Huh?????????????????.....
Answer:
400
Step-by-step explanation:
if the train travel in 150miles in 3hr then\
150/3=50miles a hr
50 x 8 = 400 miles
That would be, with full working out,
1w + 14w, which equals 15w, then you - 6w, which makes 9w
Using the distance formula we can determine the perimeter of PQR.
Distance formula: d=√(x-x1)^2+(y-y1)^2
distance of PR: √(-2+2)^2+(9+3)^2= 12
distance of QR: √(7+2)^2+(-3+3)^2=9
distance of PQ: √(7+2)^2+(-3-9)^2= 15
Perimeter: 12+9+15=36
Answer:
578.3 ft²
Step-by-step explanation:
slope lengths are
L = √(11² + (13/2)²) = √163.25
A = (13 + 2√163.25)(15) = 578.307970...
