Investors benefit from compound interest, although the term "investors" can indicate many different things. For instance, banks profit from compound interest when they make loans and then reinvest the interest they earn to make more loans. When holders of deposits receive interest on their bank accounts, bonds, or other investments, they also profit from compound interest.

The concept of compound interest applies outside of contexts where the phrase is normally employed, such as bank accounts and loans, despite the fact that the term compound interest includes the word interest.

Let the rate of interest be 2.16 % per year

Time n = 5 years

Amount A = $6999.31

A = P(1 + R/100)ⁿ

substitute the values in the above equation, we get

⇒ 6999.31 = P (1  + 2.16/100)⁵

simplifying the equation, we get

⇒ P = 6290

Therefore, the amount of investment would be $ 6290.

A constant of proportionality is a constant value for the ratio of two proportional quantities. If the ratio or product is constant, the two variables are proportional. The value of the constant of proportionality depends on the type of relationship between the two given quantities (positive versus inverse variation).

According to the question:

From the above mentioned , the individual ratio of number of birdhouse (b) cans of paints is:

Now,

For 1st  pair,

If G is the incenter of triangle ABC the values of the unknown sides are

a) GD = 12

b) BG = 13.42

c) FC = 35

d) BF = 6

Considering that G is the incenter of triangle ABC, we have that

Using the right triangle CDG and applying Pythagoras theorem given by  the formula

hypotenuse² = opposite² + adjacent²

plugging the values as in the problem

GC² = GD² + DC²

37² = GD² + 35²

GD² = 37² - 35²

GD² = 144

take square root of both sides

GD = √144

GD = 12

Using the right triangle BEG to solve for BG

BG² = EB² + GE²

BG² = 6² + 12²

BG² = 180

take square root of both sides

BG = √180

BG = 13.42

Using the right triangle CFG to solve for FC

GC² = GF² + FC²

rearranging the equation

FC² = GC² - GF²

FC² = 37² - 12²

FC² = 1225

take square root of both sides

FC = √1225

FC = 35

Using the right triangle BFG to solve for BF

BG² = GF² + BF²

rearranging the equation

BF² = BG² - GF²

An equation for the cost of the cheaper brand is y = 60x + 1,800.

An equation for the cost of the more expensive brand is y = 50x + 2,600.

The cost of running the cheaper unit for 36 months is $3,960.

The number of months for which the cost of both brands would be equal is 8 months.

In order to write an equation that model this situation, we would assign variables to the time and cost respectively, and then translate the word problem into algebraic equation as follows:

Since a brand cost $1800 to buy with a monthly operation fee of $60, an equation for the cost of this cheaper brand is given by:

y = 60x + 1,800.

When x = 36 months, the cost of running the cheaper unit is given by:

y = 60(36) + 1,800.

y = $3,960.

For the more expensive brand, we have:

y = 50x + 2,600.

Next, we would determine the number of months for which the cost of both brands would be equal;

50x + 2,600 = 60x + 1,800

60x - 50x = 2,600 - 1,800

10x = 800

x = 800/10

x = 8 months.

The metal bar would displace 0.018 liters of water.

Volume is the measure of the amount of space occupied by an object or substance. It is often represented by the symbol 'V' and is typically measured in units such as liters (L), cubic meters (m^3), or gallons (gal). In three-dimensional space, the volume of an object is calculated by multiplying its length, width, and height (or depth). In two-dimensional space, the area of an object can be calculated by multiplying its length and width.

The volume of the metal bar is 3 cm x 3 cm x 2 cm = 18 [tex]cm^3[/tex]. The density of water is 1 g/[tex]cm^3[/tex]. To find the volume of water displaced, we need to convert the volume of the bar from cubic centimeters to liters.

Company A charges $5.00 and 6 cents much more for x miles than Company B. The solution is obtained using arithmetic operations.

There are four basic operations which are listed as follows: Addition(‘+’): This operation deals with finding the sum. Subtraction(‘-’): This operation deals with finding the difference.   Multiplication(‘×’): This operation deals with finding the product. Division(‘÷’): This operation deals with finding the quotient.

In order to find how much more does company A charge than company B, we need to subtract the charges of company B from that of Company A.

So, on subtracting we get,

$55.50 and 15 cents - $50.50 and 9 cents = $5.00 and 6 cents per mile.

For x miles, we multiply $5.00 and 6 cents by x miles.

Also, we could convert dollars to cents by multiplying it by 100.

as $1 =100 cents.

5565 - 5059 cents = 506 cents.

For x miles, 506x cents.

A quadrilateral with parallel sides equal to one another and four equivalent vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel. The area of a rectangle is given as the product of the length and breadth of the rectangle.

The given parameters are:

The straw is said to fit into the box diagonally from the bottom.

So, the length (s) of the straw is calculated as:

[tex]s=\sqrt{l^{2}+w^{2}+h^{2} }\\[/tex]
