Answer: 27 days

Step-by-step explanation: First, it's important to understand that there are 30 days in the month of september so what the problem is really asking us to do is to find out what is 90% of 30.

To find 90% of 30, first write 90% as a decimal by moving the decimal point two places to the left to get .90.

Next, the word "of" means multiply, so we have (.90)(30) which is 27.

This means that 27 days out of 30 days in September were sunny.

27 days in September were sunny because 30 x 90/100 = 27

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

Masteriza [31]

There is 1000 milliliters in a liter. So we're gonna work with thirds. One third is already filled, so that means two thirds is not . So 4 liters fills up 2/3 which we can infer that 2 liters fills up one third of the area... so there is 6 liters in total. Which means there is a total of 6000 milliliters of paint.
