How do I find the the perimeter of a rectangle
in a coordinate plane

Answers

Answer 1
Answer:
From the way you worded the question, it sounds like you have
the (x, y) coordinates of each corner of the rectangle.

The perimeter of any shape is the distance all the way around it,
or the sum of the lengths of all the sides.

So you have to take the coordinates of the four corners of the
rectangle, and find the length of each side ... that's the distance
between each pair of corner-points.  Then addum up to get the
perimeter.

I know finding the distance between two points is a pain, so I'll
tell you a way to make it a bit simpler:  You don't actually need to
do it 4 times.  You can get away with doing it only 2 times, and
you'll have enough information to find the perimeter.

Take the coordinates at the ends of any side of the rectangle.
Find the distance between them.  The side opposite that one
has the same length.

Then take the coordinates of either side that hooks onto the
side you just did.  One end of it will have the same coordinates
that you just worked with.  Find the distance between the two ends.
You know that this distance is the other dimension of the rectangle,
and you also know that the side opposite it has the same length.

So now, you found the distance between two pairs of points,
and you know both dimensions of the rectangle, and you know
the length of all four sides.

Now you can wrap it up !

A trapezoid’s longer base is three times the length of its shorter base. If the trapezoid has an area of 32 square feet and a height of 4 feet, what is the length of each base?

Answers

Answer:

longer base: 10 2/3

shorter base: 5 1/3

Step-by-step explanation:

you first take 32 divided by 4 and then multiply that by 2 and you get 16 and then you divide that by 3 and you get 5 1/3 but then the longer one is 5 1/3 plus 5 1/3 (i hope that makes sense)

What is the correct way to write 1/4% as a decimal

Answers

Answer:

1/0.04 = 25

Step-by-step explanation:

Answer:

Step-by-step explanation:

well 1/4% wouldnt be 25% because they are 25% = 0.25 = 1/4

the percentage sign changes everything

since it is 1/4% rather than 1/4 by itself

1/4% = 0.25%

if you want to know the percent as a decimal you move the "." to the left twice

(or divide by 100)

so that means that the decimal of 0.25% would be 0.0025

77,098 rounded to the nearest thousand

Answers

The number 77,098 rounded to the nearest thousand is 77,000.

The given number is 77,098.

We need to round the given number to the nearest thousand.

How do round the number to the nearest thousand?

There are some basic rules and steps that need to be followed for rounding numbers to the nearest thousand.

  • Mark the number that we need to round. In this case, we will mark the digit in the thousands place. This rounding digit will be the one that will eventually be affected.
  • Since we are rounding to the nearest thousand, we need to check the digit to the immediate right of the thousands place, that is the hundreds place.
  • If the digit in the hundreds place is less than 5, we do not change the digit in the thousands place. However, all the digits to the right of the thousands place are changed to 0.
  • If the digit in the hundreds place is 5 or more than 5, we increase the thousands place by 1, and all the digits to the right of the thousands place are changed to 0.

Now, in 77,098 the digit in the hundreds place is 0 which is less than 5, so the number is rounded down, is 77,000.

Therefore, the number 77,098 rounded to the nearest thousand is 77,000.

77,098 is closer to 77,000 than it is to 78,000, so rounded to the nearest thousand it would be 77,000.

How do you make a 10 to find 13-8

Answers

You can "make 10" out of either the positive number or the negative one.

13 - 8

= (10 +3) -8 = 10 +(3 -8) = 10 -5 = 5

= 13 -(10 -2) = (13 -10) +2 = 3 +2 = 5

The sum of the angle measures of a quadrilateral is 360°. Find the value of x. and then Find the angle measures of the quadrilateral in order from least to greatest. plsss

Answers

Answer:

x = 120°: 60°, 60°, 120°, 120°

Step-by-step explanation:

x + x + 0.5x +0.5x = 360°

3x = 260°

x = 120°

0.5x = 60°

Final answer:

To find the measure of an angle in a quadrilateral when the other angles are known, subtract the sum of the known angles from 360 degrees. However, the original question does not provide sufficient data to determine specific angle measures or the value of 'x'.

Explanation:

Without additional information, it is impossible to determine the specific measure of each angle of the quadrilateral or the value of 'x'. When working with quadrilaterals, it's known that the sum of the interior angles is always 360 degrees. If given the values of three of the angles, you can calculate the fourth by subtracting the sum of the three given angles from 360.

For example, if you know that the value of three of the quadrilateral's angles are 90°, 90°, and 70°, you can find the fourth angle by performing the following calculation: 360° - (90° + 90° + 70°) = 110°. Therefore, the angle measures in order from least to greatest would be 70°, 90°, 90°, and 110°.

However, without the necessary information provided, such as the values or expressions representing the angles, a detailed explanation and accurate answer cannot be provided.
