We can't tell from the information you've given.
With the dots at the end, you showed that there's more
to the decimal. But you didn't say how much more.
-- If the decimal EVER ends, even after a billion places,
then it's rational.
-- If it repeats, then it's rational. That .80012569923 may repeat,
or part of it, like the 9923, may repeat, or the whole thing may be
part of some larger bunch that repeats. We don't know.
An Ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.
Answer:
1. yes 2. no
Step-by-step explanation:
Answer:
a) 86,314.
b) 9,162,500.
Step-by-step explanation:
(a) 838(100 + 3)
= 83800 + 2514
= 86314.
(b) 91625 x 179 - 91625 x 79
= 91625(179 - 79)
= 91625 x 100
= 9162500.
