» Variables y and x have a proportional relationship, where y = 9 when x = 3. What is the value of x when y = 36? Enter your answer in the box.

Answer:[tex] \underline{ \boxed{ \orange{\bold{ 12}}}}[/tex]

— — — — — — — — — —

Steps-by-step explanation:

Since variables y and x have a proportional relationship, then the equation is in the form y=kx.

Given: y = 9 when x = 3.

First, we need to find the constant of variation (k) by substituting the given to the equation of variation.

[tex] \tt y = kx \\ \tt \: \: \: \: 9 = k(3) \\ \tt k= \frac{9}{3} \\ \tt k= \blue{3}[/tex]

The constant of variation (k) is 3. So, find the value of x when y = 36.

[tex] \: \: \: \: \tt y = 3x \\ \tt \: 36 = 3x\\ \tt \: \: \: \: \: x = \frac{36}{3} \\ \tt \: \: \: \: \: \: \: x= \underline{ \boxed{ \purple{ \tt{12}}}}[/tex]

Hence the unknown value (x) is 12.

how is multiplying two decimals different from multiplying a whole number and a decimal

Answers

Answer:

So multiplying decimal and whole number means it will always equal as a decimal. But multiplying decimal with decimal means could equal whole or decimal number

Step-by-step explanation:

Answer:

Essentially, they are same thing

Step-by-step explanation:

For example, 3 x 0.4 = 1.2

0.3 x 0.4 = 0.12

The only thing that changes are the amount of numbers behind the decimal. So when multiplying decimals, you just multiply like normal (3 x 4 = 12), then you count the amount of decimal spaces (two) and you take the number (12) and move the decimal place to the left twice. 12.0 would go to 1.2 if multiplying by a tenth.

The sum of two
numbers is 152 and
their difference is 40.
Find the two numbers.

Answers

Answer: The numbers are 96 and 56

Step-by-step explanation:

x+y=152

x-y=40

If you subtract the equations from one another, you will get

x+y=152

-(x-y)=40

So, 2y=112, making y=56

If you plug y=56 into x+y=152, you will get x=96

Write an equation for the translation of y = 4/x that has the given asymptotes x = 2, y = 2

Answers

According to the given asymptotes, the equation for the translation of the function is:

[tex]y = \frac{4}{x - 2} + 2[/tex]

What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

In this problem, the function is:

[tex]y = \frac{4}{x}[/tex]

The vertical and horizontal asymptotes are, respectively, given by: x = 0, y = 0.

To have the desired asymptotes, the function has to be shifted 2 units to the right and 2 units up, hence it is given by:

Examine the data below for a stalk of corn. Logarithmic regression Use logarithmic regression to find an equation of the form y = a b ln(x) to model the data. A = b =.

Answers

The value of a and b for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.

What is logarithmic regression?

Logarithmic regression is a type of regression which is used to model the statement in which the growth or decay initially at rapid rate, and then slow down with respect to time.

The data of the table for the day and height of the stalk of corn is listed below.

Day (x)                9    12    22    40    

Height (y) in        5    17    45    60  

Mean of x values,

[tex]m_x=\dfrac{9+12+22+40}{4}\\m_x=17.5581[/tex]

Mean of y values,

[tex]m_y=\dfrac{5+17+45+60}{4}\\m_y=31.75[/tex]

For the above table, the value of correlation coefficient is 0.99133. For these values, the logarithmic regression can be given as,

[tex]y = -76.2038+37.6735\ln(x)[/tex]

Compare it with the following logarithmic regression equation, we get

[tex]y = a+b\ln(x)[/tex]

[tex]a=-76.2038\\b=37.6735[/tex]

Hence, the value of a and b for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.

Answers

Answer:

Timothy invested $2500 in 3% account and $5000 in the 2% account

Step-by-step explanation:

Required equations are:

x + y = 75000.03x + 0.02y = 175

Solve the system by elimination, multiply the second equation by 50 and subtract the first one:

50(0.03x) + 50(0.02y) - x - y = 50(175) - 75001.5x - x = 12500.5x = 1250x = 2500

If 2 + x/8 = 2 then what is the value of 9x - 3?

Answers

Answer:

-3

Step-by-step explanation:

assuming that the x is the same in both problems, to get 2 as your solution, in the first problem x÷8 would have to equal 0. so x would have to be 0. sense 0 + 2 equals 2.

Then plug 0 into x in the first equation to check your work, and if it equals the answer givin to you (2), plug 0 into the equation you are trying to solve.

so 9×0 is 0, then 0 - 3 would give you -3

if 1 pound=Rs.135 and dollar 1=Rs105 then convert pound 63 into dollar

Answers

Answer:

81

Step-by-step explanation:

63×135=8505

8505÷105=81#

In 63 pounds, there are equivalent 81 dollars.

What is unit conversion?

A unit conversion expresses the same property as a different unit of measurement.

For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.

Given is that -

1 pound = Rs.135

1 dollar = Rs. 105

Now, we can write that 1 rupee as -

Rs. 1 = 1/105 dollar

So, in 1 pound we can write -

1 pound = 135 x 1/105 dollars

63 pounds = 63 x 135 x 1/105 = 81 dollars

Therefore, in 63 pounds, there are equivalent 81 dollars.

What was the Enlightenment, and how did it change they way people viewed government? Write your answer in complete sentences.

Answers

Answer:

The Enlightenment was a seventeenth- and eighteenth-century intellectual movement that aimed to better society via fact-based reasoning and investigation. The Enlightenment introduced secular ideas to Europe, changing people's perceptions of problems like liberty, equality, and individual rights. Today, such ideas are the bedrock of the world's most powerful democracies.

Step-by-step explanation:

two ideas that emerged from the Enlightenment:

Intellectuals like Jean-Jacques Rousseau and John Locke introduced the idea that no monarch should have absolute authority. Both claimed that leaders' authority came from the people, not from God. And, according to Locke, if people disagreed with their leader, they had the right to have their government replaced with one that honored their rights.

Pre-Enlightenment Equality Powerful individuals known as the nobility had exclusive privileges to buy land, avoid taxes, and hold privileged jobs across Europe, while the lowest elements of society battled to make ends meet. The Enlightenment questioned this system, with intellectuals such as John Locke arguing that all men are created equal and that no one should be born with more power than another.

what are the parts of the surface area ?

rest assured, there is no such thing like a general equation for the surface area of a prism.

well sure, there could be, but there are so many different variations, to describe them would be more complicated than the formula. so, we only have a general approach for the volume of such regular prisms (ground area × height).

but for the surface area we just have to break this problem into smaller problems we can easily solve and then add the results together.

so,

we see, there are 5 sides of this special prism.

top, bottom, left, right and front.

so, we need to calculate these 5 areas and simply add them up.

left and right are rectangles. one is

11×18 = 198 in²,

the other is

12×18 = 216 in², together they are 414 in².

the front is a rectangle

8×18 = 144 in²

top and bottom are equal triangles. each is

8 × height / 2

or per Heron's formula

A = sqrt(s(s -a)(s - b)(s -c)) where s = (a + b + c)/2

our s here is

s = (8 + 11 + 12)/2 = 15.5

A = sqrt(15.5×7.5×4.5×3.5) = sqrt(1830.9375) =

= 42.78945548... in²

both together are 85.57891095... in²

so, the total surface area is

414 + 144 + 85.57891095... = 643.578911... in²

if we need to round to e.g. whole square inches, this would be

644 in²
