Answer:
.
Step-by-step explanation:
We need to write an equation for the amount of chemical B as a function of the amount of chemical A.


...(1)
where, k is constant of proportionality.
It is given that fifteen grams of chemical A is used to produce 3 grams of chemical B. It means a=15 and b=3.
Substitute a=15 and b=3 in (1).


Substitute
in (1).

Therefore, the required function is
.
First of all, you must change 40% into a decimal by multiplying by 100⇒.40
Then you divide 55 by .40
55÷.40=137.5
Therefore, 55 is 40% of 137.5
Answer: He will have $1721.28. after 4 years.
Step-by-step explanation:
The formula we use to find the compounded amount A is :
, where P= principal value, r = rate of interest , t= time.
As per given , we have
P=$1500 , r=3.5%=0.035 , t= 4 years
Money he will have after 4 years = 

Hence, he will have $1721.28. after 4 years.
Answer: The missing value, y = 24
Step-by-step explanation:
The triangles are similar, so the sides are proportional.
The length of side BD is 10. The segment AD is also 10. Add them to get the length of side AB.
DE is 12
12:10 = y:20 . 20/10 = 2 2×12 = 24
