The price of tiling a room varies directly as the size of the room. Sam is laying tile in his kitchen. If the tiling costs $4,22

stiv31 [10]

Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Let the price of the room be p

Let the size of the room be s

To find the size of a kitchen that costs $3,824.00 we must first find the relationship between them

The statement

The price of tiling a room varies directly as the size of the room is written as

where k is the constant of proportionality

when

p = $4,224.00

s = 264 square feet

Substitute the values into the expression to find k

That's

4224 = 264k

Divide both sides by 264

k = 16

So the formula for the variation is

when

p = 3824

$s = \frac{p}{16}$

$s = \frac{3824}{16}$

s = 239

The final answer is

239 square feet

Hope this helps you

What are the values of a1 and r of the geometric series?

tester [92]

Answer:

r = 1/3

= 1

Step-by-step explanation:

1 + 1/3 + 1/9 + 1/27 + 1/ 81

In this series a is the first term = 1

r is the common ratio = 2nd term/1st term = 3rd term/ 2nd term

r = 1/3 ÷ 1 = 1/9 ÷ 1/3

r = 1/3
