Answer:
Blue = 116 m^2
Step-by-step explanation:
The area of the path and the square = 30*30 = 900 m^2
The size of the square = 30 - 2 = 28. The square = 28^2 = 784
The path takes up the difference between the two 900 - 784 = 116
Answer:
X=132-13A/A, A cannot equal 0
A=132/X+13, X cannot equal -13
Answer:
1 min : 12 min
Step-by-step explanation:
To simplify the given ratio, convert both to the same unit of time.
1 hour = 60 minutes
3 hours = 3 x 60 minutes
= 180 minutes
So that,
15 min : 3 hours = 15 min : 180 min
divide through by 15 to have;
15 min : 180 min = 1 min : 12 min
Thus the simplified form of the number give is 1 min : 12 min.
Answer:
