Please answer with steps
{0.4), (-4,-6)

Multiple: 0 * 4 = 0
Conversion a decimal number to a fraction: -4 = -4/1 = -4./1

a) Write down the decimal -4 divided by 1: -4 = -4/1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
-4/1 =
Note: is called a decimal fraction.

c) Simplify and reduce the fraction
= 0 * 1/0 * 1 = 0 * 1/0 * 1= 0/0
Subtract: -4 - 6 = -10

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 )
