Answer:
6(√2 - 5√3).
Step-by-step explanation:
3√2 ( 2 - 5 √6)
= 6√2 - 15√12
= 6√2 - 15√4√3
= 6√2 - 30√3
= 6(√2 - 5√3)
Given;
40 fluid ounces of iced tea.
We know,
1 cup = 8 fluid ounce
1 pint = 2 cup
Now,
8 fluid ounce = 1 cup
1 fluid ounce = 1 / 8 cup
40 fluid ounce = (1 / 8) * 40 cup
So, 40 fluid ounce = 5 cup
Now,
We, used 3 cups of iced tea. So, we only have 2 cups of iced tea left.
We have,
2 cups = 1 pint
So, 1 pint of iced tea is left!
The wall area is the product of the room perimeter and the room height:
A₁ = (2*(12.5 ft + 10.5 ft))*(8.0 ft) = 368 ft²
The window and door area together is
A₂ = 2*((4 ft)*(3 ft)) + (7 ft)*(3 ft) = 45 ft²
The area of one roll of wallpaper is
A₃ = (2.5 ft)*(30 ft) = 75 ft²
Then the number of rolls of wallpaper required will be
1.1*(A₁ - A₂)/A₃ ≈ 4.74
5 rolls of wallpaper should be purchased.
_____
As a practical matter, not much of the window and door area can be saved. The rolls are 30 inches wide, but the openings are 36 inches wide. Some will likely have to be cut from two strips. The strips will have to be the full length of the wall, and the amount cut likely cannot be used elsewhere. If the window and door area cannot be salvaged, then likely ceiling(5.4) = 6 rolls will be needed (still allowing 10% for matching and waste).
Think of 180 divide by 3
it’ll give you 60
so there are 60 green apples
