Need with math problem the temperature of a lake drops by the same amount each day for 10 days. the temperature drops by a total of 5 degrees. drag the numbers to form the equation that represents the change in the lake's temperature each day. ( ? ) ( ? ) = ( ? ) 5, -5, 10, -10, 1/2, -1/2, 1/10, -1/10

(10)(-½) = (-5)
Hope it helps you.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
