5. An empty graduated cylinder has a mass of 50 grams. The cylinder has a mass of 120
grams when 30 milliliters of water is poured in. If a rock is added to the graduated
cylinder, then water level rises to 75 milliliters and the mass is now 250 grams. Determine
the density of the rock.

Which of the following is true for the relation f(x)=2x^2+1

Olga used 100 ounces of flour to make 225 muffins. how many ounces of flour will be used to make 300 muffins?

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.
