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.

A local hamburger shop sold a combined total of 613 hamburgers and cheeseburgers on Wednesday. There were 63 more cheeseburgers sold than hamburgers. How many hamburgers were sold Wednesday

Answers

Answer:

This problem can be solved through the creation of a system of equations relating the number of hamburgers (x) and cheeseburgers (y).

Having a combined total of 603 hamburgers and cheeseburgers can be written as x+y=603 and having 53 more cheeseburgers than hamburgers can be written algebraically as y=x+53.

To solve the system:

x+y=603

y=x+53

Substitute what y equals in the second equation for y in the first equation:

x+(x+53)=603

2x+53=603

-53 -53

2x=550

2 2

x=275 hamburgers

To solve for the number of cheeseburgers, substitute 275 for x in either equation.

y=x+53

y=275+53

y=328 cheeseburgers

To double check your work, make sure that 275+328=603 and that 328=275+53. Since both are true, you have solved for the number of hamburgers (275) and cheeseburgers (328).

Step-by-step explanation:

Answer: 58 cheeseburgers

c = [tex]\sqrt{45}[/tex]

Step-by-step explanation:

According to the Pythagoras' Theorem, the square of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides.

Since the other two sides are 6 and 3, [tex]c^{2}[/tex] = 6 squared + 3 squared.

So, c = the square root of 6 squared + 3 squared

Answer:

x/50=78/100

Explanation:

since the test has 50 points TOTAL, you know that it will be the denominator. and x would be however many points he got on the test. so out of 50 points, the student got x points is what x/50 means. then the second one would be your percentage. when converting percents do decimals, the number of your percent (in this case 78) would be your numerator, and since percents are out of 100 your denominator would be 100

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

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)
