Answer:
81 pounds
Step-by-step explanation:
First find what 12.5% of 72 pounds is, so you can add that number to 72 pounds to find the ideal weight.
12.5% of 72 can be calculated by multiplying 72 by .
That is: pounds.
So the dog's ideal weight is 72 plus 9 = 81 pounds
<span>An equation that contains a radical expression is called a radical equation. Solving radical equations requires applying the rules of exponents and following some basic algebraic principles. In some cases, it also requires looking out for errors generated by raising unknown quantities to an even power.</span>

Answer:
13/20
Step-by-step explanation:
Another way of asking this question is to ask for the difference of 1/4 and 9/10. The equation will start with 9/10 - 1/4.
9/10 - 1/4
Equations can only be added or subtracted when the denominators (bottom numbers) are the same. To do this, you must find a number that can be divided by both denominators. In this case, 20 can be divided by 4 and 10.
(9*2)/(10*2) = 18/20
(1*5)/(4*5) = 5/20
18/20 - 5/20 = 13/20
13/20 cannot be simplified as 13 is a prime number
13/20
✔8 Isn't a perfect square. Irrational numbers are numbers that cannot be represented as a ratio for example Pi, or non-perfect squares like ✔2, ✔3, ✔5, ✔8.
