Answer:
Step-by-step explanation:
coordinates of A,B,C are A(5,15),B(15,5),C(20,10)
AB=√((15-5)²+(5-15)²)=√(100+100)=√200=10√2
BC=√((20-15)²+(10-5)²)=√(25+25)=√50=5√2
AC=√((20-5)²+(10-15)²)=√(225+25)=√250=5√10
Perimeter=10√2+5√2+5√10=15√2+5√10≈37 units
To find this out, turn the percent into a decimal:
45% -----> .45 (Divide by 100)
Then multiply the total minutes by the decimal percent:
1400 x .45 = 630
The final answer is, Maris has used 630 minutes.
Hope this helps!
