350kg of plastic is moulded to make garden pots weighing 1 whole 2/5 kg each. How many pots are made?​
slega [8]

The number of pots made are 250

The number of pots that can be made can be determined by dividing the total weight of the plastic by the weight of pots made

Number of pots made = Weight of plastic / weight of pot made

350 ÷ 1\frac{2}{5}

Convert the mixed fraction to an improper fraction

350 ÷ \frac{7}{5}

350 x \frac{5}{7} = 250 pots

Someone help me please!!!!!!!!!!!

You have 3 unknowns: a, b, and c.  That means you have to have 3 equations to solve for the values of them.  3 unknowns needs 3 different equations.  We will use the first 3 points in the table and thank God that one of them has an x value of 0.  We will replace the x and y in the general form of the quadratic with the x and y from the table, 3 times, to find each variable. Watch how it works. We will start with (0, 15). a(0)^2+b(0)+c=15.  That gives us right away that c = 15.  We will do the same thing again with the second value in the table along with the fact that c = 15 to get an equation in a and b.  a(2)^2+b(2)+15=15.5 which simplifies to 4a+2b=.5.  Now do the same for the third set of coordinates from the table.  a(4)^2+b(4)+15=17 which simplifies down to 16a+4b=2.  Solve those simultaneously.  Multiply the first bolded equation by -4 and then add that one to the second bolded one.  -4(4a+2b=.5) gives us -16a-8b=-2.  Add that to the second bolded equation and the a terms cancel out giving us -4b=0 so b = 0.  Subbing that back in we solve for a:  16a+4(0)=2 and 16a = 2.  Therefore, a = 1/8.  The quadratic then is \frac{1}{8}x^2+15=y
