Greg plans to purchase a bicycle. bike a costs $270 and has an expected maintenance cost of $36 per year. bike b costs $360 and has an expected maintenance cost of $20 per year. which statement is true based on the average annual cost of each bike?
bike a is the better choice if greg plans on owning the bike for 5 years or 6 years.
bike b is the better choice if greg plans on owning the bike for 5 years or 6 years.
bike a is the better choice if greg plans on owning the bike for 5 years. bike b is the better choice if greg plans on owning the bike for 6 years.
bike b is the better choice if greg plans on owning the bike for 5 years. bike a is the better choice if greg plans on owning the bike for 6 years.

The Option 'Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years' is true.

Step-by-step explanation:

If x represents number of year and y represents the total cost  of the bike.

According to the question for bike A, total cost, y= 270+36x

And, for bike B, total cost, y= 360+20x

For 5 years price of A = 270 + 36 × 5=270 +180 = 450 dollar

For 5 years price of B= 360+ 20 × 5=360+100= 460 dollar

Thus, for 5 years price of A< price of B

⇒For 5 years Bike A is the better choice than Bike B.

For 6 years price of A = 270 + 36 × 6=270 +216 = 486 dollar

For 6 years price of B= 360+ 20 × 6=360+120= 480 dollar

Thus, for 6 years price of A> price of B

⇒For 6 years Bike B is the better choice than Bike A.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
