Answer:
The answer is 1,200 meters
Step-by-step explanation:
So what I did was find the rate so we want to know how much Sheila can do in just 1 minute first so you would have to do 6,000/ 15 which gives you 400 so he does 400 meters in just 1 minute. So then you would have to multiply 400 by 3 which gives you 1,200, making that your answer.
hope that helped!

Answer:
372 m²
Step-by-step explanation:
A vertical line down the center of the figure will divide it into two congruent trapezoids, each with bases 13 and 18, and height 12.
The area of one of them is ...
A = 1/2(b1 +b2)h
So, the area of the two of them together is ...
A = (2)(1/2)(b1 +b2)h = (b1 +b2)h
A = (13 m + 18 m)(12 m) = 372 m²
Answer:
4 cos² 60° + 4 sin² 45° -sin² 30° = 4(1/2)2
Step-by-step explanation:
2 + 4 (1/√2)2 - (√3/2)2 = 1 + 2 - 3/4 = 3 - 3/4 = 9/4.
