Answer:
C) 14 cm
Step-by-step explanation:
A triangle solver can quickly show you the third side is 14 cm.
__
The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...
c² = a² +b² -2ab·cos(C)
c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74
c ≈ √196.74 ≈ 14.03
The length of the third side is about 14 cm.
Answer:
D
Step-by-step explanation:
Let x = total games played
16% = 0.16
0.16x = 40. Divide each number by 0.16.
x = 250
Wendy played 250 games
Answer:
288
Step-by-step explanation:
The volume of the cube is 0.5^3 = 0.125, and the volume of the rectangular prism is 4*3*3 = 36.
Now, you just divide 36 by 0.125, which is 288.
I hope this helped.
