Answer: 315\ ft^2

Step-by-step explanation:

In order to calculate the area of a rectangle, you can use the following formula:

A=lw

Where "l" is the lenght of the rectangle and "w" is the width.

In this case you know that this rectangle has a length of 21 feet and a width of 15 feet. Then:

l=21\ ft\\w=15\ ft

Therefore, you can substitute these values into the formula, getting that the area of this rectangle is:

A=(21\ ft)(15\ ft)\\\\A=315\ ft^2

Kenneth loaned $1,200 to his niece to buy a computer. Two years later, she paid him back the $1,200 along with an interest of $9
insens350 [35]

Answer:

<u>The  annual interest rate was 4%</u>

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Loan to Kenneth's niece to buy a computer = US$ 1,200

Duration of the loan = 2 years

Niece paid back to Kenneth = US$ 1,296

Annual interest rate = x%

2. Let's find the annual interest rate after 2 years, using the following formula:

FV = PV * (1 + x)

PV = Loan to Kenneth's niece to buy a computer = US$ 1,200

FV = Niece paid back to Kenneth = US$ 1,296

rate (r) = x

Replacing with the real values:

1,296 = 1,200 * (1 + x)

1.296/1.200 = (1 + x) (Dividing by 1,200 at both sides)

1.08 = 1 + x

1.08 - 1 = x (Subtracting 1 at both sides)

<u>0.08 = x</u>

This is the interest rate for two years, for finding the annual interest rate we divide it by 2, this way:

<u>0.08 / 2 = 0.04 * 100 = 4%</u>

Determinewhether the two lines areparallel, perpendicular, neither.X-3=6Y = 3x +4
Brums [2.3K]

we have the lines

x-3=6

x=6+3

x=9

this is a vertical line (parallel to the y-axis)

The slope is undefined

and

y=3x+4

The slope is m=3

Compare their slopes

1) Their slopes are not equal -----> are not parallel lines

2) Their slopes are not negative reciprocal -----> are not perpendicular lines

therefore

<h2>The answer is neither</h2>
