To find the quotient of 3 divided by 1/6 , multiply 3 by

Answers

Answer:

To find the quotient of 3 divided by 1/6 you must multiply by the reciprocal of the fraction, in this case it is 6.

So you would rewrite it as,

3*6=18

So your answer is multiply 3 by 6.

P.S * represents multiplication.

To yield the quotient, 6 has to get multiply by 3.

What is simplification of an expression?

Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression.

For the given situation,

The expression is the quotient of 3 divided by 1/6,

⇒ [tex]\frac{3}{\frac{1}{6} }[/tex]

Step-by-step explanation:

Which statements represent the function of the yearly cost in dollars, y, based on x, the number of game tokens purchased for a member of the arcade? Select three answers.
The slope of the function is $1.00.
The y-intercept of the function is $60.
The function can be represented by the equation y = y equals StartFraction 1 Over 10 EndFraction x plus 60.x + 60.
The domain is all real numbers.
The range is {y| y ≥ 60}.

Answers

The answers are :

a) The value of c or y - intercept is $60.

b) The domain is all real numbers.

c) The range will be equal to {y | y ≥ 60}.

What is the function ?

A function is a relationship between inputs and outputs where each input has precisely one output and the output can be linked to its input.

It is given that :

Yearly cost in dollars = y

Number of game tokens purchased for a member of the arcade = x

We know that :

The function is represented by equation :

y = [tex]\frac{x}{10}[/tex] + 60

Comparing it with the general equation we get :

Slope (m) = [tex]\frac{1}{10}[/tex]

and y - intercept (c) = $60

Now , when x = 0 then :

y = [tex]\frac{1}{10}[/tex] × 0 + 60

y = 0 + 60

y = $ 60

The domain is x ≥ 0. The domain will be all real numbers.

and y ≥ 60

The range will be :

{y | y ≥ 60}

Therefore , the answers are :

a) The value of c or y - intercept is $60.

b) The domain is all real numbers.

c) The range will be equal to {y | y ≥ 60}.

The height h, in feet, of objects such as thrown balls can be modeled as a function of time t, in seconds, as h(t)=−16t2+v0t+h0, where the initial upward velocity is v0, in feet per second, and the initial height is h0, in feet. Marla and Kerry are practicing lacrosse tosses. Marla throws a ball from a height of 6 feet with an initial vertical velocity of 40 feet per second. At the same instant, Kerry throws a ball from a height of 5 feet with an initial vertical velocity of 50 feet per second. Which ball is in the air longer and by how many seconds more?

Answers

Answer:

Kerry's ball stays longer in the air than Marias ball by an extra 0.582 seconds

Step-by-step explanation:

The equation that models the height, h, in feet of object thrown modeled as a time function is given as follows;

h(t) = -16t² + v₀·t + h₀

Where;

v₀ = The velocity upwards (vertical velocity)

h₀ = The initial height of the object in feet

The given parameters are;

The initial height from which Maria throws a ball = 6 feet

The initial vertical velocity with which Maria throws the ball = 40 feet per second

The initial height from which Kerry throws a ball = 5 feet

The initial vertical velocity with which Kerry throws the ball = 50 feet per second

For Maria, from the equation for the height of the object, we have;

h(t) = -16t² + v₀·t + h₀

Where for Maria, we have;

h₀ = 6 feet

v₀ = 40 ft/s

Substituting gives;

h(t) = -16 × t² + 40 × t + 6 = -16·t² + 40·t + 6

h(t) = -16·t² + 40·t + 6

The time it takes for the ball to go up and come back down again is given by the value of t, when h = 0 (ground level) as follows;

0 = -16·t² + 40·t + 6

16·t² - 40·t - 6  = 0

From the quadratic formula, we have

[tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex]

[tex]t = \dfrac{40\pm \sqrt{(-40)^{2}-4\times 16 \times (-6)}}{2\times 16} = \dfrac{40 \pm 8 \times \sqrt{31} }{32} = \dfrac{5}{4} \pm \dfrac{\sqrt{31} }{4}[/tex]

t ≈ 2.64 s or -0.14 s

Therefore, the time the ball spends in the air ≈ 2.64 s

For Kerry,  we have;

h₀ = 5 feet

v₀ = 50 ft/s

Substituting gives;

h(t) = -16 × t² + 50 × t + 5 = -16·t² + 50·t + 5

h(t) = -16·t² + 50·t + 5

Which gives;

16·t² - 50·t - 5  = 0

From the quadratic formula, we have

[tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex]

[tex]t = \dfrac{50\pm \sqrt{(-50)^{2}-4\times 16 \times (-5)}}{2\times 16} = \dfrac{50 \pm 2 \times \sqrt{705} }{32} = \dfrac{25}{16} \pm \dfrac{\sqrt{705} }{16}[/tex]

t ≈ 3.222 s or -0.097 s

he time the ball spends in the air ≈ 3.222 s

Therefore, Kerry's ball that spends approximately 3.222 seconds stays longer in the air than Maria's ball that spends approximately 2.64 seconds in the air.

The difference in the two time duration is 3.222 - 2.64 = 0.582

Kerry's ball stays longer in the air than Marias ball by an extra 0.582 seconds.

What is the slope of a line that is parallel to y=4/7x-2

Answers

Two lines are parallel if the have the same slope. To find the slope of the line parallel to the line y=4/7x-2 we need to get the line into slope-intercept form (y = mx + b), but the line is already in that form, so the slope is m = 4/7.

Because two lines are parallel if the have the same slope, we concluded that the slope of the parallel to y=4/7x-2 is m = 4/7.

Elena works out on a treadmill. She uses a program that combines running and walking. She knows that she runs .2 miles and she walks . 1 miles per minute. At the end of the workout, the treadmill showed her workout distance was 8 miles Give three possible combinations of walking and running times that would result in Elena having a workout distance of 8 miles Write an equation that will relate the number of minutes Elena runs and walks to the total distance of her workout

Answers

Answer:

s = 2t₁ + t₂

3 possible combinations:

t₁ = 0 min , t₂ = 8 min

t₁ = 1 min , t₂ = 6 min

t₁ = 2 min , t₂ = 4 min

Step-by-step explanation:

The distance covered by a body in uniform motion is given by the following equation:

s = vt

where,

s = distance

v = speed

t = time

For running:

s = s₁

t = t₁

v = 2 miles/min

Therefore,

s₁ = 2t₁

For walking:

s = s₂

t = t₂

v = 1 miles/min

Therefore,

s₂ = t₂

And the total distance will be:

s = s₁ + s₂

s = 2t₁ + t₂

where,

s = total distance covered in miles

t₁ = running time in min

t₂ = walking time in min

Now, the total distance is given as 8 miles:

8 = 2t₁ + t₂

So, the 3 possible combinations of time to satisfy this equation can be:

t₁ = 0 min , t₂ = 8 min

t₁ = 1 min , t₂ = 6 min

t₁ = 2 min , t₂ = 4 min
