Answer:
9,000 minutes (150 hours)
Step-by-step explanation:
You have 3,600 points total; you need to divide it by 2 points.
3,600 ÷ 2 = 1,800
So, now you need to multiply the 1,800 points by 5 minutes.
1,800 × 5 = 9,000
Another way:
You can figure out how long it takes to get 1 point. If 2 points takes 5 minutes, divide 5 by 2.
5 ÷ 2 = 2.5
Now you need to figure out how long it would take to get 3,600 points. If each point takes 2.5 minutes, just multiply.
3,600 × 2.5 = 9,000
It would take 9,000 minutes (which is equivalent to 150 hours) to get to 3,600 points.
can someone please help meee
Answer:
Step-by-step explanation:
Ok so you are given the values of the slope-intercept form with m being the slope and b being the y-intercept. So since b is equal to -1 you want to plot a point at (0, -1) since that is the y-intercept (when x = 0). The next thing you want to do is look at the slope, which is essentially saying each time x increases by 5 the y-value decreases by 4 or in other words rise/run which is negative which is why you're going down. So from the point (0, -1) go forward 5 units and go down 4 units which should lead you to (5, -5) and the third point you can plot is by going backwards instead of forwards. So instead of every time x increases by 5 y decreases by 4 you're going to do the inverse. Every time x decreases by 5, y is going to increase by 4. So by doing this from the y-intercept (0, -1) you should go backwards 5 units and up 4 units which should lead you to (-5, 3). And then now just draw a line that goes through all those three points. Hope that helps :)

find the value of x
Answer:
x=5
\
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
Line segment UV and line segment VW together form line segment UW.
UV + VW = UW
(5 + x) + (6) = (2x + 11)
5 + x + 6 = 2x + 11
x + 11 = 2x + 11
x + 11 - 11 = 2x + 11 - 11
x = 2x
x - x = 2x - x
0 = x
You can also verify the result by substituting x with our result 0.
5 + x + 6 = 2x + 11
5 + (0) + 6 = 2(0) + 11
11 + 0 = 0 + 11
11 = 11
Left side of the equation is the same as the right side of the equation, therefore the result x = 0 is correct.

The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The height of the triangle is 6.2172 cm.
What is Sine (Sinθ)?The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,
Sin(θ) = Perpendicular/Hypotenuse
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The hypotenuse is the longest side of the triangle.
In the given diagram let the centre of the circle be represented by O, while the point at which line segment h and the circle intersect be represented by B. Also, the point at which the 90° angle is formed is represented by A.
Now, in the ΔABO, for the ∠AOB, the sine ratio of the trigonometric function can be written as,
sin(θ) = perpendicular / Hypotenuse
sin(51°) = AB / OB
sin(51°) = h/ 8 cm
8cm × sin(51°) = h
h = 6.2172 cm
Hence, the height of the triangle is 6.2172 cm.

Simultaneous equation find x and y
Answer:
x = 27, y = 6
Step-by-step explanation:
x - 2y = 15
x - 4y = 3 (rearranged the orginal equation)
x - 2y = 15
- x - 4y = 3
___________
2y = 12
y = 6
Plug this value in any original equation
x - 2(6) = 15
x = 27
x and y of the simultaneous equation are 27 and 6 respectively.
Given,
x - 2y = 15
x - 3 = 4y
Here,
Equations:
x - 2y = 15
Rearranged the original equation
x - 4y = 3
Now subtract both equations,
x - 2y = 15
x - 4y = 3
⇒2y = 12
y = 6
Plug this value in any original equation
x - 2(6) = 15
x = 27
Thus the solution of system of equation is x = 27 and y = 6.

The graph of the function:
[tex]f(x) = \sqrt{x + 2} - 3[/tex]
Is the last graph (bottom graph of the second image).
Which graph represents the given function?
Here we have the function:
[tex]f(x) = \sqrt{x + 2} - 3[/tex]
Remember that the argument of a square root must be zero or larger, then the minimum of the domain is the value of x such that:
x + 2 = 0
x = -2
Then the function starts at:
[tex]f(-2) = \sqrt{-2 + 2} - 3 = -3[/tex]
Then the graph should start at (-3, 2).
We can also identify another point by evaluating in x = 2.
[tex]f(2) = \sqrt{2 + 2} - 3 =2 - 3 = -1[/tex]
So the function also passes through (2, - 1).
Notice that the only graph that contains these two points is the last graph (the bottom graph on the second image), so that is the correct option.

Round your answer to the nearest tenth of a foot if necessary.
Trigonometry: Rounded to the nearest tenth of a foot, the answer is 15.2 feet.
What is trigonometry?Trigonometry is a branch of mathematics that studies the relationships between side lengths and angles of triangles. It is used to calculate unknown side lengths and angles of triangles when given other values, and to solve various problems in different fields such as engineering, navigation, astronomy, and physics.
The horizontal distance between the base of the ladder and the wall can be calculated using trigonometry.
The formula for finding the opposite side of a triangle (in this case, the horizontal distance) when given the angle and the adjacent side is: opposite side = adjacent side x tan (angle)
Therefore, the horizontal distance is 16 feet x tan(66°) = 15.2 feet.
Rounded to the nearest tenth of a foot, the answer is 15.2 feet.
