A new sidewalk will be 5 feet wide, 100 feet long, and filled to a depth of 3 inches (0.25 foot) with concrete. How many cub

GarryVolchara [31]

Answer:

4.63 cubic yard.

Step-by-step explanation:

Given,

The length of sidewalk, l = 100 feet,

Width, w = 5 feet,

Depth, h = 3 inches = 0.25 feet,

Thus, the volume of the concrete needed for making the sidewalk,

$V=l\times w\times h$

$=100\times 5\times 0.25$

= 125 cubic feet,

∵ 1 cubic yard = 27 cubic feet,

⇒ 1 cubic feet = $\frac{1}{27}$ cubic yard,

Thus, the quantity of concrete needed = $\frac{125}{27}$ ≈ 4.63 cubic yard.

Svetradugi [14.3K]

Answer:

$f(x) = \frac{Px}{100}$

Step-by-step explanation:

Let P% of the transaction amount is charged in the account.

So, if the transaction amount is x, then the charge for that transaction will be

$\frac{ Px }{ 100 }$ .

Therefore, if f(x) represents the amount Isabel is charged for the transaction then we can write $f(x) = \frac{ Px }{ 100 }$ , where P% is the rate of charge. ( Answer )
