Based on the information, the value of the piano after 16 years is $140.74.

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Using this formula to find the value of the piano, v, after t years.

CP = Principal(1-rate)[tex]^t[/tex]

Where:

Principal=$5,000

Rate=20%

Number of year = 16 years

Let plug in the formula;

=5,000(1-0.20)^16

=5,000(.80)^16

=$140.737

= $140.74 (Approximately)

Hence, the value of the piano after 16 years is; $140.74.

Answer: y+2x=15

Step-by-step explanation:

Given

Two points A and B are (4,7) and (6,3) respectively

Using two-point form

[tex]\Rightarrow \dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Putting values

[tex]\Rightarrow \dfrac{y-7}{x-4}=\dfrac{3-7}{6-4}\\\\\Rightarrow \dfrac{y-7}{x-4}=\dfrac{-4}{2}=-2\\\\\Rightarrow y-7=-2x+8\\\\\Rightarrow y+2x=15[/tex]

Answer: B.

Step-by-step explanation:

Suppose you have a L.L. Bean coupon of $63.60 and you want to know the final or sale price if the discount is 20 percent.

Using the formula (b) and replacing the given values:

Sale Price = Original Price - Amount Saved. So,

Sale Price = 63.60 - 12.72

Sale Price = $50.88 (answer).

This means the cost of the item to you is $50.88.

You will pay $50.88 for a item with original price of $63.60 when discounted 20%.

In this example, if you buy an item at $63.60 with 20% discount, you will pay 63.60 - 12.72 = 50.88 dollars.

Answer: $50.88

Step-by-step explanation:

Step 1: Find 20% of 63.60

20% of 63.60

20% = 20/100 = 0.2

0.2 × 63.60 = 12.72

20% of 63.60 is removed to get the selling price.

Step 2: Subtract

20% of 63.60 = 12.72

63.60 - 12.72 = 50.88

The selling price is $50.88.

Answer:

Number of marbles with Williams at the starting = 192

Step-by-step explanation:

Let total number of marbles with Williams = m

He lost marbles = 25% of the total number

                           = [tex]\frac{25}{100}\times m[/tex]

                           = [tex]\frac{m}{4}[/tex]

Remaining marbles with Williams = m - [tex]\frac{m}{4}[/tex]

                                                        = [tex]\frac{3m}{4}[/tex]

He gave marbles to his brother = [tex]\frac{1}{6}[/tex]th of the remaining marbles

                                                    = [tex]\frac{1}{6}\times \frac{3m}{4}[/tex]

                                                    = [tex]\frac{m}{8}[/tex]

Remaining marbles after giving marbles to his brother = 120

Therefore, [tex]\frac{3m}{4}-\frac{m}{8}=120[/tex]

[tex]\frac{6m}{8}-\frac{m}{8}=120[/tex]

[tex]\frac{5m}{8}=120[/tex]

m = [tex]\frac{120\times 8}{5}[/tex]

m = 192

Number of marbles with Williams at the starting = 192

Fig 1

<f=180-2×30=180-60=120

<D and <E are base angle of isosceles triangle.

Fig 2

AB=AC=BC=8

All the side of equilateral are equal and all interior angle also equal.

Answer:

Step-by-step explanation:

a) ΔFED is isosceles triangle. EF = ED

∠F = ∠D =x   {Angles opposite to equal sides are equal}

∠F + ∠E + ∠D = 180  {Angle sum property }

x  +x + 30 = 180

  2x + 30  = 180

           2x = 180 -30

           2x = 150

             x = 150/2

             x = 75

∠F = 75

b) All the angles are equal. So, it is an equilateral triangle. In equilateral triangle all sides are equal.

So, AB = 8

Answer: 1. 34 degrees+34 degrees=68 180-68=112 so x=112 degrees

2. 84+22=106 180-106=74 so x=74 degrees

3. 126+20=146 180-146=34 so x=34 degrees

4. both angles on both sides are 40 so 40+40=80 180-80=100 so x=100 degrees

Answer:

x=-2

Step-by-step explanation:

(6-x)/2 = 4

Multiply each side by 2

(6-x) /2 *2 = 4*2

6-x = 8

Subtract 6 from each side

6-x-6 = 8-6

-x = 2

Multiply each side by -1

x=-2

•Mutual respect. Respect means that each person values who the other is and understands the other person's boundaries.

•Trust. Partners should place trust in each other and give each other the benefit of the doubt.

•Honesty. ...

•Compromise. ...

Answer:

Step One: Divide both sides by 2

Step Two: Add 3 to both sides

Step Three: Multiply both sides by 1/6

Step-by-step explanation:

For step one, we can see that half of 12 is 6, half of 6 is 3 and half of 10 is 5.

For step two, we add 3 to the left to cancel out the -3 and add 3 to the left to make 8.

By process of elimination, we can see that C matches up to step 3.
