Answer:
y = 12
Step-by-step explanation:
set up equation for 'y varies inversely with x': y = k/x
where 'k' is the constant of variation
8 = k/6
therefore, k = 48
value of y when x = 4: y = 48/4; therefore, y = 12
Answer:
the new value is 81.
Step-by-step explanation:
Answer:
3 : 5
Step-by-step explanation:
Since there are 3 boys, the number of girls is 5.
Causing the ratio to be 3 : 5
Sum of interior angles = 180(n - 2)
in this case n = 5 so 180(5-2) = 180(3) = 540
120 + 120 + x + x + x = 540
3x + 240 = 540
3x = 300
x = 100
answer
B) 100
I think that the increase would be $7,452, and the new model would cost $61,452. I may be incorrect though.
