Step-by-step explanation:
Less than 2 hours. Since 100 percent of her time is 2 hours and she only spent 20 percent of 2 hours, which is less than 100 percent, it is less than
25%. You have:
100% : 260
?% : 65
-> % = (100 x 65)/260 = 25%
24 x 24 = 576
<span>24 + 24 = 48 </span>
<span>576 is equal to 24 squared. Hope i helped ;)</span>

This ODE has characteristic equation


which has roots at
. Then the characteristic solution to the ODE is
