Answer:
RS is about 18.615
Step-by-step explanation:
since XY is the midsegment, it is parallel to the other 2 lines. That also makes the lines proportional
![\frac{22}{26} =\frac{x}{22}](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7B26%7D%20%3D%5Cfrac%7Bx%7D%7B22%7D)
cross multiple
484=26x
x= 18.615
width of teacher's desk is 30 inches
Since the desks are similar then the ratios of corresponding sides are equal
let the width of teacher's desk be w, then
=
( cross- multiply )
30w = 900 ( divide both sides by 30 )
w = 30
There is a square and a half circle.
To find the radius of the circle: 18in - 12in = 6in
Area of a circle = (pi)r^2 = 3.14 (6in)^2 = 3.14 (36in^2) = 113.04in^2
This is an half circle, so we have to divide by 2 the result
56.52in^2 in what we’re looking for.
Area of the square = (12in)^2 = 144in^2
Total area = (144 + 56.52)in^2 = 200.52in^2
Or 201in^2 to the nearest whole number.
Answer:
Interval scale
Step-by-step explanation:
In statistics, there are 4 types of measurement scales namely;
Nominal scales, interval scales, Ordinal scales and Ratio scales.
Now, in this question Cassidy is trying to research the impacts of eating breakfast on college students who have classes prior to 9 am.
This has to do with order as it deals with people who have breakfast before 9 a.m. It also deals with the exact differences in the various answers on the scale of 1 - 10 for each student student in the research for the 20 questions.
This is exactly what the interval measurement scale is all about interval scale deals with order and exact differences in values.
Thus, the scale used is an interval scale.
