how do i rewrite 14/32 to make it the simplist
Answer:
You would need to divide "14/32" by 2, since 2 in this problem is your "gcf" so:
14 / 2 = 7
32 / 2 = 16
So, it's 7/16.

Hi
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}.
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}.

Answer:
x=-3
Step-by-step explanation:
-54= 6(x-6)
switch sides = 6(x-6)=-54
divide both sides by 6 =x-6=-9

Ok I'm not sure about the theorem I thought it was just corresponding angles theorem but to get the x value set up an equation with your given info that is equal to 120.
2x+10=120
Subtract 10 from both sides.

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?
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.

8 and 4 = [?] (what it says) 8, 40, 24
8 and 10 = [?] (what it says) 8, 40, 24
Answer:
8 and 4 = 8
8 and 10 = 40
Step-by-step explanation:
The least common multiple is the smallest value that both numbers equal when you look at their multiples.
The multiples of 8 are 8, 16, 24, 32, 40...
The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32...
The multiples of 10 are 10, 20, 30, 40...
The first multiple 8 and 4 have in common is 8.
The first multiple 8 and 10 have in common is 40.
