Answer:
B: 5/13
Step-by-step explanation:
pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5
sin = opp/hyp
sin 5/13

The subway car passes through 48 stations in 2hours
It is given that a subway car passes 4 stations every 10 mins.
Subway car is being referred to the metro system of New York city
It is known to us that an hour has 60 mins
We are given that subway car passes 4 stations every 10 mins
Therefore number of stations passed by subway car in 1 hour
= 60/10 x 4 = 24 stations
We are required to find the number of stations crossed by subway car in 2 hours
Therefore, number of stations crossed by subway car in 2 hours= 24 x 2
= 48 stations
Therefore, the subway car passes 48 stations in 2 hours

GCF stands for Greatest Common Factor
12 can be divided by 1, 2, 6, 3, 4,
40 can be divided by 1, 2, 4, 10, 20, 5, 8
45 can be divided by 1, 3, 15, 9, 5
So out of all those factors the greatest factor is 2
Answer: v= -10 & 1
Step-by-step explanation: first take out the gcf, in this case, 3.
3(v^2 +9v-10)
then factor that
3(v-1) (v+10)
solve.
v=1 and v= -10
