algol [13]

Use compound interest formula

$\\ \rm\Rrightarrow P(1+r/100)^t=500$

$\\ \rm\Rrightarrow 100(1+0.25)^t=500$

$\\ \rm\Rrightarrow (1.25)^t=5$

$\\ \rm\Rrightarrow log(1.25)^t=log5$

$\\ \rm\Rrightarrow tlog1.25=log5$

$\\ \rm\Rrightarrow t(0.097)=0.3$

$\\ \rm\Rrightarrow t=3.3\approx 3$

Need to know what the value of x is

Mnenie [13.5K]

Answer:

$x=15$

Step-by-step explanation:

Use the Pythagorean Theorem

$a^2-b^2=c^2$

With c being the hypotenuse, or x in this case

$9^2+12^2=x^2$

$81+144=x^2$

$225=x^2$

Now take the square root of 225

$\sqrt{225}=x$

$\sqrt{225}=15$

$x=15$
