Estimate the answer by rounding each number to one nonzero digit first, then perform the actual calculation. One year in a certain town the yearly rainfall totaled 11.67 melers. The next year, the yearly rainfall in the town totaled 13.06 meters. The third year it was 11.84 meters. On average, how much rain fell in the town per year? Find the estimated value. On average, about \( \square \) moters of rain fell in the town per year.

For the following equation, a. Write the value or values of the variable that make a denominator zel in mind, solve the equation. \( \frac{2}{5 x}+\frac{1}{4}=\frac{74}{10 x}-\frac{1}{3} \) a.

Find the angular speed \( \omega \) for the following. a wind turbine with blades turning at a rate of 11 revolutions per minute The angular speed for a wind turbine with blades turning at a rate of 11 revolutions per minute is (Simplify your answer. Type an exact answer, using \( \pi \) as needed. Use integers or fractions for any

Subtract: \( \left(4 b^{2}-8 b+11\right)-\left(-2 b^{2}-4 b+5\right) \) \( 2 b^{2}-12 b+16 \) \( 2 b^{2}-12 b+6 \) \( 6 b^{2}-12 b+6 \) \( 6 b^{2}-4 b+6 \)

Solve for \( y: 3(2 y+4)=4\left(2 y-\frac{1}{2}\right) \). The solution is \( y= \) The solution is
