Find the slope of the line connecting (1990,435000) and (2005,482300):
482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr
Use the point-slope formula to find the equation of this str. line:
y-435000 = (3153/yr)(x-1990)
The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is
given by y-435000 = 3153(30) = 94590, so that y = 529590.
Since the ratio is part-Whole, first you need to find the whole. If you add all of the marble colors together (17+13+23) you get the total marbles (53) in the box. The ratio of red marbles to the total would be 17 to 53.
Answer:
the value of x = 56
Step-by-step explanation:
if both are similar figures, then ratio of their
sides will be constant , so
=》14 / 17 = x / 68
=》14 / 17 × 68 = x
=》14 × 4 = x
=》x = 56
hence, value of x = 56.
i hope you got it.
