If 6a=5b, what are the following ratios?
a: b

6:5

Step-by-step explanation:

6:a 5:b are equal so they ar both

6:6 5:5 are also equal

a=6

b=5

a:b equals 6:5 I think

a. 900 = 5x+w

b. Grazing area = xw

w=900-5x

Substituting w in for the first equation:

x(900-5x)=Grazing area

-5x^2+900x=Grazing area

c. We want to find the maximum possible value of -5x^2+900x. We can find the vertex of this function by using -b/2a, where b is the 2nd term and a is the first term:

-900/(2*-5)=-900/-10=90

Now, plug 90 back into the equation:

90(900-450)

That means the maximum value of x is 90 meters, and the maximum value of y is 450 meters.

Now, the total area is 90*450=40500 square meters.
