JKLM is a parallelogram

=> JK // LM

=> KJM + LMJ = 180⁰

<=> 56⁰ + LJM + 72⁰ + 27⁰ = 180⁰

=> LJM = 180⁰ - 56⁰ - 72⁰ - 27⁰ = 25⁰

A 75% increase followed by a 33 1/2% decrease

o-na [289]

After 75% increase followed by a 33 1/2% decrease the net increased is 16.375%.

<u>Solution:</u>

Need to determine net percentage increase or decrease when a value is increased by 75% and then decreased by $33 \frac{1}{2} \%$ that is 33.5%.

Let’s assume initial value be represented by variable x.

$75 \% \text { decrease means } x+75 \% \text { of } x=x+\frac{75}{100} x=x+0.75 x=1.75 x$

Now there is decrease of 33.5%

$\begin{array}{l}{33.5 \% \text { decrease means } 1.75 x-33.5 \% \text { of } 1.75 x=1.75 x-\frac{33.5}{100} \times 1.75 x} \\\\ {=1.75 x-(0.335 \times 1.75) x=1.75 x-0.58625 x} \\\\ {=1.16375 x}\end{array}$

$\text { So increase in percentage }=\frac{\text { final value-initial value}}{\text { intial value }}$

$=\frac{1.16375 x-x}{x} \times 100=16.375 \%$

Hence after 75% increase followed by a $33 \frac{1}{2} \%$ decrease the net increased is 16.375%.

If the ratio of the area of two squares is 9:1 find the ratio of their perimeter

Lena [83]

Answer:

3:1

Step-by-step explanation:

area is 2D while the perimeter is a length which is 1D. you can also about this in how the area is units squared while the perimeter is just units. so we need the square roote of 9 and 1, sqrt(9) = 3, sqrt(1) = 1. so the ratio of the perimeter is 3:1
