Answer:
The area of the portion of the wall that will be painted is 105 square feet
Explanation:
Total area of wall = 12 × 10 = 120 ft²
The area of the wall that will not be painted = area of the blackboard = 5 × 3 = 15 ft²
So, the area of the wall to be painted = Total area of wall - Area of the wall that will not be painted = 120 - 15 = 105 ft²
A roller coaster car starts from the rest from a first summit, descends a vertical distance of 45 meters and then climbs a second summit, reaching the top with a speed of 15m / s. How high is the second summit? Do not consider friction
