ART Contractors must locate an equipment staging area to serve three construction sites, located at (x, y) coordinates (0,3), (1,4) and (5,5). Traffic between the staging area and each of the sites is 30 trips a week, except for the site located at (5,5), which is only 15 trips a week. What is the best set of co-ordinates for the equipment staging area

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

10000

step-by-step explanation: divide by 2,

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
