I think C

Step-by-step explanation:

Step-by-step explanation:

yeah option C is correct .

as for option one the expression will be,

145/11.60

for, option B the equation will be,

let just say he pays 11.60$ in monthly dues.

11.60$ × 12 ( as 1 yr contains 12 months ) + 145 ( to join the gym)

= ( 11.60 × 12 ) + 145

and for option D,

if cost of each coupon is 11.60$

so cost of 145 coupon = 11.60$ × 145

so option C is correct!

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

10.416 meters per second
