The Rodriguez family took 5.5 hours to gather information for their Schedule A. The itemized deductions saved them $4,095 in taxes. What was the mean savings per hour to fill out Schedule A tax form?
Answers
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.

how do you change a rational number to a decimal? give an example
Answers
Answer:
If the rational number is a fraction (of course) divide it. For example, 1/2 can be divided as 1 divided by 2 which is 0.5.
If the number is an integer, you can simply just add .0 (point zero). For example, if the rational number is 12, the decimal version would be 12.0.
If the number is a fraction, you can divide the numerator by the denominator. For example, if the rational number is 1/10 (one tenth), just can divide one by zero to get 0.1 (zero point one).

A sergeant received an order to relocate the squad from its current location T (3, -2) on the coordinate plane to a new location S. The movement of the squad is described by the translation (x, y)⟶(x-4, y+6). What are the coordinates of the new location S of the squad?
Answers
Answer:
(-9,-2)
Step-by-step explanation:
The translated coordinates are (-1,4).
What is translation?The process of changing the location of the image on the coordinate system will be known as the translation. The translation is done on the coordinate plane a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Given that A sergeant received an order to relocate the squad from its current location T (3, -2) on the coordinate plane to a new location S. The movement of the squad is described by the translation (x, y)⟶(x-4, y+6).
The translated points will be calculated as below:-
( 3, -2 ) ⇒ [ ( 3 - 4 ) , ( -2 + 6 ) ]
( 3, -2 ) ⇒ [ ( -1 ) , ( 4 ) ]
Therefore, the translated coordinates are (-1,4).

Does 3x-2=2x-3have infinitely many solutions
Answers
Hi there! :)
[tex]\large\boxed{\text{One solution: x = -1}}[/tex]
3x - 2 = 2x - 3
Subtract 2x from both sides:
3x - 2x - 2 = 2x - 2x - 3
x - 2 = - 3
Add 2 to both sides:
x - 2 + 2 = -3 + 2
x = -1
Therefore, the equation only has ONE solution.

One number is three more than the second number. Twice the first is nine less than three times the second. What are the two numbers?
Answers
Answer:
16 and 13
Step-by-step explanation:
Let the second no is x
First no = x+3
Twice the first is nine less than three times the second.
We can write in the form of equation as follows :
2(x+2) = 3x-9
Solving brackets first
2x+4=3x-9
Taking like terms together
9+4=3x-2x
13=x
First no = x+3 = 13 + 3 = 16
So, first and second numbers are 16 and 13 respectively.
What is the area of the figure down below
Answers
68
Explanation:
So to get this answer you need to split it into smaller shapes. We already have the squares so we know that 3*3 is 9 and then we double that because there are two of them.
So, so far we have 18+x
We need to take the middle shape and split it into two trapezoids.
The area for trapezoids is T=(a+b/2)h
So T= (3+7/2)5
T= 5*5=25
And then we would double that because there are two of them so 50 and then fill it in for x
18+50= 68 is the area of the figure.

Visit lives 5km from the school. She walks 1km at 4km/h and travels the rest of the way by bus at 16km/h. What is the average speed for the whole journey
Answers
Answer:
0.63km/h
Step-by-step explanation:
Step one:
given data
total distance= 5km
velocity of walk= 4km/h
distance covered while walking= 1km
time taken to walk
t1= 4/1
t1= 4hours
Step two:
velocity of bus= 16km/h
distance covered while walking= 5-1= 4km
time taken to walk
t2= 16/4
t2= 4hours
total time = 4+4=8hours
Average speed= total distance/total time taken
average speed= 5/8
average speed=0.63km/h

Rational numbers are basically any number that are not numbers with non-recurring decimals or non-terminating decimals.
-[tex]\frac{2}{5}[/tex] = -0.4
[tex]\frac{1}{2}[/tex] = 0.5

The length and width of a 6-inch by 8-inch photograph are reduced by the same amount to make a new photograph whose area is half that of the original. By how many inches will the dimensions of the photograph have to be reduced?
Answers
Answer:
The dimensions have to be reduced by 2 inches
Step-by-step explanation:
Given that the dimensions are: 6 by 8 inches which means that the area is 48 square inches.
Let x be the amount to make a new photo which is half of the area that means
The new dimensions will be: (8-x) by (6-x) and as the area is half
The area of new photo will be: 48/2 = 24
Putting it mathematically
[tex](8-x)(6-x) = 24\\8(6-x)-x(6-x)=24\\48-8x-6x+x^2=24\\48-14x+x^2=24\\x^2-14x+48-24=0\\x^2-14x+24=0\\x^2-12x-2x+24=0\\x(x-12)-2(x-12)=0\\(x-2)(x-12)=0\\x-2=0 => x=2\\x-12=0 =>x=12[/tex]
Subtracting 12 from both dimensions will make them negative so 12 cannot be the solution.
Hence,
The dimensions have to be reduced by 2 inches
We want to see by how much we must reduce the dimensions of the photograph in order to reduce its area to half. We will find that we must reduce each measure by 2 inches.
The original measures of the photograph are:
length = 6 inwidth = 8 in.Then the area is:
A = (6 in)*(8 in) = 48 in^2
Now we want to define a new length and a new width:
L' = (6 in - n)W' = (8in - n)such that:
A' = L'*W' = 24 in^2
(6 in - n)*(8in - n) = 24 in^2
48in^2 - n*14 in + n^2 = 24 in^2
n^2 - n*14 in + 24in^2 = 0
This is a quadratic equation, we can solve this for n by using Bhaskara's formula, we will get:
[tex]n = \frac{14in \pm \sqrt{(-14)^2 - 4*1*24in^2} }{2*1} \\\\n = 7in \pm 5 in[/tex]
The only solution that makes sense is:
n = 7in - 5in = 2in
This means that we need to reduce each measure by 2 inches.

The population of fish in a lake was approximately 5.4 * 10 ^ 4 in 2012.
The approximate population of fish in this in 2013 since the amount of the fish tripled is 1.62 × 10⁵

Given that:
The approximate number of fish in 2012 is: 5.4 × 10⁴In 2013, when the population of the fish tripled the amount it was in 2012;
Then, we can calculate the total population of fish in 2013 as:
