There are 10 lanes in the bowling alley where Harold bowls. He wants to make a scale drawing of the bowling alley using a scale of 3 cm to 15 ft. One lane, including gutters, is 60 ft long and 5 ft wide. What will the width of all 10 lanes on his drawing be?

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

just took the test and my answers down below!

step-by-step explanation:

check the pic :

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
