Answer:
The age of Mr. Collins is 30 years and
The model which represent the problem is, The age of Mr. Collins is 3 × 10
Step-by-step explanation:
Given as :
The age of Adam = 10 years
The age of Mr. Collins = x years
The age of Mr. Collins = 3 times the age of Adam
Or, x = 3 × The age of Adam
Or, x = 3 × 10
∴ x = 30
So, The age of Mr. Collins = x years = 30 years
The model which represent the problem is, The age of Mr. Collins = 3 × 10
Hence The age of Mr. Collins is 30 years and
The model which represent the problem is, The age of Mr. Collins = 3 × 10

Answer:
0.314 gallon is required to cover a circular region with a radius of 40 feet
Step-by-step explanation:
Given
a gallon of paint will cover about 400 square feet in a single coat
To Find:
Number of gallons required to cover a circular region with a radius of 40 feet = ?
Solution:
Step 1: Finding Area of the circular region
The area of the circular region, A = ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
where r is the radius
Now substituting r = 40 , we get
A = ![\pi \times 40](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%2040)
![A = 125.6 ft^2](https://tex.z-dn.net/?f=A%20%3D%20125.6%20ft%5E2)
Step 2: Finding the number of gallons of paint required
To cover 400 sq feet = 1 gallon
so to cover 1 square feet =
gallon
Now to cover 125.6 ft we need
![125.6 \times \frac{1}{400}](https://tex.z-dn.net/?f=125.6%20%5Ctimes%20%5Cfrac%7B1%7D%7B400%7D)
![\frac{125.6}{400}](https://tex.z-dn.net/?f=%20%5Cfrac%7B125.6%7D%7B400%7D)
=> 0.314 gallon
