Step-by-step explanation:
If 180 kg of sugar is to be divided into 3 quantities of ratio 2:3:4 find the smallest and largest quantities.
Answers
Answer:
smallest: 40 kg, medium: 60 kg, largest quantity: 80 kg
Step-by-step explanation:
divide into 2 : 3 : 4
find the total quantities: 2 + 3 + 4 = 9 quantities.
9 quantities → 180 kg
1 quantities → \(\frac{180}{9}\) kg
1 quantities → 20 kg
Finding what the question asked for:
2 quantities → 20*2 → 40 kg
3 quantities → 20*3 → 60 kg
4 quantities → 20*4 → 80 kg
Answer:
Smallest quantity is 40 kg
Largest quantity is 80 kg
(in case you need it the middle quantity is 60 kg)
Step-by-step explanation:
In the ratio there are 9 total parts (2+3+4). If you divide the 180 kg by 9 you will get 20kg. You can now multiply the 20kg by each ratio (20×2, 20×3, and 20×4) to divide the sugar into the ratio.
20×2= 40 kg
20×3= 60 kg
20×4= 80 kg

a researcher obtained a random sample of 100 smokers and a random sample of 100 non smokers. after interviewing all 200 participants in the study, the researcher compared the rate of depression among the smokers with the rate of depression among nonsmokers
observational study
Answers
Based on the study, the researcher may develop a hypothesis that smoking is associated with an increased risk of depression.
What is Hypothesis?An explanation that is put up for a phenomena or a group of facts is called a hypothesis. It is a speculative explanation that needs more testing and improvement because it is supported only by a small body of data. A hypothesis is not a tested theory, but rather a point of departure for more research. A hypothesis is examined in scientific study by testing and observationit. The purpose of hypothesis testing is to evaluate the likelihood that the suggested explanation is accurate and to spot any discrepancies or holes in the available data. The act of testing and improving hypotheses is a crucial component of the scientific method since it ensures that scientific ideas are supported by reliable data.
How to solve?
This hypothesis can then be tested through further research, such as conducting a larger study with more participants, or conducting experiments to evaluate the potential mechanisms by which smoking may affect the development of depression.
The researcher may also use statistical methods to analyze the data collected from the study, in order to determine the significance of the relationship between smoking and depression.
If the hypothesis is supported by the evidence, the researcher may conclude that smoking is a risk factor for depression, and may recommend interventions or preventative measures to reduce the risk of depression among smokers.

Every triangle's angles MUST add up to 180. Therefore, 43 + 43 + (6-8x) must be equal to 180. So:
43 + 43 + (6 - 8x) = 180

Hey i was wondering can i move +7 from inside the absolute value in the left side to -7 outside the absolute value on the right side? for example in the question below is the answer right is the answer zero ?
Answers
Answer:
A) ZeroStep-by-step explanation:
Given equation:
|x + 7| = - 4The left side is absolute value, we know it is zero or positive value but never negative.
The right side is negative so the equation can't have solutions as we have contradiction above.
\( \rm |x + 7| = - 4\)
The statement is false for any value of x because the absolute value function is always positive or 0.
Thus, The equation has zero solutions!!~does the equation 4(2x+3)=16x+12-8x have one solution, infinitely many solutions, no solution, or two solutions.
Answers
Answer:
Infinite number of solutions
Step-by-step explanation:
Use distributive property to eliminate the parenthesis on the left:
8 x + 12 = 16 x + 12 - 8 x
combine like terms on the right:
8x+ 12 = 8 x + 12
subtract 12 from both sides
8 x = 8 x (notice both sides are identical)
subtract 8 x from both sides
0 = 0
This is a true statement that takes place for whatever x-value we use in the original equation. Therefore, the equation has infinite number of solutions (any real number "x")
Find all intersection points of the parabola y = x^2 and the circle with a radius √6 and center at (0,4).
Answers
The requried, intersection points are (√5, 5), (-√5, 5), (√2, 2), and (-√2, 2).
To find the intersection points of the parabola y = x² and the circle with radius √6 and center at (0,4), we need to solve the system of equations:
x² + (y - 4)² = 6 (equation of circle)
y = x² (equation of parabola)
We can substitute y = x² into the equation of the circle and obtain a quadratic equation in x:
x² + (x² - 4)² = 6
x⁴ - 7x² + 10 = 0
This equation can be factored as:
(x² - 5)(x² - 2) = 0
Therefore, the solutions for x are x = ±√5 and x = ±√2. To find the corresponding values of y, we can substitute these values of x into the equation of the parabola:
y = x²
For x = √5, we have y = (√5)² = 5, and for x = -√5, we have y = (-√5)² = 5.
For x = √2, we have y = (√2)² = 2, and for x = -√2, we have y = (-√2)² = 2.

Answer: 803.84cm3
Step-by-step explanation:
The formula for finding the volume of a cylinder is πr2h.
In other words, the area of the top face's circle times the height.
To find the circle's area, we first find the radius of the circle. Since the diameter is 8cm, we divide by 2 to get the radius, which is 4cm.
4cm squared is 4cm x 4cm, which is 16cm. 16cm times 3.14 is 50.24cm squared.
Now, we have the area of the circle. 50.24cm squared!
The height is 16cm, so to find the cylinder, we times the area of the circle by the height of the cylinder! So,
16cm x 50.24cm squared = 803.84cm cubed.
The volume of the can of soup is 803.84cm cubed.

in
12.3 in. Round your answer to the nearest tenth of a cubic inch.
Answers
Answer:
V = 460.68
Step-by-step explanation:
V=(lwh)/3
Volume = (1/3) * base area * height
In this case, the base of the pyramid is a square with a side length of 10.6 inches, so the base area can be calculated as:
Base area = side length * side length
Let's calculate the base area first:
Base area = 10.6 in * 10.6 in
Next, we'll substitute the values into the volume formula:
Volume = (1/3) * (10.6 in * 10.6 in) * 12.3 in
Calculating this expression will give us the volume of the pyramid. Rounding the answer to the nearest tenth of a cubic inch will provide the final result.

First things first you have to find what is in the bracket things (i don’t know what it’s called) So 3 - 7 is -4y but since it’s absolute it’s going to be 4y.
So now you’ve got 4y - 10 = -5. Your going to want to eliminate 10 so, subtract 10 to both sides giving you 4y = -5
Lastly to get y by itself you need to divide it by its self so, 4y divided by 4. Do it to both sides. This gives you…

Answers
The perimeter of the given shape in terms of pi is 22 cm + 25 pi cm.
How do you figure out perimeter?The circumference of the rectangle is equal to the sum of the lengths of its four sides. It is simple to do this because there are two of each side length; all that is needed is to sum the length and width and multiply the result by two.
By multiplying half of the semicircle's circumference by the diameter's length, one can determine the semicircle's perimeter. Thus, the semicircle's perimeter is as follows:
Perimeter of semicircle = 6 cm + (1/2) x pi x 6 cm
Perimeter of semicircle = 6 cm + 3 pi cm
Each quarter circle has a perimeter that is just one-fourth of its circumference. Consequently, the 14 cm quarter circle's perimeter is as follows:
Perimeter of quarter circle with radius 14 cm = (1/4) x 2 pi x 14 cm
Perimeter of quarter circle with radius 14 cm = 7 pi cm
And, the perimeter of the quarter circle with radius 30 cm is:
Perimeter of quarter circle with radius 30 cm = (1/4) x 2pi x 30 cm
Perimeter of quarter circle with radius 30 cm = 15 pi cm
Therefore, the total perimeter of the given shape is:
Perimeter = Perimeter of semicircle + Perimeter of quarter circle with radius 14 cm + Perimeter of quarter circle with radius 30 cm
Perimeter = (6 cm + 3 pi cm) + (7 pi cm) + (15 pi cm)
Perimeter = 22 cm + 25 pi cm.

a.How much were earnings per share?
b.Does the stock seem overpriced, underpriced, or about right given that the historical P/E ratio is 12-14?
Answers
The amount of earnings per share is $2.77.
Earnings per sharea. Earnings per share = price per share / (P/E) ratio
Earnings per share = $46.07 / 16.66
Earnings per share= $2.77
B. Overpriced or underpriced stock
At P/E ratio = 12
Earnings per share = $46.07 / 12
Earnings per share = $3.84
Earning yield = ( Earning per share / market value )× 100
Earning yield = (3.84 / $46.07 ) × 100
Earning yield = 8.34%
At P/E ratio = 13
Earnings per share = $46.07 / 13
Earnings per share = $3.54
Earning Yield= (3.54 / 46.07 ) × 100
Earning Yield= 7.68%
At P/E ratio = 14
Earnings per share = $46.07 / 14
Earnings per share = $ 3.3
Earnings yield= ( 3.3 / 46.07 )×100
Earnings yield= 7.16%
Average of earning yield given P/E ratio is 12-14
Average of earning yield= ( 8.34 + 7.68 + 7.16 ) / 3
Average of earning yield= 7.73%
Earning yield = ( Earning per share / market value ) × 100
Earning yield= ( 2.77 / 46.07 ) ×100
Earning yield = 6.01%
Hence, Based on the above the stock is underpriced.
