Answer:
700π m ~ 2199 m
Step-by-step explanation:
diameter = d = 200 m
2 min 20s = 140 s
1 round / 40 s
140 = 40 * 3 + 20
so the athlete will cover 3 round and half
1 round = d * π
covered = c = 3 * 200 * π + 200/2 * π = 700 * π
Divided 1029.6 with 2,3,5,7, any number
Answer:

is the fraction of sensors upgraded per unit.
Step-by-step explanation:
We are given the following in the question:
Let x be the number of upgraded sensors in one unit and y be the number of non-upgraded sensors in one unit.
Number of modular units = 30
Since some part of unit is upgraded and some are non-upgraded, then, we can write the equation:

Number of non-upgraded sensors =

Thus, we can write the equation:

Fraction of sensors upgraded per unit =

Answer:
All are rational numbers.
Step-by-step explanation:
A rational number can be written in the form:

where a and b are integers and b≠0.
We can rewrite 136 as

hence 136 is a rational number.
715-245=470....is an integer and hence a rational number.
(47)(217)=10199....which is an integer, and all integers are rational numbers.

15 is also an integer and hence an integer.
