Alex invests $2,000 in a company's stock. After a year, the value of Alex's stock has increased to $2,500. What rate of return h

Kay [80]

The rate of interest is 25%

<u>Explanation:</u>

Given:

Principal, P = $2,000

Amount, A = $2500

Time, t = 1 year

Rate of Interest, r = ?

We know:

$Amount = P(1+\frac{r}{100})^t$

On substituting the value we get:

$2500 = 2000 (1 + \frac{r}{100})^1\\ \\\frac{25}{20}= (1+\frac{r}{100})\\$

$\frac{5}{20} = \frac{r}{100}\\ \\r = \frac{100 X 5}{20} \\\\r = 25$

Therefore, the rate of interest is 25%

Drag each tile to the correct location on the algebraic problem. Not all tiles will be used,

Tema [17]

Answer/Step-by-step explanation:

4x - 7 = -2x + 12 (Given)

Add 2x to both sides

4x - 7 + 2x = -2x + 12 + 2x (Addition property of equality)

6x - 7 = 12 (Simplication)

Add 7 to both sides

6x - 7 + 7 = 12 + 7 (Addition property of equality)

6x = 19 (Simplification)

Divide both sides by 6

$\frac{6x}{6} = \frac{19}{6}$ (Division property of equality)

$x = \frac{19}{6}$

Please help me with #16 I am really bad at doing fractions

emmasim [6.3K]

To see if it's a right triangle we need to determine if a²+b²=c²
( $\frac{3}{20}$ )² + ( $\frac{1}{5}$ )² = $\frac{1}{4}$
$\frac{9}{400}$ + $\frac{1}{25}$ = $\frac{1}{16}$
$\frac{9}{400}$ + $\frac{16}{400}$ = $\frac{25}{400}$
$\frac{25}{400}$ = $\frac{25}{400}$

So it is a right triangle
