198 is 33% of what number?<br> Please show work<br> Can Robtobey help me and others :) ...?
Ghella [55]
First, you have to convert 33% to decimals by dividing it to 100. And that would be 0.33.
Then you want to know the 100 percent of 198 because it's just a 33% part of a whole.
You will have to divide 198 by 33% or 0.33 to get the whole. So the answer would be 600.

The perimeter of a parallelogram is 180 cm. One side exceeds the other by 10 cm. What are the lengths of adjacent sides of the p
torisob [31]

The lengths of adjacent sides of the parallelogram are 40 cm and 50 cm.

<h3>What is a parallelogram?</h3>

A parallelogram is a simple quadrilateral with two pairs of parallel sides.

Now, suppose a and be are two sides of parallelogram

Then, Perimeter P = 2( a+ b)

Now, it is given that perimeter of a parallelogram is 180 cm.

⇒ 2( a+ b) = 180

⇒ a + b = 90

It is also given that one side exceeds the other by 10 cm.

⇒ a = b + 10

Putting the value of a in above equation we get,

b + 10 + b = 90

⇒  2b = 90 - 10

⇒  2b = 80

⇒  b = 40 cm

Similarly,  a = b + 10

⇒  a = 40 + 10

⇒  a = 50 cm

Hence, the required sides of parallelogram are 40cm and 50cm.

let's bear in mind that an absolute value expression is in effect a piece-wise expression,  namely it has a ± versions of the same expression.
