Y is inversely proportional to the square of x. if y=3 when x=3 then y =1/3 when x is _______. help me isuck at proportionals

Answers

Answer 1
Y=k(proportionally constant)/x^2
put the values of y and x
3=k/3^2
3=k/9
3*9=k
27=k

put the value of k in the first equation
Y=27/x^2
now this is the main equation

put y =1/3 and find x using main equation
1/3=27/x^2
cross multiply
x^2=81
take square root on both sides
x= ± 9 or -9 and 9

a fishing boat accidentally spills 15 barrels of diesel oil into the ocean. each barrel contains 42 gallons. if the oil film on the ocean is 2.5×102nm thick, how many square meters will the oil slick cover?

Answers

The square meters of the area the oil slick will cover is 9.6 × 10⁶ m².

What is meant by volume?

Volume is defined as the amount of three-dimensional space enclosed by a closed surface.

The liter (L) is the metric system's base volume unit, with several extended volume units also available. There are also many metric volume units based on the a cubic length dimension, including such cubic meters or cubic centimeters. Gallons and ounces are examples of imperial volume units.

Now, as per the given question;

First, we determine the entire volume of oil in gallons by multiplying the volume per barrel even by total number of barrels:

15×42 gal = 630 gal

This volume must be converted to square meters:

V = 630 gal × (0.00379 m³/ gal

V = 2.4 m³

The thickness (height) of a oil film in meters is required:

h = 250 nm × (m/10⁻⁹nm)

h = 2.5 × 10⁻⁷m

The surface area of a oil film is calculated by dividing the oil volume by height of the oil film.

A  = V/h

A  = 2.4 m³/2.5 × 10⁻⁷m

A = 9.6 × 10⁶ m²

Therefore, the area of the oil slick cover is found to be 9.6 × 10⁶ m².

I think that you are asking to simplify the expression.  An equation has an equal sign and I do not see one.

We need to distribute the -3 to everything inside of the parentheses.  

A negative times a negative is a positive.

A negative times a positive is a negative.

Hi!

To simplify this, use the Distributive Property:

Now, let's simplify the given expression:

You want to make 20 plates and have 30 bags of shredded cheese. How can you determine how much cheese to put on each plate so that each plate has the same amount of shredded cheese?

Answers

The amount of cheese in each plate = 1.5x

There are 30 bags of shredded cheese.

Let 'x' be the quantity of cheese in each bag. Then,  

The total quantity of cheese in 30 bags = 30x

Number of plates = 20 plates

We need to determine the quantity of cheese put on each plate so that each plate has the same amount of shredded cheese.

For this we just need to divide the total amount of shredded cheese by the number of plates.

The equal amount of cheese in each of 20 plates = 30x/20

                                                                                   = 3x/2

Answer: 1: (0,-5) 2: (0.5,1) 3: (1.5, -4.5) 4: (-2.5,-0.5)

Step-by-step explanation:

The solution to a system of equations is (2,-4).one equation in the system is 2x+y=0.explain how you can find a second equation for the system.then find a second equation.solve by system of equations to justify your answer

Answers

The second equation is 3x + y = 2.

Let the other equation be of the form ax + by = c, where a, b and c are constants.

Given equation is 2x + y = 0

We have, a₁ = 2 and a₂ = 1

And b₁ = a and b₂ = b

Since, both equations have a unique solution,

∴ a₁ ÷ b₁ ≠ a₂ ÷ b₂

2 ÷ a ≠ 1 ÷ b

2b ≠ a                                               … (1)

                         

Also, (2, -4) is the solution of the equations, so it will satisfy the equations

2a - 4b = c

b = (2a - c)/4

Let c=2

b = (2a - 2) ÷ 4

b = 1

Now we can take any value for a and b which satisfy eq.(1)

Let a=3

b = (2(3) - 2) ÷ 4

b = 1

Thus, a = 3 and b=1 satisfy eq.(1)

Hence the second equation is 3x + y = 2

The equations are justified by keeping the values -

2x+y=0                               ... (2)

3x+y=2                             ... (3)

From eq.(2),

y=-2x

Putting value of y in eq. (3), we get,

3x+(-2x)=2

3x-2x=2

x=2

Now, putting x=2 in eq.(2)

2(2)+y=0

y=-4

Hence, the solution is justified.

How to write an equation to determine x, the maximum number of bracelets Mr.Gonzales could buy

The given parameters are:

Budget = $42.50

Shirt = $29

Bracelet = $4.50 each

Represent the number of bracelets with x

So, we have

Shirt + Bracelet * x = Budget

This gives

29 + 4.50x = 42.50

Evaluate the like terms

4.50x = 13.5

Divide both sides b 4.50

x = 3

From the question, we are to solve for e. That is, we are to make e the subject of the given formula.

The given formula is

E/e = (R + r)/r

First cross multiply

E/e = (R + r)/r

e(R + r) = rE

Now, divide both sides of the equation by (R + r)

That is,

e(R + r)/ (R + r) = rE/ (R + r)

Standard deviation is a statistical measure of how much scores in a sample vary around the mean. The correct option is B.

What is the standard deviation?

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

Therefore, the standard deviation is a statistical measure of how much scores in a sample vary around the mean. The correct option is B.

The number added to the numerator and the denominator is 2/3.

It is given in the question that when the same number is added to the numerator and denominator of fraction 5/7, the result is 17/23.

We have to find the number added to the numerator and the denominator.

Let the number be x.

Hence, according to the data given in the question, we get,
