Answer:
Down below
Step-by-step explanation:
For this case we have that the cost of each pizza is given by the following function:
Where:
r: It's the radius of the pizza
IF a pizza cost $26.32 we have:
We cleared the radius, using :
We choose the positive value:
So, the radius of the pizza is
Then, the diameter is:
Finally, the diameter of the pizza is:
Answer:
Option B
The picture in the attached figure
we know that
In similar triangles. The ratio of the lengths of the sides CS and CB must be equal to the ratio of the lengths of sides CR and CA. CS / CB = CR / CA
which can also be written as,
CS / (CS + SB) = CR / (CR + RA)
CS*(CR+RA)=CR*(CS+RA)
CS=2x+1
SB=6x
CR=7.5
RA=18
(2x+1)*[7.5+18]=7.5*[2x+1+18]
(2x+1)*[25.5]=7.5*[2x+19]
(51x+25.5)=15x+142.5
51x-15x=142.5-25.5
36x=117
x=117/36
x=3.25
the answer is
x=3.25
