If Delta and United just arrived at the airport when will the next to arrive at the airport at the same time

Answers

Answer 1

Answer: Alright so if Delta comes every 4 minutes and United arrives every 6 minutes, the time would be 12 minutes when they would arrive at that the same time because, 4 times 3 = 12 and 6 times 2 = 12 so you must find out the least common multiple to do so. I hoped that helped in an sense.

Ricardo has a $50 gift card for an electronic store. he also has a coupon good for $10 off his purchase. Let a represent the amount of merchandise Ricardo can buy from the store using his gift card and coupon. Write and solve any quality to represent the situation

Answers

Well, that means he can buy 60$ in the shop.
Because: if he buys something of 60$ (we'll forget the taxes since it is not mentioned), and has 10$ off, that means the item drops to 50$. And then he can use his full gift card.

Answer:

a < 60

Step-by-step explanation:

First off, he has a gift card ($50), plus the coupon ($10), so he can spend a total of $60.

Now we know he can only buy $60 worth of stuff. We cannot go over this amount.

So the inequality is a < 60. But also we can get exactly $60 dollars of things or less so actually, the inequality is a < 60

Howto multiply 30 times 30 HELP

Answers

30=3 times 10 right so
30 times 30=3 times 10 times 3 times 10=3 times 3 times 10 times 10
we know that 3 timmes 3=9
and 10 times 10 is 100
so 30 times 30=9 times 100=900

Here is a way I was thought with zeroes, first do 3x3 which is 9 then since there are 2 zeroes you tack on 2 zeroes at the end to get 900. Hope this helped.

what is the rhee and pamela are two of the five members of band. every week the band picks 2 members at random to play on their own for five minutes. what is the probability that rhee and pamela are chosen this week.

Answers

First you need to count the number of different two people groups you can make.

That is 5x4/2 = 10 different groups (this is because you can choose the first member from 5 different persons and the second member from 4 different persons, which makes 5 x 4; then you realize that in that way every couple is counted twice and so you have to divide by 2).

If you do not see that, you can count in this way. Identify every person with one letter: a, b, c, R and P

you can do these different two people groups:

ab
ac
aR
aP

bc
bR
bP

cR
cP

RP

Thos are the ten different groups.

Rhee and Pamela is one group, so the probability of chosing it is
