Area of a rhombus = 1/2 x diagonal 1 x diagonal 2
= 1/2 x 15 1/2 x 13 1/5
= 1/2 x 31/2 x 66/5
=31/2 x 33/5
= 1023/10
= 102.3

Answer: Option 'B' is correct.

Step-by-step explanation:

since we have given that

Time taken to build a cabinet by Genna = 4 hours.

Time taken to build a cabinet by Claude = 3 hours

Now, time taken by both Genna and Claude to build a cabinet together is to be find.

Work done by Genna is given by

$\frac{1}{4}$

Work done by Claude is given by

$\frac{1}{3}$

According to question,

$\frac{1}{4}+\frac{1}{3}=\frac{1}{x}\\\\\frac{3+4}{12}=\frac{1}{x}\\\\\frac{7}{12}=\frac{1}{x}\\\\x=\frac{12}{7}\\\\x=1\frac{5}{7}\ hours$

Hence, Option 'B' is correct.

Cual es la simplificacion de 66/81

Karo-lina-s [1.5K]

Answer:

Hence the simplification of $\dfrac{66}{81}$ is $\dfrac{22}{27}$

Step-by-step explanation:

" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter),

for example: Simplification of a fraction to an irreducible fraction ".

Here we are given a fraction as:

$\dfrac{66}{81}$

As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.

As 66=3×22 and 81=3×27

Hence $\dfrac{66}{81}=\dfrac{3\times22}{3\times27}=\dfrac{22}{27}$
