The Magic Carpet charges $90 for installation and $9 per square yard of carpeting. If the total cost to carpet an office is $810
, how many square feet is the office?
1 answer:
Answer:
<h2>
11.11 square yard </h2>
Step-by-step explanation:
Step one:
given data
charges=$90
installation=$9 per square yard
total cost of installation= $810
let x represents the number of square feet
Step two:
The expression for the installation cost is given as
810=9x+90------------1
solve for x, collect like terms
810-90=9x
720=9x
divide both sides by 9 we have
x=720/9
x=11.11 square yard

<u>Answer</u>
320 cm³
<u>Explanation</u>
Firstly, find the constant of proportionality.
V ∝ 1/p
V = k/p Where V= volume, k = constant and p = pressure of the gas.
1600 = k/4
k = 1600 × 4
= 6,400
The equation will be,
V = 6,400/p
For p =20 Kg/cm²,
V = 6,400/20
= 320 cm³
