Rita has a loan of $45,580. This loan has a simple interest rate 4% per year . What is the amount of interest that rRta will be

Feliz [49]

Answer:

$1,823.2

Step-by-step explanation:

Simple interest is calculated using the formula

I = P X R X T

where I is the interest amount

P is the principal amount: 45,580.

R is the interest rate which is 4 %, or 0.04%

T is time, One year.

I = $45,580 x 0.04 x 1

I = $1,823.2 x 1

I = $1,823.2

Identify which of the following statement(s) is always true?

julia-pushkina [17]

Answer:

Statement 3

Step-by-step explanation:

Statement 1: For any positive integer n, the square root of n is irrational.

Suppose n = 25 (25 is positive integer), then

$\sqrt{n}=\sqrt{25}=5$

Since 5 is rational number, this statement is false.

Statement 2: If n is a positive integer, the square root of n is rational.

Suppose n = 8 (8 is positive integer), then

$\sqrt{n}=\sqrt{8}=2\sqrt{2}$

Since $2\sqrt{2}$ is irrational number, this statement is false.

Statement 3: If n is a positive integer, the square root of n is rational if and only if n is a perfect square.

If n is a positive integer and square root of n is rational, then n is a perfect square.

If n is a positive integer and n is a perfect square, then square root of n is a rational number.

This statement is true.
