The perimeter of a shape will always be greater then the area of the shape

Not necessarily. For example, you can have a rectangle whose dimensions are 12 and 6. Length is 12 and 6 is the width.

The area (length × width) of the rectangle will be 72.

The perimeter of the rectangle (2l + 2w) will be 36.

So, in this case, the area was double the perimeter and the perimeter was not greater than the area of the shape.

Alice and Bob each have a certain amount of money. If Alice receives n dollars from Bob, then she will have 4 times as much mone

posledela

Answer:

$A:B=-8n:-27n\\\\=8:27$

Step-by-step explanation:

Let the A be the amount Alice initially has and B be Bob's initial amount.

#Alice receives $n from Bob:

$4(A+n)=B-n\ \ \ \ \ \ \ \ \ i$

#Alice gives n to Bob:

$3(A-n)=B+n\ \ \ \ \ \ \ \ \ \ ii$

#We simultaneously solve the two expressions:

$4(A+n)=B-n\\\\3(A-n)=B+n\\\\=>from \ i\\4A+4n+n=B\\\\4A+5n=B\\\\\# substitute \ in \ ii\\\\3A-3n=4A+5n+n\\\\A=-8n\\\\B=4A+5n=4(-8n)+5n=-27n$

The initial amounts of Alice is -8n and Bob's is -27n

#We find the ratio of Alice:Bob:-

$A:B=-8n:-27n\\\\=8:27$

Hence the ration of Alice to Bob is 8:27

From her house, Haley could drive due north to get to her parents' house or she could drive due east to get to her grandparents'

vivado [14]

Answer:

5.7km

Step-by-step explanation:

-let the drive east be the base of our 'triangle' and the drive north be the height, h.

-The distance from the parents to the grandparents, 9km, forms the hypotenuse.

#Using Pythagorean Theorem, we can find the distance to her grandparents as:

$H^2=h^2+b^2\\\\9^2=7^2+b^2\\\\b^2=81-49\\\\b=\sqrt{32}\\\\=5.657\approx5.7\ km$

Hence, the distance fro Hayley's place to her grandparents is 5.7km
