It takes Michelle 25 minutes to descend 850 feet of the beginner slope at Mount Washington. Find her rate of descent (slope). If Michelle begins her descent at a height of 1200 feet, find a linear equation to describe her skiing motion.
Answer:
h = 1200 - 34t
Step-by-step explanation:
25 minutes, descend 850 feet, so each minute, descend 850/25 = 34 feet
after t minutes, descend 34*t feet,
starting at 1200 feet, so the height is h = 1200 - 34t

Choose a different point that lies directly on the graph of the line...
Answer:
Step-by-step explanation:
You got it right: the point (0, -1) is another point on the graph of y = 3x - 1.
Substituting 0 and -1 back into the equation, y = 3x - 1:
-1 = 3(0) - 1
So the pint is also a solution to the equation.
Is a perpendicular bisector the same thing as a median

What is the slope??? Please show step by step!!
Answer:
In order to find the slope, we would need to format the coordinates like rise over run (y/x)
We find two points, (-6, 12) and (-5, 14)
Now we subtract the y coordinates from each other and do the same for the x coordinates
14 and 12 are our y coordinates so that will be our rise
-5 and -6 are x coordinates so that will be our run
14 - 12 2
_______ = ______
-5 - (-6) 1
2 is the slope

A rectangle has a length of X +5 and a width of X -5 and has an area of 15 square units find the length and width of the rectangle.
Answer:L=11.3
W=1.3
Step-by-step explanation:
[tex] \\ [/tex]
To find:-Actual length and width of rectangle[tex] \\ [/tex]
Solution:-So to find actual length and width of rectangle, we need to find value of x.
[tex] \\ [/tex]
we know:-
[tex] \bigstar \boxed{ \rm Area~of \: rectangle = length \times width}[/tex]
[tex] \\ [/tex]
So:-
[tex] \\ [/tex]
[tex] \hookrightarrow \sf Area~of \: rectangle = length \times width \\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15=(x + 5)(x - 5) \\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15=x (x - 5) +5(x - 5)\\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15=x^2 - 5x +5(x - 5)\\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15=x^2 - 5x +5x - 25\\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15=x^2 - \cancel {5x} +\cancel {5x} - 25\\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15=x^2 -0 - 25\\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15=x^2 - 25\\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15 + 25=x^2 \\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15 + 25=x^2 \\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 40=x^2 \\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf x^2 = 40\\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf x = \sqrt{40}\\ [/tex]
[tex] \\ [/tex]

Find the surface area of this shape.
Answer:
54 yds²
Step-by-step explanation:
Area of 1 side: 3*3=9
Number of sides: 6
6*9=54
Answer:
54 square yards
Step-by-step explanation:
This is a cube, as the width, height, and length are all the same. To fine the surface area of a cube, simply find the area of one side and multiply it by six, as a cube has six sides.
[tex]Area = Width*Height\\Area = 3 * 3\\Area = 9[/tex]
The area of one side of the cube is 9 square yards. Therefore, the surface area of the entire cube is 6 x 9 or 54 square yards.

According to the general equation for conditional probability, if P(AnB)= 1/6 and P(B)= 7/24, what is P(A|B)?
Answer:
4/7
Step-by-step explanation:
The conditional probability of A and B happening : P(AnB) is 1/6, and the conditional probability of B happening : P(B) is 7/24, the probability of A happening is 1/6 : 7/24 = 4/7
P(A/B) = Given that B occurs, find the probability of A occuring

josh sells 5 cycles in 2 days. after 20 days, how many cycles should be sold?
Answer:
50 cycles
Step-by-step explanation:
To find this out, we need to know how many cycles he sells a day. So as given he sells 5 cycles in 2 days, so what is half of five? While 2.5 cycles wouldn't make sense, lets use the variable to see what our answer would be approximately.
2.5 cycles x 20 days = 50 cycles.
So, in 20 days Josh would sell 50 cycles.
Answer:
50 cycles will be sold in 20 days
Step-by-step explanation:
2 days⇒5 cycles
1 day⇒5 divided by 2 days
20 days⇒5 cycles multiplied by 20 days divided by 2 days then the final answer is 50 cycles.

Match the graph with the correct set of equations for the linear system. Then, classify the system as Consistent and Dependent, Consistent and Independent, or Inconsistent. (You should have two answers selected)
Answer:
Consistent independent
x + y = 0 and -x + y = -8
Step-by-step explanation:
Inconsistent: parallel lines, no solutions
Consistent dependent: same line, infinite solutions
Consistent independent: intersects at one point, one solution
Therefore, the pair of lines are Consistent independent
From inspection of the diagram:
One line has a negative slope and the other a positive slope.
One has a y-intercept of 0 and the other a y-intercept of -8.
Therefore, the solution is x + y = 0 and -x + y = -8
Because:
x + y = 0 ⇒ y = -x (neg slope, y-intercept of 0)
-x + y = -8 ⇒ y = x - 8 (pos slope, y-interecept at -8)

Trigonometry
Answer:
11. x = 32.6°
12. x = 27.0
Step-by-step explanation:
Question 11
[tex]\sin(\theta)=\dfrac{\textsf{opposite side}}{\textsf{hypotenuse}}[/tex]
Given:
[tex]\theta[/tex] = xside opposite angle = 7hypotenuse = 13[tex]\implies \sin(x)=\dfrac{7}{13}[/tex]
[tex]\implies x=\sin^{-1}\left(\dfrac{7}{13}\right)[/tex]
[tex]\implies x=32.6\textdegree \textsf{ (nearest tenth)}[/tex]
Question 12
[tex]\sin(\theta)=\dfrac{\textsf{opposite side}}{\textsf{hypotenuse}}[/tex]
Given:
[tex]\theta[/tex] = 64°side opposite the angle = xhypotenuse = 30[tex]\implies \sin(64\textdegree)=\dfrac{x}{30}[/tex]
[tex]\implies x=30\sin(64\textdegree)[/tex]
[tex]\implies x=27.0\textsf{ (nearest tenth)}[/tex]

√(11 +4 √7)
hi, brainly helper please solve this ASAP. Thank
Given that: √{11 + 4√(7)}
Let √{11 + 4√(7)} = √(x) + √(y)
Squaring on both sides then
= [√{11 + 4√(7)}]² = {√(x) + √(y)}²
= 11 + 4√(7) = x + y + 2√(xy)
= 11 + 2√(7 * 2²) = x + y + 2√(xy)
= 11 + 2√(7 * 2*2) = x + y + 2√(xy)
= 11 + 2√(7 * 4) = x + y + 2√(xy)
= 11 + 2√(28) = x + y + 2√(xy)
On comparing with both sides, we notice that:
⇛x + y = 11 →→→→Eqn(1)⇛2√(xy) = 2√(28)
⇛ xy = 28
We know that
(x-y)² = (x+y)² - 4xy
(x-y)² = (11)² - 4(28)
(x-y)² = (11*11) - 112
(x-y)² = 121 - 112
(x-y)² = 9
x - y = √(9)
x - y = √(3*3)
Therefore, x - y = 3 →→→→Eqn(2)On adding equation (1) and equation (2), we get
x + y = 11
(+) x - y = 3
_______
2x = 14
Shift the number 2 from LHS to RHS, changing it's sign.
⇛x = 14/2
⇛x = 7/1
Simplify the fraction to get the value of x.
Therefore, x = 7Now, substitute the value of x in equation (1) then
x + y = 11
⇛7 + y = 11
Shift the number 7 from LHS to RHS, changing it's sign.
⇛y = 11 - 7
Therefore, y = 4Now, we have: x = 7 and y = 4
So,
√(x) + √(y) = √(7) + √(4) = √(7) + √(2*2) √(7) + 2
(Or)
Short Method:√{11 + 4√(7)}
= √{11 + 2√(7*4)}
= √{11 + 2√(7)√(4)}
= √[{√(7)²} + {√(4)}² + 2√(7)√(4)
[since, (a+b)² = a² + 2ab + b²]
= √[{√(7) + √(4)}²]
= √(7) + √(4)
= √(7) + √(2*2)
Therefore, √{11 + 4√(7)} = √(7) + 2
Answer: Hence, the simplified form of √{11 + 4√(7)} is √(7) + 2
