Carlos biked StartFraction 139 / 8 EndFraction miles on Saturday and StartFraction 135 / 7 EndFraction miles on Sunday. On which day did he ride further and by how much? Carlos rode further on Saturday by 1 and StartFraction 51 / 56 EndFraction miles.
Carlos rode further on Saturday by 3 and StartFraction 5 / 56 EndFraction miles.
Carlos rode further on Sunday by 3 and StartFraction 51 / 56 EndFraction miles.
Carlos rode further on Sunday by 1 and StartFraction 51 / 56 EndFraction miles.

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
