grant starteda marathon at 8:00 A.M. he took 4 hours 49 minutes to complete the marathon. when did he crosd the finish line

Answers

If he starts at 8:00 AM and you start counting up by 1 hour at a time...

8:00 - 9:00 = 1 hour
9:00 - 10:00 = 1 hour
10:00 - 11:00 = 1 hour
11:00 - 12:00 = 1 hour

So far that is 4 hours that have passed and we are up to 12:00.  Now remember, when we reach 12:00 we switch from AM to PM (that's 12 noon). 

We only have 49 minutes left so now we just add that in

12:49 PM is when he crossed the finish line.

Mr.king picked up tomatoes from his garden and got 21 cups of chopped tomatoes. he used 5 1/2 cups of the tomatoes to make spagatti. he also used 2 1/4 cups of the tomatoes to make chilii. he seprated the remaining chopped tomatoes into 2 equals portions and froze them. how many cups of tomatoes were in each portion that he froze?ANSEWERS AVALIABLE
A, 3 7/8 C, 13 1/4
B, 5 5/8 D, 6 5/8

Answers

Start with 21 cups , substract 5.5 (5 and one half) , 2.25( 2 and one fourth), and then divide by two (divided into 2 equal portions) and the result is 6.625 and if you divide the options as an improper fraction, you'll get 6 and five eights... so your answer is D.

Which of the following gives all of the sets that contain squrt 9the set of all irrational numbers
the set of all natural numbers, the set of all whole numbers, and the set of all integers
the set of all integers, the set of all rational numbers, and the set of all real numbers
the set of all natural numbers, the set of all whole numbers, the set of all integers, the set of all rational numbers, and the set of all real numbers

Answers

Answer:

Option C (the set of all integers, the set of all rational numbers, and the set of all real numbers).

Step-by-step explanation:

The value of square root of 9 is ±3. This means that there two answers to square root of 9: 3 and -3.

As far as 3 is concerned, it is one of the elements of the natural number set. It is already known that natural numbers are also whole numbers, also integers, also rational numbers, and also real numbers.

As far as -3 is concerned, it is not a natural number since the set of natural numbers does not contain negative numbers. -3 is an integer. Which means that -3 is also a rational number and also a real number.

After identifying the common sets and taking the intersection of both the above classifications, it yields the set of all integers, the set of all rational numbers, and the set of all real numbers, Therefore, Option C is the correct answer!!!

Answer:

the set of all integers, the set of all rational numbers, and the set of all real numbers

contestants in a dance marathon rest for the same amount of time every hour. a couple rests for 27 minutes in 6 hours. how long does the couple rest in 8 hours? Show your work.

Answers

In the given question, there are several important information's that needs to be noticed. based on these information's the correct answer to the question can be easily deduced. It is already known that the contestants rest for the same amount of time every hour. In 6 hours they rest for 27 minutes. The 6 hours has to be converted to minutes first.
Then 6 hours = (6 * 60) minutes
                       = 360 minutes
So we have to first determine the amount of rest each contestants take in 1 hour.
Then
In 360 minutes the couple rests for a total time = 27 minutes
In 60 minutes the couple will rest for = (27/360) * 60
                                                           = 4.5 minutes
So the couple rests for 4.5 minutes in 1 hour
Then
In 8 hours the couple will rest for = (8 * 4.5) minutes
                                                     = 36 minutes.
The couple will rest for 36 minutes in 8 hours.
