Answer: 8 1/4g/cm³
Step-by-step explanation:
Given the graph :
The rate of change in the mass of copper with respect to volume :
To obtain this, we find the slope or gradient of the graph:
Gradient = Δy / Δx = (y2 - y1) / (x2 - x1)
Drawing a right angled triangle on the anybpart of the line of best fit:
y2 = 40 ; x2 = 4.75 ; y1 = 16 ; x1 = 2
(y2 - y1) / (x2 - x1)
= (40 -16) / (4.75 - 2)
= 24 / 2.75
= 2400/275
= 8.727 g/cm^3
Due to unit and graph scale,, the slope is closest to 8 1/4g/cm³
Given:
O is the midpoint of line MN
OM = OW
To prove: OW = ON
<u>Statement</u> <u>Reason</u>
1> OM = OW -------------------------> Given
2> OM = ON ---------------------------> O is the midpoint of line MN
i.e Point O bisects line MN
3> OM = OW --------------------------> From statement <1>
4> ON = OW -------------------------> OM = ON (Statement <2>)
OW = ON
<u>proved!!</u>
Answer:
1.9 x 10=19
4.2x10=42
Now just find out how to multiply 19 -8 times and how to multiply 42, -13 times.
Step-by-step explanation:
hope this helps if not sorry
The answer to this is 17/6
decimal form: 2.83 (the three is repeating)
mix number: 2 5/6
Hope this helped :)
Adding rational numbers involves adding decimals and repeating decimals like 4.6666666..... Whole numbers on the other hand involves adding 7+6 which arent exactly decimals
