Answer:
D., x= 19.7 or ≈20. g
Step-by-step explanation:
P(x) = [100(15+x)]/(100+x)
When 0 g additional salt is added, x=0. we have
P(0) = [100(15+0)]/(100+0)= 15
x=0, P=15
We can see this point only on the graph D.
P(x) =29 = [100(15+x)]/(100+x)
29 = [100(15+x)]/(100+x)
29(100+x) = 100(15+x)
2900+29x = 1500+100x
2900-1500=100x-29x
1400 = 71x
x ≈ 19.7 g or ≈20. g
From the graph D, we can see that to get 29% we need to add ≈ 20 g of salt.
Answer:
The elevation of Mt. Wilson is 16,160.10 ft
Step-by-step explanation:
Let
x-----> represent the elevation of Mt. Wilson
y ----> represent the elevation of Snow Crest
we know that
y=x+11,990.21 ----> linear equation that represent this situation
we have that
y=28,150.31 ft ----> see the attached figure
substitute in the linear equation and solve for x
28,150.31=x+11,990.21
x=28,150.31-11,990.21=16,160.10 ft
