Answer:
AH = 1 or 4
CH = 4 or 1
Step-by-step explanation:
An altitude divides a right triangle into similar triangles. That means the sides are in proportion, so ...
AH/BH = BH/CH
AH·CH = BH²
The problem statement tells us AH + CH = AC = 5, so we can write
AH·(5 -AH) = BH²
AH·(5 -AH) = 2² = 4
This gives us the quadratic ...
AH² -5AH +4 = 0 . . . . in standard form
(AH -4)(AH -1) = 0 . . . . factored
This equation has solutions AH = 1 or 4, the values of AH that make the factors be zero. Then CH = 5-AH = 4 or 1.
Answer:
Both sides are equal, true for all 'b'
Step-by-step explanation:
Add similar elements: b + 0.17b = 1.17b
1.17b = 1.17b
Multiply both sides by 100
1.17b * 100 = 1.17b * 100
Refine
117b = 177b
Subtract 117b from both sides
117b - 117b = 117b - 117b
Refine
0 = 0
Both sides are equal, true for all 'b'

2.2 gallons of water flow every minute. To figure out how much water flows from a shower in 9 minutes, just multiply 9 × 2.2 which equates to 19.8.
If 5 people shower for 9 minutes, just multiply 19.8 × 5 which equates to 99 gallons of water.
