Find the area of the parallelogram.
A parallelogram has a lower side measuring 24 centimeters and a right side measuring 9 centimeters. A dashed vertical segment with endpoints on the upper and lower sides is 8 centimeters and meets the lower left vertex at a right angle.
The area of a parallelogram is given by the formula: A = base * height.
In this case, the base of the parallelogram is the lower side measuring 24 centimeters.
To find the height, we need to use the dashed vertical segment. Since it is perpendicular to the lower side and meets the lower left vertex at a right angle, it is the height of the parallelogram.
The height is given as 8 centimeters.
Therefore, the area of the parallelogram is: A = 24 cm * 8 cm = 192 cm².
find the mean 12,8,7,10,8,8,10
To find the mean, we need to sum up all the numbers and then divide by the total number of values.
The given numbers are: 12, 8, 7, 10, 8, 8, 10.
Sum of the numbers = 12 + 8 + 7 + 10 + 8 + 8 + 10 = 63.
Total number of values = 7.
Mean = Sum of the numbers / Total number of values = 63 / 7 = 9.
Therefore, the mean of the given numbers is 9.
28,20,30,,25 what is the mean of the number of student in a class
To find the mean, we need to sum up all the numbers and then divide by the total number of values.
The given numbers are: 28, 20, 30, 25.
Sum of the numbers = 28 + 20 + 30 + 25 = 103.
Total number of values = 4.
Mean = Sum of the numbers / Total number of values = 103 / 4 = 25.75.
Therefore, the mean of the number of students in a class is 25.75.
12,50,48 what is the fourth number
To find the fourth number, we would need additional information or a pattern to determine the next number in the sequence. Without any additional information or pattern, it is impossible to determine the fourth number.
the mean of four number is 30.12,50,48 what is the fourth number
To find the fourth number when the mean of four numbers is given, we can use the formula for the mean:
Mean = Sum of the numbers / Total number of values
The given mean is 30.12.
The sum of the numbers is therefore: 30.12 * 4 = 120.48
The sum of the given three numbers (50 + 48 = 98) is 98.
To find the fourth number, we subtract the sum of the given three numbers from the sum of all four numbers:
Fourth number = 120.48 - 98 = 22.48
Therefore, the fourth number is 22.48.
