Miles is shopping for a new computer. He finds a computer with an original price of $325. 00 but finds that it is 15% off. After paying a 7% sales tax, how much does miles spend on his new computer?.
Answers
Miles has to spend $295.3375 on his new computer.
Sales tax is applied to the price after the discount is applied because discounts are typically provided directly by the retailer and lower both the sales price and the money the retailer receives.
So Original price of Computer is $325.00
Discount with computer is 15% off.
15% of $325 is (325*15)/100 = $48.75.
Price of computer after discount = 325-48.75 =$276.25
Now sales tax will be applied on this price.
7% sales tax = 0.07
amount of sales tax = 276.25*0.07 = 19.3375
Price of Computer after sales tax = 276+19.3375 = 295.3375.

Answers
If you train 10 distinct models on the same training data, try integrating them into a voting ensemble, which will eventually produce better results.
what is voting ensemble ?Voting is an ensemble technique for making predictions by combining the results of various models. The predictive performance of an ensemble is better than that of a single predictive model in a predictive modeling issue. This is accomplished by the model adding bias, which lowers the variance component of the prediction error

10 post hole that are 3 feet deep and 1 foot across with a pipe down the center that is 3 inches in diameter
Answers
The total volume of all 10 holes and pipes is about 24.135 cubic feet.
What is Volume?Generally, To calculate the volume of the holes, you can use the formula for the volume of a cylinder:
Volume = π * radius^2 * height
In this case, the radius of the hole is 0.5 feet (since the hole is 1 foot across and the diameter of the pipe is 3 inches, which is 0.25 feet), and the height is 3 feet. Plugging these values into the formula, we get:
Volume = π * 0.5^2 * 3 = 0.785 * 3 = 2.355 cubic feet
So each hole has a volume of about 2.355 cubic feet. To find the total volume of all 10 holes, you can simply multiply this number by 10:
Total volume = 2.355 * 10 = 23.55 cubic feet
This is the volume of the holes themselves, not including the volume of the pipes. To find the volume of the pipes, you can use the same formula, but with the radius of the pipe (which is 1.5 inches, or 0.125 feet) and the length of the pipe (which is 3 feet).
Volume = π * 0.125^2 * 3 = 0.0195 * 3 = 0.0585 cubic feet
So the volume of one pipe is about 0.0585 cubic feet. To find the total volume of all 10 pipes, you can multiply this number by 10:
Total volume = 0.0585 * 10 = 0.585 cubic feet
23.55 + 0.585 = 24.135 cubic feet.

Mackenzie ha ome red, yellow and blue marble. She ha 3200 more red marble than yellow marble. She ha 3840 more blue than yellow. She give 1490 blue marble away. How many more red marble than blue marble doe he have left?
Answers
We know that there are 850 more red marbles left than blue marbles by solving equations.
What are equations?The equals sign is used in mathematical equations to indicate that two expressions are equal.
An equation is a claim that demonstrates the equality of two mathematical expressions, according to algebra.
For instance, the word "equal" separates the formulas 3x + 5 and 14, which together form the equation 3x + 5 = 14.
So, a number of red marbles more than blue marbles is:
Mackenzie has 3200 more red than yellow marbles.
y + 3200 = r
Additionally, she has 3840 more blue than yellow marbles.
y + 3840 = b
Assume Mackenzie has one yellow marble, then.
1 + 3200 = 3201 red marbles
1 +3840 = 3841 blue marbles
She will have left over 2351 blue marbles after giving away 1490
3841 - 1490 = 2351
She now has 3201 red marbles and 2351 blue marbles.
r - b =?
3201 - 2351 = 850
Therefore, we know that there are 850 more red marbles left than blue marbles by solving equations.

What transformations were applied to the parent function k(x)=x| to obtain f(x)= -1/2|x+3/-1.
Answers
Answer:
The transformations applied to the parent function k(x)=x| to obtain f(x)= -1/2|x+3/-1 are reflection in the y-axis, vertical stretching by a factor of 1/2, and a horizontal shift of 3 units to the right.
Step-by-step explanation:
To obtain f(x) from k(x), we first reflect k(x) in the y-axis, which changes the sign of the function and flips it over the x-axis. This gives us -k(x). Next, we vertically stretch the graph of -k(x) by a factor of 1/2. This makes the graph of -k(x) taller and narrower. Finally, we shift the graph of -k(x) 3 units to the right. This moves the entire graph 3 units to the right on the x-axis. The resulting function is f(x)=-1/2|x+3/-1.To understand why these transformations were applied, it's helpful to consider the effect of each transformation on the graph of k(x)=x|. Reflecting in the y-axis flips the graph over the x-axis and changes the sign of the function, so it becomes -k(x). Vertical stretching by a factor of 1/2 makes the graph of -k(x) taller and narrower. Finally, shifting the graph of -k(x) 3 units to the right moves the entire graph 3 units to the right on the x-axis. This results in the graph of f(x)=-1/2|x+3/-1.
Answer:
(Assuming it is k(x) = |x| and f(x) = -1/2|x+3| -1
Scale vertically by a factor of -1/2
Shift left 3
Shift down 1
Step-by-step explanation:
The -1/2 is multiplied by everything, so it scales the graph vertically by -1/2. The -1 is again, everything(as opposed to just modifying the x), so it shifts the graph down by 1.
The + 3 is a little more confusing. Basically, x would have to be x-3(which is shifting the graph left) in order to retain the same x-value(to make the equation true) for the same value. This is the same for y, but we usually isolate y so it doesn't come up as often. If we add 1 to both sides, we get [tex]f(x) + 1= -1/2|x+3|[/tex], and for the same reasoning the graph would shift down 1 even though it is f(x) + 1, because for the same x-value the y-value would need to be 1 less to make the equation to hold true.

Answers
The amount of money that Noah needs to invest would be = $ 6,558
What is interest rate?An interest rate is defined as the rate at which an individual receives an interest on an invested funds over a stipulated period of time.
The interest rate (R) = 7% = 0.07 (decimal form)
The time for the investment (T) = 10 years.
The present value of the account (A) = $12,900
n compounding frequency = 1
Using the formula;
A = P (1 +r/n) ^nt
12,900 = P ( 1 + 0.07) ^ 10
12,900 = P (1.07) ^10
12,900 =P 1.96715

The given scenario can be modelled as an exponential equation.
Let y be the area the fire covers (in meters squared).
Let x by the time (in hours).
If the fire currently covers an area of 32 m² then the initial value, a, is 32.
If the area covered by the fire increases by 17% each hour, then the growth factor, b, is 1.17 (since an increase of 17% is 117% of the previous amount).
Therefore:
a = 32b = 1.17Substitute the values of a and b into the exponential formula:
[tex]y=32(1.17)^x[/tex]
To find the area that the first covers in 20 hours' time, simply substitute x=20 into the equation:
[tex]\implies y=32(1.17)^{20}[/tex]
[tex]\implies y=32(23.1055991...)[/tex]
[tex]\implies y=739.37917...[/tex]
Therefore, the area the fire will cover in 20 hours' time is 739 m² (nearest 1 m²).

Algebra: What Is It?Mathematical branch known as algebra deals with symbols and arithmetic operations on them. These symbols are referred to as variables because they lack fixed values. We frequently observe certain values that change in our day-to-day problems. However, there is a continuing need to depict these shifting values. These values are frequently represented in algebra by symbols, which are known as variables, such as x, y, z, p, or q.
Take into account all positive numbers that are multiples of 10 and have a value lower than or equal to 200.
Let x be the quantity of positive integers that are multiples of 10. The equation then becomes
10x ≤ 200
The value of the x will then be.
x ≤ 20
Below is a list of the numbers.
Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}
The set that can be divided by 15 is

We sometimes need to apply a permutation to calculate the overall number of outcomes. A permutation is a method for calculating the number of events that occur when order is important.
Given,
Connection of roads from a = 6
Connection of roads from a = 4
Number of roads from a to b =6
Number of roads from b to c =4
Number of ways can a person travels from a to c via b
= 6*4
= 24 ways
The number of ways a person can go from A to C via B is 24.
