6.506875 is the answer because 7.25% out of 100 is .0725 and 89.75 times that is 6.506875
Answer:
C
Step-by-step explanation:
B. 24x2 is the correct answer
If we draw a perpendicular line from one of the vertices of the triangle we get 2 right angled triangles each with altitude 9 ins and vertex angle = 30 degrees. So:-
cos 30 = 9 /h where h = one of the sides of the equilateral triangle
h = 9 / cos 30 = 10.392 inches
Therefore the perimeter of the triangle = 3 * 10.392 = 31.1769 ins
Answer is 31.18 inches to the nearest hundredth.
