After 5 years, a $2,450 investment is worth $3,123.75.
kondaur [170]

Answer:

5.5%

Step-by-step explanation:

To solve this problem we can use a modified version of the simple interest formula which is shown below:

r=\frac{I}{Pt}

<em>I = interest amount</em>

<em>P = principal amount</em>

<em>t = time (years)</em>

<em />

The first step is to find the interest gained from the investment.

3,123.75-2,450=673.75

Next, plug in the values into the equation:

r=\frac{673.75}{(2,450)(5)}     Multiply the bottom values

r=\frac{673.75}{12,550}         Divide the values

r=.055

The last step is to convert 0.055 into a percent:

0.055(100)=5.5

The interest rate is 5.5%

HELP ASAP!! 10 minuets left! lots of points
VLD [36.1K]

Answer:

130 yd^2

Step-by-step explanation:

First we find the area of the triangle

A = 1/2 b h  where b is 10 and h= 6.25

A = 1/2 (10) * 6.25

   = 31.25 yd^2

Then we find the area of rectangle A

A = l*w  where l is 10 and w = (7.5-2.5) = 5

A = 10 * 5

   = 50 yd^2

Then we find the area of rectangle B

A = l*w  where l is 6.5 and w = 7.5

A = 6.5 * 7.5

   = 48.75 yd^2

The total area is found by adding them together

A triangle + rectangle A  + rectangle B

31.25+50 + 48.75

130 yd^2
