Answer:
0.865
Step-by-step explanation:
Specific gravity is a ratio of the weight of a substance to the weight of an equal volume of a substance chosen as a standard. The standard for liquid and solids is water while for gas is hydrogen.
Amount of displaced oil = 12.64 g — 9.12 g = 3.52 g
Amount of displaced water = 12.64 g — 8.57 g = 4.07 g
Specific gravity of oil = 3.52 g / 4.07 g = 0.865
Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar we can find x using similarity ratio
14/8 = (x+6)/(x-3) simplify first expression
7/4 = (x+6)/(x-3) cross multiply expressions
7×(x-3) = 4×(x+6)
7x-21 = 4x + 24 add like terms
3x = 45
x = 15
