The heights of two similar parallelograms are 16 inches and 20 inches. Their

Fittoniya [83]

Answer: $x=\dfrac{25}{21}$

Step-by-step explanation:

Area of parallelogram = Base x height

If two parallelograms are similar, then their corresponding sides are proportional.

That means, $\dfrac{\text{Area of first parallleogram}}{\text{Area of second parallleogram}}=\dfrac{\text{height of first parallelogram}}{\text{height of second parallelogram}}$

$\Rightarrow \dfrac{3x+5}{9x}=\dfrac{16}{20}\Rightarrow \dfrac{3x+5}{9x}=\dfrac{4}{5}\\\\\Rightarrow 5(3x+5)=4(9x)\\\\\Rightarrow\ 15x+25 = 36x\\\\\Rightarrow\ 36x-15x=25\\\\\Rightarrow\ 21x = 25\\\\\Rightarrow\ x=\dfrac{25}{21}$

Hence, $x=\dfrac{25}{21}$

1 l Find the perimeter of a circle whose area is 154 cm?

Alenkasestr [34]

Answer:

44

Step-by-step explanation:

The formula to find to area of a circle is $\pi r^{2}$ = Area

The perimiter formula is $2\pi r$ = Perimeter

Since we know the area (154cm) we can find the radius (r) with the formula.

You first have to find what the radius of the circle is with.

$\pi =3.14$

$\pi r^{2}$ = 154

3.14 $r^{2}$ =154

Now simplify.

$r^{2}$ =49 (rounded)

r=7

Now we can find the perimeter with the formula above.

$2\pi r$ = P

Now plug in.

2(3.14)(7)= P

44=P (Rounded)
