the ratio of 6 to 4 is equal to the ratio of 36 to what number​

The volume of the given sphere is 32 cm³. Thus, the correct answer is option (A) 32 cm³.

Given that the diameter of the sphere is 4 cm, the radius is half of that or 2 cm.

The formula for the volume of a sphere is:

V = (4/3)πr³

Where r is the radius of the sphere.

Here, r = 2

Substituting these values into the formula, we get:

The volume of a sphere = (4/3) × π × (2)³

The volume of a sphere  = (4/3)π(8)

The volume of a sphere  = 32π/3

Using π = 3.14, we get:

The volume of a sphere  ≈ 33.51 cm³

Therefore, the closest option to the volume of the sphere is 32 cm³.

Answer: she would make $100 after 10 hours

Step-by-step explanation:

if you divide 240 by 24 you get 10 which stands for the dollar amount per hour so 10 x 10 =100

6y-5=11

Move -5 to the other side. Sign changes from -5 to +5.

6y-5+5=11+5

6y=11+5

6y=16

Divide by 6 for both sides to get y by itself.

6y/6=16/6

Cross out 6 and 6, divide by 6 and then becomes 1*1*y=y

y=16/6

Reduce 16/6 by dividing by 2

16/2=8

6/2=3

Answer: y=8/3 or y=2 2/3

To solve the inequality -4.4 ≥ 1.6x - 3.6, you first add 3.6 to both sides, then divide by 1.6, resulting in -0.5 ≥ x. This means all values less than or equal to -0.5 make the inequality true and the graphed solution involves a filled circle at -0.5 and shading to the left.

To find the solution set for the inequality -4.4 ≥ 1.6x - 3.6, we first need to solve the inequality. To do this, we can start by adding 3.6 to both sides of the inequality:

-4.4 + 3.6 ≥ 1.6x

-0.8 ≥ 1.6x

Now, we divide both sides of the inequality by 1.6 to solve for x:

-0.8 / 1.6 ≥ x

-0.5 ≥ x

This tells us that x can take on any value that is less than or equal to -0.5. To graph this on a number line, we would plot a filled circle on -0.5 to indicate that it is part of the solution set (x is equal to -0.5), and shade everything to the left of -0.5 to indicate that all those values are solutions since they are less than -0.5.

Answer:

[tex]\frac{2}{5},\frac{1}{4},\frac{1}{10},\frac{5}{2},\frac{5}{8},\frac{4}{1},\frac{8}{5},\frac{10}{1}[/tex]

Step-by-step explanation:

Proportions are fractions that can be created using the numbers given. Let's pair each and reduce if possible.

Starting with 2:

2/5

2/8 = 1/4

2/20 = 1/10

Then 5:

5/2

5/8

5/20 = 1/4

Then 8:

8/2 = 4/1

8/5

8/20 = 2/5

Lastly 20:

20/2 = 10/1

20/5 = 4

20/8 = 5/2

So, we can see some are repeating, hence the unique proportions are:

2/5, 1/4, 1/10, 5/2, 5/8, 4/1, 8/5, 10/1

The possible proportions using the numbers 2 5 8 and 20 are:

1. 2:5 = 8:20

2. 2:8 = 5:20

3. 5:20 = 2:8

4. 8:2 = 20:5

5. 20:5 = 8:2

6. 5:2 = 20:8

To create all possible proportions using the numbers 2, 5, 8, and 20, you can set up ratios and see how you can pair these numbers.

A proportion is essentially an equation that states two ratios are equal.

Here are some possible proportions you can create:

1. 2:5 = 8:20

  (This is a direct proportion where both ratios reduce to 2:5.)

2. 2:8 = 5:20

  (Again, this is a direct proportion where both ratios reduce to 1:4.)

3. 5:20 = 2:8

  (This is just another way to write the second proportion.)

4. 8:2 = 20:5

  (This is an inverse proportion where the first ratio is the reciprocal of the second.)

5. 20:5 = 8:2

  (This is just another way to write the fourth proportion.)

6. 5:2 = 20:8

  (This is an inverse proportion where the first ratio is the reciprocal of the second.)

7. 20:8 = 5:2

These are all the possible proportions you can create using the numbers 2, 5, 8, and 20. Note that in each proportion, you can switch the positions of the numbers (e.g., 2:5 = 8:20 is the same as 5:2 = 20:8), but the ratios remain the same.

Step-by-step explanation:

4x^2-5y

Final answer:

The question involves using algebraic expressions to square a number by multiplying it by itself and then subtracting the product of another number multiplied by five. it could be represented as 4a2 - 5b.

Explanation:

The question involves understanding how to manipulate algebraic expressions with integers and variables. When we talk about raising a number to a power, such as squaring a number, we are multiplying that number by itself. For example, the exponent is '2' and the base is the number '5', so squaring it would give us 52 = 5x5 = 25. When we consider an equation involving the square of one number and the multiplication of another, we have to apply these rules of exponents and multiplication.

In mathematics, we often encounter expressions where we square a number by raising it to the power of '2'. This also applies to variables. For instance, (2x)2 = 4x2. Remember, whether numbers are positive or negative, squaring them will always give a positive result because multiplying two negative numbers yields a positive product.

If a question involves subtracting five times one number from four times the square of another number, it could be represented as 4a2 - 5b. Here, a is being squared while b is simply being multiplied by five.

Thanks for letting me help!!

The distributive property is a math concept that allows multiplication to be distributed over addition or subtraction. It does not directly apply to the expression 16 + 36, as there's no multiplication involved. However, for an expression with multiplication, such as 4(16 + 36), it would simplify to 208 using the distributive property.

The distributive property is a fundamental concept in mathematics that allows us to simplify expressions involving multiplication distributed over addition or subtraction. It states that for any numbers a, b, and c, the equation a(b + c) = ab + ac holds true. This property makes it easier to work out expressions without having to perform operations within parentheses first.

In the given expression 16 + 36, however, there's no multiplication being distributed over addition, thus the distributive property doesn't directly apply here. But if we are to apply the distributive property to a multiplication over an addition, such as 4(16 + 36), then we would use the distributive property to get 4*16 + 4*36, which simplifies further to 64 + 144 = 208.

No, the given equation y = 0(x-4)² + 3 is not a quadratic function.

In algebra, a polynomial function with one or more variables in which the highest-degree term is of the second degree is known as a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic.

Given function is y = 0(x-4)² + 3. Solve the functions:-

y = 0(x-4)² + 3

In the second term, the value of the whole term will become zero.

y = 0 + 3

y = 3

The value of y is 3 which is a constant term. Therefore, the given equation y = 0(x-4)² + 3 is not a quadratic function.

110.313 - 38.25 = $72.063

4. %11.75

72.063 / 612.85 = 0.11758

Courtney's weekly earnings before taxes are $612.85. After an 18% tax, her earnings are $502.54, which becomes $464.29 after saving $38.25. The paycheck's remaining percentage is 75.76%, and her monthly earnings after taxes average $2,186.05.

Courtney earns $14.42 per hour and works 42.5 hours a week. To calculate her weekly earnings before taxes:

Weekly earnings = Hourly wage times Hours worked per week
Weekly earnings = $14.42 times 42.5
Weekly earnings = $612.85

To find out how much she makes after an 18% tax deduction:

Taxed amount = Weekly earnings times Tax rate
Taxed amount = $612.85 times 0.18
Taxed amount = $110.31

Earnings after tax = Weekly earnings - Taxed amount
Earnings after tax = $612.85 - $110.31
Earnings after tax = $502.54

After Courtney saves $38.25, her disposable weekly income is:

Money left to spend = Earnings after tax - Savings
Money left to spend = $502.54 - $38.25
Money left to spend = $464.29

Now, to calculate the percentage of paycheck left after taxes and savings:

Percentage left = (Money left to spend / Weekly earnings) times 100
Percentage left = ($464.29 / $612.85) times 100
Percentage left = 75.76%

For her monthly earnings after taxes, considering an average of 4.35 weeks per month:

Monthly earnings after taxes = Earnings after tax times Average weeks per month
Monthly earnings after taxes = $502.54 times 4.35
Monthly earnings after taxes = $2,186.05

Step-by-step explanation:

In the right triangle, the hypotenuse is 25 feet long. The area of this triangle is 84 square feet.

Let x feet and y feet be the lengths of triangle's legs.

By the Pythagorean theorem,

[tex]x^2+y^2=25^2\\ \\x^2+y^2=625[/tex]

The area of the right triangle is half the product of its legs, thus

[tex]84=\dfrac{1}{2}xy\\ \\xy=168[/tex]

Solve the system of two equations:

[tex]\left\{\begin{array}{l}x^2+y^2=625\\ \\xy=168\end{array}\right.[/tex]

From the second equation:

[tex]x=\dfrac{168}{y}[/tex]

Substitute it into the first equation:

[tex]\left(\dfrac{168}{y}\right)^2+y^2=625\\ \\168^2+y^4=625y^2\\ \\y^4-625y^2+168^2=0\\ \\D=(-625)^2-4\cdot 168^2=(625-2\cdot 168)(625+2\cdot 168)=289\cdot 961=17^2\cdot 31\\ \\\sqrt{D}=17\cdot 31=527\\ \\y^2_{1,2}=\dfrac{-(-625)\pm 527}{2}=49,\ 576\\ \\y_1=7,\ y_2=-7,\ y_3=24,\ y_4=-24[/tex]

The length of the leg cannot be negative, so
