In order to find out, you need to square 45 and see weather it is equal to 40^2+30^2
in the end , 1600 won't be equal to 2500 so it won't form a right triangle.
Answer:
31.6% decrease
Step-by-step explanation:
percent of change = difference between original and new values divided by the original value
n = % change
n = 0.72/2.28
n = .3157
n = 31.6%
The given values of this
problem are:
Length = 19. 5 cm
Width (diameter) = 0.6 cm
The unknown is: how much
square cm of plastic are used in one straw? In other words the area of the
straw.
Derivations and solutions:
Area = length x width
Area = 19. 5 cm x 0.6 cm
Area = 11.7 cm(squared) / 11.7
cm^2
10 + 4 + 0.7 + /10
fourteen and seven-tenths
14 7/10
