Answer:
x = 58
Step-by-step explanation:
The angle formed by two secants
= 1/2(difference of intercepted arcs)
51 = 1/2 (160 - x)
Multiply each side by 2
51*2 = 2*1/2 (160-x)
102 = 160-x
Subtract 160 from each side
102-160 = 160-160-x
-58 = -x
Multiply each side by -1
58 =x
I’m not too sure but i think The area of one is 4 inches. There are 8 squares on each side, so when finding the area of the board, you get 64. The checkerboard is 16 inches long, and there are 8 squares, so it is approximately 2 inches long. To find area, you multiply length by width. Since they are squares, it would be 2*2, which leads you to the answer of 4. Hope this helps!
Answer:
Length = 21.3333333333; Width: 12.6666666667
Step-by-step explanation:
Perimeter = 68
Perimeter of a rectangle:
2 (L +W)
Length (L) = 2W - 4
Width = W
2 ( 2W -4 +W) = 68
=> 2 (3W - 4) = 68
=> 6w -8 = 68
=> 6w = 76
=> w = 12.6666666667
Length = (12.6666666667 X 2) - 4
=> 21.3333333333
Answer:
14.4 hours
Step-by-step explanation:
14(2) + 14.1 + 14.2(3) + 14.3(3) + 14.4(2) + 14.5(3) + 14.6(3) + 14.7(2) + 14.9 / 20
= 288/20
= 14.4 hours
