Answer:
18.05
Step-by-step explanation:
0.65×3=1.95
20-1.95=18.05
The circumference of a circle is the <em>total length</em> of the <u>boundary</u> of the circle. So that the length of lace trim required is 597.1429 cm.
The <em>diameter</em> of the table is <u>60</u> cm, which has <u>65</u> cm tablecloth hanging on its sides. The diameter of the cloth required would be the <em>length</em> from <u>one</u> side to the <u>other</u> side. So that the <u>total</u> diameter of the tablecloth is:
= 60 cm + 2*65 cm
= 60 cm + 130 cm
= 190 cm
The <em>diameter</em> of the <u>tablecloth</u> required is 190 cm.
Thus to determine the <em>circumference</em> of the <u>tablecloth</u>, we have;
C = 2r
= D
where D is the <u>diameter</u> of the tablecloth.
C = x 190
= 597.1429
C = 597.1429 cm
Therefore, the length of lace trim required for the <em>edge</em> of the <u>tablecloth</u> is 597.1429 cm.

The answer should be 8x^3-36x^2+54x-27
To get this you have to do (2x-3)(2x-3)(2x-3) and distribute through each parenthesis. Hope this helps
Answer:
20 < L < 24
Step-by-step explanation:
We know that in any given triangle, the length of two sides is always greater than the length of the third side.
Since the sail is a triangle having length of one side as 22 feet and the length of another side as 2 feet, and let L be the length of the third side.
It follows from our triangle rule of sides above that
22 + 2 > L (1)
22 + L > 2 (2)and
L + 2 > 22 (3)
It follows that from (1)
22 + 2 > L
⇒ 24 > L (4)
It follows that from (2)
22 + L > 2
⇒ L > 2 - 22
⇒ L > - 44 (5) and
It follows that from (3)
L + 2 > 22
⇒ L > 22 - 2
⇒ L > 20 (6)
Since from (5) and (6),
L > -44 and L > 20
and 20 > -44 ⇒ L > 20
⇒ 20 < L (7)
From (4) 24 > L ⇒ L < 24 (8)
Combining (7) and (8), we have
20 < L < 24
So, the possible range of values of the third side are 20 < L < 24
