The right-hand rule is used to determine the direction of angular velocity and angular momentum when an object rotates 180 degrees. If the rotation is counterclockwise, the thumb points up, and if clockwise, it points down.
The Counterclockwise and Clockwise Rules for 180 degrees of rotation are principles used to determine the direction of angular velocity and angular momentum in a rotating system.
When an object rotates counterclockwise as viewed from above, the right-hand rule can be used to find the direction of its angular quantities.
To do this, point your thumb upward while the fingers of your right hand curl in the direction of rotation; your thumb will then point in the direction of the angular velocity vector and angular momentum.
Conversely, if the rotation is clockwise, the thumb would point downward, indicating the opposite direction for angular velocity and angular momentum.
An understanding of these rules is crucial in physics, especially when studying rotational motion and the effects of torque.

Approximate the square root of 39 to the nearest whole number
To approximate the square root of 39 to the nearest whole number, we can use the method of estimation. The estimated value of the square root of 39 is a little less than 6.
Explanation:To approximate the square root of 39 to the nearest whole number, we can use the method of estimation. We know that the square root of 36 is 6, and the square root of 49 is 7. Since 39 is closer to 36, we can estimate the square root of 39 to be a little less than 6.

Which graph represents the line
10x + 5y = 20?
Answer:
Option 1.
Step-by-step explanation:
The given equation of the line is 10x + 5y = 20
Now we will convert this equation into y-intercept form
10x + 5y = 20
5y = 20 - 10x
y = [tex]\frac{1}{5}[/tex] (20 _ 10x)
= -2x + 4
y-intercept of the line is 4 which gives us hint that graph (1) or (2) may be the correct option.
Since slope is (-2)
So from graph (1) slope of the line passing through (0,4) and (-2,0) = [tex]\frac{4.0}{0+2}[/tex] = 2
Therefore, graph A is not the answer.
For graph (2) slope of the graphed line passing through (0,4) and (2,0) = [tex]\frac{4-0}{0-2}[/tex] = (-2)
So graph (2) is representing the line y = -2x +4

Which are perfect cubes? Check all that apply. 64 x^16 8x^3 27x^4 81x^6 125x^9
The perfect cubes from the given options are 64x^16, 8x^3, 81x^6, and 125x^9 as they can all be expressed as the cube of an integer or a product of an integer and variable raised to an exponent that is a multiple of three.
Explanation:The question is asking us to identify which expressions are perfect cubes. A perfect cube is a number that can be expressed as the cube of an integer. The expression for a perfect cube with variables is x3n, where n is a non-negative integer. We apply this principle to the options given:
64x16 is a perfect cube because 64 is 43 and 16 is 3 times 5, making the whole expression (4x5)3.8x3 is a perfect cube because 8 is 23 and 3 is 3 times 1, making the whole expression (2x)3.27x4 is not a perfect cube because 4 is not a multiple of 3.81x6 is a perfect cube because 81 is 34 and 6 is 3 times 2, making the whole expression (3x2)3.125x9 is a perfect cube because 125 is 53 and 9 is 3 times 3, making the whole expression (5x3)3.Therefore, the perfect cubes from the options given are 64x16, 8x3, 81x6, and 125x9.
There are 275 people in the movie theater. The same number of people are seated in each of the 5 sections. How many people are seated in each section?
Answer:
People are seated in 1 section = 55.
Step-by-step explanation:
Given : There are 275 people in the movie theater. The same number of people are seated in each of the 5 sections
To find : How many people are seated in each section?
Solution : We have given
Total people in theater = 275 .
Total section = 5.
People are seated in 5 section = 275.
People are seated in 1 section = [tex]\frac{275}{5}[/tex].
People are seated in 1 section = 55.
Therefore, People are seated in 1 section = 55.

Solve for h.
−110=13+3(4h−6)
Answer:
the value of h is, -8.75
Step-by-step explanation:
The distributive property says that:
[tex]x \cdot (y+z) = x\cdot y+ x\cdot z[/tex]
Given the equation:
[tex]-110=13+3(4h-6)[/tex]
Apply the distributive property we have;
[tex]-110=13+12h-18[/tex]
Combine like terms;
[tex]-110=12h-5[/tex]
Add 5 to both sides we get;
[tex]-105=12h[/tex]
Divide both sides by 12 we get;
-8.75 = h
or
h = -8.75
Therefore, the value of h is, -8.75

A heartbeat take 0.8 second. How many is this written as a fraction ?
Answer: 8/10
Step-by-step explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.
Therefore, 0.8 can be written as the fraction 8/10.
