who walks at a faster rate: someone who walks 60ft in 10sec or someone who walks 42ft in 6sec

Answer:

25

Step-by-step explanation:

The kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules

From the question, we are to determine the kinetic energy of the ball

From the given equation for the velocity,

[tex]v = \sqrt{\frac{2K}{m} }[/tex]

We will make K the subject of the equation

 [tex]v = \sqrt{\frac{2K}{m} }[/tex]

Take the squares of both sides

[tex]v^{2} ={\frac{2K}{m} }[/tex]

Multiply both sides by m

[tex]mv^{2} ={\frac{2K}{m} } \times m[/tex]

[tex]mv^{2} =2K[/tex]

∴ [tex]K = \frac{1}{2} mv^{2}[/tex]

Now, for the kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second

That is,

m = 2 kg

and v = 5 m/s

Putting the parameters into the equation, we get

[tex]K = \frac{1}{2} \times 2 \times 5^{2}[/tex]

K = 25 J

Hence, the kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules

Select the correct answer from each drop-down menu. The velocity, v, in meters/second, of an object with a mass of m, in kilograms, and kinetic energy of K, in joules, is given by this equation.

[tex]v = \sqrt{\frac{2K}{m} }[/tex]

Use the equation to complete this statement. The kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second is joules.

Answer:

Hey buddy, here is your answer. Hope it helps you.

Step-by-step explanation:

144 students enter a spelling bee contest.

Step 1

For the semi final round we are told that only 1/6 of the group will make it into that round.

This is calculated as

1/6 × 144/students = 24 students.

This means that only 24 students would make it into the semi final rounds.

Step 2

We are also told in the question that only 2/3 of THAT group would make it into the final round.

" THAT" group been referred to in the question means the number students that made it to the semi final round

This is calculated as

2/3 of that group( the group that made it to the semi finals)

= 2/3 × 24 students

= 16 students.

Therefore, the number of students that will enter the final round of the spelling bee is 16 students.

Answer:

I think its b I'm pretty sure

Answer:

−2(−9x+5)−4x=2(x−5)−4

Step 1: Simplify both sides of the equation.

−2(−9x+5)−4x=2(x−5)−4

(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)

18x+−10+−4x=2x+−10+−4

(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)

14x+−10=2x+−14

14x−10=2x−14

Step 2: Subtract 2x from both sides.

14x−10−2x=2x−14−2x

12x−10=−14

Step 3: Add 10 to both sides.

12x−10+10=−14+10

12x=−4

Step 4: Divide both sides by 12.

Answer: B. X+26<2x+16

Step-by-step explanation:

Let x be the number of lemonade Kaylee needs to sell to make a higher profit than Jason.

Given: Jason has made $26. he charge $1 per lemonade.

Total earnings after x lemonades = $26+($1) x

= $(26+x)

Kaylee has made $16. he charge $2 per lemonade.

Total earnings after x lemonades = $16+($2) x

= $(16+2x)

Required inequality : (16+2x)> (26+x)

i.e. correct option is B.

Answer:

none of them the correct answer is (x,y) (5,0)

Answer:

y=x times factor of 12 abstracted by -93

Step-by-step explanation:

The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1.

A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

A linear equation or function is given as ;

y = mx + b

Now,

At x = 0 ⇒ y = b so it will be a y-intercept.

As per the given, y = x

The x's coefficient is 1 thus slope will be 1.

Or, y/x = 1

Hence "The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1".

Step-by-step explanation:

Answer:

The roots of the equation is real and repeated

Step-by-step explanation:

Here, we want to describe the nature of the roots of the given quadratic equation

To get the nature of the roots, we find the discriminant of the equation

The discriminant is;

b^2 - 4ac

In this case, b = -28 , a = 49 and c = 4

The discriminant is thus;

-28^2 - 4(49)(4)

= 784 - 784 = 0

Since the discriminant is zero, this means that the quadratic equation has real roots which are the same

(-4,-6)

Step-by-step explanation:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The point of intersection between the two equations is (-4, -6).

The graph is given below.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 6 is an equation.

We have,

y = 2x + 2

y = x - 2

Now,

The point of intersection.

2x + 2 = x - 2

2x - x = -2 - 2

x = -4

Putting in y = 2x + 2

y = 2 x -4 + 2

y = -8 + 2

y = -6

(-4, -6) is the point of intersection.

Now,

The graph of the equation is given below.

Thus,

The point of intersection between the two equations is (-4, -6).

The situation shows correlation without causation

Step-by-step explanation:

The given data are;

Weight y     [tex]{}[/tex]            Miles Per Gallon

42     [tex]{}[/tex]                           18

36     [tex]{}[/tex]                           12

.     [tex]{}[/tex]                                x

24     [tex]{}[/tex]                            0

The first difference of the data = 42 - 36 = 36  - 30 = 30 - 24 = 6

18 - 12 = 12 - 6 = 6 - 0 = 6

The first difference of the data is constant and equal to 6

Therefore, the graph is a straight line graph with y-intercept = 24 and slope given by the rate of change of the weight to the miles per gallon of fuel consumption as follows;

The rate of change of the weight to the miles per gallon of fuel consumption is given as follows;

(42 - 24)/(18 - 0) = 1

Therefore, the points of the data fit into the straight line and the data of the situation shows correlation

In order to show causation, and to rule out other possible causes for the rise in MPG, a separate experiment will be required whereby the cause for the rise in MPG can be determined.

Answer:

The situation shows correlation with causation.

Step-by-step explanation:

A correlation between two variables is a measure of the strength of the association between them.

It can be seen from the scatter plot that as the weight of the car increases, the miles per gallon decreases.

Causation between variables indicates that one of the variables causes the other variable to occur. Causation between variables always implies correlation.

The weight of the car affects the miles per gallon because cars that weigh more require more power to move. Hence, heavier cars get lower miles per gallon of fuel.

Therefore, the situation shows correlation with causation.
