The option that does not describe an advantage of wind power is Wind turbines cause little disruption of ecosystems.​

Wind power is defined as the process by which the wind is utilized to generate mechanical power or electricity.

Wind power is the most sustainable, and renewable energy source which has a much smaller harmful influence on the environment as compared to the burning of fuels.

This is an environmentally friendly mechanism for synthesizing energy and electricity.

Wind turbines are not placed in large bodies of water that turbines are on land for the production of electricity.

Therefore, the option is Wind turbines cause little disruption of ecosystems.​

4, ∛64, -∛64

explanation:

they all mean the same thing

The expression [tex]y^{3} = 64[/tex] can be written as :[tex]y= \sqrt[3]{64}[/tex] or y= 4

The correct option is (II) and (VI)

The cube root of a number is the factor that we multiply by itself three times to get that number.

We have given that:

[tex]y^{3} = 64[/tex]

 we can write it as:

[tex]y= \sqrt[3]{64}[/tex]

y = [tex]\sqrt{4*4*4}[/tex]

y= 4

The answer is : [tex]y^{3} = 64[/tex]

[tex]y= \sqrt[3]{64}[/tex] or y= 4

A package has 6 cookies for $2.49

Ms. Morgan has 19 students. She wants to give each student 2 cookies, which means each package is enough for 3 students.

19 students × 2 cookies = 38 cookies is what you need

7 packages times $2.49 = $17.43

7 packages × 6 cookies = 42 cookies

42 cookies ÷ 19 students = 2.21 cookies for each student

Answer: A (1:2)

Step-by-step explanation:

Since there are 12 puppies total and 8 of the puppies are yellow labs, there must be 12 - 8 = 4 black labs. Now, the ratio of black labs to yellow labs is 4:8 because there are 4 black labs and 8 yellow labs. However, we can simplify this ratio by dividing the entire ratio by 4. In this case, we would get (4/4):(8/4), which simplifies to 1:2, which is the answer.

Step-by-step explanation:

185.193 Cm, 5.7x5.7x5.7 is the volume

The volume of the Rubik's cube is 183.51 cubic centimeters.

To find the volume of a Rubik's cube, we can use the formula V = s ³, where V represents the volume and s represents the length of each edge.

In this case, the length of each edge is given as 5.7 centimeters.

Substituting this value into the formula, we have:

V = (5.7 cm) ³

Calculating the volume:

V = 5.7 cm * 5.7 cm * 5.7 cm

V = 32.49 * 5.7

V = 183.51 cm ³

Therefore, the volume of the Rubik's cube is 183.51 cubic centimeters.

Answer:

Math sections = 20

English sections = 16

Philosophy sections = 8

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of Math sections.

y is the number of English sections.

z is the number of Philosophy sections.

Available classrooms limit the total sections of all three courses to 44.

This means that [tex]x + y + z = 44[/tex]

4 less English sections than Math sections.

This means that [tex]y = x - 4[/tex]

In any quarter student demand for the optional Philosophy course is half as many sections as English sections.

This means that [tex]z = \frac{y}{2} = \frac{x - 4}{2}[/tex]

Finding the number of Math sections:

We have both y and z as functions of x. So

[tex]x + y + z = 44[/tex]

[tex]x + x - 4 + \frac{x-4}{2} = 44[/tex]

[tex]2x + \frac{x-4}{2} = 48[/tex]

Multiplying everything by 2

[tex]4x + x - 4 = 96[/tex]

[tex]5x = 100[/tex]

[tex]x = \frac{100}{5}[/tex]

[tex]x = 20[/tex]

Then

[tex]y = x - 4 = 20 - 4 = 16[/tex]

[tex]z = \frac{y}{2} = \frac{16}{2} = 8[/tex]. So

Math sections = 20

English sections = 16

Philosophy sections = 8
