avanturin [10]4 years ago

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.

Tom went with his dad to a shooting range. His dad bought him 10 bullets. For every time he got bullseye, the father gave his so
marusya05 [52]

Answer:  Tom hit the bullseye 23 times .

Step-by-step explanation:

Let the number of times Tom hit the bullseye be 'x'

Since we have given that

Total number of times Tom shot = 55

Number of times he missed the shot be '55-x'

Number of bullets he already have = 10

According to question, For every time, he got bullseye, the father gave him an extra bullet and after every miss he took one away.

At last he ran out of bullets.

So, it becomes,

10+1\times x-1(55-x)=0\\\\10+x-55+x=0\\\\2x-45=0\\\\2x=45\\\\x=\frac{45}{2}=22.5\\\\\text{ But number of times can't be in decimal }\\\\So,\ x=23

Hence, Tom hit the bullseye 23 times .
