Answer:
1/4
Step-by-step explanation:
8 blue chips 9 pink chips 1 white chip = 18 chips
P( pink) = pink/total = 9/18 = 1/2
Replace
8 blue chips 9 pink chips 1 white chip = 18 chips
P( pink) = pink/total = 9/18 = 1/2
P(pink, replace, pink) = 1/2 * 1/2 = 1/4
Answer: the answer is b but make sure

Answer:
Step-by-step explanation:
Area of triangle = 1/2 * base * height
Use the side of length 5.6cm as base, the height will be a perpendicular line from the base to the tip of the triangle.
From the right-angle triangle formed by the height and the side of length 3.9cm,
sin(56°45') = height / 3.9
height = 3.9*sin(56°45')
Substituting back into the area equation:
Area = 1/2*5.6*3.9*sin(56°45')
= 9.0cm^2
= 9cm^2
