Answer:
The width of the border can be 9 feet or 3.5 feet.
Step-by-step explanation:
Let the width be x
Length of room = 10 feet
Breadth of room = 15 feet
Length of rug = 10-2x
Breadth of rug = 15-2x
Area of rug =
We are given that the area of the rug is 24 square feet.
So, ---A
Substitute x =9 in A
LHS = RHS
Substitute x = 3.5
LHS = RHS
So, The width of the border can be 9 feet or 3.5 feet.
Answer: 15 inches
Step-by-step explanation:
Volume(V) = 40 cubic inches
Height (h) = 8 inches
1.) Volume of cone = (1/3) × base(B) × h
2.) 40 = (1/3) × base × 8
3.) 40 = (8/3) × base
4.) Multiply both sides by the reciprocal (3/8)
(40) × (3/8) = (8/3) × (3/8) × base
120/8 = base
15 = base
Therefore, base area of cone = 15 inches
It will take total 90 minutes to finish the book and 60 minutes to read the left 40 pages.
<h3>What is Ratio and Proportion ?</h3>
When two numbers can be written as p/q is called a Ratio , and when two ratios are equal they are said to be in proportion .
It is given that
Jeremy is reading a 60-page book.
The time taken to read 20 pages is 30 minutes
Then it can be written as 20:30 = 2:3
The rate of reading is same so To read the rest 40 pages is given by
40:x
40: x = 2:3
40*3/2 = x
x = 60 minutes
Therefore it will take total 90 minutes to finish the book and 60 minutes to read the left 40 pages.
