Answer:

11 cm

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( where s is the side length )

Here A = 121 , then

s² = 121 ( take the square root of both sides )

s = \sqrt{121} = 11

The radius of circle O is 28, and OC =9. What is the length of AB?
aksik [14]
The answer:
the complement of the question proposed one of the choices given beneath:
a) 58.8
b) 53.0
c) 29.4
d) 26.5

as we observe at the figure, AOB an isosceles triangle, and OCB is a right triangle

consider OCB
OC =9, OB= radius = 28
the problem is how to find the length of CA, for that C is a midpoint of segment AB, so AC=BC

BC can be found by using pythagorean theorem
OB²= OC² + CB²,  this implies CB² = OB² - OC²

CB² = 28² - 9² = 784 - 81=703, therefore CB= sqrt (703)=26.51

CB=26.51, since CB= AC, so  AC=CB= 26.51

finally the <span>the length of AB is AB = 2 x CB = 2x AC= 2x 26.51= 53.0
</span>
the answer is b) 53.0

Nicole has nine dollars to spend on cards she finds friends with the same amount of money to split the cost of a set once it cos
anyanavicka [17]

Answer:

Each Friend will get \frac{x}{3} cards.

Step-by-step explanation:

Let the number of cards be x.

Given:

Amount Nicole used to spend on cards = $9

Total cost of one set =$27

Also, she finds friends with the same amount of money to split the cost of a set.

So, Number of friends she finds can be calculated by dividing the Cost of 1 set  with amount of money Nichole used to spend on cards.

Number of friends she finds = \frac{27}{9} = 3

Hence she finds 2 friends and 1 is nichole hence there are 3 persons carrying $9 to buy $27 set of card

Now, Number of cards each friend gets is equal to Total number of Cards in 1 set divided by number of people.

Number of cards each friend = \frac{x}{3}

Hence Each Friend will get \frac{x}{3} cards.
