Substitute x to be 7 (for month 7) and work out the equation:
y = -13(7) + 111
y = -91 + 111
y = 20
Your answer is 20 degrees Fahrenheit.
The volume of the ethanol inside the tube can be obtained by dividing the mass of ethanol by the density. The volume is equal to 15.03 ml or 15.03 cm3. The volume of the tube is equal to pi d^2/4 * h where h is 15 cm. From this formula, the diameter is equal to 1.13 cm.
X=3
First, divide both equation sides by 4
Next, divide the values
X=3 :)
72 because 12times 4 is 48 then 3/2 times 48 and that is 144/2 then divide it and 72
