Answer:
about 0.0927 seconds
Step-by-step explanation:
Put the given information into the given formula and solve for the remaining variable. It is a linear equation, solved in the usual way.
ln(0.430/0.750) = -7.50t/1.25 . . . substitute the given information
-ln(43/75)/6 = t ≈ 0.092714 . . . . . divide by the coefficient of t
Rounded to 3 significant figures, the time is 0.0927 seconds.
Answer:
all work is shown and pictured
Answer:
an obtuse triangle im pretty sure
The ratio of cos S in triangle RQS is 48 / 73
<h3 /><h3>Right angle triangle:</h3>
- It has one angle as 90 degree
- The sides can be found using Pythagoras theorem
∠Q = 90 degrees
Therefore, Finding cos S,
opposite side = RQ = 55
Hypotenuse = RS = 73
Adjacent side = QS = 48
Therefore,
cos S = adjacent / hypotenuse
cos S = 48 / 73

The equation can be used to find the time in hours, 
and the time will be 2.5 hours. So the correct answer is option A.
<h3>What is an equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Layna can paint a 350-square-foot room in 4 hours.It takes Bebe 7 hours to paint the same room.
Let t be the total time taken by both to paint.They are completing 1 job so the equation will be :
Further solving it we get;
7 t + 4 t = 28
11t = 28
t = 2.5 hours.
Therefore the equation can be used to find the time in hours, and the time will be 2.5 hours. So the correct answer is option A.
