Round 248.739 to the nearest hundred.

dick and Pam are paid \( \$ 61.75 \) for their work. Nick worked 3.5 hours, and Pam worked 3 hours. They split the money Nick and Pam are paid \( \$ \square \) for each hour worked the amount of time each of them worked. How much is Nick's share of the money? Explain.

Halle el volumen del sólido que se genera al rotar la región limitada por \( y=\sqrt{x}, y=2-x, 0 \leq x \leq 1 \) y el eje \( y \) alrededor de la recta \( y=-1 \)

Each angle of an equilateral triangle is \( 60^{\circ} \). True False

\( \left. \begin{array} { l } { \frac { 3 } { 4 } - \frac { 2 } { 5 } = \frac { ( 5 ) ( 3 ) } { ( 5 ) ( 4 ) } - \frac { ( 4 ) ( 2 ) } { ( 4 ) ( 5 ) } = \frac { 15 } { 20 } - \frac { 8 } { 20 } = \frac { - } { 20 } } \\ { \frac { 1 } { 4 } + \frac { 1 } { 2 } = \frac { 1 } { 4 } + \frac { ( L ) ( 1 ) } { ( - ) ( 2 ) } = \frac { 1 } { 4 } + \frac { 2 } { 4 } = - } \end{array} \right. \)
