Answer:
12. n = 8
13. t = 308
14. k = 5
Step-by-step explanation:
12. 2/3 = n/12
Multiply by 4 because 3×4 = 12
So, n = 8
13. 33/t = 3/28
Multiply by 11 because 3×11 = 33
So, t = 308
14. k/6 = 15/18
Multiply by 3 because 6×3 = 18
So, 3k = 15. k = 5
Area of the rectangular mat = 12 x 4 = 48 in²
Area of the 3 circles = 3( πr²) = 3(3.14 x 2²) = 37.68 in²
P(landing in a circle) = 37.68/48 = 157/200 = 0.79 (nearest hundredth)
Answer: The probability of landing in one of the circles is 0.79.
Answer:
I think option a is correct answer because consecutive angles are supplementary.
