Answer:
line up the decimal points first and then compare values, starting with the ones places, then compare the tenths place, then the hundredths, etc.
0.210 - this is 21/100
1.320 - this is 1 32/100
2.100 - this is 2 1/10
0.021 - this is 21/1000
Step-by-step explanation:
smallest is 0.021
0.210
1.32
largest is 2.1
Answer:
550.2cm
Step-by-step explanation:
6 cm x 7 cm x 13.1 cm = 550.2 cm
Are you asking about the sigma sign used for sequence additions?
Answer:
I think it is Table D
Step-by-step explanation:
Hmmmm judging by the values in between integers, like 2.5, 1.5, -2.5, -3.5 and so on, those values always produce a smaller number hmm that sounds whack... lemme put it differently.
a floor() function, namely ⌊x⌋ like that, will floor the decimal values, so ⌊2.5⌋ floors to 2, because 2.5 is between 2 and 3, and the smallest is 2, the "floor", the 3 will be the "ceiling".
so for a floor function, ⌊1.5⌋ is 1, 1.5 is between 1 and 2, 1 is the smallest, ⌊-3.5⌋ is -4, recall that on the negative side, the closer to 0, the larger, so -1 is much larger than -1000.
and say ⌊-1.35⌋ is -2, -1.35 is between -2 an -1 and -2 is the smallest, the "floor".
that said
x = 2.5 ⌊ 2.5 + 3⌋ is ⌊5.5⌋ which is 5
x = 1.5 ⌊ 1.5 + 3 ⌋ is ⌊4.5⌋ which is 4
x = -2.749 ⌊ -2.749 + 3⌋ is ⌊0.251⌋ which is 0
anyway and so on, so you can pretty much see is the floor function of ⌊ x + 3⌋.
