Answer:
Over a 22 seconds, the altitude will be: 924 feet
Step-by-step explanation:
- Let 'x' be the time in seconds
As the altitude of an airplane is decreasing at a rate of 42 ft per second.
Thus, the expression to find the altitude at x seconds is:
y = 42x
so at x = 1 sec, y = 42 feet
Now, putting x = 22 seconds to determine the altitude at 22 seconds
y = 42x
= 42(22)
= 924 feet
Thus, over a 22 seconds, the altitude will be: 924 feet
Supplementary angles have sum = 180
m<TUW = 31
m<TUV = 180 - 31 = 149
answer is 149 (last choice)

answer is vertical angles (2nd choice)
Answer:
Step-by-step explanation:
The sum of two perfect cubes breaks down into two factors, the first is the sum of their cube roots, and the second is made up of the square of the first root minus the product of both roots plus the square of the second root.
The difference of two perfect cubes is decomposed into two factors, the first is the difference of their cube roots, and the second is made up of the square of the first root plus the product of both roots plus the square of the second root.

Answer:
32
Step-by-step explanation:
2(2.5z − 58 + 43) = 176− 46
5z - 116 + 86 = 130
5z -30 = 130
5z = 160
z = 160/5
z = 32
