Given that the garden is rectangular and a line of roses form the diagonal 18.4 m long, we required to calculate the length of the perpendicular side. Here we shall use the Pythagorean theorem. c²=a²+b² where c is the hypotenuse, a and b are the legs. from the information given: c=18.4 m a=13 m plugging this into our expression we get: 18.4²=13²+b² next we solve for the value of b b²=18.4²-13² b²=338.56-169 b²=169.56 b=√169.56 b=13.0215 hence the length to the nearest tenth of a meter will be approximately 13.0 m
It would be 9 because you get half the number of projects because 18 students are partners and if you divide that you would have 9 groups of 2 and if you multiply that by the number of projects you would get the number of projects (ex:18 dividend by 2 it's 9 then if there is three projects assigned you multiply 9 by 3 to get 27 projects got it?
You can make 3 and 3/7 into a improper fraction as 24/7 by multiplying 7 by 3 which is 21 and then adding that to 3 which gives you to answer 24/7. To find the reciprocal you simply flip the fraction which gives you 7/24
