The Weight on Venus is 3.64 pounds
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
They need to find out how much a rock that weights 4 pounds on earth would weight on Venus.
So, the Weight on Venus
= 4 x 0.91
= 4x 0.9+ 4 x 0.01
= 3.6+ 0.04
= 3.64
Hence, the Weight on Venus is 3.64 pounds

Evaluate the expression.
12(43−6⋅32)
Answer:
the answer is 5.
Step-by-step explanation:
The expression 12(43−6⋅32) evaluates to -132 by following the order of operations, first calculating the exponent, then the multiplication and subtraction inside the parentheses, and finally multiplying the result by 12.
To evaluate the given expression 12(43−6⋅32), we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
First, solve the exponent 32 which is 9.
Then, perform the multiplication within the parentheses: 6⋅9 equals 54.
Now, subtract that result from 43: 43 - 54 which gives us -11.
Finally, multiply the result by 12: 12 ⋅ (-11) equals -132.
Therefore, the expression 12(43−6⋅32) evaluates to -132.

A. Kendra should have multiplied by 4 in both the numerator and the denominator.
B. Kendra should have divided by 2 instead of multiplying by 2 in the denominator.
C. Kendra should have added 40 and 20.
D. Kendra should have the part to whole equation written as 100/40 (100 over 40)
Answer:
B. Kendra should have divided by 2 instead of multiplying by 2 in the denominator.
Step-by-step explanation:
In Kendra’s class, 40 percent of the students earned an A on the math test.
Let the total students in the class be = x
So, as per the situation given, we can say that
[tex]0.40\times x=20[/tex]
x = 50
Hence, there are 50 students in the class.
We can cross check this as:
[tex]0.4\times50=20[/tex]
So, Kendra surely did a mistake.
Kendra should have divided 100 by 2. But she multiplied by 2.
Chelsea uses 3 pounds of apples to make 4 cups. How many pounds of apple does she need to make 6 pints of applesauce
Here, we know that 1 pint = 2 cups
Thus, 1 cup = [tex] \frac{1 pints}{2} [/tex]
3 ponds apples are needed for 4 cups i.e. 3 ponds of apples = 4 cups of applesauce
1 cup of applesauce = [tex] \frac{3 ponds}{4} [/tex]
Now, 6 pints will have 12 cups of applesauce
Multiplying this equation by 12 ⇒ 1 cup of applesauce = [tex] \frac{3 ponds}{4} [/tex]
12 ×1 cup of applesauce = 12 × [tex] \frac{3 ponds}{4} [/tex]
So, 12 cups of applesauce = 9 ponds of apple.
Thus, 9 ponds of apple will be needed to make 6 pints of applesauce.

A family has 8 girls and 4 boys. A total of 3 children must be chosen to speak on behalf of the family at a local benefit. What is the probability that no girls and 3 boys will be chosen?
Final answer:
The probability that no girls and 3 boys will be chosen is 1/55 or approximately 1.82%.
Explanation:
To find the probability that no girls and 3 boys will be chosen, we need to determine the total number of possible outcomes and the number of favorable outcomes.
There are a total of 12 children (8 girls + 4 boys) in the family. Since 3 children are being chosen, the total number of possible outcomes is the combination of 12 children taken 3 at a time, which is denoted as C(12, 3) = 220.
The number of favorable outcomes is choosing 3 boys from the 4 available boys, which is denoted as C(4, 3) = 4.
Therefore, the probability of choosing no girls and 3 boys is 4/220 = 1/55, which can be reduced to approximately 0.0182 or 1.82%.

in an experiment cause and effect is analyzed, and in an observational study, it is not
in an experiment one group is studied over a short period of time, and in an observational study, the group is studied over a longer period of time
Answer: In an observational study, researchers do not control treatment, and in an experiment they do .
Step-by-step explanation:
Observational study is the study where the researcher observes the subjects and measures variables, but does not influence the population where as in an experiment the experimenter has control on the independent variable to see the effect on the dependent variable.
So the correct difference between an observational study and an experiment is that "in an observational study, researchers do not control treatment, and in an experiment they do."
Answer:
B on EDG
Step-by-step explanation:
A jar contains blue, red, yellow, and green marbles.P(blue) = 1/4. What type of probability is illustrated and why?
The probability stated as P(blue) = 1/4 illustrates theoretical probability, which is determined by the number of favorable outcomes divided by the total number of outcomes without the need for any experiment or past data.
The type of probability illustrated by the statement "A jar contains blue, red, yellow, and green marbles with P(blue) = 1/4" is theoretical probability. This is because the probability value is based on the known possible outcomes and the assumption that each outcome has an equal chance of occurring. For example, if a bag contains four green marbles, three red marbles, and two yellow marbles, the theoretical probability of drawing a yellow marble followed by a green marble without replacement would be calculated using the number of ways these events can happen divided by the total number of outcomes.
Theoretical probability does not require experimental results or past data and is often used in problems involving equally likely events, such as drawing marbles from a jar or flipping a fair coin. In contrast, experimental probability is based on the frequency of an event happening from trials or experiments. In the given example with the jar of marbles, we assume that each marble color is equally likely to be drawn.
Avenue A is perpendicular to North Street. What is the relationship between Avenue A and South Street?
Final answer:
Avenue A is perpendicular to North Street, and it would also be perpendicular to South Street since they run parallel. The concept of vector components Ax and Ay, being perpendicular and analogous to these streets, helps illustrate the perpendicular relationship between Avenue A and South Street.
Explanation:
Given that Avenue A is perpendicular to North Street, we can infer that Avenue A is also perpendicular to South Street because in a typical city grid, north and south streets run parallel to each other. When two lines are perpendicular to a third line, they are parallel to each other and form a 90° angle with the perpendicular line.
The relationships among vectors can help further illustrate this idea. If we look at the components of a vector, Ax and Ay, where Ax is the movement in the east-west direction (like Avenue A) and Ay is the movement in the north-south direction (like North Street), they form a right angle with each other. If you walk along Avenue A (the Ax component), then along North Street (the Ay component), you construct a path that is the resultant vector A with its own magnitude and direction.
The sum of these vectors is represented as Ax + Ay = A. This combination holds only for vector quantities, which include both magnitude and direction. This principle does not apply when we're summing up the magnitudes alone, as in the example where if Ax is 3 m east and Ay is 4 m north, the direct path A would not simply be their sum in magnitudes but would instead be a diagonal 5 m northeast according to the Pythagorean theorem.

What do you do if there are no matching coefficients
When dealing with null coefficient terms in mathematics or chemistry, they can be a tool to simplify calculations. Replacing zero coefficients with a positive approximation or selecting rows with zeroes in matrices can ease the process. Always verify solutions by substituting them back into the original equations to ensure correctness.
When you encounter situations where there are no matching coefficients in your algebraic equations, it is important to look for null coefficient terms. Such terms can help simplify the computations. For instance, if you are working on balancing chemical equations or solving systems of equations, and one of the coefficients is zero, this can be advantageous because multiplying by zero is a straight-forward operation.
If a coefficient equals zero, like one in a characteristic equation, replace it with a positive quantity approaching zero from the right-hand side. Continue with the analysis after this adjustment. Additionally, when working with matrices, selecting a row with zeros as the coefficient row can simplify the process of expansion by minors since some minors will not need to be computed and can just be multiplied by the zero coefficient.
In the case of balancing equations in chemistry or optimizing coefficients in a mathematical model, practice and a methodical approach are necessary. Make sure to double-check your computations and if you are unsure about the correctness of your solution, substitute it back into the original equation.
What is 5√ ?
Place a dot on the number line at the best approximation.
The required √5 on the number line is shown in the image attached.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here
To locate √5 on a number line, we can begin by locating the integers that √5 lies between. We know that 2² = 4 and 3² = 9, so √5 must be between 2 and 3.
To get a more accurate estimate, we can divide the distance between 2 and 3 into 10 equal parts (tenths). Each tenth represents 0.1 units on the number line. We know that 0.5 is halfway between 0 and 1, so √5 must be a little more than halfway between 2 and 3.
By estimating the position of √5 on the number line, we can approximate it as being around 2.2 to 2.3.
Thus, the required √5 is shown in the image attached.

you want to determine if two triangle are similar. what is the minimum number of angles you need to measure to determine if the triangles are similar
To know if 2 triangles are similar, we would need at least 2 angles, why?
Since a triangle has 3 angles, and those angles add up to 180°, we can easily determine the third angle.
Example: If 2 angles of a triangle were 13 and 97, we would know that 13 + 97 = 110, then 180° - 110° = 70°, so the missing angle is worth 70°.
