Answer:
<h3>28feet</h3>
Step-by-step explanation:
Let the wallpaper be a rectangle
Area of a rectangle = Length * Width
A = LW
Perimeter P = 2L+2W
If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.
60 = 2L + 2(2)
60 = 2L + 4
2L = 60-4
2L = 56
L = 56/2
L = 28
<em>The minimum length that will be purchased to cover the wall is 28 feet</em>
Answer:
Associative Property of Multiplication
Step-by-step explanation:
We are given three numbers-a,b,c.
We are given the property (ab)c = a(bc)
This implies that on the left hand side we first multiply a and b and then multiply the result by c. On the right side of the equation, we first multiply b and c and multiply a with the product of b and c.
As per the given property, the result in both the cases is the same.
This signifies the associative property of multiplication where the result is independent of the order of operation.
Answer:
12,000 Litres
Step-by-step explanation:
The tank is rectangular with given dimensions.
<em>The quantity of oil is the volume of oil given by:</em>
Volume of Oil = length * width * height of oil (depth)
Hence,
Volume of oil = 5 * 2 * 1.2 = 12 cubic meters
<em>Since 1 cubic meters = 1000 liters, we have:</em>
12 (1000 Liters) = 12,000 Liters
