Pi (Ratio of the Circumference of a Circle to Its Diameter) Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Solve the simultaneous equations
4x + 5y = 9
4x - 2y = 2
Answer:
x = 1 and y = 1
Step-by-step explanation:
Let's solve your system by substitution.
4x + 5y = 9 ; 4x − 2y = 2
- Solve 4x + 5y = 9 for x:
4x + 5y = 9
4x + 5y + − 5y = 9 + − 5y (Add -5y to both sides)
4x = − 5y + 9
[tex]\frac{4}{x} = \frac{- 5y + 9}{4}[/tex]
[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]
Then Substitute [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex] for x in 4x - 2y = 2
4x − 2y = 2
4([tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]) − 2y = 2
− 7y + 9 = 2 (Simplify both sides of the equation)
− 7y + 9 + − 9 = 2 + − 9 (Add -9 to both sides)
− 7y = − 7
[tex]\frac{- 7y}{- 7} = \frac{- 7}{- 7}[/tex] (Divide both sides by -7)
y = 1
Substitute 1 for y in x = [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]
[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]
[tex]x = \frac{- 5}{4} (1) + \frac{9}{4}[/tex]
x = 1
So, x = 1 and y = 1

x-6/9=-5
Answer:
x = -13/3
Step-by-step explanation:
Given: x-6/9 = -5
You want to isolate the variable (x).
To make this easier, turn -5 into -45/9 (common denominator w/ -6/9)
Then, add -6/9 to -45/9.
x = -39/9
Simplify.
x = -13/3

Step-by-step explanation:
In hockey, Ed makes 7 goals for every 10 shots. If he takes 6 shots, what is the probability that he will make at least 5 goals?
================================================================
Explanation:
Let's consider the case where Ed makes all 6 shots. The probability of this happening is (7/10)^6 = 0.117649
Let A = 0.117649 so we can use it later.
----------------
Now consider the case where Ed makes exactly 5 shots. So he misses exactly 1 shot. Furthermore, consider the case where his first shot is a miss and the remaining 5 shots are successful.
The probability of getting the first shot a miss and the remaining 5 successful is (3/10)*(7/10)^5 = 0.050421
Note how 3/10 and 7/10 add to 1. The 3/10 is the probability of getting a miss (since he makes 7 goals for every 10 shots, he misses those 3 goals).
The value 0.050421 represents the probability for that first shot being a failed attempt while the rest are successful shots. Since there are 6 slots total, this means 6*0.050421 = 0.302526 represents the probability of missing exactly one goal and hitting the others. By this point, we aren't making the failed attempt at slot 1. It could be at any slot. For instance, the failed attempt could be at slot 4.
In other words, 0.302526 is the probability of making exactly 5 shots.
Let B = 0.302526
----------------
To recap,
A = probability of getting all 6 shots in the goal (no failed attempts).B = probability of getting exactly 5 shots in the goal (exactly one attempt failed).These two events are mutually exclusive. They cannot happen at the same time. That allows us to add the values of A and B to get the final answer
A+B = 0.117649+0.302526 = 0.420175
Therefore, A+B = 0.420175 represents the probability of either getting all 6 shots in the goal OR getting exactly five shots in the goal.
In short, 0.420175 represents the probability of making at least 5 shots. The phrasing "at least 5" means "5 or more".
-----------------
If you wanted to calculate this in one line, then you could say
(7/10)^6 + 6*(3/10)*(7/10)^5 = 0.420175
This decimal value is exact.
PLEASE HELP!!!!!! PLEASE WILL MARK BRAIN FOR FIRST AND RIGHT ANSWER!!!
Answer:
yes
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
All you need to do is solve for x and y because the intersection of both lines will only have one intersection.
since both equations are equal to y then you can set them equal to each other:
7x+8=x+1
6x=-7
x=-7/6
then inset back into y=x+1
y=-7/6+1
y=1/6
so that is the only point of intersection of the lines and it cannot be (3,8)

what is the equation of the line?
Answer:
x=3
Step-by-step explanation:
the x axis is going across by 2 and the number in between 2 and 4 is 3 and the line is going through the x axis hence the equation of the line is x=3
Answer:
[tex]x=3[/tex]
Step-by-step explanation:
Normally, linear equations would be written in slope-intercept form, [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis). However, linear equations for horizontal or vertical lines are organized differently.
Here, we're given a vertical line. Vertical lines are written like [tex]x=d[/tex], where [tex]d[/tex] is the x-intercept, or the value of x when the line crosses the x-axis.
From the graph, we can tell that the x-intercept is 3. Therefore, our equation would be [tex]x=3[/tex].
I hope this helps!
Answer for 2y + 4/x = 10
Answer:
Y = 5 - 2/x
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
You want to isolate x so first, you have to multiply the whole equation by 1/4 so it will look like 1/4(2y+4/x=10). Simplify this to get 1/2y+x=5/2. You want to isolate x, so you have to subtract 1/2 from each side, this will make the equation x=5/2-1/2. Simplify this to get x=4/2 which can also be simplified to x=2. Therefore, the answer is x=2

About % of the freshman class are left-handed.
Answer:
About 13% of the freshman class are left-handed
Step-by-step explanation:
To find the percentage of a whole you need to divide the part by the whole number (85/645 = 0.1316), then you round to the nearest tenth (0.13) and change it into a percentage by moving the decimal point 2 numbers to the right. (13%)
