Circle theorem:
The angle at the centre (T) is double the angle at the circumference (Q)
---> That also means that:
The angle at the circumference (Q) is <u>half</u> the angle at the centre (T)
Since T = 130 degrees;
Q = 130 divided by 2
= 65°

Answer:
∠Q = 65°
Answer: Ruth have to make 7 hats to break even.
Step-by-step explanation:
Break even point is a point where Cost = Revenue.
Let x be the number of hats sold.
Given: Cost of booth = $63
Each hat cost = $10
Selling price for each cost = $19
As per given,
Total cost = Cost of booth+ (Cost of each hat)(Number of hats)
= 63+10x
Total selling price = 19x
For break even,
63+10x=19x
9x=63
x=7
Hence, Ruth have to make 7 hats to break even.
Number of ways = 4! = 4 x 3 x 2 x 1 = 24
Answer: 24
