The area of a circular table cloth is 1,384.74 inches square. Using 3.14 for LaTeX: \pi
leonid [27]

Answer:

radius = 21

circumference = 138.88

Step-by-step explanation:

First divide the area by 3.14, this equal 441

441 is your radius squared.

Then you have to find the root of 441 which is 21.

radius = 21

diameter = twice the radius or 2 * radius

diameter = 21 * 2 = 42

diameter = 42

Then plug 42 in your circumference formula.

Which is then C = 3.14(42).

Which means the circumference is 131.88.

Biologists have found that the number of chirps some types of cricket make per minute depends upon the temperature this relation
Alex Ar [27]

Answer: Crickets make 172 chirps/min at 80 degrees Fahrenheit

Step-by-step explanation:

Step 1

Using the point slope formulae for Linear functions , we have that

y - y1 = m(x - x1)

where x  and y are two points  representing the  temperature and chirps /min respectively

And  

m= slope

Step 2 : Finding the slope , m

where x1=60

           y1=92

           x2= 75

           y2=152

m= (y2-y1)/ (x2-x1)

= (152- 92)/(75-60)

=60/15 =4

Bringing down the point/slope formula and imputing the known values to find our equation to show the relationship cricket make per minute and  the temperature

y - y1 = m(x - x1)

y - 92= 4(x - 60)

y - 92 = 4x -240

y = 4x - 240 + 92

y = 4x - 148

Step 3

To find the number of chirps be per minute (y) if the temperature is 80 degrees Fahrenheit( x)

y = 4(80) - 160

y = 320 - 148

y = 172 chirps/min at 80 degrees Fahrenheit
