Part A: It will take her 8 hours to pick 72 pounds of strawberries (9/72=8)
Part B: $192. (8*2=16*12=192)
Answer: -4x+2y=12
Step-by-step explanation:All you have to do is multiply the variables one after the other taking note of the sign
4,000,000,39
there you go!
Answer: 5 seconds
<u>Step-by-step explanation:</u>
Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).
h(x) = -2x² + 20x + 48
a=-2 b=20 c=48
Axis of symmetry: x = 
= 
= 
= 5
You have 8 people, you have 2 groups of 4.
8!/4!4!
=(8*7*6*5*4*3*2)/(4*3*2*4*3*2)
=(8*7*6*5)/(4*3*2)
=7*6*5/3
=7*2*5
=70
It's been a few years since I've done this. If you haven't learned how to do this type of an equation yet, then I'm probably wrong.
