Which number is greater,
23×10^3
or
11×10^4?

How do you know? Explain your steps.

Answers

the greater number would be 11•10^4

to know this, you have to evaluate each equation and compare your answers.

10^3 = 1,000
23•1,000 = 23,000

10^4 = 10,000
11•10,000 = 110,000

110,000 > 23,000

(hope this helps some)

[tex]11\times 10^4[/tex] is the greater number among the given.

The given numbers are 23×10³ and [tex]11\times 10^4[/tex].

We need to identify which is the greater number among the given.

What is scientific notation?

The scientific notation helps us to represent the numbers that are very huge or very tiny in a form of multiplication of single-digit numbers and 10 raised to the power of the respective exponent. The exponent is positive if the number is very large and it is negative if the number is very small.

Now, 23×10³=23×1000=23000 and [tex]11\times 10^4[/tex]=11×10000=110000

Therefore,  [tex]11\times 10^4[/tex] is the greater number among the given.

Using the drawing tool, graph the two inequalities on the number line. Take a screenshot of each number line and submit it in the response area below. For this scenario, how does the origin, zero, affect the graphing of the inequalities? What does zero represent? Type your answers in the response area.

Answers

The attached number lines represent the inequalities x ≥ 22 and x > -22

The inequalities

To answer these questions, we make use of the following inequalities

x ≥ 22 and x > -22

The ≥ inequality sign uses a closed circle, while the > inequality sign uses an open circle.

See attachment for the number line

The impact of the origin

The origin of a number line is the point zero on the number line.

It affects the graphing of the inequality because it differentiates between the positive sign and the negative sign.

Also, it is always the midpoint of the number line

What zero represent?

The point zero represents the origin of the inequality number line

The length of a rectangle is twice its width. If the perimeter of the rectangle is 48 ft , find its length and width of the rectangle.

Answers

Answer:

length=16ft

width= 8 ft

Step-by-step explanation:

Perimeter of rectangle = P = 48ft

Length = 2w

Width = w

Perimeter of rectangle = 2(Length+Width)

48=2(2w+w)

48=2(3w)

48=6w

48/6=6w/6

8=w

w=8ft

 

Length = 2w = 2(8)=16ft

Width = w = 8ft

Answer:

The length is 16 ft and the width is 8ft

Step-by-step explanation:

48 divided by 4 = 12

one has to be double of the other

12-4=8

12-4=8

12+4=16

12+4=16

16+16+8+8=48

Answer:

What is the image of the point (6, -4) when rotated 180 degrees anticlockwise about the origin?

(-6, -4)

(-6, 4)

(4, 6)

(-4, -6)

the answer is (-6, 4).

If the coordinate is rotated 180 degrees anticlockwise about the origin, the resulting coordinate will be (-6, -(-4)) = (-6, 4)

Given the coordinate point (x, y). If this coordinate is rotated 180 degrees anticlockwise about the origin, the resulting coordinate will be at (-x, -y)

We can see that the given coordinates were negated to get the resulting coordinate.

For the image of the point (6, -4), if the coordinate is rotated 180 degrees anticlockwise about the origin, the resulting coordinate will be (-6, -(-4)) = (-6, 4)
