Answer: It would take 9 hours for 4 painters to paint 720 feet of fence.
Step-by-step explanation:
1.) Calculate the time needed to paint the 720 ft fence with 2 painters.
a.) Divide 720 by 280 to get how many times greater 720 is than 280.
720 / 280 ≈ 2.57
b.) Multiply the time needed to paint the 280 ft fence with 2 painters by 2.57.
7 * 2.57 ≈ 18
2.) Calculate the time needed to paint the 720 ft fence with 4 painters.
a.) Assuming that each painter paints the same amount of fence, divide the time in half, as 4 painters is double the original amount, so it would take half of the time.
18 / 2 = 9
Answer:
x=6
Step-by-step explanation:
5x = 30
30 - 2 = 28
6x= 36
36 - 8 = 28
28 = 28
Answer:
∠A = 45°
Step-by-step explanation:
◺ABC is a right angled triangle.
Sum of interior angles in a triangles is 180.
∠A + ∠B + ∠C = 180°
∠A + 90° + 45° = 180°
∠A = ( 180 - 90 - 45 )°
∠A = 45°
Note : -
□ is 90°
