Slope of perpendicular is -1/3.
Then equation is
y-5=(-1/3)(x+9)
We know that, 1 litre = 1000 ml
Then, 2 litres = 2000 ml
Hence, the required ratio of 1000 ml to 2000 ml be
= 1000 : 2000
= 1 : 2
First find the value of h, or the height using the pythagorean theorem.
13^2=15^2+h^2
289=225+h^2
h^2=64
h=8
Then use the formula bh/2 to find area of the triangle.
10*8/2=40
Final answer: A
Answer:
Gas exchange takes place in the millions of alveolar in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveolar to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveolar.
