You just need to move on the vertical line corresponding to x = 30 students.
Start at the x-axis, for x=30 students, and move vertically upward until you reach the point, then move horizontally to the left, until the y-axis and do your best estimate of the y-coordinate reading.
The value is a little below 180 and quite above 170, then a good approximate is 180. It could also be 179, or 178. Almost sure a number greater than 175.
Answer:
a = 254.5 mm² ( if using accurate value of π)
a = 254.4 mm² (if using 3.14 as approximate value of π)
Step-by-step explanation:
a = πr²
a = π * 9²
a = π * 81
(note using π = 3.1415926536)
a = 254.4690049408
Rounded
a = 254.5 mm²
(a = 254.4 If using π = 3.14)
Answer:
Tad ran 6 miles while Elaine ran 4 miles.
Step-by-step explanation:
Since Tad runs one-half mile for every one-third mile that Elaine runs, to determine, if together they run a total of 10 miles, how far does Tad run, the following calculation must be performed:
0.5 x 2 = 1
0.333 x 2 = 0.666
10 / 1.666 = X
6 = X
6 x 1 = 6
6 x 0.666 = 4
Therefore, Tad ran 6 miles while Elaine ran 4 miles.
To find a missing angle of a quadrilateral first
know what a quadrilateral equals, in this case, it equals 360 degrees
now take
82+114+95= 291
then take
360-291= 69
the 4th angle is 69 degrees
hope this helps!
