We call the ratio between two directly proportional quantities the constant of proportionality. When these two quantities may increase or decrease, the constant proportionality always remains the same
Answer:
$4.80
Step-by-step explanation:
Make a proportion
$12 for 2.5 pounds, and $x for 1 pound
12/2.5=x/1
x/1 is equivalent to x
12/2.5=x
Divide
x=4.8
So, one pound of peanuts costs $4.80
Answer:
82.96
Step-by-step explanation:
area of box:
A = L^2 = (14 in.)^2 = 196 in.^2
area of pizza:
A = (pi)r^2 = 3.14 * (6 in.)^2 = 113.04 in.^2
Empty area:
196 in.^2 - 113.04 in.^2 = 82.96 in.^2
If x=3 then the f(x)=4
If x=6 then the f(x)=7
If x=7 then the f(x)=8
Answer:
12 inches
Step-by-step explanation:
180 divided by 3 = 6
so the tower is now divided into 6 pieces
each piece is 30 feet
every 30 feet is represented by 2 inches
2 times 6 = 12
