Answer:
to what?
Step-by-step explanation:
Given:
First customer bought 1/2 of all eggs of lady seller and 1/2 of an egg.
Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg.
At this point she had sold all her eggs.
To find:
The number of egg the lady have when she came to the market.
Solution:
Let x be the number of egg that the lady have when she came to the market.
First customer bought 1/2 of all eggs of lady seller and 1/2 of an egg. So, the number of remaining eggs after first customer is

Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg. So, the number of remining egg after second customer is





At this point she had sold all her eggs. It means the remining eggs is 0.


Multiply both sides by 4.

Therefore, the lady came to the market is with 3 eggs.
Answer:
13
Step-by-step explanation:
The formula is a^2+b^2=c^2
A and B are the lines that make up the right angle, so 5 and 12
5^2+12^2=c^2
25+144=c^2
169=c^2
Once you arrived here you square root whatever is equal to c^2
c=13
Step-by-step explanation:
applying the distance formula,
±√(0-5)^2 + (-3-0)^2 = ±√34 (rej -√34 since distance > 0)

Answer:

Step-by-step explanation:
Given:
m ∠BDC = 20
m arc AB = 140
m arc CD = 120
Now, let the center of the circle be at point 'O'.
From the triangle AOB,
OA = OB (Radius of the circle)
∴ m∠ABO = m∠BAO = m ∠1
∵ m arc AB = 140
∴ m ∠AOB = 140 (Arc measure equals the angle subtended by the arc at the center)
Now, sum of all angles of a triangle is equal to 180. So,

Therefore, the measure of angle 1 is 20. So, the last option is correct.
