Step-by-step explanation:
Density (g/cm cubed) = Mass (g) / Volume (cm cubed)
So:
Density = 200g / 20cm cubed
Density = 10g/cm cubed
Answer:
B) 1 8/27
Step-by-step explanation:
First, change all mixed fractions into improper fractions:
2 1/3 = 7/3
1 4/5 = 9/5
7/3 ÷ 9/5
Next, flip the second fraction, and change the division sign into multiplication:
7/3 x 5/9
Multiply across:
7/3 x 5/9 = 35/27
Change into a mixed fraction:
35/27 = 27/27 + 8/27
1 8/27 is your answer.

Solving for the midpoint can be done by looking for the average of each of the given x-coordinates and y-coordinates. The 2 obtained averages are the new x-coordinate and y-coordinate. This shown below:
Midpoint = ( (-2 + 4)/2 , (5 + -9)/2 )
Midpoint = (1,-2)
Therefore, the new midpoint is (1,-2)
