By Pythagoras Theorem,
Height of Triangle = (1.7^2-1^2)^0.5 = (1.89)^0.5= 1.37 in
Area of one triangle = 1.374772708* 2*0.5= 1.374772708in^2
area of polygon = 5*1.374772708in^2=6.87in^2 = 6.9in^2
answer is b
75x+2=
75x-2=-2. move the 2 to the other side
75x=-2 now divide 75 both sides
75/75x=-2/75
x=-2/75
3/n and 6/n I hope it helped
Direct variation is y = kx
Inverse variation is y = k/y
if z varies directly with x, then the equation would be z = kx
if z varies inversely with y^2 then the equation would be z = k/y^2. Combining, these two, we have z = kx/y^2
We use the first set of values to find the constant k:
x = 2, y = 5, z = 8:
8 = 2x/25, k = 100. Now we use the second set of values to find z:
x = 4, y = 9, k = 100 and z is unknown:
z = (4X100)/9^2
z = 400/81--> this is your final final answer.
