B is one of them, i'm not sure how any of the other answers are equivalent to 20% of 45 which is 8.
triangle on right is the same as the triangle on the left
use pythagorean theorem
hypotenuse will give to the sides of the rectangle
a^2 + b^2 = hypotenuse squared
10.4^2 = 108.16
15.3^2 = 234.09
342.25 = hypotenuse squared
take the square root in both sides
hypotenuse = the square root of 342.25 =
18.5
add up the areas of the 2 triangles and rectangle
triangle area is 1/2 times 10.4 times 15.3 =
79.56
2 triangles areas are 159.12
rectangle area is 18.5 × 7 = 129.5
159.12 + 129.5 = 288.62
answer 1 = 288.62
second question:
to get 1 side take the
square root of 702.25 which is
26.5
to get the perimeter
multiply 26.5 by 4 which is
106
answer 2 is choice B 106
Answer:
A) A graphic rating scale- a scale where the participant places his or her response along a line or continuum; the score or measurement is its distance in millimeters from either endpoint.
B) A multiple rating list- a single interval or ordinal numerical scale where raters respond to a series of objects; results facilitate visualization.I will recommend a multiple rating list, because it is an easier process to conduct in a employee environment.
