, and then use that z-score to find the corresponding weight value.
The z-score formula is:
z = [tex]\frac{x - \mu}{\sigma}[/tex]
where:
x - value we're interested in (weight threshold)
[tex]\mu[/tex] - mean of the distribution = 2929
σ - standard deviation of the distribution = 0.33
z - z-score corresponding to the percentile
First, let's find the z-score corresponding to the 95.5th percentile using a standard normal distribution table or a calculator. For a normal distribution, the z-score corresponding to the 95.5th percentile is approximately 1.645.
Now, we can rearrange the z-score formula to solve for x:
x = [tex]\mu[/tex] + z σ
Plugging in the values:
x = 2929 + 1.645 × 0.33
x = 2929 + 0.54285
x = 2929.54
Therefore, the most a bag of baby carrots can weigh and not need to be repackaged is approximately 2929.54 ounces.
The question is:
The weights of bags of baby carrots are normally distributed, with a mean of 2929 ounces and a standard deviation of 0.33 ounces. The bags in the upper 4.5% are too heavy and must be repackaged. What is the most a bag of baby carrots can weigh and not need to be repackaged?

Leila makes 9 dollars for each hour of work. write an equation to represent her total pay p after working h hours
Final answer:
Leila's total pay after working a certain number of hours is found by the equation p = 9h, where p represents the total pay and h represents the hours worked.
Explanation:
Leila's total pay p after working h hours at a rate of $9 per hour can be represented by the equation p = 9h. This equation indicates that for every hour Leila works, she earns $9. Therefore, to find her total pay, you would multiply the number of hours she has worked (h) by her hourly wage ($9).

The two figures above are regular. If s and t represent the lengths of the segments indicated in the figures, which statement is true? A. s > t B. t > s C. s = t D. No comparison can be made.
Without the necessary figures or context, we cannot make a correct comparison between segment lengths s and t. The question lacks clarity and detail, therefore the answer is that no comparison can be made.
Explanation:The geometrical figures and the comparison of segment lengths within these figures. Given the Pythagorean theorem and the details about forces and lines, we have information that could pertain to geometry, specifically to properties of triangles and the comparison of segment lengths or areas. However, without the actual figures or a clear indication of the context involving s and t, we cannot provide an accurate comparison between them. This implies that the answer would be D. No comparison can be made.
It is possible that s and t are referring to the lengths of sides in a triangle, but this question, as presented, lacks the clarity and detail required to make a precise calculation or comparison. For example, in the case of two segments being hypotenuse and side of right triangles, if we knew the lengths of the other sides, we could apply the Pythagorean theorem to find the relationship between s and t. But without this information or a clear diagram, we cannot conclude anything about the relationship between s and t.

A clock gains 0.020 s/min. how many seconds will the clock gain in exactly six months, assuming 30 days are in each month
Final answer:
To calculate the total seconds a clock gains in six months, we multiply the number of minutes in six months by the gain per minute, resulting in a total of 5,184 seconds gained.
Explanation:
The question asks us to determine how many seconds a clock gains over a six-month period, assuming each month has 30 days. The clock gains 0.020 seconds per minute.
To find the total seconds gained, we need to calculate the number of minutes in six months and then multiply that by the gain per minute. There are 60 minutes in an hour, 24 hours in a day, and the problem assumes 30 days in a month. Over six months, this totals:
60 minutes/hour × 24 hours/day × 30 days/month × 6 months = 259,200 minutesNow, multiply the total minutes by the gain per minute:
259,200 minutes × 0.020 seconds/minute = 5,184 secondsTherefore, the clock will gain a total of 5,184 seconds over a six-month period assuming each month has 30 days.
