The distance should be .625 of an inch. You get this by diving 11.25 by 18.
P=2w+2l
74=2(16)+2l
74=32+2l
42=2l
21=l
The length is 21 mm.
The answer is n-9=27, I am 100% confident in my answer...hope you get a nice grade :)
Answer:
312
Step-by-step explanation:
Since the ratio is 7:8, mark it as 7x:8x.
Now, they said that the first length is 273. Solve the equation:
7x=273
x=39
Substitute it into 8x. 39*8=312. That's your answer.
PLS MARK BRANILIEST!!!
