O = x, h=15 angle = 23
sin 23 = o/h
sin 23 x 15 = x
x=5.9 --> C
Step-by-step explanation:
the next ones are 2, -2, -6,-10,-14,-18 and so on
The sand makes up a rectangular prism of dimensions 8' by 10' by 0.5'.
The volume of sand is then V = L*W*H, or V = (10')(8')(0.5') = 40 cubic ft.

Answer:
x = 6, y = -2
Step-by-step explanation:
24/4 = 6
x = 6
= (5x6)+8y=14
= 8y = 14 -30
8y = -16
y = -16/8
y = -2
Check: 5x6+8x-2= 14
