Last year, 85% of students participated in the school fundraiser. Using this data, what would be the BEST prediction of how many of the 320 students will participate in the fundraiser this year?

For the function, f(x) = -5x 2, find f(-4).

This is the number of parts out of 100, the numerator of a fraction where the denominator is 100. submit

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
