Answer:
The question gives you V0 as 220, so plug that in first.
h=-16t2+220t.
Then it says to find the time (solve for t), when the height is 400 ft. Plug 500 ft in as h and solve for t.
500=-16t2+220t.
To solve this, set the quadratic equal to 0 by subtracting 500 from both sides (0=-16t2+220t-500) and use the quadratic formula!

Step-by-step explanation:
The answer is A, seed A is more expensive
X = ?, y = ?;
2 x - 70° = x + 30°
2 x - x = 30° + 70°
x = 100°
x + 30° + 5 y = 180°
130° + 5 y = 180°
5 y = 180° - 130°
5 y = 50°
y = 50° : 5
y = 10°
Answer: C ) x = 100, y = 10
Answer:
Mr. Lawton can make 50 batches of sugar cookies
Step-by-step explanation:
first, we need to convert the 12 pounds to ounces and the conversion rate is 1 pound=16 ounces so 12*16=192+8=200. because each batch needs 4 ounches you divide 200 by 4 to get 50
