Answer:
40 students picked bananas
Step-by-step explanation:
3/4 picked apples
1 - 3/4 = 1/4 picked bananas
3/4x = 120
Multiply both sides of the equation by 4/3
4/3 * (3/4x) = 120/1 * (4/3)
x = 480/3
x = 160
Total of 160 students
/ \
120 = apples 160 - 120 = 40 = bananas
40 students picked bananas

Unfortunately, there is no given table. However, assuming no air resistance, the projectile moves in constant acceleration in the y-axis, while constant velocity in the x-axis. If the total time of flight is 6 seconds, then at 3 seconds the reaches its maximum height. Also, there is no given initial velocity, which means any useful calculation is impossible.
Answer:
If there isn't an exact number in the middle you take the two numbers that are in the "middle" add them together and divide by 2

Answer:
We have 5% and 25% solutions and we need 300 ml of 10%.
Setting up 2 equations:
A) x + y = 300
B) .05 x + .25 y = (.10 * 300) Multiplying A) by -.25
A) -.25x -.25y = -75 Then adding this to B) we get
-.20 x = -45
x = 225 ml .05% and we use 75 ml of 25%
