To find the answer, we plug 8 into the equation in the place of x, since x represents the number of minutes.
w(8) = 250(8)
2(8) = 2000
You can read 2000 words in 8 minutes.
Answer:
(fºg)(x) = x -2
Step-by-step explanation:
f(x) = x + 2
g(x) = x - 4
(fºg)(x) = ( x - 4) + 2
(fºg)(x) = x -2

Started out with 32/32. They ate 18/32, 32-18=14; 14/32. To simplify, 7/16 was left.
The answer is 3.14 m
The area (A) of the circle with radius r is: A = π · r²
The area of the quarter of the circle is: A1 = 1/4A = 1/4 · π · r²
We have:
A1 = ?
r = ?
π = 3.14
d = 4 m
A diameter d is the twice of the radius r: d = 2r.
Therefore, the radius is the half of the diameter: r = d/2
So, the area of the quarter circle would be:
A1 = 1/4 · π · r² = 1/4 · π · (d/2)² =1/4 · π · d²/2² = 1/4 · π · d²/4 = 1/16 · π · d²
A1 = 1/16 · π · d² = 1/16 · 3.14 · 4² = 1/16 · 3.14 · 16 = 3.14 m
