Find a number if: 3/7 of it is 2 1/14

Mathematics

Answer:

n = 2 1/14

Step-by-step explanation:

You have the equation (3/7)n = 2 1/14 and need to find the value of n.

First rewrite 2 1/14 as the improper fraction 29/14:

(3/7)n = 29/14.  Here the LCD is 14, so multiply both sides of this equation by that:

14(3/7)n = 14(29/14) = 29.  Simplifying this further, we get 6n = 29, so that:

n = 29/14, or  n = 2 1/14

Find the area of quadrilateral ABCD. [Hint: the diagonal divides the quadrilateral into two triangles.]
Rasek [7]

The area of the quadrilateral is 16.80 square units if the diagonal divides the quadrilateral into two triangles.

<h3>What is quadrilateral?</h3>

It is defined as the four-sided polygon in geometry having four edges and four corners. It has one pair of opposite congruent angles and the diagonals of a kite are perpendicular.

We have a quadrilateral shown in the picture.

The diagonal divides the quadrilateral into two triangles

The area of the quadrilateral = area of the triangle ADC + area of the

                                                   triangle ADB

= (1/2)3.42×4.39 + (1/2)5.44×3.42

= 7.5069 + 9.3024

= 16.80 square units

Thus, the area of the quadrilateral is 16.80 square units if the diagonal divides the quadrilateral into two triangles.
