Answer:
ruler placement postulate is important to define relative positioning between points.
Although both A & C are possible, we don't consider a line to have an "origin". A distance can have an origin, so the answer must be A.
Answer:
The speed of wind is 75 miles / hour
Step-by-step explanation:
Let's assume
speed of airplane is x miles /hour
speed of wind is y miles /hour
An airplane travels 600 miles against the wind in 4 hours
against wind means resultant speed will be less
so, speed =x-y
total distance traveled in 4 hour is
and this has to be equal to 600
Divide both sides by 4
makes the return trip with then same wind in 2 hours
with wind means resultant speed will be more
so, speed =x+y
total distance traveled in 2 hour is
and this has to be equal to 600
Divide both sides by 2
So, we get system of equations
now, we can solve it by adding both equations
now, we can solve for x
now, we can find y by plugging x into any one equation
Answer:
DAMMIT I BIT MY FINGER
Step-by-step explanation:
The exact circumference of the circle is 
The approximate circumference of the circle is 
Explanation:
The diameter of the circle is 
Now, we shall find the circumference of the circle.
The formula to determine the circumference of the circle is given by
Where C is the circumference , 
is 3.14 and 
is the diameter of the circle.
The exact circumference of the circle is given by
Multiply both numerator and denominator by 100, we get,
Converting 
into mixed fraction, we get,
Thus, the exact circumference of the circle is
The approximate value of the circumference can be determined by dividing the value
Thus, the approximate circumference of the circle is
