Answer: \bold{(D)\ a_n=7n+10}

<u>Step-by-step explanation:</u>

The recursive rule for an arithmetic sequence is: a_n=a_{n-1}+d

So, we know that d = 7.  It is given that a_1=17

The explicit rule for an arithmetic sequence is: a_n=a_1+d(n-1)

a_n=17+7(n-1)\\\\.\quad=17+7n-7\\\\.\quad=7n+10

Work out each map scale as a map ratio
vampirchik [111]
1:500000
1cm:500000cm

2:250000
2cm:250000cm
1cm:125000cm

To get this you convert the km into cm as it is easier and then it becomes something like this 2cm : 250000cm
then divide or half to get to the simpler form like this 2cm divided by 2=1cm and 250000cm divided by 2= 125000cm 
then put into ratio is 1:125000

spin [16.1K]

Answer:

I think it's 1/6 for the cube and 1/2 for the coin. so it would be 2/8 which would be 1/4 simplified, so in decimal form the probability is .25
