Answer:
50%
Step-by-step explanation:
He sold it for Rs 15 each. What is his profit percent? CP of 1 pen = 120/12= 10 SP of 1 pen = 15 Profit = 5 P % = (p/CP)*100=(5/10) x 100 = 50%.
Answer:
D. 24
Step-by-step explanation:
The 5-number summary of a data set includes ...
- minimum
- 1st quartile
- median (2nd quartile)
- 3rd quartile
- maximum
<h3>Summary values</h3>
When the data are written in increasing order, they are ...
23 23 24 27 27 28 30 30 30 33 34 35
The minimum is the first value on the list, 23.
The first quartile is the average of the two middle values in the lower half of the data set: (24+27)/2 = 25.5.
The median is the average of the two middle values: (28+30)/2 = 29.
The third quartile is the average of the two middle values in the upper half of the data set: (30+33)/2 = 31.5.
The maximum is the last value on the list: 35.
<h3>Answer choices</h3>
A. 29 is the median
B. 23 is the minimum
C. 31.5 is the 3rd quartile
D. 24 is not part of the 5-number summary
Answer: OPTION D.
Step-by-step explanation:
Given the equilateral triangle shown in the figure, you need to find the value of the altitude "a".
In order to find the altitude, you can use the following Trigonometric Identity:
In this case you can identify that:
Therefore, you can substitute values into :
Finally, you must solve for the altitude "a". Then, this is:
Notice that this result matches with the value shown in Option D.
Answer:
5.655 m³/min
Step-by-step explanation:
Halfway from the bottom of the tank, the radius is half that at the top, so is 1 m. That means the surface area of the water at that point is ...
A = πr² = π(1 m)² = π m²
The rate of flow of water into the tank is the product of this area and the rate of change of depth:
flow rate = area × (depth rate of change)
= (π m²) × (1.8 m/min) = 1.8π m³/min
flow rate ≈ 5.655 m³/min
