This most definitely has to be a rhombus since it is a form of a square with 4 congruent sides where a rectangle only has 4 right angles.
To clarify, a trapezoid only has one pair of parallel sides if you were wondering.

Simplify the following expression. 3^11/5 divided by 3^-9/5

san4es73 [151]

Answer:

Answer is 81.

Step-by-step explanation:

Given two expressions are $3^{\frac{11}{5} }$ and $3^{-\frac{9}{5} }$

Now we divide first expression by the second.

$\frac{3^{\frac{11}{5} }}{3^{-\frac{9}{5} } }$

$3^{\frac{11}{5} }.3^{\frac{9}{5} }$

$3^{\frac{11}{5}+\frac{9}{5}} = 3^{\frac{20}{5} }=3^{4}=81$

Therefore 81 is the answer.

You multiply two integers. You increase one of them by 1 and decrease the other

snow_tiger [21]

Integers are numbers without decimals

The integers could you have multiplied are 9 and 2

Let the numbers be x and y

So, we have:

$\mathbf{x \times y}$

Increase x by 1 and reduce y by 1.

So, we have

$\mathbf{(x +1) \times (y -1) = 6 + xy }$

Open brackets

$\mathbf{xy -x + y - 1 = 6 + xy}$

Subtract xy from both sides

$\mathbf{ -x + y - 1 = 6}$

Collect like terms

$\mathbf{ -x + y = 6 + 1}$

$\mathbf{ -x + y = 7}$

Rewrite as:

$\mathbf{ y -x= 7}$

The above means that, the difference between the integers is 7.

There are several integers that fit the above <em>description</em>;

One possibility is: 9 and 2

Answer:

See Explanation

Step-by-step explanation:

Given

$T_1 = 2\ hours$ ---------- A to B

$T_2 = 4\ hours$ ---------- B to C

Required

Determine the average speed of Mr. Ali's journey

To do this, we have to calculate the total distance covered.

i.e.

Distance = Town A to B + Town B to C

$Total\ Time = T_1 + T_2$

$Total\ Time = 2 + 4$

$Total\ Time =6$

The distance between the towns are not given. So, I'll make an assumption.

<em>-------------------------------------------------------------------------------------------------------------</em>

<em>Assume:</em>

<em>Town A to B = 5km</em>

<em>Town B to C = 10km</em>

<em></em>

<em></em> $Total\ Distance = 5km + 10km$ <em></em>

<em></em> $Total\ Distance = 15km$ <em></em>

<em>-------------------------------------------------------------------------------------------------------------</em>

Average Speed is then calculated as:

$Average\ Speed = \frac{Total\ Distance}{Total\ Time}$

$Average\ Speed = \frac{15}{6}$

$Average\ Speed = 2.5km/hr$
