She would give 54 to her friends and keep 18 for herself
Answer:
2856m²
Step-by-step explanation:
the square area:
42m × 42m = 1764m²
the triangle area:
42m × 26m = 1092m²
the whole area of the park:
1764m² + 1092m²= 2856m²
Answer: 200
Step-by-step explanation: You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation
170^2 + 150^2 = c^2
28900 + 22500 = c^2
51400 = c^2
√51400 = √c^2
~226 = c
They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.
To the nearest whole number would be 7
