CECE HIKING ON A MOUNTAIN AND STOPS AT 15 5/8 FEET ABOVE SEA LEVEL .THE BASE OF THE MOUNTAIN IS 10.2 FEET BELOW SEA LEVEL .WHAT IS THE VERTICAL DISTANCE BETWEEN CECE AND THE BASE OF THE MOUNTAIN?

Answer:The vertical distance is 25.825 ftStep-by-step explanation:we know thatTo find out the vertical distance between Cece and the base of the mountain, subtract the height of the base of the mountain from the height of CeceLetx -----> the height of Cecey ----> the height of the base of the mountainwe have[tex]x=15\frac{5}{8}\ ft[/tex] ----> is positive because is above sea levelconvert to an improper fraction[tex]x=15\frac{5}{8}\ ft=\frac{15*8+5}{8}=\frac{125}{8}=15.625\ ft[/tex][tex]y=-10.2\ ft[/tex] -----> is negative because is below sea levelso[tex]x-y=15.625-(-10.2)=15.625+10.2=25.825\ ft[/tex]Remember that -1*(-1)=+1
