Answer:
18 Outcomes
Step-by-step explanation:
Each time you flip the coin it has 2 outcomes (Heads or Tails) . Each time you pick a number it has 9 outcomes (1,2,3,4,5,6,7,8,9). So it is asking if you flipped a coin and picked a random number (1-9) at the same time, for whatever reason, you would have 18 outcomes. This is because for every number (1-9) you pick it has 2 different sides of the coin it could land on and vive-versa. Basically, for every coin side there are nine numbers and for every number there are 2 sides.
Answer:
11) A=84.7m²
12) A=75.2km²
13) A=28.05ft²
14) A=48yd²
Step-by-step Explanation:
11) A = 1/2(bh)
A = 1/2(14×12.1)
A = 1/2(169.4)
A = 84.7m²
12) A = 1/2(bh)
A = 1/2(16×9.4)
A = 1/2(150.4)
A = 75.2km²
13) A = 1/2(bh)
A = 1/2(5.1×11)
A = 1/2(56.1)
A= 28.05ft²
14) A = 1/2(bh)
A = 1/2(16x6)
A = 1/2(96)
A = 48yd²
Answer: 11.2 because I know trust me. I did a worksheet with this same question and got 11.2 and it was correct.
3x-2 = 3x+4x+28x
3x-2 = 7x + 28
A they are at 90° angles and that is the definition of being perpendicular.
