Answer:

  D.  p ≤ 24

Step-by-step explanation:

The area of a piece of paper is 8.5·11 = 93.5 square inches, so the area of the bulletin board is that of ...

  1728/93.5 ≈ 18.48

pieces of paper.

The solution is a number greater than 18, so selection D is the only viable choice.

___

The bulletin board is 24 inches high and 1728/24 = 72 inches wide. If Mrs. Wickowitz hangs the papers "sideways", then 3 of them will cover 25.5 inches vertically, and 7 of them will cover 77 inches horizontally. That's 3·7 = 21 whole sheets of paper. That, too, matches selection D.

RoseWind [281]

Answer: 84.09%


Step-by-step explanation:

1. 220-30=? ?=185

2. Divide 185 by 220 (as a fraction, 185 out of 220 is 185/220 which also means divide) 185 divided by 220 is about 0.8409

3. Multiply 0.8409 by 100 (since there is two zeros in 100 we can move the decimal to the right twice which gets you 84.09

The length of a rectangle is 3 times longer than its width. If the area of the rectangle is 24 square inches, then what is the p
NikAS [45]

Answer:  The answer is 16√2 cm.


Step-by-step explanation:  Given that there is a rectangle with length 3 times than its width. We are to find the perimeter of the rectangle.

Let 'w' represents the width of the rectangle.

Then, its length will be 3w.

Also, area of the rectangle = 24 square inches.

Therefore,

3w\times w=24\\\\\Rightarrow 3w^2=24\\\\\Rightarrow w^2=8\\\\\Rightarrow w=2\sqrt 2.

So, width = 2√2 inches and length = 6√2 inches.

Thus, perimeter of the rectangle = 4√2 + 12√2 = 16√2 cm.
