A person riding in an elevator travels 180 feet in 30 seconds. What equation represents this relationship? How many feet will this person travel in 10 seconds?

Answer:

[tex]y=x+8[/tex]

Step-by-step explanation:

Slope of straight line can be calculated as

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here [tex](x_1, y_1)=(-3, 5) \ and \ (x_2, y_2) = (2, 10)[/tex]

[tex]m =\frac{10-5}{2-(-3)}\\m=1[/tex]

Equation of straight line in slope intercept form is

[tex]y-y_1=m(x-x_1)\\y-5=(x+3)[/tex]

[tex]y=x+8[/tex]

Answer:

The length of the sky lift is 3.387.05 ft

Step-by-step explanation:

By an online search, i  found that the sky lift rises at an angle of 20.75 degrees.

Then we can think on a triangle rectangle, such that:

One cathetus is 1200ft, this is the opposite cathetus to the angle of 20.75°

The length of the ski lift would be the hypotenuse of this triangle rectangle.

Then we can use the relationship:

Sin(a) = opposite cathetus/hypoteuse.

such that:

a = 20.75°

opposite cathetus = 1200ft

then:

sin(20.75°) = 1200ft/hypotenuse

hypotenuse = 1200ft/sin(20.75°)  = 3.387.05 ft

The length of the sky lift is 3.387.05 ft

Answer:

x= −1/2 y+7

Step-by-step explanation:

Let's solve for x.

2x+y=14

Step 1: Add -y to both sides.

2x+y+−y=14+−y

2x=−y+14

Step 2: Divide both sides by 2.

Answer:

12

Step-by-step explanation:

Midsections are half of the length of the base of the triangle. 12 - 2 = 10 and half of 20 would be 10.

Answer:

Its most likely 8 because the second layer is 10 and it goes -2 so 10 - 2 is 8

Answer:

A={5,1,-7}

Step-by-step explanation:

domain = x

choose domain {-2,0,4} to 2x+y=1

range = y

range is

2(-2)+y =1 ,y =5

2(0)+y=1, y= 1

2(4)+ y=1, y=-7

range = {5,1,-7}

The tax amount for the dinner bill can be calculated with the given expression.The tax amount for the dinner bill given by Mr jaxon is $8.

Given-

Total Total amount of the bill dinner is $102.

Tips given by Mr. Jaxon [tex]t[/tex] percent is 25 percent of the dinner bill before tax.

The expression for the tip amount [tex]t[/tex] can be model as,

[tex]t=0.25(102-x)[/tex]

Here [tex]x[/tex] is the tax amount.

Put the value of  the tip in the above expression we get,

[tex]23.5=0.25(102-x)[/tex]

Divide by 0.25 both side, we get,

[tex]\dfrac{23.5}{0.25} =(102-x)[/tex]

[tex]94 =(102-x)[/tex]

Rewrite the equation for the [tex]x,[/tex]

[tex]x=102-94[/tex]

[tex]x=8[/tex]

Thus, the tax amount for the dinner bill given by Mr jaxon is $8.

∡BCE = 60

Step-by-step explanation:

Here, we want to find the angle marked BCE

From our diagram, the angle marked BCE is y

Looking at triangle BCE, we have the right angle, an angle measure of 30 and the angle marked y which we say is BCE

mathematically, the sum of all these will give 180 as the sum f the interior angles of a triangle is 180

Thus, we have that;

y + 30 + 90 = 180

y = 180-120

y = 60

Answer:

See explanations below

Step-by-step explanation:

Given the quadrilateral ABCD

A(3,0),B(-4,4),C(-7,0) and D(-3,-5)

The sides of the quadrilateral are AB, BC, CD and AD

The midpoint coordinate of the line is expressed as;

X = x1+x2/2

Y = y1+y2/2

Given A(3,0),B(-4,4)

Midpoint of AB = (3-4/2, 0+4/2)

midpoint of AB = (-0.5, 2)

Given B(-4, 4),C(-7, 0)

Midpoint of BC = (-4-7/2, 4+0/2)

midpoint of BC = (-11/2, 4/2)

Midpoint of BC = (-5.5, 2)

Given C(-7, 0) D(-3,-5)

Midpoint of CD = (-7-3/2, 0-5/2)

midpoint of CD = (-10/2, -5/2)

Midpoint of CD = (-5, -2.5)

Given A(3,0),D(-3, -5)

Midpoint of AD = (3-3/2, 0-5/2)

midpoint of AD = (0/2, -5/2)

Midpoint of AD = (0, -2.5)
