How many integers between 27 and 53 have a remainder of 4 divided by 6
marusya05 [52]

Answer:

There are 4 integers between 27 and 53 that have a remainder of 4 divided by 6.

Step-by-step explanation:

At first we need to find which integers between 27 and 53 are divisible by 6, which are, respectively:

A =\{30, 36, 42, 48\}

All integers that have a remainder of 4 divided by 6 are found by summing 4 to each element of A, that is:

A' = \{34,40,46, 52\}

There are 4 integers between 27 and 53 that have a remainder of 4 divided by 6.

What would the one-month interest be for a $5,000 credit card balance with a 12% APR?
Ilia_Sergeevich [38]

Answer:

$50

Step-by-step explanation:

Personally I use a debit and I don't "own" my own card so I'm not good with this stuff quite yet. I looked up a calculator though and $50 seems to be it. (minimum time was 3 months so I divided it by 3 to get $50.)
