Can you construct a triangle using line segments 12 cm 7 cm and 5 cm?

Answer: Apples $0.18 (18 Cents) Bananas $0.14 (14 cents)

Step-by-step explanation:

Math knowledge would give the cost for each item. We have:

4 apples + 6 bananas = $1.56

and

9 apples + 7 bananas = $2.60

To find a cost, we encode an apple as 'a', and a banana as 'b' in the following two main equations:

4a+6b=1.56

9a+7b=2.6

The following formula represents the situation by using elimination method to find, let's say, the banana value:

4a+6b=1.56 , 9a+7b=2.6

9×4a+9×6b=9×1.56, 4×9a+4×7b=4×2.6

36a+54b=14.04, 36a+28b=10.4

36a−36a+54b−28b=14.04−10.4

54b−28b=14.04−10.4

26b=14.04−10.4

26b=3.64

b=3.64÷26

b=0.14

That is a banana costs $0.14 (14¢).

Now we have found the value of a banana, we substitute this new value in one of the main equations above to reduce variables so that we can find the value of an apple as follows:

4a+6b=1.56

4a+(6×0.14)=1.56

4a+0.84=1.56

4a=1.56-0.84

4a=0.72

a=0.72÷4

a=0.18

Simply enough, an apple costs $0.18 (18¢), and a banana costs $0.14 (14¢).

Answer: 3ml:4ml:7ml

Step-by-step explanation: To simplify ratios you have to find the highest number that you can divide all the parts in the ratio by (AKA as highest common factor)

In this case the common factor of 18,24 and 42 is 6.

so now divide all the parts by 6:

18/6=3

24/6=4

42/6=7

finally put these numbers back into the correct ratio format and for this question put on the units.

final answer= 3ml:4ml:7ml

An explicit formula for aₙ, the nth term of the arithmetic sequence is aₙ = 3 + 5(n - 1)..

Mathematically, the nth term of an arithmetic sequence can be calculated by using this mathematical expression:

aₙ = a₁ + (n - 1)d

Where:

From the information provided, we have the following parameters:

First term, a₁ = 3

Second term, a₂ = 8

Next, we would determine the common difference as follows:

Common difference, d = a₂ - a₁

Common difference, d = 8 - 3

Common difference, d = 5

Substituting the parameters into the mathematical expression, we have;

aₙ = 3 + (n - 1)(5)

aₙ = 3 + 5(n - 1).

Observational data that contains a numerical value or amount is called Quantitative observation.

What is observational data?

An observational study draws conclusions from a sample to a population in disciplines like epidemiology, social sciences, psychology, and statistics when the independent variable is not under the researcher's control due to ethical considerations or logistical limitations.

Observational data in market research refers to information gathered without the research subject (such as a specific client, patient, employee, etc.) having to be explicitly involved in documenting what they are doing.

An objective collection of data, quantitative observation refers to "associated to, of or depicted in terms of a quantity" and is primarily focused on numbers and values.

Methods of statistical and numerical analysis are used to derive the results of quantitative observation.

Hence, observational data that contains a numerical value or amount is called Quantitative observation.

The radius of the circle, in inches, is (2√6)/π.

The perimeter of an equilateral triangle is equal to 3 times its side length. We know that the area of a circle is equal to πr2, where r is the radius of the circle. Therefore, the radius of the circle, in inches, is equal to the square root of (3*s2)/π, where s is the length of the side of the triangle.

For example, if the length of the side of the triangle is 8 inches, then the radius of the circle is equal to the square root of [(3*82)/π] = (24/π) inches. Simplifying this into simplest radical form, we get (2√6)/π inches. Thus, the radius of the circle, in inches, is (2√6)/π.

The element X will take 7.3 minutes to decay to 26 grams.

Radioactive radiations are the radiations that an atom nucleus releases.

It is a sequence of numbers that have common differences.

The decaying acts like an arithmetic progression in which a=670,d=-30.45 (per minute decaying), and n we have to find with the value of 26 grams.

So, the formula of the nth term of an arithmetic progression is

nth term=a+(n-1)d

26=220+(n-1) x (-30.45)

-194=-30.45n+30.45

-224.45 =-30.45n

n=7.3 (after rounding off)

Hence the element X would take 22.10 minutes to decay to 26 grams.

Answer:

Step-by-step explanation:

Brad's solution to find the surface area of the composite figure is not correct.

In his solution, Brad adds the surface areas of the triangular prism and the rectangular prism separately,

but it's not taking into account that the two prisms share a face that is 14 by 20.

When finding the surface area of a composite figure, it's important to take into account any shared faces.

Since the two prisms share a face that is 14 by 20, Brad should subtract this area from one of the prisms,

otherwise he will be counting it twice in the final result.

The correct method would be:

Rectangular prism: (2 * 8 * 14) + (2 * 14 * 20) + (2 * 8 * 20) = 1,104 cm^2

Triangular prism: (1/2 * 14 * 12) + (1/2 * 13 * 15) + (3 * 14 * 20) = 1,008 cm^2

Subtracting shared area: 1,104 cm^2 + 1,008 cm^2 - (14 * 20) = 2,096 cm^2.

So Brad's solution is incorrect, the correct surface area of the composite figure is 2,096 cm^2.

Yes, the conditions for constructing a 90% confidence interval for the difference in the true mean growth of all large- and small-cap stocks for the last 60 days are met.

Shares of businesses having a market value between $300 million and $2 billion are considered small-cap stocks. Small-cap firms have the potential for rapid development, which makes them attractive investment targets even if their stocks may be more volatile and carry greater risks for buyers.

Large-cap stocks, commonly referred to as large caps, are stocks that are traded for businesses with a market value of at least $10 billion. Because investors gravitate toward quality and stability and become more risk-averse during challenging markets, large-cap companies often exhibit lower volatility.

Thus, the conditions for constructing a 90% confidence interval for the difference in the true mean growth of all large- and small-cap stocks for the last 60 days are met.

The possible outcomes for rolling two six-sided number cubes are the integers from 2 to 12. In order for Asher to have a better probability of winning than Eitan, Asher's winning outcome must be a lower number than Eitan's winning outcome of 11. The possible winning outcomes for Asher are therefore 2, 3, 4, 5, 6, 7, 8, 9, 10. So the possible outcomes that Asher needs to win the game are 2, 3, 4, 5, 6, 7, 8, 9, 10.

As per the unitary method, the number of matches produced in Oregon over the same period is 64

The term unitary method is known as the method of finding the value of a single unit from the value of multiple units

Here we have given that the increase in the number of matches produced in California from 1980 to 1990 exceeds.

Therefore, the number of increase is calculated as,

CA = 0.33(1.2) = 396

If the increase is calculated as,

=> 0.33(1.6) = 528

Then the difference is calculated as,

=> 528 - 396 = 132

Similarly the number of matches in Oregon is calculated as.

=>  0.17(1.2) =204 M

=> 0.17(1.6) = 272 M

Therefore, the difference is calculated as

=> 272 -204 = 68

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the difference of length be represented as A

Now , the equation will be

The length of Ellen's pencil is p = 2x + 1/5 cm

The length of Tom's pencil is q = 5x + 2/5 cm

Now , the difference of length A = q - p

Substituting the values in the equation , we get

The difference of length A = 5x + 2/5 cm - 2x + 1/5 cm

On simplifying the equation , we get

The difference of length A = ( 5x - 2x ) + ( 2/5 - 1/5 ) cm
