Stacy is painting her bedroom. She is able to paint 3-4 of the bedroom in 3 hours. At this rate, how long will it take her to paint the entire bedroom?
To find out how long it will take Stacy to paint the entire bedroom, we need to determine how many sets of 3-4 portions of the bedroom are needed.
Let's assume that Stacy needs x sets to paint the entire bedroom.
Since she can paint 3-4 portions in 3 hours, we can say that:
3-4 portions = 3 hours
To find out how many sets of 3-4 portions are needed, we can set up a proportion:
3-4 portions / 3 hours = x sets / t hours
Where t is the time it will take Stacy to paint the entire bedroom.
Using cross-multiplication, we get:
(3-4 portions) * (t hours) = (3 hours) * (x sets)
Simplifying, we have:
3-4x = 9x
Then, combining like terms, we get:
7x = 3
Finally, solving for x:
x = 3/7
Therefore, Stacy will need to paint approximately 3/7 of the bedroom in 3 hours.
To find out how long it will take Stacy to paint the entire bedroom, we need to determine the rate at which she paints.
Stacy is able to paint 3-4 of the bedroom in 3 hours. Let's assume that the bedroom can be divided into four equal parts, and she can paint one part in 3 hours.
Therefore, we need to determine how many parts there are in the entire bedroom. If we assume the entire bedroom can be divided into four equal parts, then it would take Stacy 3 hours * 4 = 12 hours to paint the entire bedroom.
If we assume the entire bedroom can be divided into three equal parts, then it would take Stacy 3 hours * 3 = 9 hours to paint the entire bedroom.
So, depending on the assumption we make, it will take Stacy either 9 hours or 12 hours to paint the entire bedroom.
To find out how long it will take Stacy to paint the entire bedroom, we need to divide the total area of the bedroom by the area she can paint in 3 hours.
If Stacy can paint 3-4 of the bedroom in 3 hours, she can paint 1/3 to 1/4 of the bedroom in 1 hour.
Let's calculate the time it takes for Stacy to paint 1/3 of the bedroom in 1 hour:
1 hour x 3 = <<1*3=3>>3 hours
Now let's calculate the time it takes for Stacy to paint 1/4 of the bedroom in 1 hour:
1 hour x 4 = <<1*4=4>>4 hours
Since we want an estimate between 3 and 4 hours, we can say that it will take Stacy approximately 3.5 hours to paint the entire bedroom.
