Answer:
D. (4, -6)
Step-by-step explanation:
Since the heights of both triangles are the same (CD), their areas are proportional to their bases. That is ...
AC : CB = 3 : 4
In terms of coordinates, ...
4(C -A) = 3(B -C) . . . . multiply the ratios by 4(CB)
4C -4A = 3B -3C . . . .simplify
7C = 4A +3B . . . . . . . isolate C
C = (4A +3B)/7 . . . . . divide by 7
C = (4(1, -9) +3(8, -2))/7 = (28, -42)/7 . . . . substitute given coordinates
C = (4, -6)
15 17/19
6+9 = 16
7/19 + 10/19 = 17/19
25%... so yea it's just 25/100 that's 1/4 which is 25%
Answer:
45 oz
Step-by-step explanation:
1.5 lb = 24 oz
3/4 = 12 oz
24+12+9 = 45 oz
$145
to find the average divide earnings by 5
$725 ÷ 5 = $145
