What is the answer ?

Step-by-step explanation:

I know that both sides of the cats, males and females, receive the same # of new cats.

I write an equation, (not an inequality though):

3((34+2x)/5)=2((13+2x)/5)

From here on, I solve for x. I get x = -38. I know we can't have negative pairs and we're only bringing in more cats, and not taking any away. I add 38, and try to see what percentage of cats are male, and I get fairly close, getting to about 62.5% I think. Then, I divide 38 by 2, getting 19, and see what else I can get. I try to find a value between the 38 and lesser 19 so as to find a value which will give me a male cat percentage of 60%. I get about 57.5% with 19 plugged in, which is when I see that hey, the differences are the same. What I then do is find the average of 19 + 38, which is 57.5. I round that to 58, and I get the right answer.

I see that perhaps my solution wasn't really orthodox or anything, but with a little bit of trial and error and a bit of my creative thinking, I guess I managed to solve the problem. What worries me though is this is the first problem in the "questions" section of the inequalities section of AoPS, so I'm definitely struggling to deal with the concepts.

Answer: abrimos

Step-by-step explanation: That's what it is on my quiz.

In the sentence "Nosotros _____ la ventana", the correct verb form is "abrimos". The best answer is option D.

The verb "abrir" is a Spanish verb that means "to open", and the first person plural form of this verb is "abrimos". So the sentence "Nosotros abrimos la ventana" translates to "We open the window".

The other verb forms in the options ("compartimos", "abro", and "escribimos") do not fit the context of opening the window. "Compartimos" means "we share", "abro" means "I open" (first person singular), and "escribimos" means "we write". So these forms are not the correct form to complete the sentence.

Answer:

40.5=40 1/2

Step-by-step explanation:

Answer: 40.5 as a fraction is 81/2. ✅

Step-by-step explanation:

Sure, here's a step-by-step explanation of how I got the fraction 81/2 for the decimal number 40.5:

Identify the number of decimal places in the decimal representation of 40.5, in this case, it's 1.

Write the decimal number as a fraction by placing the decimal number over a power of 10 that has the same number of zeroes as there are decimal places in the decimal representation. In this case, it's 40.5 / 10^1 (or 40.5/10).

Simplify the fraction if possible by dividing both the numerator and denominator by a common factor if one exists. In this case, the fraction is already in its simplest form.

The fraction representation of 40.5 is 405/10

Simplify the fraction again if possible by dividing both the numerator and denominator by a common factor if one exists. In this case, the fraction can be simplified further by dividing both the numerator and denominator by 5.

So, the fraction representation of 40.5 is 81/2

Hence, the fraction representation of 40.5 is 81/2.

We can conclude that (π) represents a irrational & transcendental number.

An irrational number is a number that cannot be expressed as a fraction p/q for any integers {p} and {q}.

Step-by-step explanation:

The amount of Cashew nuts is 0.205

The amoun of Peanuts is 0.295

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Amount of Cashew nuts = x

Amoun of Peanuts = y

Now,

We can make two equations.

x + y = 1/2 ____(1)

x = 1/2 - y  _____(20

Substituting (2) in (3)

6.25x + 2.10y = 1.90 _____(3)

6.25 (1/2 - y) + 2.10y = 1.90

3.125 - 6.25y + 2.10y = 1.90

3.125 - 4.15y = 1.90

3.125 - 1.90 = 4.15y

y = 1.225/4.15

y = 0.295

And,

x = 1/2 - y

x = 1/2 - 0.295

x = 0.205

Thus,

Amount of Cashew nuts = 0.205

Amoun of Peanuts = 0.295

Answer:

The graph of g(x) = 3x−5 is obtained from the graph of g(x) = 3x by applying the transformation (f(x) = f(x) + b) where b = -5. This transformation is a vertical shift of the graph of g(x) = 3x downward by 5 units.

The graph of g(x) = 3x is a line with a slope of 3 and y-intercept of 0. By subtracting 5 from each y-coordinate, the y-intercept of the graph is shifted downward by 5 units, resulting in a y-intercept of -5. The slope of the graph remains the same as the original function, 3. So the graph of g(x)=3x−5 is the same line as g(x)=3x, but shifted downward 5 units.

Note that the area of Triangle CDE will be 4 square units.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.

The area of a ΔCDE is derived as follows:

Given that:

C = (4,1)

D = (4, -5) and

E = (2, -3)

A = 1/2 [x1 (y2 - y3_ + x2(y3-y1) + x3 (y1-y2)]

Inputting the given values, we have:

A = 1/2 [ 4(-5+3) + 4(-3+1) + 2(-1+5)]

A = 1/2 [4(-2) + 4 (-2) + 2(4) ]

A = 1/2 [-8-8+8]

A = 1/2(-8)

A = -4

The angular speed of the fan  138π radians/minute or 433.54  radians/minute.

The linear speed of the tip of a blade is 8237.26 inches/minute

a) The angular speed of a fan is the number of revolutions per minute (RPM) multiplied by 2π radians per revolution.

So the angular speed of the fan in radians per minute is:

69 RPM × 2π radians/revolution = 138π radians/minute

b) The linear speed of the tip of a blade is found by multiplying the angular speed in radians per minute by the radius of the fan.

Any function that depicts a straight line on the coordinate plane is said to be linear. For instance, the equation y = 3x – 2 indicates a straight line on a coordinate plane, indicating that it is a linear function.

A non-function inverse would be a mathematical operation that does not produce a new function. Examples of non-function inverses include division, subtraction, and multiplication. These operations can be used to undo the effects of an original function, but they do not create a new function. Division can be used to “undo” multiplication, for example. However, the end result is not a new function, but rather a number or set of numbers.
