⇒A Number is said to be Rational, if it can be written in the form of \frac{p}{q}, otherwise it is Irrational.

⇒Decimal expansion of Rational is either Terminating or Non Terminating Repeating.For example ,0.234, 0.222222........,

⇒Decimal expansion of Irrational is always "Non Terminating non repeating".For example ,√2,√3, 0.23023002300023.......,

A.\rightarrow 0.144-----\text{Rational}\\\\B.\rightarrow \sqrt{0.144}\\\\=\sqrt{\frac{144}{1000}}\\\\=\frac{1.2}{\sqrt{10}}-----\text{Irrational}

⇒∵ ,√10, is Irrational.

C.\rightarrow \sqrt{0.0144}\\\\=\sqrt{\frac{144}{10000}}\\\\=\frac{12}{100}\\\\=0.12-----\text{Rational}

What is the perimeter of the parallelogram shown below? And how did you get that answer.
romanna [79]

The answer is 194

Explanation:

A parallelogram is a tilted rectangle and possess all the features of rectangle except it's symetry

Opposite sides of a parallelogram are equal in length

So if One side is 48 then the opposite length the is also 48 and vice versa, Same for the 49 too

My calculations were 49+49+48+48=

OR

omar tariq has a credit card that uses the unpaid balance method to compute the finance charge. His monthly periodic rate is 2.4
Korvikt [17]

Answer:

(a) unpaid balance = $667.95

(b) Previous balance = $761.67

(c) his new balance = $683.98

Step-by-step explanation:

In the question, we are given the following:

Monthly periodic rate = 2.4%, or 0.024

Curren charges = $256.28

Total payment made = $350

Finance charge = $18.28

Therefore, we now proceed as follows:

(a) unpaid balance

This can be calculated as follows:

Unpaid balance = Previous balance + Current charges - Total payment made ................. (1)

Note that from part (b), Previous balance is equal to $761.67.

Substituting this and other values from the question into equation (1), we have:

Unpaid balance = $761.67 + $256.28 - $350 = $667.95

(b) Previous balance

This can be calculated as follows:

Previous balance = Finance charges / Monthly periodic rate = $18.28 / 2.4% = $18.28 / 0.024 = $761.67

(c) his new balance

This can be calculated as follows:

New balance = Unpaid balance * (1 + Monthly periodic rate) = $667.95 * (1 + 2.4%) = $667.95 * (1 + 0.024) = $667.95 * 1.024 = $683.98
