Answer:
-12
Step-by-step explanation:
"+" means positive and addition while "-" has the opposite meaning. The baker discarding (throwing away) the bread means the amount of bread he has decreases. So we use negative to represent this situation.
Cookies baked = 12 × 3 (number of trays) = 36
Bags = 4
In 4 bags = 36 cookies
in 1 bag = 36/4 = 9 cookies (divide both sides by 4)
SO 9 COOKIES WERE PLACED IN EACH BAG

Answer:
(0.4, -57.9)
Step-by-step explanation:
y = 3x³ + 12x² - 10x - 56
dy/dx = 9x² + 24x - 10 = 0
x = [-24 +/- sqrt(24² - 4(9)(-10))]/(2×9)
x = -3.033006505, 0.3663398379
d²y/dx² = 18x + 24
For minima, d²y/dx² > 0 which is at x = 0.3663398379
y = 3(0.3663398379)³ + 12(0.3663398379)² - 10(0.3663398379) - 56
y = -57.90544608

Answer:
The number of baseball card to begin with is 143
Step-by-step explanation:
Let The number of baseball cards = x
The number of sold baseball card = 60% of x
= 0.6 x
The number of left baseball card = x - 0.6 x = 0.4 x
The number of card gave away = 30 % of left cards
= 0.3 × 0.4 x = 0.12 x
The number of card left in his possession = 40
So, 0.6 x + 0.12 x + 40 = x
Or, 40 = x - 0.6 x - 0.12 x
Or, 40 = 0.28 x
∴ x = = 142.85 ≈ 143
Hence The number of baseball card to begin with is 143 Answer
