Answer:
384 but see below.
Step-by-step explanation:
Remark
A_n = 3*2^(n - 1) I will assume that's what you mean. I'll give the answer for A_n = 3*2^n - 1 as well.
Solution
n = 8
A_n = 3 *2^(8 - 1)
A_8 = 3*2^7
A_8 = 3* 128
A_8 = 384
If you mean A_n = 3*2^n - 1
Then you would get
A_n =3 * 2^8 - 1
A_8 = 3 * 256 - 1
A_8 = 768 - 1
A_8 = 767

1/4 is 60% of x. Write a proportion that you can use to find x
The required value of x is approximately 0.4167 if 1/4 is 60% of x.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
To write a proportion that we can use to find the value of x, we can use the fact that "1/4 is 60% of x" and set up the proportion:
1/4 = (60/100) × x
Here, we have converted 60% to its equivalent decimal form (0.60) and 100% to its equivalent fraction (1).
We can then cross-multiply to solve for x:
1/4 × 1 = 0.60 × x
1/4 = 0.60x
0.25 = 0.60x
x = (0.25) / 0.60
x ≈ 0.4167
Therefore, the value of x is approximately 0.4167.

Jamie receives 15% commission on magazine subscriptions. One week her sales totaled $860. What was her commission?
Given:
Jamie receives 15% commission on magazine subscriptions.
One week her sales totaled $860.
To find:
Her commission.
Solution:
We have,
Total sales of one week = $860
Rate of commission = 15%
Now,
[tex]Commission=\dfrac{15}{100}\times 860[/tex]
[tex]Commission=\dfrac{15}{10}\times 86[/tex]
[tex]Commission=\dfrac{1290}{10}[/tex]
[tex]Commission=129[/tex]
Therefore, the amount of commission is $129.
If there are 30 boys and 15 girls in the room fill out all the possible ratios of boys to girls that could be made
Answer:
All the possible ratios of boys to girls that could be made are:
30:15
10:5
6:3
2:1
Step-by-step explanation:
If there are 30 boys and 15 girls in the room
We have :
Boys : Girls
30 : 15
a) 30 : 15
Dividing through by 3
= 10:5
b) 30 : 15
Dividing through by 5
= 6:3
c) 30 : 15
Dividing through by 15
= 2:1
Hence:
All the possible ratios of boys to girls that could be made are:
30:15
10:5
6:3

Use the Zero Product Property to find the x-intercepts for x^2+6x=y
Answer:
[tex]x=0\ or\ x =-6[/tex]
Step-by-step explanation:
Given
[tex]x^2+6x=y[/tex]
Required
Determine the x intercepts
To get the x intercepts, we simply set y to 0
Substitute 0 for y;
[tex]x^2+6x=0[/tex]
Factorize:
[tex]x(x +6) = 0[/tex]
Apply zero product property
[tex]x=0\ or\ x + 6 =0[/tex]
[tex]x=0\ or\ x =-6[/tex]

Which one of the following reasons does NOT explain why 2x + 3y ≠ 5xy?
Answer:
Since 2 and 3 are factors, they should be multiplied to get 6xy.
Step-by-step explanation:
The solution is Option B.
Since 2 and 3 are factors, they should be multiplied to get 6xy and the equation is False
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
2x + 3y ≠ 5xy
a)
If you substitute 4 for x and 5 for y in the expression 2x+3y, it does not equal 5(4)(5)
Substituting the value of x = 4 and y = 5 in the equation , we get
2 ( 4 ) + 3 ( 5 ) ≠ 5 ( 4 ) ( 5 )
8 + 15 ≠ 100
23 ≠ 100
Therefore , the statement is True
b)
Since 2 and 3 are factors, they should be multiplied to get 6xy
2x ( 3y ) = 6xy
But the equation does not equals 6xy
Hence , the statement is False and does not explain the given equation
c)
x and y are not like terms
The statement is true because the variables x and y are not the same
Therefore , the statement is True
d)
Adding x and y is not the same as multiplying x and y
The value of the equation x + y = x + y and on multiplying x and y = xy
And , x + y ≠ xy
Therefore , the statement is True
Hence , the equation 2x ( 3y ) = 6xy is False
