1. A = (1/2)bh = (1/2) * 30 ft * 12 ft = 180 ft^2
2. 21/25 * 100 = 84%
3. $13.26/(3 boxes) = $4.42/box
Answer:
see below
Step-by-step explanation:
Number of workers (x) 0 10 20 30 40 50 60 70 80 90
Number of units (y) 2 52 102 152 202 252 302 352 402 452
Part A
There is a correlation
For each increase of 10 in x, there is an increase of 50 in y
10 10 10 10 10 10 10 10 10
Number of workers (x) 0 10 20 30 40 50 60 70 80 90
Number of units (y) 2 52 102 152 202 252 302 352 402 452
50 50 50 50 50 50 50 50 50
Part B
m = (y2-y1)/(x2-x1)
= (452-402) /( 90-80) = 50/10 = 5
The y intercept is the value of y when x =0
The y intercept is 2
The slope intercept form of the the line is
y = mx+b
y = 5x+2
PartC
The y intercept is that we start with 2 of the units and for each worker gained, they will make 5 units per day
Answer:
75%
Step-by-step explanation:
57 / (57+19) = 0.75
A south pole of one magnet can approach the north pole of another. The magnetic fields are aligned. This makes an attractive force between the two magnets. The farther apart they are, the higher their potential energy.
hope this helped :)
