Answer:
= −14/5
Step-by-step explanation:
= − 14/5 cause that's what I think it is also I solved it and this is what I got
there are 360 degrees in a complete circle
360/18 = 20
so the answer is C
Answer:
Best to draw out a factor tree.
The displaced volume of the water, because of the submersion of the object, is equal to the volume of the object.
So to find the volume of the object we calculate the difference in volume of water:
33.1-25.1 = 8 ml
Since 1 mL of water has the volume of 1cm^3, then the volume of the object is 8 cm^3.
The density of the object is found by the formula:
density= mass/volume= (3 g) / (8 cm^3) = 3/8 (g/cm^3)= 0.375 g/cm^3
Answer: 0.375 g/cm^3
