Radius = diameter x 0.5
0.5x0.5 = 0.25meter
0.25 meter x 100 cm (100cm in one meter) = 25cm
also for future reference circumference = pie x r squared.
Do you have the answer choices?
8 goes with 3/5: 10 goes with n (n being the number of cups)

Use cross products and we get 8n = 6
Now divide by 8
<u>8n</u> = <u>6
</u><u />8 8
n= 6/8 or 3/4 of a cup of flour.
There is only one solution in the given equation -y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0. In solving this problem, apply first PEMDAS (parenthesis, exponents,multiplication, division, addition, subtraction). Then equation will transform into -y2+5y-7y2-9y+15y2+4y=0. Combine terms with same power and achieve 7y2=0. Divide both sides with 7 and perform square root of zero. Since the root is zero, we have one solution of the given equation which is y=0.
