Three line segments have measures of 18, 12, and 10. Will the segments form a triangle? a Yes, because the sum of any two side lengths is less than the length of the third. b No, because the sum of 12 and 10 is greater than 18. c No, because the sum of 18 and 10 is not less than 12. d Yes, because the sum of any two side lengths is greater than the length of the third.

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
