38/50
19/50.
Simplify both the numerator and denominator by 2 (greatest common factor).
Answer:
2/3 hours is equivalent to 40 minutes.
Step-by-step explanation:
Divide an hour, (60 minutes) by three to get 20, which is equivalent to a third. So to put it into perspective:
1/3: 20
2/3: 40
3/3(1): 60

If the height of the pyramid is 71 meters and the angle of elevation of the base of the pyramid is 42°, then the length of the base of the <span>pyramid is
2(71) tan 42 = 127.86

If you graph y=7x-9 and y=3x-1 the two lines will intersect at one point. That is how you graphically "solve" the system of equations.
Both of these lines are of the form y=mx+b where m is the slope and b is the y-intercept.
So for y=7x-9, the slope is 7 and the y-intercept is -9
For y=3x-1, the slope is 3 and the y-intercept is -1
....
The solution for this system occurs when both coordinates are equal to each other so we can say:
7x-9=3x-1 subtract 3x from both sides
4x-9=-1 add 9 to both sides
4x=8 divide both sides by 4
x=2, making y=3x-1 become:
y=3(2)-1=6-1=5, so the solution to the system of equations is:
(2,5)
Common difference = 1/3 - 2/3 = 1-2 / 3 = -1/3
In short, Your Answer would be -1/3
Hope this helps!
