Area of the figure:
Af = a² + 2 a²/4 π = 2.57 a²
Area of the shaded region:
As = 2 a²/4 π = 1.57 a²
x = (1.57 · 100) / 2.57 = 61 % ≈ 60 %
Answer: B) about 60 %
Answer:
y=3x+12
y-12=3x
x=y/3 - 4
f(y)=y/3 - 4
or
f(x)=x/3 - 4
where f(x) is the inverse of y.
Hope this helps ;]
Step-by-step explanation:
In a direct variation relationship the values must satisfy that y = kx. This si y is always a constant value (k) times x.
So, you can find multiple values that meet this:
y = kx => k = y / x = 11 / 18
=> y = (11/18)x
Now you can give any value to x and fint the value of x that satisfy the relationship:
x y = (11/18)x
1 11/18
2 11/18 * 2 = 11/9
18 11/18 * 18 = 11
36 11/18 * 36 = 22
So, there you have several additional values for x and y in the same relationship that y = 11 and x = 18, and you can find many more using the same rule: y = (11/18)*x
Answer:
We have a1 = 27 and r = 3 (because 27:9 = 3; 9:3 = 3; 3:3 = 1);
Then s = 27 / (1 - 3) ;
Finally, s = - 27 / 2;

Answer:
0.6 x 94, 60/100 x 94
Step-by-step explanation:
0.6 = 60% of 1.
60/100 also = 60% of 1
