Round 23,421 to the nearest thousand and ten thousand on a number line

Answers

Answer 1
Answer:

nearest thousand: Look at the place value to the right of thousands, the hundreds place value. It is a 4. Because 4 is less than 5, round down.

nearest thousand: 23000

Nearest ten thousand: Look at the place value to the right of the ten thousands, which is the thousands place value. It is a 3. Because 3 is less than 5, round down

nearest ten-thousand: 20000

hope this helps

Three vertices of a rectangle are (–3, 4), (5, 4), and (5, –2). 

What are the coordinates of the fourth vertex of the rectangle? 

         A. (–3, –4)                                               

        B. (–3, –2)                                               

     C. (5, –3)      

       D. (5, 2)

Answers

A =(-3, 4), \ \ B= (5, 4),\ \ C= (5, -2)\n \n The \ slope \ of \ AB : \n \n \n m= (y_(2)-y_(1))/(x_(2)-x_(1) ) = (4-4)/(5+3)=(0)/(8)=0\n \n The \ slope \ of \ CB :\n \n m= (y_(2)-y_(1))/(x_(2)-x_(1) ) = (5-5)/(-2-4)=0

The \ slope \ of \ lines \ parallel \ is \ the \ same \n \nTo \ find \ the \ coordinates \ of \ the \ fourth \ vertex, \ add \ the \ coordinates \n of \ A \ and \ C \ together, \ and \ subtract \ the \ coordinates \ of \ B. \n \n The \ fourth \ vertex \ is: (-3+5-5; 4-2-4) = (-3, -2) \n \n Answer: \ B. \ \ (-3, -2)

 
 

The rectangle doesn't necessarily have to be standing up straight or laying down flat
on the graph.  It could be tilted ... leaning.  Dealing with those coordinates would be
a nightmare, and since you're in Middle School and just learning this stuff, we can be
pretty sure that the rectangle in this problem is straight on the graph.

If we think about it for a second, and visualize a rectangle in our mind, we realize that:

-- Both top corners have the same y-coordinate.
-- Both bottom corners have the same y-coordinate.
-- Both corners on the left side have the same x-coordinate.
-- Both corners on the right side have the same x-coordinate.

The first two points given in the question are ( -3, 4) and (5, 4).

-- They have the same y-coordinate, so they must be either the top
or the bottom two corners.

-- We also know right away that the left side of the rectangle is at x = -3
and the right side of the rectangle is at x = 5 .

Now look at the third given point ... (5, -2) . 

-- Its x-coordinate is 5 so we know it's a corner on the right side.

-- But we already had one corner on the right side ... the point at (5, 4).
This new one is lower.

-- So now we know that (5, 4) was the upper right corner, (-3, 4) was the
upper left corner, and this new point is the lower right corner.

All we're missing is the lower left corner.

We know now that the left side is at x = -3 and the right side is at 5 .
We also know now that the top is at y = 4 and the bottom is at y = -2 .

So the bottom left corner is (-3, -2).  That's choice - 'B' .

A baseball weighs 5 ounces. How much do 6 baseballs weigh?

Answers

This is a question that involves multiplication. If 1 baseball weighs 5 ounces, and you're trying to find out how many 6 weigh, multiply 5x6. The answer is 30. Hope this helps.

Answer: 1 pound and 14 ounces


Step-by-step explanation:

...

2x+4≥24
solve for x
plz help me!

Answers

In order to solve for x, we must isolate it on one side of the inequality.

2x + 4 ≥ 24

The first step we will take is subtract 4 from both sides, since it is being added on the side with the variable.

2x + 4 ≥ 24
     - 4    - 4

And the inequality now is 

2x ≥ 20

Now, all we have to do is divide both sides by 2, since the variable is being multiplied by 2.

2x ≥ 20
 /2     /2

And the final inequality is

≥ 10

Hye Sun has a modern coffee table whose top is a triangle with the following side lengths: 8 feet, 3 feet, and 5 feet. Is Hye Sun's coffee table top a right triangle?

Answers

you can check this by using the Pythagorean theorem

8²-5² = 39

3² does not = 39 therefore this is not a right triangle
