Answer:
59%
Step-by-step explanation:
simply, it would be 11+2/22 = 59%
I assume there are no student that passed 0 tests
Answer: $24.50
Post office:£1 = $1.27
£350 = $1.27 × 350 = $444.50
Bank:£1 = $1.34
£350 = $1.34 × 350 = $469
Therefore, the difference will be:
= $469 - $444.50
= $24.50
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.
