Can any decimal thta end with a digit in the hundreth place can be written a a fraction with the denominator that i diviible by both 2 and 5?
It is true that any decimal with a thousandths place digit may always be expressed as a fraction with a denominator that is divisible by both 2 and 5.
A fraction is used to denote a portion or component of a whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.To convert a decimal to a fraction, you can place the decimal over a power of 10 that makes the decimal equal to the fraction. For example, to convert 0.25 to a fraction, you can place it over 100:
\(0.25=\frac{25}{100}\)
Since both 2 and 5 divide evenly into 100, the denominator of the fraction is divisible by both 2 and 5.
This same process can be applied to any decimal that ends with a digit in the hundredth place to convert it to a fraction with a denominator that is divisible by both 2 and 5.
Therefore, it's true any decimal that ends with a digit in the hundredth place can be written as a fraction with a denominator that is divisible by both 2 and 5.

Which formula correctly shows how to find the 21st term in the geometric sequence?
2000, 1000, 500, 250, 125, ...
Answer: Therefore, the correct formula is {a}_{21} = 2000 * 0.5^{20}.
Step-by-step explanation:
A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the previous term by a constant factor called the common ratio. In this case, the common ratio is 0.5, since each term is found by dividing the previous term by 2.
To find the nth term in a geometric sequence, we can use the formula:
a_n = a_1 * r^(n-1)
where a_1 is the first term in the sequence, a_n is the nth term, and r is the common ratio. In our case, the first term is 2000, the nth term is the 21st term, and the common ratio is 0.5. Therefore, the formula we need to use is:
a_21 = 2000 * 0.5^(21-1)
= 2000 * 0.5^20
Therefore, the correct formula is {a}_{21} = 2000 * 0.5^{20}.

The probability associated with obtaining a particular value of z is referred to as its statistical probability or simply its probability. It represents the likelihood of observing a specific value of z in a given statistical distribution.
The probability of a specific value of z can be calculated using various statistical methods, depending on the distribution being considered. In statistics, z represents a standard score or a z-score. It is a measure of how many standard deviations a particular value is away from the mean of a distribution. The probability associated with a specific value of z is determined by the characteristics of the distribution, such as its shape, mean, and standard deviation. Different distributions, such as the normal distribution or the t-distribution, have different methods for calculating probabilities associated with specific values of z.
The probability associated with a particular value of z can be useful in hypothesis testing, confidence interval estimation, or determining the likelihood of an event occurring. By understanding the probability distribution of z-values, statisticians can make informed decisions and draw conclusions based on data analysis.

Step-by-step explanation:
the density of ethanol is 1.09g/cm^3 the density of propylene is 0.97g/cm^3 80 litres of ethanol are mixed with 148 litres of propylene to make 228 litres of antifreeze work out the density of the antifreeze in g/cm^3
Answer:
The density of the final mixture is 1.012 g/cm³.
Step-by-step explanation:
To calculate the density of the final mixture we need to know the mass of each solution used is. We will also need to convert the volumes from litres to cm³, to do that we can just multiply 1000.
For the ethanol:
\(mass = volume*density\\mass = (80*1000)*1.09 = 87,200 \text{ g}\\\)
For the propylene:
\(mass = (148*1000)*0.97 = 143,560 \text{ g}\)
So the mass in the final mix is the sum of both:
\(mass_{final} = 87200 + 143560 = 230,760 \text{ g}\)
Therefore the density is:
\(density_{final} = \frac{230760}{228000} = 1.012 \text{ }\frac{g}{cm^3}\)
The density of the antifreeze is 1.01 g/cm³
Equations are used to show the relationship between two or more numbers and variables.
Let x represent the density of the antifreeze in g/cm^3.
1 cm³ = 0.001 L
80 L = 80000 cm³; 148 L = 148000 cm³, 228 L = 228000 cm³
Hence:
(1.09 * 80000) + (0.97 * 148000) = x * 228000
228000x = 230760
x = 1.01 g/cm³
The density of the antifreeze is 1.01 g/cm³

Find the value of z such that 0.15 of the area lies to the right of z.
The value of z such that 0.15 of the area lies to the right of z is approximately 1.04.
To find the value of z such that 0.15 of the area lies to the right of z, you'll need to use the standard normal distribution table or a calculator with the inverse cumulative distribution function.
Step 1: Identify the given information. The area to the right of z is 0.15.
Step 2: Calculate the area to the left of z. Since the total area under the standard normal curve is 1, the area to the left of z is 1 - 0.15 = 0.85.
Step 3: Find the z-value that corresponds to the area of 0.85 using a standard normal distribution table or calculator. Look up the value 0.85 in the table or use the inverse cumulative distribution function on a calculator (often denoted as invNorm or Φ^(-1)).
Step 4: The value of z corresponding to an area of 0.85 is approximately 1.04.

The cost to make each T-shirt is $10. You estimate that you will
sell 50 shirts. If you want to make a profit of at least $250, what
price will you charge for these T-shirts? Show your solution in two
different ways.
The price per T-shirt should be at least $15 to achieve a profit of $250.
To calculate the price per T-shirt that will yield a profit of at least $250, we need to consider the cost of production, the desired profit, and the number of shirts to be sold.
Given that the cost to make each T-shirt is $10, and we want to sell 50 shirts, the total cost of production would be 10 * 50 = $500.
Now, let's calculate the minimum revenue needed to achieve a profit of $250. We add the desired profit to the total cost of production: $500 + $250 = $750.
Finally, to determine the price per T-shirt, we divide the total revenue by the number of shirts: $750 ÷ 50 = $15.
Therefore, to make a profit of at least $250, the price per T-shirt should be set at $15.
By selling each T-shirt for $15, the total revenue would be $15 * 50 = $750. From this revenue, we subtract the total production cost of $500 to calculate the profit, which amounts to $750 - $500 = $250. Thus, by charging $15 per T-shirt, the desired profit of $250 is achieved.

Line diagram is given by Anode: Cd(s) | Cd²+(aq) || PdCl(aq), Cl-(aq) | Pd(s)
The measured standard cell potential is an important parameter used to describe a cell's ability to produce an electric current. In this case, the cell you are referring to is used to purify palladium. To write the line diagram for the cell, we need to understand the components involved in the reaction. The given reaction equation shows that the cell consists of the following:
1. PdCl(aq): This represents a solution of palladium chloride.
2. Cd(s): This represents a solid cadmium electrode.
3. Pd(s): This represents a solid palladium electrode.
4. Cl(aq): This represents chloride ions in solution.
5. Cd²+ (aq): This represents cadmium ions in solution.
Now, let's arrange these components in the line diagram. The anode is the electrode where oxidation takes place, and the cathode is where reduction takes place. In this reaction, cadmium (Cd) is being oxidized, so it is the anode. Palladium (Pd) is being reduced, so it is the cathode.
Here is the line diagram for the cell:
Anode: Cd(s) | Cd²+(aq) || PdCl(aq), Cl-(aq) | Pd(s)
The vertical lines represent phase boundaries, and the double vertical line represents the salt bridge or the barrier between the two half-cells. The half-cell on the left is the anode, and the half-cell on the right is the cathode. The salt bridge allows the flow of ions to maintain charge balance.

what happens to an inequality sign when the inequality is multiplied or divided by a negative number
When an inequality is multiplied or divided by a negative number, the inequality sign will flip, meaning it will change its direction. For example, if you have a > b and you multiply or divide both sides by a negative number, the inequality will become a < b. This is because the relationship between the values reverses when multiplied or divided by a negative number.
Explanation:
When an inequality is multiplied or divided by a negative number, the direction of the inequality sign is flipped. This is because multiplication or division by a negative number, results in a reversal of the order of the numbers on the number line.
To see why this happens, consider the following example:
Suppose we have the inequality x < 5. If we multiply both sides of this inequality by -1, we get -x > -5. Notice that we have flipped the inequality sign from "<" to ">". This is because multiplying by -1 changes the sign of x to its opposite, and also changes the sign of 5 to its opposite, resulting in a reversal of the order of the numbers on the number line.
Similarly, if we divide both sides of the inequality x > 3 by -2, we get (-1/2)x < (-3/2). Here, we have again flipped the inequality sign from ">" to "<". This is because dividing by a negative number also changes the order of the numbers on the number line.
In general, if we have an inequality of the form a < b or a > b, where a and b are real numbers, and we multiply or divide both sides by a negative number, we obtain:
If we multiply by a negative number, the inequality sign is flipped. For example, if a < b and c < 0, then ac > bc.
If we divide by a negative number, the inequality sign is also flipped. For example, if a > b and c < 0, then a/c < b/c.
Therefore, it is important to be mindful of the signs of the numbers involved when performing operations on inequalities. If we multiply or divide by a negative number, we must flip the direction of the inequality sign accordingly.

Answer:
2 50ml bottles
Step-by-step explanation:
Reading through the question, we have:
For 80mL
\(C_1 = \pounds 55\)
For 2 50mL bottles.
The cost is calculated by the original cost + half the original cost.
i.e.
\(C_2 = \pounds 45 + \frac{1}{2} * \pounds 45\)
\(C_2 = \pounds 45 + \pounds 22.5\)
\(C_2 = \pounds 67.5\)
Next, is to calculate the unit price of each.
For 80mL
\(C_1 = \pounds 55\)
\(Unit\ price = 55/80\)
\(Unit\ price = 0.6875\)
For 2 50mL bottles.
\(C_2 = \pounds 67.5\)
\(Unit\ price - 67.5/(2 * 50)\)
\(Unit\ price = 67.5/100\)
\(Unit\ price = 0.675\)
By comparison, the 2 50mL is the best buy because it has smaller unit price

The concept of the integral is a fundamental part of calculus and it is used to calculate the area under a curve or the volume of a 3-dimensional object. In this context, we will be exploring the integral of a two-dimensional set in the R^2 plane.
For every two-dimensional set C contained in R^2 for which the integral exists, the function Q(C) is defined as the double integral of the function (x^2 + y^2) over the set C. The double integral is a mathematical tool for finding the total volume under a surface.
Let's consider the three sets C1, C2, and C3 and find Q(C1), Q(C2), and Q(C3).
C1={(x,y) : −1 ≤ x ≤ 1, −1 ≤ y ≤ 1}
Q(C1) = ∬C1 (x^2 + y^2) dxdy = ∫^1_{-1}∫^1_{-1} (x^2 + y^2) dxdy = ∫^1_{-1} [(x^2 + y^2)/2]^1_{-1} dx = 4.
C2 ={(x,y):−1≤x≤1,−1≤y≤1}
Q(C2) = Q(C1) = 4.
C3 = {(x,y):x^2 + y^2 ≤1}
Q(C3) = ∬C3 (x^2 + y^2) dxdy = π.
