Answer: 120
120
Step-by-step explanation:
I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)
P/w = part/whole = ?/400
%/100= percent/100 = 30%/100
These numbers are equivalent
If you don’t understand the top then here is how to do the work-
400x30=12000
12000/100=120
Therefore it’s 120

Can yall give me 4 examples of rules of exponents with answers pls?
Answers
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
[tex]a^{x} * a^{y} = a^{x+y}[/tex]
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
[tex]a^{x} / a^{y} = a^{x-y}[/tex]
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
[tex](a^{x)^{y} } = a^{xy}[/tex]
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
[tex](ab)^{x} = a^{x} b^{x}[/tex]

General Formulas and Concepts:
Order of Operations: BPEMDASEquality PropertiesDistributive PropertyStep-by-step explanation:
Step 1: Define equation
[tex]q=p(r+s)[/tex]
Step 2: Solve for r
Distribute p: [tex]q=pr+ps[/tex]Subtract ps on both sides: [tex]q-ps=pr[/tex]Divide both sides by p: [tex]\frac{q-ps}{p} =r[/tex]Rewrite: [tex]r=\frac{q-ps}{p}[/tex]Step-by-step explanation: To solve for r, start by distributing the p
through the parentheses on the left side to get q = pr + ps.
Next, isolate the r term by subtracting ps from both sides to get -ps + q = pr.
Finally, to get r by itself, divide both sides by p and we have -ps + q/p = r.

Mrs. Kelly bought a bag of flour that holds 1623 cups of flour. Each loaf of banana bread uses 23 cup of flour.
How many loaves of banana bread can she make?
Answers
Answer:
69 loaves
Step-by-step explanation: (Sorry if you don't understand I am not that good at explaining)
First you need to divide 1,623 by 23 because each loaf is 23 cups of flour.
So 1,623 divided by 23 equals 70.56 but you can't have a fractioned number so it needs to be a whole loaf of bread so she can make 69 loaves of bread
70.57 loaves of banana bread
Explaintion:
1,623 ➗ 23 = 70.5652173913043
Rounded: 70.57

Answers
Answer:
3/4
Step-by-step explanation:
If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in
1/4(x)=y
1/4(3)=y
3/4=y
And the other one is incorrect
1/4(x)=y
1/4(7)=y
1 3/4 =y

The graph of the function y = 2x⁴ - 5x³ + x² - 2x + 4 is plotted and attached.
What is a polynomial?Polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). For example -
y = 4x⁴ + 3x³ + 2x² + 6x + 7
We have the following polynomial functions -
f(x) = 2ˣ
g(x) = f(x - 3) + 4
We can write g(x) as -
g(x) = 2ˣ ⁻ ³ + 4 = (2ˣ/2³) + 4
g(x) = (2ˣ/8) + 4
The graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards.
Therefore, the graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards to given the function g(x)
