() is for < and >
[] is for ≤ and ≥
(a,b) means from a to b, not including a or b
(a,b] means from a to b, not including a, but including b
so
x<-3
so from -3 to less of that or
from -∞ to -3
you can't equal -∞, so we use parnthasees
also, it is < so we use parnthaees
(-∞,-3)

Answer:
The revenue for 105 units will be <u>5985 thousand dollars.</u>
Step-by-step explanation:
Given:
The number of units is represented as 'u' and the revenue in thousands is represented as 'R'.
Let us find the ratio 'R' and 'u' and check the type of relationship.
Therefore, the ratio is a constant. Hence, the relationship is a proportional relationship.
A proportional relationship is given as:
Where, 'k' is the constant of proportionality and is equal to the ratio of any two values of 'R' and 'n'.
Therefore,
So, the relationship is
Now, we are asked to determine 'R' when . Plug in 105 for 'n' in the above relationship and find 'R'. This gives,
Therefore, the revenue for 105 units will be 5985 thousand dollars.
Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi = half of the fence
pragnesh and roghui =
qazi and roghui = quarter of the fence
time taken when they all work together
= + +
=
=
= 0.9231 × 60(mins)
= 55.4 mins
