A thermometer shows a temperature of -20 3/4 degrees. A chemist recorded the temperature in her notebook using a decimal. Which number did the chemist write in the notebook?

(answer choices in the pic)

-20.75

Step-by-step explanation:

3/4 as a decimal is 0.75

-20 3/4 = -(20 3/4) = -(20.75) = -20.75

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
