Call Canada's population
, and call the U.S. population
.
We see that
. Substituting 32 million for c, we see that
. Multiplying by ten, we see that
. By using Algebra properly, we have ensured that the number of zeroes in our final answer is correct.
Answer:
7x - 4
Step-by-step explanation:
2x + 4 + 5x - 8
7x + 4 - 8
7x - 4
Answer:
35 degrees
Step-by-step explanation:
The angle is given to be a right angle by the red square. The right angle is intercepted by a line. One side of the whole 90 degree angle is said to be 55 degrees. Both sides should equal 90 degrees if added.
This means that to find the missing angle, you would subtract 55 degrees from 90 degrees to get 25 degrees.
The formula for a falling object is
v = u +gt
where
u = initial velocity (=0 for a falling object)
g = acceleration due to gravity, 32.2 ft/s²
t = time, s
In terms of distance fallen,
v² = u² + 2gh
where h = distance fallen, ft.
Because h = 23 ft and u = 0, therefore
v² = 2*32.2*23 = 1481.2
v = 38.486 ft/s
Answer: 28.49 ft/s (nearest hundredth)
