Answer:

b=\dfrac{1}{5}a.

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.

b=f(a)

b\propto a

b=ka     ...(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).

3=k(15)

k=\dfrac{3}{15}=\dfrac{1}{5}

Substitute k=\dfrac{1}{5} in (1).

b=\dfrac{1}{5}a

Therefore, the required function is b=\dfrac{1}{5}a.

Please help me with this question​
stira [4]

Step-by-step explanation:

The river is 1000 m wide, and the boat moves at 3 m/s, so the time it takes to cross the river is:

t = (1000 m) / (3 m/s)

t = 333.3 s

The river flows at 2 m/s, so by the time he reaches the other bank, he drifts downstream a distance of:

d = (2 m/s) (333.3 s)

d = 666.7 m

From the list of these numbers 3,5,7,12,15,18,20<br> What is a factor of 10
il63 [147K]
The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10.
