Answer:
15 total students
Step-by-step explanation:
Based on the line plot picture that is attached below it can be calculated that a total of 15 students spent 5 or more hours last week reading. This can be easily calculated by adding all the x's on the marks of 5 hours or more. With both the boys and girl students combined the tally was the following
5 hours : 4 students
6 hours : 1 student
7 hours : 3 students
8 hours : 3 students
9 hours : 0 students
10 hours: 2 students
11 hours : 2 students
12 hours : 0 students
adding up to 15 total students
Answer:
A = (1/2)Cr . . . or . . . A = C^2/(4π)
Step-by-step explanation:
The diagram shows the area of the circle being redrawn as a parallelogram with the length of it being half the circumference and the height of it being the radius of the circle.
The area of the parallelogram is the product of its length (C/2) and its height (r), so you can compute ...
A = (1/2)Cr
___
Given only the circumference, C = 2πr, you can find the value of r by dividing by its coefficient:
C/(2π) = r
Using this in the above formula, the area can be found from the circumference only as ...
A = (1/2)C·(C/(2π))
A = C^2/(4π)
Answer:
x ≈ 7.9 ft
Step-by-step explanation:
cos∅ = adjacent over hypotenuse
Since we are dealing with a right triangle, we can use trigonometry to help us solve for missing values:
cos44° = x/11
11cos44° = x
x = 7.91274
x ≈ 7.9 ft
Answer:
not correct
tan 60 = x / 2
square root(3) = x / 2
x = 2 * Square root(3)
= Square root ( 4 * 3) = Square root (12)
