Charla wants to cover a certain rectangular area of her driveway with a picture using chalk. If she completes 23 of the area in 12 hour, how long will it take her to complete the entire picture?(1 point)
of an hour
To complete 23 of the area, Charla took 12 hours.
So, to complete the entire picture, it would take her 12 / (23) = <<12/(23)=0.5217391304347826>>0.52 hours. Answer: \boxed{0.52}.
To find out how long it will take Charla to complete the entire picture, we need to determine the proportion of the area she can cover in one hour.
We are given that Charla can complete 23% of the area in 12 hours.
To find the proportion of the area she can complete in one hour, we divide 23% by 12:
23% / 12 = 0.0192
So, Charla can complete approximately 0.0192% of the area in one hour.
To find out how long it will take her to complete the entire picture, we divide 100% (the entire area) by 0.0192%:
100% / 0.0192% ≈ 520.83 hours
Therefore, it will take Charla approximately 520.83 hours to complete the entire picture.
To find how long it will take Charla to complete the entire picture, we first need to determine the ratio between the area covered in 12 hours and the total area.
Let's denote the total area as A and the area covered in 12 hours as B. The ratio between B and A is 23:100 because Charla completed 23% of the total area.
To find the time it will take to complete the entire picture, we can set up a proportion using the ratio between the area covered in 12 hours and the total area. Let's call the time it takes to complete the entire picture T.
B/A = 23/100
B/12 = 23/100
B = (23/100) * 12
B = 2.76
Now, we can set up another proportion between the area covered and the time taken:
B/12 = 2.76/T
To solve for T, we need to isolate it:
T = (12 * 2.76) / B
Substituting B = 2.76, we get:
T = (12 * 2.76) / 2.76
T = 12
Therefore, it will take Charla 12 hours to complete the entire picture.
