ASAP NEED HELP PLEASE. In an experiment, students were given an unknown mineral. The unknown mineral was placed in 100 mL of water. Once in the water, the volume went up to 165 mL. Then when the same object was dried, then massed on a balance. It had a mass of 292.5 grams. What is the density of the unknown mineral?

Note: You only have to fill in the numerical answer. (no units)

Given: △abc, ab=15, bd=9 ad ⊥ bc , m∠c=30°. find: the perimeter of the triangle.

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.

Vertical angles must check all that apply
