Again set a proportion
x/4=35.25/1
=x=4(35.25)
x=141
Therefore the boat traveled 141 kilometres.
The answer is C.
First and foremost that is a quadrilateral, because it is a 4-sided figure. If it was a trapezoid it would have only 1 set of parallel lines. So NOT a trapezoid. It is a parallelogram because parallelograms have 2 pair of parallel lines. It is not a rhombus because a rhombus has 4 equal length sides. So it's not a square either. It is not a rectangle either because rectangles have 4 right angles and this one does not. So your choices are 1 and 3.
Answer:
Answer Choice A.
Step-by-step explanation:
To find 4C, multiply each and every one of the 6 numerals inside the determinant bars by 4:
48 0 6
4C = 4 -24 28
This is Answer Choice A.
The circumference of a circle is calculated using the following equation:

Where d is equal to the diameter (the length of a straight line from one side of the circle to the other side).
We know that the diameter of the circle given (also known as AB) is equal to 20 cm.
We can then plug this into the equation and solve for the circumference:

Since the question asks for the answer to be in terms of

, this is as far as we need to go. So
the circumference of the circle is:
or D.
