The answer is f(x)‐¹=(+/-)x+25+5
Answer:
7/3 is constant of proportionality and, 3/7 of a cup of red paint should be added to 1 cup of white paint.
Step-by-step explanation:
Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.
To make color pink,
for every 3 cups of red , we need 7 cups of white.
Let 'r' be the cups of red required
let 'w' be the cups of white required
so , as per the question
for 3 r we need = 7 w
r = 7/3 w
so, 7/3 is constant of proportionality and, 3/7 of a cup of red paint should be added to 1 cup of white paint.
You already have the answer! ;)
Answer:
Step-by-step explanation:
Area of the sector is modeled by the expression = 
Here, θ = central angle subtended by the arc
r = Radius of the circle
Area of the red sector = 
= 937.311
≈ 937.31 m²
Therefore, area of the red sector is 937.31 m².
