Convert these base five and base two numbers to base ten.
a. 1312ve
b.110110110two

I am assuming A is base 5 based on the ve

a. 1*5^3 + 3*5^2 + 1*5^1+ 2*5^0
125+75+5+2

a = 207

b. 2+4+16+32+128+256

b = 438

(please note that a binary number having 9 digits is highly unusual. most are normally 8 which makes up a bit)

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 )
