Answer:
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.
Answer:
x = (-(10*y+10))/2
Step-by-step explanation:
x in (-oo:+oo)
6*x-((2/3)*(6*x-(15*y))) = -10 // + 10
6*x-((2/3)*(6*x-(15*y)))+10 = 0
(-2/3)*(6*x-15*y)+6*x+10 = 0
6*x-2/3*(6*x-15*y)+10 = 0
6*x-2/3*(6*x-15*y)+10 = 0
2*x+10*y+10 = 0
2*x+10*y+10 = 0
2*x+10*y+10 = 0 // - 10*y+10
2*x = -(10*y+10) // : 2
x = (-(10*y+10))/2
x = (-(10*y+10))/2
Answer:
If the outside diameter of the wheel is 66cm, it will travel 1 wheel circumference. Circumference is Pi x diameter = 3.14 x 66 = 207.24 cm.Step-by-step
Explanation:
If the diameter is of the wheel (without the tire) you need to calculate the actual diameter from the outermost edge of the tire.
So in 30 min will hike 2 1/4 miles =9 of those 1/4 miles therefore in 10 min will hike 9/3 =3 of those 1/4 miles = 3/4 of a mile
3/4 mile in 10 min;
(3/4)• 4 = 3 miles in 40 min;
6 miles in 80 min;
9 miles in 120 min;
12 miles in 160 min;
15 miles in 200 min;
18 miles in 240 min or 4 hours
