<h3>Answer: 7366.96 dollars</h3>

========================================================

Use the compound interest formula:

A = P(1+r/n)^(n*t)

where in this case,

A = 12000 = amount after t years

P = unknown = deposited amount we want to solve for

r = 0.05 = the decimal form of 5% interest

n = 1 = refers to the compounding frequency (annual)

t = 10 = number of years

-------

Plug all these values into the equation, then solve for P

A = P(1+r/n)^(n*t)

12000 = P(1+0.05/1)^(1*10)

12000 = P(1.05)^(10)

12000 = P(1.62889462677744)

12000 = 1.62889462677744P

1.62889462677744P = 12000

P = 12000/1.62889462677744

P = 7366.95904248911

P = 7366.96

The answer is £140

First you find 20% of 1200 (which is basically 20 times 12) which gives you £240.

You add £240 to £1200 which is £1440

Then you take £300 off £1440 since he already paid the deposit.

That leaves you with £1140

1140 divided by 10 is 114

Identify the segment bisector of XY. Then find XY<br><br>​
Aneli [31]

Answer:

  • bisector: PQ
  • length: 26

Step-by-step explanation:

The midpoint (W) of XY is also on segment PQ, so PQ is the bisector of XY.

The diagram identifies the length of XW as 13. Since the length of WY is the same, the length of XY is 2×13 = 26.

Answer:

<em>The perimeter of the bedroom floor is 44 ft</em>

Step-by-step explanation:

<u>The Perimeter of a Rectangle</u>

Given a rectangle of width W and length L, the perimeter is the sum of all four sides:

P = 2W + 2L

We know a rug of dimensions 6 ft x 10 ft is located at the center of a bedroom floor and there are 1.5 ft exposed on all four sides of the bedroom.

Adding this length to each side, we have the dimensions of the bedroom as:

6 + 1.5 + 1.5 = 9 ft

10 + 1.5 + 1.5 = 13 ft

Thus, the perimeter of the bedroom floor is:

P = 2*9 + 2*13 = 44 ft

The perimeter of the bedroom floor is 44 ft
