The question is incomplete, the complete question is below:
Scientists have found a relationship between the temperature and the height above a distant planet's surface. , given below, is the temperature in Celsius at a height of kilometers above the planet's surface. The relationship is as follows: T(h) = 30.5 -2.5h.
a) Calculate T^-1(x)
b) T^-1(15)
Answer:
a) 
b) 6.2 °C
Step-by-step explanation:
a) 
b) 
Answer:
20 20/27
Step-by-step explanation:
(2 2/3)(3 1/3)(2 1/3) = (8/3)(10/3)(7/3) = 560/27 = 20 20/27
_____
<em>Additional comment</em>
The first two numbers can be written as a difference and a sum:
= (3 -1/3)(3 +1/3)(2 1/3)
= (3·3 -1/3·3 +3·1/3 -1/3·1/3)(2 1/3)
= (9 -1/9)(2 +1/3) = 9·2 +9·1/3 -1/9·2 -1/9·1/3 = 18 +3 -6/27 -1/27
= 20 20/27
28 number of Houses = 40%
of the total houses the cleaning company needs to clean in a week.
Find the total number of houses do the cleaning company needs to clean in
a week>
=> 28 number of houses / 40%
=> 28 / 0.4
=> 70
Thus, the total number of houses that a cleaning company needs to clean in
the whole week is 70 houses.
Since they already cleaned 40% of it, which is 28, thus, they still need
to clean 42 more.
