Answer:
As we know rectangles have 90 degree angles at all 4 of its corners.
In this question we know that the length is 4 feet while the bredth is 3 feet.
Therefore to solve this answer we can use the Pythagoras theorm.
By Pythagoras:

Therefore the diagonal must be 5 feet
So if Luisa measures the diagonal with a tape and it measures 5
Then it proves that all 4 corners due have 90 degree angles
Please do mark my answer as brainliest. It would really help me answer more of such questions in the future :)
Answer:
$857 billion
Step-by-step explanation:
Since 2006, the amount of money spent at restaurants in a certain country has increased at a rate of 5% each year. In 2006, about $580 billion was spent at restaurants.
2014-2006=8 so 2014 is 8 years from 2006
If the trend continues, the amount of money spent at restaurant in 2014 will be (1.05)^8 times that of the amount in 2006:
$580*(1.05)^8 = $856.9
About <u>$857</u> billion will be spent at restaurants in 2014 if the trend continues.
