The room scale will only fit on an 8 1/2" X 11" page if 1/2 iinch = 1 foot is used. If we take the largest measurement 15 X 20......the 15 would hang over the edge of the paper no matter which way we turn it. With the 1/2" we can get 17 feet on the 8 1/2 side and and 22 on the 11" side.
<span>1 inch = 1 foot is the answer. The</span> appropriate scale to use on an 8 1/2 by 11 sheet of paper for a sketch of the room and carpet is <span>1 inch = 1 foot. The other choices are incorrect because it is not possible for 1/2 inch= 1 foot and it is grammatically wrong when we say 1 inches= 1 foot.</span><span />
<span>Total mass contains 320g copper. How many parts of 16g copper are there of the total mass of 320g copper? 320/16 = 20. There are 20 portions of 16g copper.
(320/16) * 3 = 60g
There are 60g of zinc in the compound.</span>
