Step-by-step explanation:
Radius : 6 ft
Diameter: 12 ft
Area:
circumference :
3/4=0.75
Since 3/4 (of the bar) + 1/4 (of the bar) equals a whole bar (1), and 3/4 (of the bar) + 0.75 equals the whole weight of the bar, 0.75 is 1/4 of the bar. 1/4 times 4 equals 1, and 0.75 times 4 equals 3, so the bar of soap weighs 3 pounds.
The midpoint is given by finding the average x-value and the average y-value, thus the formula would be:
M = ( (x1 + x2)/2, (y1 + y2)/2 ), where (x1, y1) and (x2, y2) are two points on the graph
1. We have two points here, the origin - ie. (0, 0) - and A(18, -6). Thus, using the formula above for the midpoint we get:
M = ( (0 + 18)/2, (0 + (-6))/2 )
M = (18/2, -6/2)
M = (9, -3)
2. Using the same approach, we can find the midpoint for this question using the points J(-9, 5) and K(21, -7):
M = ( (-9 + 21)/2, (5 + (-7))/2 )
M = (12/2, -2/2)
M = (6, -1)
Answer:
-9x=12/-9
Step-by-step explanation:
-4(x+6)=5x+12
-4x-24=5x+12
-9x=12
x=12/-9
