Step-by-step explanation:
7√144 - 11√45 + 6√500
= 7(12) - 11√(9×5) + 6√(100×5)
= 84 - 11(3)√5 + 6(10)√5
= 84 - 33√5 + 60√5
= 84 + 27√5
3/5 or 60%.
2/3 hour is 40 minutes, so 1/3 is 20 minutes.
40 minutes have passed and 2/5 of the progress on the floor is complete. In 20 minutes, 1/5 of the work is complete. Add 20 minutes to 40 minutes to get 60 minutes, or an hour.
Because of this, we need to add the progress of 20 minutes and 40 minutes. 1/5+2/5=3/5.
Answer:
See below.
Step-by-step explanation:
Find the area of the rectangle using A = l*w = 26*20 = 520.
Now find the area of the semi circle using A = 1/2 πr². Since the instructions do not say the diameter of the semi circle assume it is 20 or 26.
If it is 20: r = 10 and the area is A = 1/2 π10²=50π = 157.
If it is 26: r = 13 and the area is A = 1/2π13² = (84.5)π = 265.33.
The area of the paperboard that remains will be the area of the rectangle minus the area of the semi circle.
If the diameter of the semi circle is 20 then 520 - 157 = 363.
If the diameter of the semi circle is 26 then 520 - 254.67.
