Answer:
A: 66/21
E: 22/7
Step-by-step explanation:
The offered choices reduce to 3 1/7 or to 3. The best approximations of those given are the ones that reduce to 3 1/7.
A: 66/21 = 22/7 = 3 1/7
B: 60/20 = 3
C: 21/7 = 3
D: 45/15 = 3
E: 22/7 = 3 1/7
___
Comment on pi approximations
The ratio 22/7 differs from π by about 0.04%. A better approximation is 355/113, which differs from π by about 0.000008%. The approximation 3.14 differs from π by about 0.05%.

What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
The position of Allien in the coordinate plane is (0,5), the coordinate of the rocket is (5,0). The slope between the two is,
Slope, m = (0 - 5)/(5 - 0) = -5/5 = -1
The equation of the line can be written as,
y = -1x + C
substitute any one of the point in the equation,
0 = -1(5) + C
0 = -5 + C
C = 5
Hence, the equation of the line is Y=-x+5. Thus, the correct option is C.

If the snow is falling at a rate of 1 2/3 inches per hour, how many hours will it take to snow 12 inches?
Answer:
It'll take 7.2 hours
Step-by-step explanation:
(5/3)in 12in
--------- x --------
1 hr x hr
Cross multiply and you get
(5/3)x = 12
Then you divide 12 by (5/3) and you get that x = 7.2 hrs
Answer:
7.2 hours
Step-by-step explanation:
1 2/3 inches per hour = 5/3 inches per hour
12 inches = 36/3 inches

Create and solve a quadratic equation that has 1 real solution
Answer:
x^2 - 4x + 4 = 0
x = 2
Step-by-step explanation:
(x - 2)(x - 2) = 0
x^2 - 2x - 2x + 4 = 0
x^2 - 4x + 4 = 0
The equation is:
x^2 - 4x + 4 = 0
It is a quadratic equation because of the x^2 term.
Now we solve it by factoring.
x^2 - 4x + 4 = 0
(x - 2)(x - 2) = 0
x - 2 = 0 or x - 2 = 0
x = 2 or x = 2
The only solution is x = 2.

Answer:
equation: 3x - 2 + 4x - 9 + 3x - 9 = 180x = 20Step-by-step explanation:
add all internal angles
∠H + ∠I + ∠J = 180
where:
∠H = 3x - 2
∠I = 4x - 9
∠J = 3x - 9
plugin the values into the ∠H + ∠I + ∠J = 180 formula:
equation: 3x - 2 + 4x - 9 + 3x - 9 = 180
combine similar terms: 3x + 3x + 4x = 180 + 2 + 9 + 9
simplify: 10x = 200
divide 10 both sides: x = 20
