Answer:
it would take it 2 hours to make 600 donuts, it makes 5 donuts a minutes
Step-by-step explanation:
Simple math.
3000/10=300 which means 300 donut per hour.
300 x 2 = 600.
300 / 60 = 5.
Answer:
Step-by-step explanation:
Given equation is 
Factor denominators then solve by making denominators equal
take squar root of both sides
Hence final answer is .
Answer:
7r³ - 3r² + 20r
Step-by-step explanation:
(9r³ + 5r² + 11r) + (-2r³ + 9r - 8r²)
You can get rid of the parentheses since there is nothing to distribute.
9r³ + 5r² + 11r - 2r³ + 9r - 8r²
Combine like factors.
7r³ - 3r² + 20r
Answer: (0.18,0.26)

Answer:
8
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 4, 6 ), thus
y = a(x + 4)² + 6
To find a substitute (- 3, 14) into the equation
14 = a(- 3 + 4)² + 6 ( subtract 6 from both sides )
8 = a
Thus the coefficient of the x² term is a = 8
