A website uses the formula above to calculate a seller’s rating, R, based on the number of favorable reviews, F, and unfavorable
reviews, N. Which of the following expresses the number of favorable reviews in terms of the other variables?
F=RN/R-1
F=RN/1-R
F=N/1−R
F=N/R−1
1 answer:
The correct formula is
RN/(1-R) = F.
To solve for F, we start by multiplying by (N+F) to remove it from the denominator:
R(N+F) = F
Distributing, we have:
RN + RF = F
Subtracting RF to collect all of the F's on one side,
RN = F - RF
Factoring out F on the right hand side,
RN = F(1 - R)
Dividing both sides by (1-R),
RN/(1-R) = F

The Solution.
The given equation is
Substituting 11 for x, we can get the value of y.
Hence, the value of y is 18.
You multiply 3.14 by the diameter or 2 times the radius
for area you do pi or 3.14*radius squared
Answer:
A=50.26548246units^2
Step-by-step explanation:
Radius is 4 because half the diameter (8) is the radius (4)
A=πr^2
A=π(4)^2
A=50.26548246units^2
Let
x--------> the number of gray bricks
y--------> the number of red bricks
we know that
------> inequality 1
<em>-----> </em>inequality 2
therefore
<u>the answer is</u>
x > 0
0.45x+0.58y≤200
