Simple:
340 copies every 8 minutes
Find copies per minute
340 / 8 = 42.5 copies/min
Now, to find out how long it took to print all 850 copies;
850 / 42.5 = 20 min.
It took 20 minutes.
Or
(850*8) / 340 = 20

5. Michael wants to place grass on the sides of his
Elden [556K]

Area of the shaded region to be covered with grass is 204 yd²

Step-by-step explanation:

  • Step 1: Area of the shaded region can be found by finding the total area and subtracting the area of the lap pool.

Total area = Area of the trapezium = 1/2 × (Sum of parallel sides) × distance between them

Sum of parallel sides = 25 yd + (3 + 12) = 40 yd

Distance between them = 12 yd

⇒ Total area = 1/2 × 40 × 12 = 240 yd²

  • Step 2: Find the area of the lap pool.

Area = length × width = 12 × 3 = 36 yd²

  • Step 3: Find the area of the shaded region

Area to be covered with grass = 240 - 36 = 204 yd²
