Answer: 0.1 or 1/10

Step-by-step explanation:

$\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \:1\frac{1}{5}$

$1\frac{1}{5}=\frac{6}{5}$

$\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \frac{6}{5}$

$\frac{3}{4}-\frac{2}{3}$ $=\frac{9}{12}-\frac{8}{12}$

$=\frac{1}{12}$

$\frac{6}{5}\cdot \frac{1}{12}$

Cross, cancel common factor

$\frac{1}{2}\cdot \frac{1}{5}$

$=\frac{1}{10}$

Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.

Oliga [24]

Answer:

114 units²

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, so

AB = CD , that is

13x - 7 = 5x + 9 ( subtract 5x from both sides )

8x - 7 = 9 ( add 7 to both sides )

8x = 16 ( divide both sides by 8 )

x = 2

Then

5x + 9 = 5(2) + 9 = 10 + 9 = 19

3x = 3(2) = 6

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height ), thus

A = 19 × 6 = 114 units²
