4. Solve the following proportions for x: 6/36 = x/48 9:72 = x:64 %3D 24/144 = 18/x x/27 = 17/81 %3D 5. At rest, the left ventricle of the heart pumps 5,000 mL of blood per minute. Blood flow to the kidneys is approximately 1,200 mL per minute at rest. Assuming that renal blood flow increases in proportion to total blood flow, what will be the blood flow to the kidneys if the heart pumps 7,000 mL/min? Show your work! renal blood flow = 6 An electrocardiogram is recorded on mm-grid chart paper moving at a speed of 25 mm/s. If the recorded distance between heart beats is 20 mm, what is the subject's heart rate in beats per minute? Show your work! heart rate %3D 15
