Answer:

4.5 cm.  

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

\text{Circumference of a circle}=2\pi r

Upon substituting the measure of circumference in above formula we will get,

28.3=2\pi r  

r=\frac{28.3}{2\pi}

r=4.504084889500638\approx 4.5

Therefore, the radius of circle O is 4.5 cm.

professor190 [17]

Answer:

(2001, 2125),    (2006, 2360)

Step-by-step explanation:

An ordered pair refers to a pair of numbers or items in a simple and orderly manner. The order in which the items are grouped is very important. In graphs an ordered pair could be the coordinates of various points on the graph in terms of x and y, that is x and y coordinate (x,y).

From the question we are to form two ordered pair in the form (year, number of heart transplants).

to do this we simply fill out the items with their corresponding numbers where the first item is the year and second is the number of heart transplants.

in year 2001 we have   (2001, 2125)

in year 2006 we have (2006, 2360)

Aishas mother is five times older than aisha.the sum of their ages is 30.how old is aisha?
Cloud [144]

m = 5a

m + a = 30

Because we already know the value of m, we can find the value of a.

5a + a = 30

<em><u>Combine like terms.</u></em>

6a = 30

<em><u>Divide both sides by 6</u></em>

a = 5

Now that we know the value of a, we can find the true value of m.

m = 5a

m = 5 * 5

m = 25

Aisha is 5 years old, and Aisha's mother is 25 years old. (This is your answer.)
