Answer:
Step-by-step explanation:
Cross multiplication can be used but not in the beginning. First x should be isolated.

Now subtract
from both sides

In this stage, cross multiplication can be used.

11 is the expected value of the escaped time.
Bv (Bt - Bo0 + (Bt - Bs0
= 4 - 0 + 4+3 = 11
Escape time refers to the time available (and necessary) for a person to escape from a particularly dangerous situation.
Escape time refers to the time available (and required) for a person to escape from a particularly hazardous situation. Understanding escape times is an important part of the hazard assessment process and is a particularly important component of any hazard assessment involving fire, explosion, or potential exposure to toxic substances.
The escape time concept is not simply a function of the time it takes for workers to escape the hazard. It also takes into account and constrains the amount of time workers have to escape before being overwhelmed by the danger. This means that two of her workers trying to escape the same fire may have different escape times if one is wearing a fire suit and the other is not.

Answer:
B
Step-by-step explanation:
The square root of 72 is 8.48528137424 therefore it is more than 8 and less than 9
True! The slopes are opposite reciprocals (aka perpendicular lines)
D because if you multiply y 8 times it will no longer be doubling the area
