Answer:
The average rate on the outgoing trip is 30 miles per hour.
Step-by-step explanation:
Consider the provided information.
You commute to work a distance of 40 miles and return on the same route at the end of the day.
Your average rate on the return trip is 30 miles per hour faster than your average rate on the outgoing trip. If the round trip takes 2 hours.
Let the average rate on the outgoing trip is x
Average rate on the return trip = x+30
As we know 
The value of x can't be a negative number so x=30
Hence, the average rate on the outgoing trip is 30 miles per hour.
Bear in mind that, (-9) and -9 are very different mammals, we're assuming, you meant (-9)⁻¹.
The answer is 320.
If 16 = x / 20, then x = 320
Multiply both sides of the equation by 20:
20 * 16 = 20 * x / 20
Multiply the terms on the left side of the equation:
320 = 20x/20
320 = 20/20 * x
Simplify the rigth side of the equation:
320 = 1 * x
320 = x
Therefore, x = 320
Answer:
135°
Step-by-step explanation:
Using S = rA, where S is arc length, r is radius and A is angle(in radians).
Comparing:
=> 12 = 16A
=> 12/16 = A
=> 3/4 = A
Required radian is 3/4 which is 3/4 * 180° = 135°
3,000x10=30,000
