Answer:
A n C={0,2}
Step-by-step explanation:
From the question,
A={0,1,2,3}
B={a,b,c,d}
C={0,a,2,b}
A n C means A intersection C; and by definition all the members that are common to both set A and C
Hence A n C={0,2}
Answer:
20,000m²
Step-by-step explanation:
If they jog 12 km/h for half an hour, they have covered.
12 X 0.5 = 6km in 10 circuits. Making 1 perimeter
6 / 10 =0.6 km (600 m).
To determine area we need to convert this perimeter to length and width. We know that it is a rectangle, with 2 equal widths and 2 equal lengths, and the length is twice the width.
So L = 2W
Perimeter = 2W + 2L
600 m = 2W + 2(2W)
600 m = 6W
W = 100 m
L = 200 m
Area = 100 X 200 = 20,000 m²
50 miles. 15 is to 30 as 50 is to 100.
