An add on from Part A Please i need this done before grades are due!!
The circumference you found in part A is in inches. To convert the circumference to miles, divide the number of inches by 12 to get the circumference in feet. Then divide that number by 5,280 (there are 5,280 feet in a mile) to get the circumference in miles. This number is the number of miles a cup traveled in one revolution. Multiply this value by the number of revolutions the cup made in one minute. Then multiply by 60 minutes to get the approximate number of miles per hour.

Note: This is only an approximate value because it does not take friction into account.

the question isn't complete here so i can't right an answer '_'

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
