Kara and Nathan are each painting a poster for the school dance. Their posters have the dimensions shown in the table.

Student Poster Length (ft) Poster Width (ft)
Nathan L112 W112
Kara L334 W334

How many times greater is the area of Kara’s poster than Nathan’s? Write in simplest fraction form.

Answers

It’s 8.89317 times greater. Normally u find an area of a rect thru lw so j do that but make it a proportion. (334x334)/(112x112)=8.9317

Kara's poster is 8.89 times greater than Nathan's poster.

What is the area of the square?

The square is defined as a quadrilateral having all the sides equal to each other. The angle suspended by all the sides of the square is 360 degrees.

Given that the dimensions of Nathan's painting are L112 W112 and the dimensions of Kara's painting are L334 W334.

The areas will be calculated as below:-

Nathan = 112 x 112 = 12544

Kara = 334 x 334 = 111,556

To calculate how many times greater the area of Kara’s poster than Nathan’s divide Kara's area by Nathan's area.

Kara / Nathan = 111556 / 12544 = 8.89

Kara = 8.89 x Nathan

Therefore, Kara's poster is 8.89 times greater than Nathan's poster.

D. 3 3/4

Answers

Answer:

Step-by-step explanation:

D. 3 3/4 is your answer.

Answer:

D. :)

Step-by-step explanation:

So you can do the keep, change, flip method to help.

So first, you keep the 4 11/16 or 75/16. Then, you change the division to mutilpation and then lastly you flip the 1 1/14 or 5/4 to 4/5.

So then the problem is 75/16 x 4/5. So, first you do 75 x 4 to get 300, then you do 16 times 5 to get 80. So now the problem would be 300/80.

So, now you divide 300 by 80 to get 3.75. And if you know, 3.75 is equal to 3 3/4.

Hope this helps love!! :)

Answers

Answer:

Yes

Step-by-step explanation:

If the building is 52 feet tall then the cable can stretch from the top of the building to the bottom, so therefore if it is hung 12 feet from the base of the building it would only need to stretch 12 feet from bottom to top which it can do. Hope this helps :)
