Step-by-step explanation:
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
Y=x+2
The slope is 1. You are supposed to always pretend that an imaginary 1 is in front of any variables
Answer:
3.√
4.√
Step-by-step explanation:
similar rectangles have proportional sides so compare corresponding sides to check
1. 169/1.3 = 49/0.7 → 130 ≠70 no
2. 18.55/5.3 = 10.5/3.5 → 3.5 ≠ 3 no
3. 120/24 = 60/12 → 5 = 5 yes
4. 189/2.1 = 81/0.9 → 90 = 90 yes
2/3 + 3/5m = 31/15
3/5m = 31/15 - 2/3
3/5m = 31/15 - 10/15
3/5m = 7/5
m = 7/5 * 5/3
m = 35/15 reduces to 7/3 or 2 1/3
-3c - 12 = -5 + c
-3c - c = -5 + 12
-4c = 7
c = -7/4 or - 1 3/4
