To meet the copper requirements of a growing pain, the feed must contain 4 mg copper per kilogram of dry matter of feed. if a pig is eating 5 pounds (on a dry matter basis) daily, how many milligrams of copper is the animal consuming?
a) 15 mg
b) 20 mg
c) 9 mg
d) 10 mg

option (c) 9 mg

Step-by-step explanation:

Data provided:

Amount of copper that must be contained in the feed = 4 mg per kilogram

Amount of dry matter being consumed by the pig = 5 pounds

Now,

1 pound = 0.45 kilograms

thus,

5 pounds = 0.45 × 5 = 2.25 kilograms

thus,

amount of dry matter being consumed by the pig = 2.25 kg

therefore,

the amount of copper consumed = 4 mg per kilogram × 2.25 kg

or

the amount of copper consumed = 9 mg

Hence,

the correct answer is option (c) 9 mg

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

1. 8

2. 9

3. 20

4. 3

5. 17

6. 2.2

7. 11.25

8. 1

9. 14

10. 2
