Answer:
The answer is 8 feet.
Step-by-step explanation:
Let x = height where the ladder hits the building
7 squared+x squared=25 squared
49+x squared=625
x squared=576
x=24 feet
Let x = distance from wall:
x^2 + 20^2 = 25^2
x^2 + 400 = 625
x^2 = 225
x = 15 feet
Exact Form:
4/9
Decimal Form:
0.4
Answer:
Step-by-step explanation:
Let x be the added 20% solution.
<u>The salt content is same:</u>
- 50*0.6 + x*0.2 = 0.28*(x + 50)
- 30 + 0.2x = 0.28x + 14
- 0.28x - 0.2x = 30 - 14
- 0.08x = 16
- x = 16/0.08
- x = 200
