Here is a sketch of a Pratt truss, patented in 1844 by two Boston railway engineers, Caleb Pratt and his son Thomas Willis Pratt. Name two triangles from the Pratt truss in the illustration that you would expect to be congruent. This question is by a pex, by the way if someone answers with 'answer is in the link below' do not click it

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
