Answer:
33 1/3 lb
Step-by-step explanation:
When the distance between them goes from 8 ft to 12 ft, it is 1.5 times what it was. Then the force will be multiplied by the inverse of the square of this:
(75 lb)×1/(1.5²) = 75/2.25 lb = 33 1/3 lb
At 12 feet apart, the attraction force is 33 1/3 pounds.
Y = mx
We just need to find the slope:
y2 - y1 / x2 -x1 = -4 - 4 / 1 - - 1 = -8/2 = -4/1 = -4
so: y = -4x
Hope that helps! :)
Answer:

Step-by-step explanation:
Answer:
1. 80
2. 20
3. 1080
Step-by-step explanation:
1. area= 1/2 x base x height
1/2 x 8 x 20= 80
2. first you find the rectangle which is 5x6=30
then the triangle base is 14-6=8
1/2x8x5=20
3. 12x15x6=1080
Rectangle:
A = BH
= (18)(4)
= 72
Finding area of square:
72 = 2x
/2 /2
36 = x
Finding perimeter of square using area:
P = √a * 4
= √36 * 4
= 6 * 4
= 24
Therefore the perimeter of the square is 24 inches. I am not sure so sorry for any mistakes.
