The function c(t) below relates outside temperature in degrees fahrenheit to the number of cricket chirps per minute.
it takes as input the temperature in degrees fahrenheit, and returns as output the number of cricket chirps per minute occurring at that time.

c(t) = 5t - 200

which equation below represents the inverse function t(c), which takes the cricket chirps per minute as input and returns as output the temperature in degrees fahrenheit?
a) t(c) = (c+5) / 200
b) t(c) = (c-5) / 200
c) t(c) = (c-200) / 5
d) t(c) = (c+200) / 5

d)

Step-by-step explanation:

Given: The function C(t) relates outside temperature in degrees Fahrenheit to the number of cricket chirps per minute.

To find the inverse function of C(t) [named as T(c), rewrite the above equation as

Now, replace 't' by T(c), we get

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
