First of all, you must change 40% into a decimal by multiplying by 100⇒.40
Then you divide 55 by .40
55÷.40=137.5
Therefore, 55 is 40% of 137.5

Take 55 and divide it into 40% by changing 40% into decimal form, (because a percentage is not a whole number), like this: .4. Then, 55/.4, which is 137.5.

AVprozaik [17]

Answer:

$Length= 429 feet\\Width=143feet$

Step-by-step explanation:

Perimeter of the rectangle= 1144 feet

Length=3*Width

L=3*W

Perimeter of rectangle:

$2(Length+Width)\\\\ 1144=2(3W+W)\\\\ 1144/2=3W+W\\\\ 572=4W\\\\ W=572/4\\\\ W= 143 feet\\\\Width=143 feet\\\\Length=3*143=429 feet\\\\$

The Dimension of the rectangle is :

$Length= 429 feet\\Width=143feet$

Nataly [62]

Step-by-step explanation:

Given : A triangle with side lengths $a = x^2-1, b = 2x, \text{ and } c = x^2 + 1$

To find : Prove that when x > 1, it is a right triangle. Use the Pythagorean theorem and the given side lengths to create an equation. Use the equation to show that this triangle follows the rule describing right triangles. Explain your steps ?

Solution :

For right triangle the Pythagorean theorem is to be satisfied.

i.e. $c^2=a^2+b^2$
