Answer:
2%
Step-by-step explanation:
x is percentage (%)
490+(490*x)= 499.80
490*x=9.80
x=9.80/490
x=2/100
x=2%
Find the average of the two fractions: 14/20 + 15/20= 29/20 then divide that by 2 and get 29/40
Check: 14/20= 28/40 and 15/20= 30/40 between 28 and 40 is 29
Ans: 29/40
Answer:
∠ DEB = 101.97°
Step-by-step explanation:
BCDE is a cyclic quadrilateral, whose opposite angles are supplementary, so
∠ BCD + ∠ DEB = 180°, that is
78.03° + ∠ DEB = 180° ( subtract 78.03° from both sides )
∠ DEB = 101.97°
Answer:
69.6 ft
Step-by-step explanation:
The arc length can be found as a fraction of the circumference. That fraction is the ratio of the central angle measure to the measure for the whole circle.
__
Central angle of remaining arc:
360° -150° = 210°
Fraction of full circumference:
210°/360° = 7/12
The circumference of the circle is ...
C = 2πr = 2π(19 ft) = 38π ft.
Then the length of the remaining arc is ...
(7/12)(38π) ft ≈ 69.6 ft
