A painter can paint 375 square feet in 3 hours. At this rate, how many square feet can he paint in 7 hours?(1 point)
If a painter can paint 375 square feet in 3 hours, then he can paint 375/3=<<375/3=125>>125 square feet in 1 hour.
Therefore, the painter can paint 125*7=<<125*7=875>>875 square feet in 7 hours. Answer: \boxed{875}.
To find out how many square feet the painter can paint in 7 hours, we can use a proportion.
Let's set up the proportion:
```
375 square feet / 3 hours = x square feet / 7 hours
```
To solve for x, we can cross-multiply:
375 square feet * 7 hours = 3 hours * x square feet
2625 square feet = 3x
Next, divide both sides of the equation by 3 to solve for x:
2625 square feet / 3 = x
x = 875 square feet
Therefore, the painter can paint 875 square feet in 7 hours.
To find out how many square feet the painter can paint in 7 hours, we need to determine the painter's painting rate per hour.
Since the painter can paint 375 square feet in 3 hours, we can calculate his painting rate per hour by dividing the total square footage by the total number of hours:
375 square feet ÷ 3 hours = 125 square feet per hour.
Now, to calculate the number of square feet the painter can paint in 7 hours, we can multiply his painting rate per hour by the total number of hours:
125 square feet per hour × 7 hours = 875 square feet.
Therefore, the painter can paint 875 square feet in 7 hours.
