Answer:
a dot in an equation means multiplication
Answer:
13
Step-by-step explanation:
We can consider the complex number
as point with coordinates
where
is real part of the complex number and
is an imaginary part of the complex number.
The distance between two complex numbers is exactly tha distance between two points corresponding to each number.

Now find the distance between A and B:

The mode is 85, because it is the most occurring in the data set.

Answer: a) 92 yards, b) 29.29 yards and 672.99 sq. yd.
Step-by-step explanation:
Since we have given that
Area of square pen = 529 sq. yd
Let the length of each side be 'a'.
As we know the formula for "Area":

So, the perimeter of the square pen is given by

So, perimeter of square pen = Perimeter of round pen

So, the diameter of round pen is 
And the area of round pen is

Hence, a) 92 yards, b) 29.29 yards and 672.99 sq. yd.
Answer:
The plane can fly 760 miles in 4/3 hours.
Step-by-step explanation:
Given that:
An airplane can cruise at 570 miles per hour.
We have to find the distance travelled by train in 4/3 hours.
Distance = Speed * Time
Distance = 
Distance = 
Distance = 760 miles
Hence,
The plane can fly 760 miles in 4/3 hours.
