Which number is greater,
23×10^3
or
11×10^4?
How do you know? Explain your steps.
[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.

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)

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

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

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
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:
