Answer:
About 0.41 hours
Step-by-step explanation:
THe distance between Michael and Clara is 44 km.
We know D = RT,
Where
D is distance
R is rate (speed)
T is time
For Michael, we can write:
D = 47t
For Clara, we can write:
D = 61t
If we let michael's distance be x, Clara's distance would be 44 - x
So, we can say:
x = 47t
and
44 - x = 61t
Putting first equation into 2nd, we get:
44 - 47t = 61t
SOlving:
44 - 47t = 61t
44 = 61t + 47t
44 = 108t
t = 44/108 = 0.41 hours
The commute took 0.41 hours

Step-by-step explanation:
The easiest way to find the inverse of a function is to swap the x and y, meaning:
We have the function
. Let's call our outputs "y", so we have
. To find the inverse, we're going to change the x and the y's position in the equation, so we have
. Then all we need to do is solve for y:
In a
let's say the unmentioned angle is Y
so a line is 180° thus Y+145°=180°
we can get y=35°
so a triangle has inside angle sum of 180 and this gives us
X-25°+X+35°=180°
2X=170°
X=85°
for b
we know the inner angles of any four sided figure is 360°
X-35°+2X-75°+X+X=360°
5X=450°
thus X=90°
