$18, P = $200, r = ?, t = 1.5 years. Find the annual interest rate.
faust18 [17]

                                                  Question 1)

Given

Interest I = $18

Principle P = $200

t = 1.5 years

To determine

Interest rate r = ?

Using the formula

P = Irt

r=\frac{I}{Pt}

susbtituting I = 18, t = 1.5 and P = 200

r=\frac{18}{\left(200\times 1.5\right)}

r = 0.06

or

r = 6%       ∵ 0.06 × 100 = 6%

Therefore, we conclude that the interest rate required to  accumulate simple interest of $18.00  from a principal of $200 over 1.5 years is 6% per year.

                                                    Question 2)

Given

Interest I = $60

Principle P = $750

Interest rate = 4% = 0.04

To determine

Time period t = ?

Using the formula to calculate the time period

P = Irt

t\:=\:\frac{P}{Ir}

t=\frac{60}{\left(750\times 0.04\right)}

t = 2 years

Therefore, the time required to  accumulate simple interest of $ 60.00

from a principal of $ 750 at an interest rate of 4% per year  is 2 years.

How do you find the area and perimeter of a rectangle. And how do you find the area and perimeter of a square?
cupoosta [38]

Answer:

The perimeter of a rectangle is P = 2 b + 2 h , where is the base (or width) and is the height (or length). If a rectangle is a square, with sides of length , the formula for perimeter is P s q u a r e = 2 s + 2 s = 4 s and the formula for area is A s q u a r e = s ⋅ s = s 2

3x^2+17x-9/x+4 what is the quotient
zvonat [6]

Answer:

The quotient of given expression is (3x+5).

Step-by-step explanation:

The given expression is

\frac{3x^2+17x-9}{x+4}

The coefficients of dividend are 3,17 and -9.

Use synthetic division to divide 3x^2+17x-9 and x+4.

The bottom row represents the coefficient of quotient and remainder.

The given expression can be written as

\frac{3x^2+17x-9}{x+4}=3x+5-\frac{29}{x+4}

Therefore the quotient of given expression is (3x+5).
