A rectangular garden is 6 feet long and 4 feet wide. A second rectangular garden has dimensions that are double the dimensions of the first garden. What is the percent of change in perimeter from the first garden to the second garden?

Answers

Answer 1
Answer:

First rectangular garden:

length = 6 feet and width =4 feet

Perimeter of first garden =2(l+w) =2(6+4) =20 feet...........(1)

Second rectangular garden:

second rectangular garden has dimensions that are double the dimensions of the first garden

length =2* 6 =12 feet and width =2* 4 =8 feet

Perimeter of second garden =2(12+8) =2*20=40 feet

percentage change in perimeter = (perimeter of second garden-perimeter of first garden)/(perimeter of first garden ) *100

% change = (40-20)/20 *100 =100

% change =100%

How much is 20% of $350.00? How do I find this answer?

Answers

20% of 350.00 is 70, you find this by multiplying 20% by 350 to get your final answer.
A percent is a decimal multiplied by 100. 0.5, for example, is 50% because 0.5 x 100 is 50. So 20% is 0.2. Multiply 350 by 0.2 to get 20 percent of 350

350 x 0.2= 70
$70 is 20% of 350

Is -0.3 a rational number? is 3.14144144414444... a rational number?

Answers

I will try to make this as simple as possible.

First off, we need to know what a rational number is: A rational number is any number that can be made by dividing 2 integers. For example:

1.5 would be a rational number because 1.5 = 3/2 (3 and 2 are both integers)

With that being said, let's begin.

First off, let's start with -0.3, let's ask ourselves, can we make this number by dividing 2 integers, the answer is yes, we can, by doing (-3)/(10) we have the equivalent of -0.3, so now we know it's a rational number.

As for the second one, it can't be a rational number because it can't be made by dividing to integers, so the answer is:

-0.3 is a rational number, but 3.14144144414444 is not.
