Answer:
18.1 m
Step-by-step explanation:
For this problem, we will simply use the initial height of 0 meters, the height of 25 meters after 2 minutes, the decline of 2.2 meters every minute for 7 minutes, and a final increase of 8.5 meters to find the final altitude of the ballon.
0m + 25m - 2.2m(7) + 8.5m = ?
25m - 15.4m + 8.5m = ?
9.6m + 8.5m = ?
18.1m = ?
Hence, the final altitude of the ballon is 18.1m.
Cheers.
Answer: The value of b = 0.99
The probability that a day requires more water than is stored in city reservoirs is 0.161.
Step-by-step explanation:
Given : Water use in the summer is normally distributed with

Standard deviation : 
Let x be the combined storage capacity requires by the reservoir on a random day.
Z-score : 

The probability that a day requires more water than is stored in city reservoirs is :
Hence, the probability that a day requires more water than is stored in city reservoirs is 0.161

Answer:
c = -7/9p
Step-by-step explanation:
8p + 9c = p
8p − 8p + 9c = p − 8p
Step 2:
9c = −7p
Step 3:
9c/9 = -7p/9
c = -7/9p

Answer:
(C) Perpendicular bisector theorem
Step-by-step explanation:
(A) Right angle theorem : The right angle theorem states that if two angles are supplementary and congruent, then these two angles are right angles.
(B) Converse of perpendicular bisector theorem: The converse of perpendicular bisector theorem states that If a point is equidistant from the endpoints of a segment, then it is on the perpendicular bisector of that segment.
(C) Perpendicular Bisector Theorem: The Perpendicular Bisector Theorem states that If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.
(D) Pythagorean theorem: The Pythagorean theorem states that in the right angled triangle, the square of the hypotenuse of the triangle is equal to the sum of the squares of the other two sides that is:

Since, the given statement is the statement of the Perpendicular bisector theorem, thus option C is correct.
