PRACTICE EXERCISE 1: I Can Do This! DIRECTIONS: Sove the problems involving direct and inverse variation. Write your answer iin fraction or decimal form. 1. The shadow of an object varies directly as its height h. A man 1.8 m tall casts a shadow 4.32 m long. If at the same time a flagpole casts a shadow 12.8 m long, how high is the flagpole? STEP 1: Write the correct equation. Direct variation problems are solved using the equation y = kx. STEP 2: Use the information given in the problem to find the value of k. STEP 3: Rewrite the equation from step 1 substituting in the value of k found in step 2. STEP 4: Use the equation found in step 3 and the remaining information given in the problem to answer the question asked.

I Can Do This!
DIRECTIONS: Sove the problems involving direct and inverse variation.
Write your answer iin fraction or decimal form.
1. The shadow of an object varies directly as its height h. A man 1.8 m tall casts a shadow
4.32 m long. If at the same time a flagpole casts a shadow 12.8 m long, how high is the
flagpole?
STEP 1: Write the correct equation. Direct
variation problems are solved using the
equation y = kx.
STEP 2: Use the information given in the
problem to find the value of k.
STEP 3: Rewrite the equation from step 1
substituting in the value of k found in step 2.
STEP 4: Use the equation found in step 3
and the remaining information given in the
problem to answer the question asked.
