Answer:
C = 40 degree
AB = 5.785 = 55.79, = 5.8 = 6 (4,3,2,1 significant figures)
BC = 11.748 = 11.75 = 11.7=12 (4,3,2,1 significant figures
Step-by-step explanation:
ASA Angle Side Angle (given)
90-50=40 degree as all angles within triangle add up to 180 degree
C = 40 degree
AC (given = 9
AB = A/H = 9xcos(50) = 5.8 measure
BC = O/H = 9 / sin (50) = 11.7 measure
Volume of cube:
V=x^3 (x=edge)
V=2.5^3
V=15.63 (rounded to nearest hundredth)
3/10 = 30%
30% of students bring their lunch.
Step - by - step - explanation
So first find out the pattern. As you can see it just minuses 2 each time. So first
18, 16, 14, 12 (then minus another 2) equals 10, 8, 6, 4, 2.
So 2 is the ninth of the pattern, so 2 will be your answer.
Hope this helps.
I think the answer is 240
