Answer:
Thus, a golden retriever should be given 19 teaspoon of medicine.
Step-by-step explanation:
- Given that a golden retriever weighing 85 pounds has diarrhea. His medicine is prescribed as 1 teaspoon per 5 pounds.
- To find how much medicine should he be given.
- Assign a variable. Write a sentence that gives the information to find it.
- Translate into a proportion be careful of the units.
- Multiply both sides by the Least Common Denominator and simplify. Check the answer.
Step 1 of 3
Write the data in mathematical form and simplify.
Let x=the number of teaspoon
If 1 teaspoon medicine is 5 pounds then 85 pounds is how many teaspoon of medicine.
Translate the statement into proportion.
Step 2 of 3
Multiply both sides by x and simplify
5x=85
Divide by 5,
<em>Simplify, x=19</em>
<em>Step 3 of 3</em>
<em>Check the answer.</em>
<em>Substitute x=19 in original proportion and simplify.</em>

<em> The radius of a circle is 10 m. Find its area to the nearest whole number.</em>
<em />
<em />
We're asked to find the area of the circle, which we can find using the following formula:-
Where:-
- π = pi [3.14...]
- r=radius (10 m)
Substitute 10 for r and 3.14 for π:-
On simplification,
On further simplification,
The Area is:-
Note:- Area is always measured in units² (units squared)
