The length of arc JL is 24.46 units see attachment for diagram.
<h3>What is an arc?</h3>
An arc is a part of the circumference of a circle that meets two radii of a circle to form a sector.
Analysis:
From bigger triangle, if we bisect 144, the line meets JL at 90°.
To find AL,
sin 72 = AL/6
AL = 6 sin 72 = 5.71
To find the angle at O
∠O = 2∠K ( twice angle at circumference is equal to angle at center)
∠O = 2 (144) = 288°
For smaller right-angled triangle,
sin 144 = AL/OL
sin 144 = 5.71/OL
OL = radius of circle = 5.71/0.587 = 9.73 unit
length of arc JL = ∅/360 x 2πr
= 144/360 x 2 x 3.142 x 9.73 = 24.46 units
In conclusion, the length of arc JL is 24.46 units

<span>To change an improper fraction to a mixed number you divide</span>
<span /><span>44 ÷ 24 = 1 20/24</span>
<span /><span>now to reduce find the GCF (greatest common factor) of 20 and 24</span>
<span>Factors of 20 are:
1, 2, 4, 5, 10, 20
</span>
<span>Factors of 24 are:

Answer:
C
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
Here (h, k) = (- 1, 2) and r = 3, thus
(x - (- 1))² + (y - 2)² = 3², that is
(x + 1)² + (y - 2)² = 9

625 eggs are sold in a restaurant
2500-100%
x- 25%
62500=100x
x=625 eggs
