Two identical square tables are combined to create a rectangular table, as shown. A third identical square table will be added to create a longer rectangular table. Which expression reveals the number of chairs along each side of the longer rectangular table

Answers

Answer:

456 chairs

Step-by-step explanation:

If there are 6 round tables with 7 chairs each you would multiply 7, 6 times (7 x 6) = 42

If there are 23 rectangular tables with 18 chairs each you would multiply 18, 23 times. ( 18 x 23) = 414

Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.
Answer the following questions about kileys trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that kiley is at rest.
In this task you will write the ratio of miles to hours for each leg of kileys trip. You will then express the ratio as a decimal number. Next you will find the unit rate in miles per hour for each leg of the trip.

1. The car ride from kileys house to the airport

Answers

The answer is just 24.3 miles.

The questions asked "How long was the ride from Kiley's house to the airport?"

The first sentence of the problem reads "They drove 24.3 miles from their house to the airport in an hour". The rest of the information isn't necessary to find this answer.

Help Its math Im stuck!

Answers

C is correct.


Reasoning: If the top number (numerator) is smaller that the bottom number (denominator), it means it’s smaller than 1. If, on the other hand, the numerator is bigger than the denominator, it means it’s more than 1. If youre ever unsure, devide the numerator by the denominator. This will turn the number into a decimal, and be easier to see. 8/9 = 0.88 repeated, and 3/7 = 0.4285. Therefore 8/9 is larger than 3/7. This can also be written as 8/9 > 3/7.

Good luck!
C is correct because both number are smaller than 8/9

In 1999, there were 9860 Great Danes registered with the American Kennel Club. The number of registered Labrador Retrievers was 6997 more than fifteen times the number of registered Great Danes. How many registered Labrador Retrievers were there?
show your work please

Answers

Answer:

154,897 REGISTERED LABRADOR RETRIEVERS WERE THERE

Step-by-step explanation:

Given the statement: IN 1999, THERE WERE 9860 GREAT DANES REGISTERED WITH THE AMERICAN KENNEL CLUB.

Also, THE NUMBER OF REGISTERED LABRADOR RETRIEVERS WAS 6997 MORE THAN FIFTEEN TIMES THE NUMBER OF REGISTERED GREAT DANES

Let x represents the number of Great Danes registered and y represents the number of Labrador retrievers registered.

The statement:

"Fifteen times the number of registered great Danes " means 15x

and

"6997 more than fifteen times the number of registered great Danes" means 15x + 6997

then as per the given statement:

x = 9860 .

To solve for y;

y = 15x+ 6997

Substitute the value of x we get;

Simplify:

y = 154,897

Therefore, the registered Labrador Retrievers were there are; 154,897
