An airplane flew 4 hours with a 25 mph tail wind. The return trip against the same wind took 5 hours. Find the speed of the airplane in still air. This similar to the current problem as you have to consider the 25 mph tailwind and headwind. Plane on outbound trip of 4 hours with 25 mph tailwind and return trip of 5 hours with 25 mph headwind Let r = the rate or speed of the airplane in still air. Let d = the distance a. Write a system of equations for the airplane. One equation will be for the outbound trip with tailwind of 25 mph. The second equation will be for the return trip with headwind of 25 mph. b. Solve the system of equations for the speed of the airplane in still air.

P(A and B) = 0.1
Answers
The probability of event A and event B will be 0.10. Then the correct option is A.
What is probability?
Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
In an experiment, the probability that event A occurs is 0.2 and the probability that event B occurs is 0.5.
If A and B are independent events. Then the probability is given as,
P(A and B) = P(A) x P(B)
P(A and B) = 0.2 x 0.5
P(A and B) = 0.10
The probability of event A and event B will be 0.10. Then the correct option is A.

Step-by-step explanation:
(14x3y2z)4
Answers
Final answer:
The result of raising the polynomial (14x3y2z) to the 4th power is 38416x12y8z4. This is calculated by individually multiplying each part of the polynomial by itself 4 times.
Explanation:
The problem is asking you to calculate the result of raising a polynomial (14x3y2z) to the 4th power.
The operation refers to using the rule of powers which states that any base with an exponent is multiplied by itself the amount of times indicated by the exponent. The result should therefore be calculated as follows:
(14x3y2z)4 = 38416x12y8z4
To find the answer, we raised each part of the polynomial to the 4th power. 144 equals 38416, (x3)4 results in x12 because you multiply the exponents, (y2)4 results in y8 for the same reason and z4 because anything to the power of 4 is itself raised 4 times.

Answer:
Volume of a right circular cylinder is given by:
.....[1] where
V represents the volume of a cylinder.
r represents the radius of a cylinder.
h represents the height of a cylinder.
As per the given statement:
Diameter(D) = 19.6 yd and height(h) = 23.52 yd.
Diameter = 2r where r is the radius of the cylinder.
Substitute these given values in [1] we have;
cubic yard
Simplify:
V = 7,092.82291 cubic yard.
Therefore, volume of a circular cylinder to the nearest hundredths is, 7092.82 cubic yard.
Answer: 7092.82
