Answer:
D. 29
Step-by-step explanation:
∠ACE is a secant- secant angle and is measured as half the difference of the intersecting arcs, that is
∠ACE = 0.5(m AE - m BD )
= 0.5 (106 - 48)° = 0.5 × 58° = 29° → D
Answer:
32. <u>40%</u>
33. <u>15%</u>
34. <u>1/5</u>
35. <u>1/4</u>
Step-by-step explanation:
<u>Question 32</u>
- % Hens = No. of hens / Total poultry
- % Hens = 72 / 27 + 72 + 45 + 36
- % Hens = 72 / 180 = 2/5
- % Hens = <u>40%</u>
<u>Question 33</u>
- % Geese = No. of geese / Total
- % Geese = 27/180
- % Geese = 3/20
- % Geese = <u>15%</u>
<u>Question 34</u>
- % Ducks = No. of ducks / Total
- % Ducks = 36/180
- % Ducks = <u>1/5</u>
<u>Question 35</u>
- % Turkeys = No. of turkeys / Total
- % Turkeys = 45/180
- % Turkeys = <u>1/4</u>
Answer:
the first one
the first one Step-by-step explanation:
the first one Step-by-step explanation:from the formula Un =ar^n-1
where a is 2
where a is 2 r = 20/2=10
where a is 2 r = 20/2=10 so Un= 10×2^n-1
that's all.....have fun
