Answer:
The mean saving was $744.54 per hour to fill out Schedule A tax form.
Step-by-step explanation:
Given that:
Time taken by Rodriguez family = 5.5 hours
Amount saved in taxes = $4095
5.5 hours = $4095
The mean savings per hour can be calculated by dividing the total hours taken by the amount saved in taxes.
1 hour = [tex]\frac{4095}{5.5}\\[/tex]
1 hour = $744.54
Savings per hour = $744.54
Hence,
The mean saving was $744.54 per hour to fill out Schedule A tax form.

Consider the function f(x) = x2 + 2x – 15. What are the x-intercepts of the function?
Answer:
The x-intercepts of the function are [tex]x = 3[/tex] and [tex]x = -5[/tex].
Step-by-step explanation:
We are given the function [tex]\displaystyle f(x) = x^2 + 2x - 15[/tex].
In order to find the x-intercepts of the equation, we need to solve this quadratic. We can use factoring methods to solve it.
The parent function for a quadratic is [tex]f(x) = ax^2 + bx + c = 0[/tex].
We can use this information to determine what factoring technique we want to use.
There are several different methods, including using the quadratic formula, but because this is easily factorable, we can avoid using it.
We see that our a is equal to 1 (there is no coefficient in front of x²), so we can use the easier of the techniques:
Find what factors of c add up to give you b.Add to x if positive or subtract from x if negative and set it equal to zero.Solve for x - these are your x-intercepts.Therefore, let's determine what our c is: 15.
Now, let's label the factors for 15.
15 cannot be divided by 2 evenly.15 can be divided by 3 evenly: 15/3 = 515 cannot be divided by 4 evenly.15 can be divided by 5 evenly: 15/5 = 3Therefore, our two factors are 3 and 5 since they cannot be broken down any further (they are prime numbers - we just performed prime factorization).
Now, we need to pay attention to the sign for c. It's negative, so one of our factors needs to be negative. Therefore, we can test this out:
[tex]5 + -3 = 2[/tex][tex]-5 + 3 = -2[/tex]Now, we check for which one matches the sign for b. This is positive 2, so our two factors are 5 and -3.
Finally, to factor, we add or subtract the factors from x depending on the sign. If the factor is positive, we add it. If the factor is negative, we subtract it. Therefore, we can set up our equations.
[tex]x + 5 = 0\\\\x = -5[/tex]
[tex]x - 3 = 0\\\\x = 3[/tex]
Therefore, for when x = 3 or x = -5, the line crosses the x-axis. These are the x-intercepts of the function.
Our answers are x = -5 and x = 3.

Step-by-step explanation:
the number is 96
hence,
25% of 96=
25/100*96/1
=24
50% of 24=
50/100*24/1=
12
it also possible that you're to sum them,but since you were not asked for the sum of the number the answer is 12.
Answer:
768
Step-by-step explanation:
1. Try converting percentage into fractions and simplify them:
50%*25*n=96
of=multiplication
1/4*1/2*n=96
2. Multiply the fractions:
1/4*1/2=1/8
1/8*n=96
Other people say "Can you finish it?", but if you don't know, I'll finish it.
96*8=768
Therefore, the answer is 768.
Which of the following statements best explains why this graph represents a relation that is not a function
Answer:
i think it’s “ the x values between 1 & 3 are each paired with multiple y values “
Step-by-step explanation:
The given relation is not a function because input value 1 and 3 have more than one value
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
As, we know if the relation is function then it's input value is distinct.
From the graph we can se that the input value 1 and 3 have more than one value
As, input 1 ----> {1.1, -1.1}
and, input 3 ----> {0, -2.5}
Hence, the given relation is not a function.

Latrell took one of his friends out to lunch. The lunches cost $60 and he paid 5% sales tax. If Latrell left a 15% tip on the $60, how much in total did he pay?
Answer:
$72
Step-by-step explanation:
Cost of the lunch = $60
Sales tax = 5% of $60
= 5/100 × 60
= 0.05 × 60
= $3
Tip = 15% of $60
= 15/100 × 60
= 0.15 × 60
= $9
how much in total did he pay?
Total amount paid = cost of the lunch + sales tax + tip
= $60 + $3 + $9
= $72
Latrell paid $72 in total for the lunch

In Δ A B C, the measure of the largest angle is 32 less than 3 times the smallest angle. The measure of the middle angle is 8 more than half the measure of the largest angle. What is the measure of the middle angle?
Answer:
52degrees
Step-by-step explanation:
Let the measure of the largest angle be x
middle angle be y
smallest angle be z
Since the sum of angle in a triangle is 180 degrees, hence;
x + y + z = 180 .... 1
If the measure of the largest angle is 32 less than 3 times the smallest angle, then;
x = 3z - 32
3z = x+ 32
z = x+32/3 ..... 2
If he measure of the middle angle is 8 more than half the measure of the largest angle, then;
y = x/2 + 8 .... 3
Substitute 2 and 3 into 1;
x + x/2 + 8 + (x+32)/3 = 180
multiply through by 6
6x + 3x + 48 + 2(x+32) = 1080
9x + 48 + 2x + 64 = 1080
11x + 112 = 1080
11x = 1080-112
11x = 968
x = 968/11
x = 88 degrees
Get the middle angle y;
Since y = x/2 + 8
y = 88/2 + 8
y = 44 + 8
y = 52 degrees
Hence the measure of the middle angle is 52degrees
The angles in a triangle add up to 180 degrees.
The middle angle is 52 degrees
Let the largest, middle angle and the smallest angle be x, y and z
From the question, we have:
[tex]\mathbf{x = 3z -32}[/tex]
[tex]\mathbf{y = 8 + \frac 12x}[/tex]
Make z in [tex]\mathbf{x = 3z -32}[/tex]
[tex]\mathbf{z =\frac{x + 32}{3}}[/tex]
The angles in a triangle add up to 180 degrees.
So, we have:
[tex]\mathbf{x + y + z = 180}[/tex]
Substitute the expressions for y and z in [tex]\mathbf{x + y + z = 180}[/tex]
[tex]\mathbf{x + 8 + \frac 12x + \frac{x+32}{3} = 180}[/tex]
Multiply through by 6
[tex]\mathbf{6x + 3x + 48 + 2(x+32) = 1080}[/tex]
[tex]\mathbf{9x + 48 + 2(x+32) = 1080}[/tex]
Open brackets
[tex]\mathbf{9x + 48 + 2x + 64 = 1080}[/tex]
Evaluate like terms
[tex]\mathbf{11x + 112 = 1080}[/tex]
Subtract 112 from both sides
[tex]\mathbf{11x = 968}[/tex]
Divide both sides by 11
[tex]\mathbf{x = 88}[/tex]
Substitute 88 for x in [tex]\mathbf{y = 8 + \frac 12x}[/tex]
[tex]\mathbf{y = 8 + \frac{88}2}[/tex]
[tex]\mathbf{y = 8 + 44}[/tex]
[tex]\mathbf{y = 52^o}[/tex]
Hence, the middle angle is 52 degrees

Step-by-step explanation:
The inverse of the given function is (6x + 2)/3.
What is the inverse of a function?"The inverse of a function is a function that undoes the operation of that function. The inverse of a function exists if and only if the function is bijective"
Given function is
F(x) = (3x - 2)/6
⇒ y = (3x - 2)/6
If we write 'x' instead of 'y' and 'y' instead of 'x', then we get:
x = (3y - 2)/6
⇒ 6x = (3y - 2)
⇒ 3y = 6x + 2
⇒ y = (6x + 2)/3
Therefore, F⁻¹ (x) = (6x + 2)/3

The shape is composed of three squares and two semicircles. Select all the expressions that correctly calculate the perimeter of the shape. #2 Group of answer choices 80+20π 40+20π 10+10+10π+10+10+10π 120+20π 300+100π
Answer:
120 + 20π
Step-by-step explanation:
Find the image of the question attached.
For the square;
Perimeter of a square = 4L
L is the side length of the square
From the diagram, L = 10
Perimeter of a square = 4(10) = 40
Perimeter of 3 squares = 3(40) = 120
For the semicircles:
Perimeter of a semicircle = 2πr/2 = πr
From the diagram;
L = radius of the semicircle = 10
Perimeter of a semicircle = π(10)
Perimeter of a semicircle = 10π
Perimeter of the two semicircles = 2(10π) = 20π
perimeter of the shape = perimeter of 3squares + 2 semicircles
perimeter of the shape = 120 + 20π
