Answer:
3
Step-by-step explanation:
Triangles with the same shape but different size are proportional. Proportional means that their side lengths form equal ratios. To solve for x, set up a proportion.
The ratios we will create will be where each long and short are corresponding sides from each triangle.
So write:
To solve, cross multiply numerator with denominator.
4(2.25) = 3(x)
9 = 3x
3 =x
Answer:
$1,577.74
Step-by-step explanation:
You are going to want to use the continuous compound interest formula, which is shown below.
<em>A = total </em>
<em>P = principal amount </em>
<em>r = interest rate (decimal) </em>
<em>t = time (years) </em>
<em />
First change 3% to its decimal form:
3% -> -> 0.03
Next, we can plug in the values into the equation:
The last step is to subtract 8,000 from 9,577.74:
The total interest earned is $1,577.74
