state whether ordered pair of numbers is a solution of the sentence:3y>2x+1;(4,3)

Answers

3y > 2x + 1

You have asked us to check out the point where x=4 and y=3 .
All we need to do is to plug those numbers in place of 'x' and 'y',
and see whether the resulting statement is true:

3y > 2x + 1

3(3) > 2(4) + 1

On the left side, 3(3) is the same as 9.
On the right side, 2(4) + 1 is the same as (8 + 1) and that's 9 .

So the statement says: 9 > 9 , and that's not true.
9 is equal to 9, it is not greater than 9 .

So this point is not a solution of the inequality.

$3\cdot3>2\cdot4+1\n 9>9$

It's not.

What expression can be used for estimating 868 divided by 28

Answers

868 is about 870, and 28 is about 30, so your expression would be 870 divided by 30 which would be 29 and the actual answer is 31, so your estimate would be close to your actual answer.

You could do 870/30=29.
Or you could do 868/28=31 and then round it but it looks like it doesn't need rounding.

What is the Volume of a Rectangle?

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the total volume of the rectangular set of stairs be represented as V

Now , the value of V is

Let the volume of the first stair be A

The length of stair A = 30 inches

The width of A = 12 inches

The height of A = 4 inches

Volume of Rectangle = Length x Width x Height

So , the volume of stair A = 30 x 12 x 4 = 1,440 inches³

Let the volume of the second stair be B

The length of stair B = 30 inches

The width of B = 36 inches

The height of B = 4 inches

Volume of Rectangle = Length x Width x Height

So , the volume of stair B = 30 x 36 x 4 = 4,320 inches³

Let the volume of the third stair be C

The length of stair B = 30 inches

The width of B = 60 inches

The height of B = 4 inches

Volume of Rectangle = Length x Width x Height

So , the volume of stair C = 30 x 60 x 4 = 7,200 inches³

Now , the total volume of stairs V = A + B + C

On simplifying , we get

The total volume of rectangular stairs V = 1,440 + 4,320 + 7,200 inches³

The total volume of rectangular stairs V = 12,960 inches³

Hence , the volume of rectangular stairs is 12,960 inches³

The volume formula is area of base×height. In this case, we are working with rectangles, so the formula is l×w×h. We have to find the volume of each block and add them together. Top rectangle: 12×30×4=1440. Middle rectangle: 30×36×4=4320. Bottom rectangle: 30×60×4=7200. 7200+4320+1440=12960 inches squared.
