Answer:
2*10 ^6 shoes in 10 years
Step-by-step explanation:
1.81 × 10^4 pairs of shoes each month
1.2 × 10^2 months in 10 years
Multiply these together to determine the number of shoes in 10 years
1.81 × 10^4 * 1.2 × 10^2
We want to estimate so 1.81 is approximately 2 and 1.2 is approximately 1
2 × 10^4 * 1 × 10^2
Multiply the numbers
2*1 = 2
Add the exponent
10 ^ ( 4+2)
10 ^6
Put this back together
2*10 ^6
4.509 is greater that 4.508 and less than 4.512
Answer:
it is y = 2x + 3
Step-by-step explanation:
i just took the test
Velocity with wind = 1,980 / 4.5 = 440 mph
Velocity against wind =1,980 / 5.5 = 360 mph
Plane in still air - wind speed = 360
Plane in still air + wind speed =440
Adding both equations:
2*Plane in still air = 800
Plane in still air = 400 mph
Plane in still air + wind speed =440
Therefore, wind speed = 40 mph
Answer:
2.04
Step-by-step explanation:
The GDP of USA IN 2008 = $14.72 trillion
The GDP of USA IN 2009 = $14.42 trillion
Change in GDP
$14.72 trillion- $14.42 trillion = $0.3 trillion
Percentage Change
($0.3 trillion/$14.72 trillion) x 100%
0.02038 X 100% = 2.038=2.04 approximately
