Answer:
a) Constant of proportionality = 0.25
b) The constant of proportionality provides the cost of one apple.
c) n = 12
Step-by-step explanation:
It is given that:
c = 0.25n
a) Here,
c = cost of apples
n = number of apples
As the proportion varies directly.
c ∝ n
c = kn
Comparing the equations
k = 0.25
b) The constant of proportionality provides the cost of one apple.
c) Putting c = $3
3 = 0.25n
Dividing both sides by 0.25
n = 12
Thus,
a) Constant of proportionality = 0.25
b) The constant of proportionality provides the cost of one apple.
c) n = 12
5x10-27=$23
5 = amount of bills, 10= dollar bills, 27= cost of toy, 23= cost leftover
Answer:
Semicircle = 353.25 cm²
Step-by-step explanation:
Area of semicircle = πr²/2
substitute the values
semi circle = 3.14 × 15 × 15 / 2
Area of semicircle = 353.25 cm²
The right answer is Option D.
Step-by-step explanation:
Given,
Radius of basketball hoop = 9 inches
As the basketball hoop is in circular shape.
Circumference of basketball hoop = 2πr
We will put given radius = 9
Circumference of basketball hoop = 2*π*9
Circumference of basketball hoop = 2 . 9 . π
Therefore,
Circumference of basketball hoop is 2*9*π.
The right answer is Option D.
