Option C. It builds up a higher level of oxygen in the blood.

At rest, the heart pumps out about 5,000mL/min of blood. This is called the cardiac output. One can say that, at rest, the total systemic blood flow throughout the body is about 5L/min. At the extreme level of activity the heart pumps much harder and faster and is usually able to quintuple its output to about 25L/min of blood flow. This amount applies to the right side of the heart, which pumps blood to the lungs so it can pick up oxygen and drop off Carbon dioxide, and the left side of the heart that pumps it to the rest of the organs and tissues of the body.

find the area of a rhombus whose side is 7.5 cm and whose altitude is 4 cm if one of its diagonals is 8 cm long find the length
vovikov84 [41]

Answer:

Area = 30 square centimeter

Diagonal = 7.5 centimeter

Explanation:

Area of the rhombus is equal to the product of its side and altitude

Thus,

Area of the rhombus = 7.5 * 4 = 30 square centimeter

Area of the rhombus is equal to half the product value of two diagonal

30 square centimeter = 0.5 * d_1 * d_2\\

d_2 = \frac{30}{0.5*8} \\d_2 = 7.5 cm
