Answer:
The speed is 20.8 m/s
Step-by-step explanation:
If a projectile ascends vertically, and after 3 seconds it reaches its maximum height, calculate the velocity that it carries to the middle of its downward trajectory
Let the maximum height is h and initial velocity is u.
From first equation of motion
v = u + at
0 = u - g x 3
u = 3 g.....(1)
Use third equation of motion
Let the speed at half the height is v'.
Answer:
For packages of 8 =
Each package of Buns contain 8 pieces.
Therefore 100 barbecue will be contained in 100/8 = 12.5 packages
For packages of 12 =
Each package of Buns contain 12 pieces.
Therefore 100 barbecue will be contained in 100/12 = 8.3 packages

For the first question, you will write a ratio of 1/2 oz:10 pounds. Please see the attached picture. There are 9 groups of 10 oz in 90 oz, so you will need 9 groups of the amount of medicine too!
For the second question, you need to understand that the exponent (2^3) must be evaluated first because all forms of multiplication/ groupings comes first before adding or subtracting.
Exponents are a way of showing repeated multiplication, so it is done first.
