What is the simplest form of 9/16

nekit [7.7K]

9/16 is already in simplest form. 9 cannot be divided by anything that 16 can. 9 can be divided by 3, but 16 can't be.

An equilateral triangle has sides of length(3k-2)units. A regular pentagon(5 sides) has sides of (2k+0.5)units. If the perimeter

Vitek1552 [10]

The length of side of triangle is 5 units and length of side of pentagon is 1.5 units.

<u>SOLUTION:</u>

Given, An equilateral triangle has sides of length $(3k-2)$ units.

Then, perimeter of the triangle will be $3 \times(3 k-2)=9 k-6$

A regular pentagon (5 sides) has sides of $(2k+0.5)$ units.

Then, perimeter of the pentagon will be $5 \times(2 k+0.5)=10 k+2.5$

We have to find the dimensions of each shape . Now, the perimeter of the triangle is twice the perimeter of the pentagon,

So, $\text {perimeter of triangle} = 2\times \text{perimeter of pentagon}$

$\begin{array}{l}{\rightarrow 9 k-6=2(10 k+2.5)} \\\\ {\rightarrow 9 k-6=20 k+5} \\\\ {\rightarrow 20 k-9 k=-6-5} \\\\ {\rightarrow 11 k=-11} \\\\ {\rightarrow k=-1}\end{array}$

Then, length of side of triangle $= 3(-1)-2 = - 5$

Length of side of pentagon $= 2(-1) + 0.5 = - 1.5$

We have to neglect, negative sign as lengths can’t be negative. Even if we change the sign above all conditions are satisfied.

Can you help with this please.

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - <u>two </u><u>points </u><u>P </u><u>(</u><u> </u><u>5</u><u> </u><u>,</u><u> </u><u>1</u><u>0</u><u> </u><u>)</u><u> </u><u>and </u><u>R </u><u>(</u><u> </u><u>1</u><u>2</u><u> </u><u>,</u><u> </u><u>1</u><u>4</u><u> </u><u>)</u><u> </u><u>on </u><u>the </u><u>c</u><u>artesian </u><u>plane</u>

To find - <u>distance </u><u>between </u><u>the </u><u>two </u><u>points</u>

<u>Using </u><u>the </u><u>distance </u><u>formula</u> ~

$\qquad\underline{d(PR) = \sqrt{( x_{2} - x_{1}) {}^{2} + ( y_{2} - y_{1}) {}^{2} }} \\ \\$

we have ,

$\longrightarrow x_{1} = 5 \\ \longrightarrow x_{2} = 12 \\ \\ \longrightarrow \: y_{1} = 10 \\ \longrightarrow \: y_{2} = 14$

<u>substituting</u><u> </u><u>the </u><u>values </u><u>in </u><u>the </u><u>formula </u><u>,</u><u> </u><u>we </u><u>get</u>

$d(PR) = \sqrt{(12-5) {}^{2} + (14-10) {}^{2} } \\ \\ \implies \: d(PR) = \sqrt{(7) {}^{2} + ( 4) {}^{2} } \\ \\ \implies \: d(PR) = \sqrt{49 + 16} \\ \\ \implies \: d(PR) = \sqrt{65} \\ \\ \implies \: d(PR) = 8.1 \: units \: (approx)$

hope helpful :)
