Answer:

The present value is  PV  = \$ 396,987

Step-by-step explanation:

From the question we are told that

   The  interest payment per year is  C =  \$ 85

    The principal payment is  P =  \$ 1000

     The  duration is  n =  8   years

      The  interest rate is  r =  10\%  =  0.10

The present value is  mathematically represented as

      PV  =  [ \frac{C}{r} *  [1 - \frac{1 }{ (1 +r)^n} ] + \frac{P}{(1 + r)^n}  ]

substituting values

      PV  =  [ \frac{85}{0.10} *  [1 - \frac{1 }{ (1 +0.10)^8} ] + \frac{1000}{(1 + 0.10)^ 8}  ]

      PV  = \$ 396,987

suter [353]

Answer:

  • 1/200 pounds

Step-by-step explanation:

<u>Given ratio</u>

  • 1/8 pound ⇔ 25 square feet

<u>To find </u>

  • x ⇔ 1 square foot

<u>Divide both sides by 25</u>

  • 1/8÷25 pounds ⇔ 25÷25 square feet
  • 1/200 pounds ⇔ 1 square foot

The original quantity is 20 and the new quantity is 15. Adam incorrectly says the percent decrease is about ​14.29%. What is the
Yuki888 [10]

Answer: A. divided the difference of the two quantities by the sum of the two quantities.

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

Explanation:

The difference of the quantities is 20-15 = 5

The sum of the quantities is 20+15 = 35

Dividing those results leads to 5/35 = 0.142857 which rounds to 0.1429

That converts to 14.29%

This is likely the path Adam took. This path is incorrect. The correct steps are shown below

---------------------

Difference = 20-15 = 5

Divide the difference over the original quantity

5/20 = 1/4 = 0.25 = 25%

We have a 25% decrease because the new quantity (15) is smaller than the old quantity (20)

----------------------

Here's another way to approach the problem

A = old value = 20

B = new value = 15

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (15-20)/20 ] * 100%

C = (-5/20)*100%

C = -0.25*100%

C = -25%

The negative C value means we have a negative percent change, ie we have a percent decrease. So this is another way to get a 25% decrease.

A kite has a height of 36 inches and a width of 30 inches. Explain how to use the area formula for a triangle to find the area o
mote1985 [20]

Height of the kite is = 36 inches.

Width of the kite is = 30 inches

One of the ways to find the area is to draw a vertical line to break the kite into two equal triangles. Mark the base as 36 inches and height as 15 inches .

Now we will use the formula area=\frac{1}{2}*base*height to find the area of each triangle. Then we will add both the areas to find the area of the kite.

Area of 1 triangle = \frac{1}{2}*36*15 = 270 square inches

Area of the 2nd triangle is also = 270 square inches

Hence, area of the kite = 270+270 = 540 square inches
