The ratio of the number of student in mr. Moore’s class compared to the number of student in miss Henry’s class is 5:4. The ratio of the number students in miss Henry’s class compared to the number of students on mr. Wilson’s class is 8:9. What is the ratio of number of students in mr. Moore’s class to mr. Wilson’s class?
Answer:
10:9
Step-by-step explanation:
First ratio is 5:4. 4 is equal to Henry class
If you múltiply the ratio by 2 you get
10:8, This ratio can be compared because now Henry class has 8
2(5:4)
10:8
8:9
Meaning that the answer is 10:9
The require ratio of number of students in Mr. Moore's class to Mr. Wilson's class is 10:9
What is Ratio?The ratio can be expression as how many times one number contain another number.
For example, If any bag contain 4 apples and 8 oranges then the ratio of apple to orange is 4:8 while the ratio of the orange to the apple is 8:2
How to find ratio?Consider M denote the number student present in the Mr. Moore's class
similarly H denote the number of student in miss Henry's class and W denote the number of student present in Mr. Wilson's class
then we have given that
M : H = 5 : 4 or
\(\frac{M}{H} = \frac{5}{4}\)
Also we have H : W = 8 : 9
\(\frac{H}{W} = \frac{8}{9}\)
Now multiply these two equations we have
\(\frac{M}{H}\times \frac{H}{W}=\frac{5}{4}\times\frac{8}{9}\)
\(\frac{M}{W}= \frac{10}{9}\)
The ratio of number of student in Mr. Moore's class to Mr. Wilson's class is 10:9

You have 2 fruit punch mixtures with you. The first mixture is 70% fruit
punch and the second is 30% fruit punch. If you want 100 gallons of
40% fruit punch mix how many gallons of each punch will you need?
Answer:
25 gallons of the 70% and 75 gallons of the 30%
Step-by-step explanation:
First, make three baskets. One having x, the second having 100-x, and the third having 100. The reason you have 100-x is because you are adding two unknown numbers, and when you add them they equal 100. And if they add to be 100, 100-x=100-x. To continue, under each basket, write the number of the percent. So the first basket would have 70 under it, the second one would have 30 under it, and the third one would have 40 under it. Then multiply the number inside the basket by the number under. Then you would get 70x+3,000+30x=4,000. Next, 40x+3,000=4,000. Then 40x=1,000. x=25. That's the first basket. For the second, you do 100-25 because of the equation inside the second basket, which is 75. Hope this helps!

A figure is shown in the image. What is the measure, in
degrees of
А. 95.4
B. 52.1
C. 74.2
D. 64.7
Answer:
Step-by-step explanation:
angles x, 2x, and 23.7 add up to 180 degrees
x + 2x + 23.7 = 180
3x + 23.7 = 180
subtract 23.7 on both sides
3x + 23.7 - 23.7 = 180 - 23.7
3x = 156.3
divide both sides by 3
x = 52.1
Angle C is a straight line = 180 degrees
Angle B is found by adding 32.5 and x, and subtracting it from 180 degrees (since three angles in a triangle must add up to 180)
we found x = 52.1 degrees
so angle B = 180 - 32.5 - 52.1 = 95.4 degrees

For each graphically defined function below, state the domain, the range, and the intervals over which the function is increasing, decreasing, or constant.
The domain of the function above is [-2, 3].
The range of the function above is [-2.5, 2].
The intervals over which the function is increasing is [-2, 1.5] U [-2.5, 2].
The intervals over which the function is decreasing is [1.5, -2.5].
What is a domain?In Mathematics and Geometry, a domain refers to the set of all real numbers for which a particular function is defined.
Furthermore, the vertical extent of any graph of a function represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.
By critically observing the graph of this rational expression (function) shown in the image attached below, we can reasonably and logically deduce the following domain and range:
Domain = [-2, 3] or -2 ≤ x ≤ 3.
Range = [-2.5, 2] or -2.5 ≤ y ≤ 2.
Additionally, the intervals over which the function is increases over the interval [-2, 1.5] and [-2.5, 2], while it decreases over the interval [1.5, -2.5].
In conclusion, the given function is not constant over any interval.

Answer:
Step-by-step explanation:
To show that the expression \(\ln(\sqrt{2} + 1) - \ln\left(\frac{1}{\sqrt{2}}\right)\) is equal to \(-\ln\left(1 - \frac{1}{\sqrt{2}}\right)\), we can simplify both sides of the equation using the properties of logarithms. Here are the steps:
Step 1: Simplify the expression on the left side:
\(\ln(\sqrt{2} + 1) - \ln\left(\frac{1}{\sqrt{2}}\right)\)
Step 2: Apply the logarithmic property \(\ln(a) - \ln(b) = \ln\left(\frac{a}{b}\right)\) to combine the logarithms:
\(\ln\left(\frac{\sqrt{2} + 1}{\frac{1}{\sqrt{2}}}\right)\)
Step 3: Simplify the expression within the logarithm:
\(\ln\left(\frac{(\sqrt{2} + 1)}{\left(\frac{1}{\sqrt{2}}\right)}\right)\)
Step 4: Simplify the denominator by multiplying by the reciprocal:
\(\ln\left(\frac{(\sqrt{2} + 1)}{\left(\frac{1}{\sqrt{2}}\right)} \cdot \sqrt{2}\right)\)
\(\ln\left(\frac{(\sqrt{2} + 1) \cdot \sqrt{2}}{\left(\frac{1}{\sqrt{2}}\right) \cdot \sqrt{2}}\right)\)
\(\ln\left(\frac{(\sqrt{2} + 1) \cdot \sqrt{2}}{1}\right)\)
Step 5: Simplify the numerator:
\(\ln\left(\frac{(\sqrt{2} + 1) \cdot \sqrt{2}}{1}\right)\)
\(\ln\left(\sqrt{2}(\sqrt{2} + 1)\right)\)
\(\ln\left(2 + \sqrt{2}\right)\)
Now, let's simplify the right side of the equation:
Step 1: Simplify the expression on the right side:
\(-\ln\left(1 - \frac{1}{\sqrt{2}}\right)\)
Step 2: Simplify the expression within the logarithm:
\(-\ln\left(\frac{\sqrt{2} - 1}{\sqrt{2}}\right)\)
Step 3: Apply the logarithmic property \(\ln\left(\frac{a}{b}\right) = -\ln\left(\frac{b}{a}\right)\) to switch the numerator and denominator:
\(-\ln\left(\frac{\sqrt{2}}{\sqrt{2} - 1}\right)\)
Step 4: Simplify the expression:
\(-\ln\left(\frac{\sqrt{2}}{\sqrt{2} - 1}\right)\)
\(-\ln\left(\frac{\sqrt{2}(\sqrt{2} + 1)}{1}\right)\)
\(-\ln\left(2 + \sqrt{2}\right)\)
As we can see, the expression \(\ln(\sqrt{2} + 1) - \ln\left(\frac{1}{\sqrt{2}}\right)\) simplifies to \(\ln(2 + \sqrt{2})\), which is equal to \(-\ln\left(1 - \frac{1}{\sqrt{2}}\right)\).

The values of the complex expressions are ✓(x - iy) = a - ib and x² + y² = (a + ib)²(a - ib)²
Calculating the complex expressionsFrom the question, we have the following parameters that can be used in our computation:
✓(x + iy) = a + ib
Changing the signs, we have
✓(x - iy) = a - ib
Multiply both expressions
This gives
✓(x + iy) * ✓(x - iy) = (a + ib)(a - ib)

As group size increases, which of the following typically occurs?
a. Complexity increases
b. Factions develop
c. The number of nonparticipating members increases
As group size increases, the complexity of the group increases (option A).
What is group size?
Even within the same species, group size can vary greatly, so we frequently need statistical tests to evaluate these measurements between two or more samples as well as statistical measures to quantify group size. Since group sizes typically follow an aggregated (right-skewed) distribution, where most groups are small, few are large, and a very small number are very large, group size measures are infamously challenging to handle statistically.
As group size increases, the complexity of managing and coordinating the group also increases.
The larger the group, the more difficult it is to communicate effectively, to make decisions, and to ensure that everyone is working towards a common goal.
This is why larger organizations often have more complex hierarchies and more formalized communication and decision-making processes.
Therefore, the correct option is A.

Calculate capital if assets are £451,100, liabilities are £20,500, income is £351,200 and expenses are £270,600.
The capital is £430,600.
Define capital.
The money that a company has on hand to support both its current operations and potential expansion is known as capital. One source of funding for it is the earnings from its operations. When calculating a company's capital worth, all of the company's physical assets and financial assets would be included (minus its liabilities).
The capital account—also referred to as the capital and financial account—records the net flow of investment transactions into an economy and is used in macroeconomics and international finance.
Solution Explained:
Given, Assets = £451,100 and liabilities = £20,500
Capital = Assets - Liabilities
