Answer:
C
Step-by-step explanation:
given that x and y are proportional then the equation relating them is
y = rx ← r is the constant of proportionality
to find r, substitute x = 3 and y = 9 into the equation
9 = 3r ( divide both sides by 3 )
3 = r
the constant of proportionality is r = 3
Answer:
$35
Step-by-step explanation:
If $21 is 60% of the original price, then the original price is ...
21 = 0.60p
21/0.60 = p = 35
The original price is $35.00.
Answer:
$35
Step-by-step explanation:
If $21 is 60% of the original price, then the original price is ...
21 = 0.60p
21/0.60 = p = 35
The original price is $35.00. , hope it helps i answered last time but was deleted
Answer:
52 left-handed players
Step-by-step explanation:
The answer is asking, how many players is 80% of 65.
"of" = multiply

Answer:
100/π cm
Step-by-step explanation:
Volume of a cylinder = πr²h
Volume = 10,000cm³
Radius = 10cm
The formula for the height of a cylinder is obtained as:
V = πr²h
h = V/ πr²
h = 10000 /π × 10²
h = 10000 /π × 100
h = 100/π cm
The height of the cylinder in terms of π = 100/π cm
