Answer:
Cost of the computer before taxes is $1299.
Step-by-step explanation:
Let the price of the computer before taxes is = $x
Tax rate on this computer = 7%
Therefore, computer cost including tax = (x + 7% of x)
= [tex]x+\frac{7x}{100}[/tex]
= x + 0.07x
= $(1.07x)
Cost of the computer including tax is given as $1389.93.
Therefore, 1389.93 = 1.07x
x = [tex]\frac{1389.93}{1.07}[/tex]
= $1299
Cost of the computer before taxes is $1299.
How many more people attended the Magic's games than attended the pacers' games? 582,295 pacers 715,901 magic
Answer:
133606 persons
Step-by-step explanation:
Number of persons attended the Magic's game= 715,901 games
Number of persons attended the Pacer's game= 582,295 persons
We have to find the number of persons who attend the Magic's game more than Pacer's game.
To find this, we have to find the difference
Number of persons attended the Magic's game= 715,901 games
Number of persons attended the Pacer's game= 582,295 persons
Number of persons who attended More Magic's game= 715901- 582295
Number of persons who attended More Magic's game= 133606 persons
Hence, the correct answer is 133606 persons

What is the difference between the ratio AP:PB and the ratio of AP:AB?
A line segment can be divided into subsegment using ratios. The difference between [tex]AP:PB[/tex] and [tex]AP: AB[/tex] is that:
Ratio [tex]AP:PB[/tex] compares the two subsegments of AB while Ratio [tex]AP: AB[/tex] compares a segment of AB to the whole length of AB.Given:
[tex]AP:PB[/tex] and [tex]AP: AB[/tex]
In [tex]AP:PB[/tex], we can see that AP and PB has a common point (P).
This means that:
[tex]AB = AP + PB[/tex]
i.e. AP and PB are two subsegments of line segment AB.
So, the ratio [tex]AP:PB[/tex] compares the two subsegments of AB
Because AP and PB are two subsegments of line segment AB.
Then, ratio [tex]AP: AB[/tex] compares a segment of AB to the whole length of AB.

What is the average rate of change from x=-1 to x=2? -3, -1, 1, 24
The average rate of change of the given function from x = -1 to x = 2 is -1.
The average rate of change of a function between two points, x = a and x = b, is calculated as the difference in the function values at these points divided by the difference in x-values, which is similar to the slope formula for a linear function (gradient).
In this case, we are looking for the average rate of change of f(x) = x^4 - 2x^3 from x = -1 to x = 2. Using the table provided:
f(-1) = 3
f(2) = 0
So, the average rate of change is:
(f(2) - f(-1)) / (2 - (-1)) = (0 - 3) / (2 - (-1)) = (-3) / 3 = -1.

The difference between the mean and median of the data is 50.
What is the mean?The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.
Given:
David played a video game 5 times.
The list shows his scores:
4975,5275,4825,5100,4950.
To find the median:
The median is the value that splits the mathematical numbers or expressions in the half. The median value is the middle number of data points. To find the median, firstly arrange the data points in ascending order.
4825, 4950, 4975, 5100 and 5275.
So, the middle number is 4975.
The median is 4975.
To find the mean;
The mean = the sum of the scores / 5
The mean = 25125 / 5
The mean = 5025
The difference:
5025 - 4975 = 50
Therefore, the required difference is 50.

Monique Fournier deposited $12,500 into a savings account paying 6.5% annual interest compounded monthly. What amount will she have in her account after 3 years
Follow below steps;
Monique Fournier wants to find out how much her $12,500 savings account, with an annual interest rate of 6.5% compounded monthly, will grow to after 3 years. To calculate the future value of this investment, we can use the compound interest formula:
FV = P times (1 + r/n)^(nt)
Where:
FV is the future value of the investmentP is the principal amount ($12,500)r is the annual interest rate (6.5% or 0.065 as a decimal)n is the number of times interest is compounded per year (12, since it's compounded monthly)t is the number of years the money is invested (3 years)Plugging the numbers into the formula gives us:
FV = $12,500 times (1 + 0.065/12)^(12 imes 3)
After calculating, Monique's account balance after 3 years will be:
FV = $12,500 times (1 + 0.0054167)^(36)
FV = $12,500 times 1.0054167^36
FV ≈ $12,500 times 1.214669
FV ≈ $15,183.36
After 3 years, Monique Fournier will have approximately $15,183.36 in her savings account

If the shadow of a tree is 14 m long and the shadow of a person who is 1.8 m tall is 4 m long, how tall is the tree?
Which of the following proportions could not be used to solve the problem?
a: 14/1.8=x/4
b: x/14=1.8/4
c: x/1.8=14/4
Answer: [tex]\frac{x}{14}=\frac{1.8}{4}[/tex]
Step-by-step explanation:
Let 'x' be the height of tree.
The length of shadow of a tree = 14 m
The length of shadow of a person =4 m
The height of person = 1.8 m
Since both man and tree are standing vertical to the ground.
Assume the formation of shadow is happening at the same time then the angle that the sun hits the earth making shadows of both person and tree will be equal.
By direct proportion , we have
[tex]\frac{\text{height of tree}}{\text{length of shadow of tree }}=\frac{\text{height of person}}{\text{length of shadow of person}}\\\\\Rightarrow\frac{x}{14}=\frac{1.8}{4}[/tex]
The correct answer would be:
14/1.8 = x/4

1.) 0.024
2.) 2.4
3.) 240
4.) 10^4
5.) 10^5
6.) 10^13
___ x ___ times larger
Final answer:
The population of China is approximately 240 times larger than the population of the Marshall Islands. This is calculated by dividing China's population (1.446×[tex]10^9[/tex]) by the Marshall Islands' population (6.025×[tex]10^4[/tex]). (Option 3)
Explanation:
The question asks us to determine how many times larger China's population is compared to the population of the Marshall Islands. To find the answer, we divide the population of China by the population of Marshall Islands:
1.446×[tex]10^9[/tex] (China's population) ÷ 6.025×[tex]10^4[/tex] (Marshall Islands' population).
Carrying out this division, we get a result of approximately 240 times larger. Thus, the population of China is 240 times larger than that of the Marshall Islands.

Which number line correctly shows 4.5 – 2.5?
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
[tex]4.5-2.5[/tex]
According to the number line,
First we go 4.5 units towards the positive axis of x from the origin.
And then back by 2.5 units from there towards the negative axis of x to show the subtraction.
So, it will interpretate the subtraction of 2.5 from 4.5.
Numerically, it is expressed as
4.5-2.5=2
So, It should reach at 2 in the positive axis of x.
Hence, First option is correct.
A number line that correctly shows 4.5 – 2.5 is: A. number line A.
What is a number line?In Mathematics and Geometry, a number line refers to a type of graph that is composed of a graduated straight line, which typically comprises both negative and positive numerical values (numbers) that are located at equal intervals along its length.
This ultimately implies that, every number line would primarily increase in numerical value towards the right from zero (0) and decrease in numerical value towards the left from zero (0).
Based on the information provided above, we have:
4.5 - 2.5 = 2.
