If the mountain is 1,200 feet tall, find the length of the ski lift. *
360 ft
452 it
Ski Lint
Mountain
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

Step-by-step explanation:
Write the equation of the line that passes through (-3,5) and (2, 10) in slope-intercept form.
Oy=x+8
Oy=x-8
Oy= -5x - 10
Oy=-5x + 20
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:
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.

Mr. Jaxon tips 25% of the dinner bill before tax. The expression 0.25(102−x) models the tip amount for a total bill of $102, where x is the dollar amount of tax. Mr. Jaxon tips $23.50. How much is the tax?
Answer: 1.02
Step-by-step explanation:because it is
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.

The diagonals of kite ABCD intersect at E. If ∡EBC=30°, what is ∡BCE?
Answer:
∡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

Pls help and SHOW WORKINGS it due asap.
Answer:
C
Step-by-step explanation:
The x coordinate of the rest stop:
1/2 × (the sum of the x coordinates of the highschool and the stadium)
= 1/2 × (3+7)
= 1/2 × 10
= 5
The y coordinate of the rest stop:
- Same thing i did for the x coordinate, but use the y coordinates.
1/2 × (the sum of the y coordinates of the highschool and the stadium)
= 1/2 × (4 + 1)
= 1/2 × 5
=5/2
So the coordinate of the rest stop would be (5, 5/2).
Next for the distance, i used the pythagoras theory so it's like this:
a^2 + b^2 = c^2
Here you plot the highschool and the stadium on the coodinate plane, then connect the two dots to make a right triangle. The height of the triangle will be 3, and the base would be 4. So a=3, b=4 in the equation.
3^2 + 4^2 = c^2
9 + 16 + c^2
25 + c^2
c = 5
(Note that this isn't the real answer cuz at the end of the question it said that one UNIT equals 6.4 MILES.)
So the final answer is 5 × 6.4, which is 32. The answer is C.

A family eats at a restaurant. The bill is $42. The family leaves a tip and spends $49.77.
1. How much was the tip in dollars?
2. How much was the tip as a percentage of the bill?
Answer:
Because the total is 49.77 and the total is the bill + tip, then the tip is 49.77 - 42 or $7.77. To find the percentage, we just calculate 7.77/42 as a percentage to get 1.11/6 = (111/6)% or 37/2 percent or 18.5%

I need help on having a equations for the bunny and the cat.
Answer:
BUNNY: y = 3x + 5
CAT: y = 1x + 19
Step-by-step explanation:
Answer:
Bunny: 5 + 3y
Cat: 19 + y
Step-by-step explanation:
If we were trying to make an equation about the total number of pounds each animal weighs, we would take the current number of pounds for each animal and then add the product of the pounds they gain and the number of years.
Bunny: 5 + 3y
y - number of years
5 current pounds + 3 additional pounds * y
Cat: 19 + y
y - number of years
19 current pounds + 1 additional pound per year or just 'y'
