the answer to your question is 13 mm
actually i still think its the second answer
The diagonals bisect each other at their midpoints.
Find the midpoint of diagonal WY :-
= (-1+6/,2 , (7-2)/2
= (2.5, 2.5) answer
Its C
If it doesn't mean options as an added cost, it would be a total of $34,765.
If it means options as an added cost it would total to $35,140
Answer:
(a) b = (4/7)c
(b) Bill: 40 shingles/hour; Chip: 70 shingles/hour
Step-by-step explanation:
Let b and c represent Bill's and Chip's rates in shingles per hour, respectively. Then we have ...
7b = 4c
c - b = 30 . . . . shingles per hour difference in rates
(a) Bill's rate in terms of Chip's rate can be found by dividing the first equation by 7
b = (4/7)c . . . . . Bill's rate is 4/7 of Chip's rate
__
(b) To find the rates, we can multiply the second equation by 7 and substitute using the first equation:
7c -7b = 210
7c -4c = 210
c = 210/3 = 70
b = (4/7)(70) = 40
Bill's rate is 40 shingles per hour; Chip's rate is 70 shingles per hour.
