Three families, a, b, & c share 480 kg of rice. B receives twice as much as a, c receives half of b. How much rice does each family get?
Answer:
Family a got 120kg, b got 240 kg and c got 120 kg
Step-by-step explanation:
Given that 480kg of rice is shared by families a, b, c. let these alphabets represent the amount received by each family.
a + b + c = 480
Given that B receives twice as much as a, c receives half of b then,
b = 2a and
c = 1/2 b = b/2
from b = 2a,
a = b/2
substituting into the first equation
b/2 + b + b/2 = 480
b + b = 480
2b = 480
b = 480/2
= 240 kg
a = c = b/2
hence a = c = 240/2 = 120kg

What value of p will make the expression below a perfect square? x^2 - x + P
Answer:
p = \(\frac{1}{4}\)
Step-by-step explanation:
To make a perfect square
add ( half the coefficient of the x- term )² to x² - x, that is
x² + 2(- \(\frac{1}{2}\) )x + \(\frac{1}{4}\) with p = \(\frac{1}{4}\) , thus
x² - x = (x - \(\frac{1}{2}\) )² + \(\frac{1}4}\)
Answer:

(3ab - 6a)^2 is the same as
2(3ab - 6a)
True or false?
False. The expression \((3ab - 6a)^2\) is not the same as 2(3ab - 6a).
The expression\((3ab - 6a)^2\) is not the same as 2(3ab - 6a).
To simplify \((3ab - 6a)^2\), we need to apply the exponent of 2 to the entire expression. This means we have to multiply the expression by itself.
\((3ab - 6a)^2 = (3ab - 6a)(3ab - 6a)\)
Using the distributive property, we can expand this expression:
\((3ab - 6a)(3ab - 6a) = 9a^2b^2 - 18ab^2a + 18a^2b - 36a^2\)
Simplifying further, we can combine like terms:
\(9a^2b^2 - 18ab^2a + 18a^2b - 36a^2 = 9a^2b^2 - 18ab(a - 2b) + 18a^2b - 36a^2\)
The correct simplified form of \((3ab - 6a)^2 is 9a^2b^2 - 18ab(a - 2b) + 18a^2b - 36a^2\).
The statement that\((3ab - 6a)^2\) is the same as 2(3ab - 6a) is false.

A rancher has 3000 feet of fencing with which to construct adjacent, equally sized rectangular pens as shown in the figure above. What dimensions should these pens have to maximize the enclosed area?
The required dimensions of a rectangular rancher with perimeter for fencing, 3000 feet are equal the 500 feet and 375 feet at maximum area of 3,75,000 ft².
We have a rancher which to construct adjacent, equally sized rectangular pens with the fencing of 3000 feet. Suppose that the rancher need to be fenced in the way shown in the attached figure. Then, the perimeter is 4x + 3y = 3000
=> x \( =\frac{3000 - 3y}{4} \).
The area of rectangle is represented by A=L × W --(1) , where L and W are dimensions of rectangles. The total area will be A = 2× x × y --(2)
=> A = 2× (\(\frac{3000 - 3y}{4}\))× y
= ( \( 1500 - \frac{3y}{2} \))y
= \( 1500y - \frac{3y²}{2} \)
Now, differentiate above area function, with respect to y, and equate to 0, for determining the critical points on the graph, \(\frac{dA}{dy} \) = A'(y) =\( 1500 - \frac{6y}{2} \) = 0
=> y = \(\frac{1500}{3} = 500 \)
Also, x \( =\frac{3000 - 3× 500}{4} \).
\( =\frac{1500}{4} = 375 \).
Maximum area = 375 × 500 × 2 = 375000 ft². Hence, the dimensions that will give the maximum area are 500 feet and 375 feet.

pool has a perimeter of
150 meters. The length of
the pool is twice the width
of the pool. What is the
length of the pool?
Answer:
77
Step-by-step explanation:
perimeter=150
lets name the length x
length=x
width=x-2
2[x±x-2]=150
2x±2x-4=150
4x=154
154÷4=77
x=77
The length of the pool is 50 meters and this can be determined by using the formula of the perimeter.
Given :
A rectangular swimming pool has a perimeter of 150 meters. The length of the pool is twice the width of the pool.The following steps can be used in order to determine the length of the pool:
Step 1 - The formula of the perimeter of the rectangle is given by:
P = 2(l + w)
where l is the length of the rectangle and w is the width of the rectangle.
Step 2 - According to the given data, the length of the pool is twice the width of the pool that is:
l = 2w --- (1)
Step 3 - Now, substitute the known terms in the formula of the perimeter.

YOU WILL NOT GET THE ANSWER RIGHT. Express your answer as decimal, rounded to the nearest thousandth (three decimal places) in mi/hr - no spaces EXAMPLE: 78.345mi/hr
The dog's running speed of 5 km/hr can be converted to approximately 3.125 mi/hr by multiplying it by the conversion factor of 1 mi/1.6 km. Rounding to the nearest thousandth, the dog can run at about 3.125 mi/hr.
To convert the dog's running speed from kilometers per hour (km/hr) to miles per hour (mi/hr), we need to use the conversion factor of 1.6 km = 1 mi.First, we can convert the dog's speed from km/hr to mi/hr by multiplying it by the conversion factor: 5 km/hr * (1 mi/1.6 km) = 3.125 mi/hr.
However, we need to round the answer to the nearest thousandth (three decimal places). Since the digit after the thousandth place is 5, we round up the thousandth place to obtain the final answer.
Therefore, the dog can run at approximately 3.125 mi/hr.

find the marked angle of
Answer:
∠ C = 100°
Step-by-step explanation:
since 2 sides of the triangle are congruent then the triangle is isosceles with base angles congruent.
consider the angle inside the triangle to the left of 140°
this angle and 140° are a linear pair and sum to 180°
angle + 140° = 180° ( subtract 140° from both sides )
angle = 40°
then the angle on the left of the triangle = 40° ( base angles congruent )
the sum of the angles in a triangle = 180° , so
∠ C + 40° + 40° = 180°
∠ C + 80° = 180° ( subtract 80° from both sides )
∠ C = 100°

asuming 14 people, 5 men and 9 women, how many ways can they sit in a circle such that every man is diametricaly opposite a woman
There are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.
In this problem, we want to find the number of ways to seat 14 people in a circle such that every man is diametrically opposite a woman.
Since every man must be diametrically opposite a woman, we can pair each man with one woman. There are 5 men and 9 women, so there are 5 pairs. We need to find the number of ways to seat these 5 pairs of people in a circle.
To do this, we can first seat one pair in any position. Then, we can seat the second pair anywhere but opposite the first pair. This gives us 11 positions for the second pair. Continuing in this way, we see that there are 11 * 6 * 5 * 4 * 3 = 7920 ways to seat the 5 pairs of people in a circle.
So, there are 7920 ways to seat 14 people in a circle such that every man is diametrically opposite a woman.

Answer:A
Step-by-step explanation:
use the function f(x)= 2x^3 -5x 7 to find the following values: of x= -4
To find the value of the function f(x) = \(2x^3 - 5x + 7\) at x = -4, we substitute -4 into the function and simplify. The value of the function at
x = -4 is -101.
To calculate the value of the function \(f(x) = 2x^3 - 5x + 7\)at x = -4, we substitute -4 for x in the equation:
\(f(-4) = 2(-4)^3 - 5(-4) + 7\)
Simplifying the expression, we have:
f(-4) = 2(-64) + 20 + 7
f(-4) = -128 + 20 + 7
f(-4) = -101
Therefore, when x = -4, the value of the function \(f(x) = 2x^3 - 5x + 7\)is -101. This means that if we substitute -4 into the function, we get a result of -101.

It will take the town 21 years 4 months to reach 4600 in population
What is rate?
a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.
initial population = 3000
population increase every year = 2.5% of 3000
which is 2.5/100 x 3000 = 75
let the time taken to reach 4600 be d
increment for d number of years = 75d
Total population after d years is 75d + 3000
so 75d + 3000 = 4600
75d = 4600 - 3000
75d = 1600
d = 1600/75

Answer: Option (B)
Explanation: every problem resolution or solution starts with identifying the problem and its consequences or effects. After that, solutions are found to eliminate the problem, and two or more alternative solutions are made. After that, evaluate and select the best solution to solve the problem more easily. If the solution fills all the required conditions and effective problem resolution occurs, implement the solution.
Other options are wrong because of the following reasons.
A. This option starts the process of identifying the best solution, but understanding the nature of the problem or possible solutions can occur.
C. Evaluation and selection of the best solution are only taken after understanding the problem and checking other solutions.
D. The evaluation and selection of the best solution are required before implementing the solution to get an effective solution that can fulfill all of the conditions.
B. Your initial explanation is mostly accurate, but these additional details provide a clearer understanding of the problem-solving process.
A. The process you described is commonly known as problem-solving or decision-making. Here's a breakdown of the steps involved: Identify the problem, Generate alternative solutions, Evaluate alternatives, Select the best solution, Implement the solution.
Identify the problem: The first step is to clearly identify and define the problem at hand. This involves understanding the nature of the problem, its causes, and its consequences or effects. Without a clear understanding of the problem, it would be difficult to find an appropriate solution.
Generate alternative solutions: Once the problem is identified, the next step is to brainstorm and generate multiple possible solutions or approaches to address the problem. This step encourages creativity and exploration of different options.
Evaluate alternatives: After generating alternative solutions, each option should be evaluated carefully. Factors such as feasibility, cost, time, resources required, and potential risks or benefits should be considered. This evaluation helps in narrowing down the options to those that are most viable.
Select the best solution: Based on the evaluation, one or more solutions may stand out as being the most effective or suitable for solving the problem. The best solution is selected based on its ability to address the problem efficiently and meet the desired objectives.
Implement the solution: Once the best solution is chosen, it is put into action. Implementation may involve planning, executing tasks, allocating resources, and managing the necessary steps to bring the solution to fruition.
It's important to note that the order of the steps may vary depending on the context and the complexity of the problem. While it's generally logical to evaluate and select the best solution before implementing it, sometimes it may be necessary to iterate through the steps, re-evaluate options, or make adjustments during the implementation phase.
Regarding the other options you mentioned:
A. This option suggests starting with identifying the best solution without understanding the nature of the problem or considering other possible solutions. As you correctly pointed out, this approach is flawed because it skips important steps in the problem-solving process.
C. This option implies evaluating and selecting the best solution before understanding the problem or considering other alternatives. Again, this is incorrect because a thorough understanding of the problem and exploration of multiple solutions should precede the evaluation and selection stage.
D. This option suggests implementing the solution before evaluating and selecting the best one. However, it's generally more effective to assess the potential effectiveness of different solutions before committing to their implementation.
In summary, your initial explanation is mostly accurate, but these additional details provide a clearer understanding of the problem-solving process.
