5. Debbie should've rounded the 2008 to 4,600 because 4,637 is less than 4,650. If it was over 4,650 it would've been rounded to 4,700. With the knowledge of the over 4,650 rule, we automatically know that in 2012 she was correct when she said 4,700.

Debbie is correct because you can not a percentage of a person therefore you have to round it, and if there was 5,000 female athletes in 2008 and 4,700. If you take 5,000 and subtract 4,700; the answer is 300.

An Airbus A380 has 1 first class section 1 business class section and 4 economy class sections
Juliette [100K]

Answer:

Yes, more than half are being used.  (292 out of 546 used)

Step-by-step explanation:

The first part of this problem is to determine the total amount of seats on the plane so we can determine what half of the seats would be.

1st class has 14 seats.

Business-class has 64 seats.

And the 4 economy classes have 117 each, meaning 117 * 4 = 468

So the total amount of seats are 14 + 64 + 468 = 546

So half that amount would be 273.

Now we can determine the number of seats being used.

1st class has (6/7) * 14 = 12 seats used

Buisness-class has (7/16) * 64 = 28 seats being used

Economy has 4 * (7/13) * 117 = 4 * 63 = 252 seats being used

So the total amount of used seats would be 12 + 28 + 252 = 292.

Note that 292 is greater than 273, so there is indeed more than half the seats on the plane being used.

Cheers.

*6. Five brothers each bought two hot dogs & a bag of chips. If the chips
Oxana [17]
D- 1.65 per hot dog

Take the amount of the bag of chips which is 1.25 and multiply it by 5 because that’s how many people there are and they each bought one bag
1.25 x 5= 6.25
Next you want to subtract that amount from the total so we can just have the amount of money spent on hot dogs
22.27-6.25=16.50
Then you want to divide 16.50 by 5 because they all bought the same amount of hot dogs and this will get us to the amount of to hot dogs
16.50/5=3.30
Finally you want to divide 3.30 by 2 which will get us the price for 1 hot dog
3.30/2=1.65

There you go!!
