how many liters of water does a pipe with a diameter of 10cm left out, if water flows at the rate of 1.5m / sec and 3 minutes have passed?
Answers
Step-by-step explanation:
To find out how many liters of water flows through a pipe with a diameter of 10 cm when water flows at the rate of 1.5 m/s and 3 minutes have passed, you need to follow the steps below:
Step 1: Find the area of the pipe.
Area = πr² = π(5cm)² = 78.54 cm².Step 2: Convert the flow rate into cm³/s.
Flow rate = 1.5 m/s = 150 cm/s
Volume = Area × velocity = 78.54 × 150 = 11781 cm³/s.Step 3: Find the volume of water that flows through the pipe in 3 minutes.
Time = 3 minutes = 180 seconds
Volume = Flow rate × time = 11781 × 180 = 2,120,580 cm³.Step 4: Convert the volume into liters.
1 liter = 1000 cm³
Volume in liters = 2,120,580 cm³ ÷ 1000 = 2120.58 liters.Therefore, approximately 2120.58 liters of water flow through the pipe with a diameter of 10 cm when water flows at the rate of 1.5 m/s and 3 minutes have passed.

Answer:
(8) B. 5
(9) A. 23
(10) B. 85
Step-by-step explanation:
(8) The mean is the average of all the data and we calculate it by dividing the sum of the data points by the total number of data points.
Since there are 11 numbers in this first problem, we have:
\(Mean=\frac{5+6+4+2+2+0+9+9+12+4+2}{11}\\Mean= \frac{55}{11}\\ Mean =5\)
(9) The mode is the number(s) that occurs most frequently.
23 is the most frequent data point in this data set so it is the mode.
(10) The median is the middle number of the data points. We find it by first arranging the data from least to greatest and then finding the middle value.
If we arrange the data from least to greatest, we get
77, 82, 82, 82, 88, 90, 90, 95.
If we were to keep crossing out the data until we get to middle value, we see that both 82 and 88 lie in the middle (there are exactly 3 values to left and right of both of these values).
Thus, we find the median by averaging these values:
\(Median=\frac{82+88}{2}\\ Median=\frac{170}{2}\\ Median=85\)
Answer:
Step-by-step explanation:
Mean is the average of all of the numbers. Median is the middle number, when in order. Mode is the most common number.
8. Mean = (5+6+4+2+2+0+9+9+12+4+2) / 11 = 55/11 = 5
9. 16 23 22 22 23 23 18 Mode = 22 (middle number)

To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.
For example, after 1 week, we have:
r = 25 + w = 25 + 1 = 26
So there are 26 rabbits after 1 week.
Similarly, after 8 weeks:
r = 25 + w = 25 + 8 = 33
So there are 33 rabbits after 8 weeks.

A bakery sold 36 brownies in a day, which was 30% of the total items sold that day. What was the total number of items the bakery sold that day?
(show work please)
Answers
Answer: The answer is 120
Step-by-step explanation:
We know that 36 is 30% of total items
So our equation would be 36/? = 30/100
From there we cross multiply so 36x100 = 3600
From there, we divide 3600 by 100
Therefore, your answer is 120

The volume of the cylinder is 62.83 cubic cm and the volume of. the cone is 20.94 cubic cm.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
We know that,
It should be noted the to calculate the volume of a cylinder, we can use the formula V = πr²h, where r is the radius and h is the height. In this case, the height and radius of the cylinder and cone are the same.
For the cylinder:
Volume = π(2cm)²(5cm)
V = 20π
For the cone, we can use the formula
V = (1/3)πr²h:
V = (1/3)π(2cm)²(5cm)
V = 20/3π cubic cm (exact value)
Hence, to get an approximate decimal value, we can use a calculator to evaluate:
Volume of cylinder ≈ 62.83 cubic cm
Volume of cone ≈ 20.94 cubic cm
