A veterinarian knows that a 50-pound dog gets 0.5 milligram of a certain medicine, and that the number of milligrams, m, varies

directly with the weight of the dog, w. The vet uses these steps to find the amount of medicine to give a 10-pound dog. Step 1 Find the constant of variation. Step 2 Write the direct variation equation. Step 3 Substitute 10 into the equation to find the dosage for a 10-pound dog. Step 4 Solve for w. The 10-pound dog needs 1000 milligrams. In which step did the veterinarian make the first error? Step 1 Step 2 Step 3 Step 4

1. Divide the amount needed by the weight:

0.5 milligram / 50 pounds = 0.01 milligram per pound.

2. m = 0.01w

3. m = 0.01(10)

4 m = 0.01 x 10

0.1 milligrams

The error was step 1.

Answer:

17.5

Step-by-step explanation:

Pythagorean Theorem is a^2 + b^2 =c^2

a= 9 , b= 15, c= x

\sqrt{306}= c^2

c= 17.493 or 17.5 rounded to the nearest tenth

Answer:

x = 3, x = 0

Step-by-step explanation:

To solve these factored equations, just divide each part by zero and solve.

2x(x-3) = 0 → (x-3) = 0, and 2x = 0.

(x-3) = 0 → x - 3 + 3 = 0 + 3 → <u>x = 3.</u>

2x = 0 → 2x/2 = 0/2 → <u>x = 0.</u>
