Answer: $11.80 for another 4 panes of glass.
Step-by-step explanation: We know that 9 panes of glass cost $26.55, but we should first find how many dollars would it cost per pane of glass, or 1.
So, we can divide 26.55 by 9 to find the price per 1 pan of glass.
26.55/9 = 2.95, or $2.95 per pane of glass.
Now, we want to know how much it will cost for 4 panes of glass. Simply multiply 2.95 by 4.
2.95 x 4 = 11.8, or $11.80 for another 4 panes of glass.
Mass = 100 g
Volume = 50 cm³
Density :
D = m / V
D = 100 / 50
D = 2 g/cm³

Answer:
13 over 22
Step-by-step explanation:
because you want to change the denominator to where they can match. So 22 is where 11 and 2 can match. then you want to multiply the amount you multiplied with the denominator so 1 over 11 would be 2 over 22. And 1 over 2 would be 11 over 22. and then you can add. 11 plus 2 is 13 and you can keep the denominator the same. Therefore, the answer would be 13 over 22
