Answer:
Step-by-step explanation: The price after markup was 50% of the original price. To calculate this, first find the discounted price of the couch, which is 25% of $420, or $105. Then add 25% of the discounted price to the discounted price, which is $105 + (25% x $105) = $131.25. Finally, divide the price after markup by the original price to calculate the percent of the original price: $131.25 / $420 = 31.2%. Rounded to the nearest whole number, this is 50%.

How do I simplify Rational Exponents and Radicals?
I was absent yesterday and we completely moved onto a brand new subject. I don't quite understand, this isn't asking me to solve it, It's asking me to simplify it. help??
Some of the problems I don't understand:
4x⁻⁴y⁴
-2x⁴y⁻¹
Rational exponents and radicals are simplified in a similar way to how other exponents and radicals are simplified.
For the first expression 4x⁻⁴y⁴, you can simplify it by noticing that it has a negative exponent on the x term and a positive exponent on the y term. To simplify, you can keep the base (x and y) and the exponent (4 and -4) but you change the negative exponent to a fraction and change the sign:
4x⁻⁴y⁴ = (x^-4) (y^4) = x^-4y^4
For the second expression -2x⁴y⁻¹, you can simplify it by noticing that it has a negative exponent on the y term. To simplify, you can keep the base (x and y) and the exponent (4 and -1) but you change the negative exponent to a fraction and change the sign:
-2x⁴y⁻¹ = -2 (x^4) (y^-1) = -2x^4y^-1
To simplify these expressions further, you would need to know the specific values of x and y. But these are the steps to simplify a rational exponent or radical to its simplest form.
It's also worth mentioning that if you have a fractional exponent you can simplify it by raising the base to the numerator of the exponent and the denominator of the exponent. For example, x^(3/4) = (x^3)^(1/4) = ∛x
Keep in mind that when you simplify rational exponents or radicals, you should always keep the base and the exponent, and only change the sign of the exponent if it is negative.
Can someone pls help?!

Cubes needed to fill Prism 6:_____cubes
Volume of Prism 6: _______cubic units. (sorry if the pic is messy.) HELP ME I need to FINISH TONIGHT I'm GIVING OUT 30 POINTS!!!!!!
Answer:
125 cubic units
Step-by-step explanation:
the volume formula is length x width x height.
because the length, width, and height of the prism are all 5 units, the volume of the prism is 125 cubic units.
hope this helped, good luck!
Match the terms to their definition. 1 . a number that is less than zero positive number 2 . a number belonging to the set made up of the counting numbers: 1, 2, 3, and so on integer 3 . a number that is greater than zero negative number 4 . a number belonging to the set made up of the whole numbers and their opposites opposite numbers 5 . a line that graphically represents all numbers natural number 6 . two numbers that are the same distance from zero on the number line, but in opposite directions number line
Answer: 1. Negative number
2. Natural number
3. Positive number
4. Integers
5. Number line
6. Opposite numbers
Step-by-step explanation:
1. The first statement says a number that is less than zero, which means any negative number would be less than zero. For example (-1), (-2), etc.
2. The second statement is asking for numbers belonging to the counting set, which means starting from one (1). Natural numbers are numbers that start from 1 and don't include negative numbers or zeros.
3. The third statement says the number that is greater than zero, as negative numbers are smaller than zero and the natural number option has already been chosen above, we will consider positive numbers.
4. Whole numbers consist of both negative and positive integers including zero. Therefore, a set of whole numbers will be written as integers.
5. Number line is a line that represents both negative and positive numbers.
6. Consider an example- (+5) and (-5), both the numbers are the same but with different signs, making them opposite of each other. Therefore, the correct answer would be opposite numbers.

Consider the standard form of an exponential function:
[tex]y=a(b)^x[/tex]
How does changing the base number (inside the parentheses) change your graph?
Answer:
Step-by-step explanation:
Challenge 1
We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.
If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.
Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).
Remember that b cannot be negative.
===========================================
Challenge 2
In the general template provided, enter x = 0.
y = a(b)^x
y = a(b)^0
y = a(1) (1)
y = a
When x = 0 is plugged in, the result is y = a.
The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.
Examples:
