1.BD=AC
AC^2=(9^2)+(6^2)-2(9)(6)COS115
AC^2=117-108COS115
AC=√71.358
AC=8.447//
Answer: 539 without defects
Step-by-step explanation: Im pretty sure we have to turn 12/320 into a percent, which is 0.0375, or 3.75%
So with that information, we need to find 3.75% of 560.
do 0.0375 x 560, which is 21.
21 are defects, so do 560 - 21 is 539.
1 g/ml is 8.3454 lbs/gal. So you multiply 1.09 into 8.3454 and your answer is 9.1 lbs/gal
It is the square root of 155^2-124^2 according to Pythagorean's theorem, which is equal to 97, so it is B.
