20 years is the answer.

A= R(1+r)^ t

A-415    

R=230

r=3%

415=230 (1+3%)^ t

t=log1.03  315/230

t=19.89 (use calculator)

David will invest at least 20 years.

An investment is a dedication of an asset to achieve an increase in value over a period of time. Investing requires the sacrifice of current assets such as time, money and effort. In finance, the purpose of an investment is to generate a profit on the invested asset

The most common example of an investment type. Investment is generally what you want to use in the future with the aim of generating regular cash flow or increasing the value of something over time so that you can sell it at a higher price than you purchased.

47. Which of the following represents 0.2% of 1/5?
erica [24]

First think of what 0.2% is as a fraction,

0.2\%=\frac{0.2}{100}=\frac{2\cdot10^{-1}}{10^2}=\frac{2}{10^3}=\frac{2}{1000}

Now multiply the fraction by a fifth,

\frac{2}{1000}\cdot\frac{1}{5}=\frac{2}{5000}

Which then simplifies to,

\frac{2}{5000}=\boxed{\frac{1}{2500}}

Hope this helps :)

16 tablespoons equals 1 cup create a double number line that shows how many tablespoons you would need to use to make 5 cups of
gladu [14]
16tbsp/1cup.
Multiply by 5 for 5 cups (I recommend cross multiplying with fractions)
80tbsp/5cups
Multiply by 1.25
20tbsp/1.25cups
Multiply by 2.7
43.2tbsp/2.7cups
Since you can’t have .2 of a table spoon, we need to round up.
44tbsp/2.7cups

Total tbsp:80+20+44tbsp=144tbsp

We would need 144 tablespoons for 8.95 cups (9 for the same reason that we rounded up with the table spoons)

VK = VY+YK by the segment addition postulate. Basically adding two segments along a straight line forms a longer segment. In this case, VY and YK combine to form VK

Since VK = x and VY = 22, this means...
VK = VY+YK 
x = 22+YK 
x-22 = YK
YK = x-22

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

Notice the arc marks where the point T is located. These markings tell us that the two angles VTY and YTK are congruent angles. Because of this, we can use the angle bisector theorem which says that the ratio of the corresponding sides are congruent.

In short, we can form this ratio
VT/VY = KT/KY
which is the ratio of the side adjacent to the angle, to the side opposite the angle

Plug in the given values and solve for x
VT/VY = KT/KY
77/22 = 87.5/(x-22)
77(x-22) = 22*87.5
77(x-22) = 1925
77x-77*22 = 1925
77x-1694 = 1925
77x = 1925+1694
77x = 3619
x = 3619/77
x = 47

If p and q are all positive integers and the maximum integer not greater than
garik1379 [7]

Answer:

  • 71

Step-by-step explanation:

<u>As per question we have:</u>

  • p > 0, q > 0
  • 31p/8q ≤ 5 ⇒ 31p ≤ 40q

Since 31 and 40 have no common factors, the minimum values of p and q are 40 and 31 respectively.

<u>So the minimum value of p + q is:</u>

  • 40 + 31 = 71
