Answer:

The number of pennies in the bank is 42

Step-by-step explanation:

Solution:

Given that ratio of pennies to quarters in a piggy bank is 14 : 3

Let 14x be the number of pennies in a piggy bank

Let 3x be the number of quarters in the piggy bank

To find: number of pennies

Given that there are 51 quarters

number of pennies in piggy bank + number of quarters in piggy bank = 51

14x + 3x = 51

17x = 51

x = 3

number of pennies = 14x = 14(3) = 42

Thus the number of pennies in the bank is 42

Find the length of the radius of the circle whose perimeter is xcm and the area is

$\bf \stackrel{\textit{perimeter}}{\textit{circumference}}\textit{ of a circle}\\\\ C = 2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=x \end{cases}\implies x = 2\pi r\implies \boxed{\cfrac{x}{2\pi }=r} \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ A=x \end{cases}\implies x = \pi \left( \boxed{\cfrac{x}{2\pi }} \right)^2\implies x = \pi \cdot \cfrac{x^2}{2^2\pi^2}$

$\bf x = \cfrac{x^2}{4\pi }\implies 4\pi x = x^2\implies \cfrac{4\pi x}{x}=x\implies \blacktriangleright 4\pi = x\blacktriangleleft \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{since the radius is}}{r = \cfrac{x}{2\pi }}\implies r =\cfrac{4\pi }{2\pi }\implies \blacktriangleright r = 2\blacktriangleleft$

Harlp needed ok thanks dudes

Solution:

A few definitions...

Rational number - Any integer, fraction, terminating decimal, or repeating decimal is classified as a rational number
Irrational number - All the real numbers which are not rational numbers.

Option A - Rational or Irrational?

1/2 + 1/3

Since both are known as fractions, they are rational numbers.

Option B - Rational or Irrational?

√2 + 5/2

√2 is classified as an Irrational number because if it is simplified, it does not result in any integer, fraction, terminating decimal, or repeating decimal.

Option C - Rational or Irrational?

1/√4 + 7/2
=> 1/2 + 7/2
=> 8/2 = 4

Since this is an integer, this is rational.

Option D - Rational or Irrational?

√9 + √4
=> √3 x 3 + √2 x 2
=> 3 + 2 = 5

Since this is an integer, this is rational.

In conclusion...

Option B is correct.
