I have been wondering this question for quite some time. What is 87 - 45x /3

To determine how long it will take Janet and Gerry to finish the job together, we need to calculate their combined work rate.

Let's first find the individual work rates:

Janet's work rate: 1 job / 3 hours = 1/3 job per hour

Gerry's work rate: 1 job / 2 hours = 1/2 job per hour

If Janet works alone for 1 hour, she completes 1/3 of the job.

When they work together, their combined work rate is the sum of their individual work rates:

Combined work rate = Janet's work rate + Gerry's work rate

= 1/3 job per hour + 1/2 job per hour

= 2/6 job per hour + 3/6 job per hour

= 5/6 job per hour

Now, since Janet has already completed 1/3 of the job, the remaining fraction of the job to be completed is 1 - 1/3 = 2/3.

To find the time it takes for Janet and Gerry to finish the remaining 2/3 of the job together, we can use the formula:

Time = Amount of work / Combined work rate

Time = (2/3 job) / (5/6 job per hour)

Simplifying, we get:

Time = (2/3) / (5/6) Time = (2/3) * (6/5) Time = 4/5 hour

Therefore, it will take Janet and Gerry approximately 4/5 hour (or 48 minutes) to finish the remaining 2/3 of the job together.

Given that,
To determine the estimation of 11 4/5 divided by 3 1/5.

In mathematics, it deals with numbers of operations according to the statements.

In the given question we have given, 2 mixed fractions we have to determine the simplified fraction by dividing one from the other, as stated in the question.

Simplification,

11 + 4 / 5 = 59 / 4
3 + 1 / 5 = 16 / 5

Step-by-step explanation:

The Solow model can be applied to a programmer's skill by considering human capital as the equivalent of physical capital, with accumulation, depreciation, and technological progress affecting skill development.

The Solow model is a macroeconomic model that explains long-term economic growth. It is typically applied to analyze the growth of physical capital, such as machinery and equipment. However, in this case, we can adapt the Solow model to represent a computer programmer's skill at writing code.

In the context of a computer programmer's skill, we can consider human capital as the equivalent of physical capital in the traditional Solow model. Human capital refers to the knowledge, skills, and abilities that individuals possess and can contribute to the production process. To apply the Solow model to a programmer's skill, we can use the following components:

Inputs: In the Solow model, the main input is physical capital. In this adaptation, the input would be the programmer's human capital, which includes their existing knowledge and skills in coding.

Accumulation: The model assumes that physical capital accumulates over time through investment. Similarly, a programmer's human capital can accumulate through learning new coding languages, acquiring new skills, and gaining experience.

Depreciation: In the Solow model, physical capital depreciates over time due to wear and tear. Similarly, a programmer's human capital can depreciate if they don't actively use certain programming languages or if their skills become outdated.

Technological progress: The Solow model accounts for technological progress as a factor that increases productivity. In the case of a programmer, technological progress would involve advancements in coding languages, frameworks, tools, and methodologies that enhance their productivity and efficiency.

The external angle theorem states that the measure of the external angle of a triangle is equal to the sum of the two opposite internal angles.

In this case

Then

∠4 is greater than ∠2 and ∠1, so A and B check

And F also checks

We know that the sum of the internal angles of a triangle add up to 180º so that:

And we also know that ∠3 and ∠4 are a linear pair, this means that they also add up to 180º:

Since both expressions are equal to 180º we can conclude that they are equal:

Subtract ∠3 from both sides of the equation and we get that

As stated by the external angle theore, the measure of the external angle, ∠4, of a triangle is equal to the sum of the opposite interior angles, ∠1+∠2 → With this, is proven that F is correct

If angles 1 and 2 add up to angle 4, then, by logic, their measure has to be less than angle 4

→ and this is how you know that ∠1 and ∠2 are less than ∠4

If the best fit line is nearly horizontal, it suggests no significant relationship between height and head circumference.

In this scenario, the explanatory variable is the child's height, as it is being used to predict the head circumference.

The response variable is the head circumference itself, as it is the variable being predicted or explained by the height.

To draw a scatter diagram of the data, you would plot the child's height on the x-axis and the corresponding head circumference on the y-axis. Each data point would represent a child's measurement pair.

Once all the data points are plotted, you can then draw the best fit line, also known as the regression line, that represents the overall trend or relationship between height and head circumference.

By observing the scatter diagram and the best fit line, you can determine the relationship between a child's height and head circumference.

If the best fit line has a positive slope, it indicates a positive relationship, meaning that as height increases, head circumference tends to increase as well.

If the best fit line has a negative slope, it indicates a negative relationship, meaning that as height increases, head circumference tends to decrease.

By assessing the slope of the best fit line in the scatter diagram, you can determine whether the relationship between height and head circumference is positive, negative, or nonexistent.

Step-by-step explanation:

The length of the shortest leg of T is approximately 18.33 units. We are given that the length of the altitude drawn to the hypotenuse (h) is 8, and the length of the hypotenuse (c) is 20.

We can start by using the area formula for a triangle:

Area = 1/2 * base * height

In this case, the base is the length of the hypotenuse (c), and the height is the length of the altitude (h). So we have:

Area = 1/2 * c * h

Substituting the given values, we get:

Area = 1/2 * 20 * 8 = 80

We also know that T is a right triangle, so we can use the Pythagorean theorem:

a^2 + b^2 = c^2

Substituting the given values, we get:

a^2 + b^2 = 20^2

a^2 + b^2 = 400

We can now solve for b by substituting a in terms of h (using the formula for the area of a triangle) and simplifying:

Area = 1/2 * base * height

80 = 1/2 * 20 * h

h = 8

a = (2 * Area) / c

a = (2 * 80) / 20

a = 8

Substituting a and h in the Pythagorean theorem equation, we get:

8^2 + b^2 = 20^2

64 + b^2 = 400

b^2 = 336

b = sqrt(336)

b ≈ 18.33

Therefore, the length of the shortest leg of T is approximately 18.33 units.

To test the null hypothesis H0: (μ1 - μ2) = 0 versus the alternative hypothesis Ha: (μ1 - μ2) ≠ 0, we can use a two-sample z-test. The test statistic is calculated as:

\(\boxed{\textsf{ The amount shared by Nandi is \textbf{ Rs 500. }.}}\)

\(\boxed{\textsf{ The amount shared by Thabo is \textbf{ Rs 1,000. }.}}\)

Step-by-step explanation:

Given that Nandini and Thabo share Rs 1500 in the ratio 1:2 . And we need to find how much each gets . So lets take the given ratio be 1x :2x . Now here we can find the share of both as ,

\(\qquad\boxed{\boxed{\sf Share =\dfrac{ Ratio \ number }{Sum \ of\ ratio\ nos. }\times Amount }}\)

Hence here the sum of ratio numbers would be 1+2 = 3 . Here the ratio number of Nandi is 1 and that of Thaboo is 2 . So ,

Share of Nandi :-

\(\sf\implies Share =\dfrac{ Ratio \ number }{Sum\ of\ ratio\ nos. }\times Amount \\\\\sf\implies Share_{(Nandi)}= \dfrac{1}{1+2}\times Rs\ 1,500 \\\\\sf\implies Share_{(Nandi)}= \dfrac{1}{3}\times Rs\ 1,500 \\\\\sf\implies \boxed{\pink{\frak{ Share_{(Nandi)}= Rs\ 500 }}}\)

\(\rule{200}2\)

Share of Thabo :-

\(\sf\implies Share =\dfrac{ Ratio \ number }{Sum\ of\ ratio\ nos. }\times Amount \\\\\sf\implies Share_{(Thabo)}= \dfrac{2}{1+2}\times Rs\ 1,500 \\\\\sf\implies Share_{(Thabo)}= \dfrac{2}{3}\times Rs\ 1,500 \\\\\sf\implies \boxed{\pink{\frak{ Share_{(Thabo)}= Rs\ 1,000 }}}\)
