Answer:
3000
Step-by-step explanation:
Answer:
The arc length is 87.5 inches.
Step-by-step explanation:
Given that,
Arc length = S = ?
Angle = theta = 100°
Radius = r = 50 inches
The relation between the arc length (S), angle (theta) and radius (r) is calculated using 
However, the angle should be in radian.
To convert degrees into radian, we use: 
=> 
=> 1.75 radian
By putting values in the above relation, we get


Therefore, the arc length is 87.5 inches.
Answer:
a) 90°
b) 56°
Step-by-step explanation:
If we connect O with B to get two isosceles triangles: ΔAOB and ΔBOC
∠BOC= is central angle ans is twice as ∠BAC, so equals to 2*34°= 68°
Then ∠BCA= (180°- 68°)/2= 56°
∠ABC= ∠ABO+∠CBO= 34°+56°= 90°
Answer:
dresses
Step-by-step explanation:
We are given that
Lucy sews dress in 3/4 hours=
of dress
Lucy sews at constant rate.
We have to find the number of dresses sewed by Lucy in hour.
To find number of dress sewed by Lucy in 1 hour we will use unitary method.
By using unitary method
Lucy sews in 3/4 hours=
dress
Lucy sews in 1 hour=
Lucy sews in 1 hour=
Lucy sews in 1 hour=
dresses
Hence, Lucy sews
dresses in 1 hour.
