[scale factor]=[length miniature skateboard]/[length <span>actual skateboard] </span>[length miniature skateboard]=3.8 in [length actual skateboard]=31.75 in [scale factor]=[3.8]/[31.75]=0.12 in/in
<span>(a) What is the scale factor for the tech deck? the answer Part A) is 0.12 in/in
</span><span>(b) If the width of the actual skateboard is 8”, what is the width of the tech deck? </span>[scale factor]=[width miniature skateboard]/[width actual skateboard] [width miniature skateboard]=[width actual skateboard]*[scale factor] for width=8 in [width miniature skateboard]=[8]*[0.12]----------> 0.96 in
the answer part B) is 0.96 in
<span>c) Measure the length of your own foot. If you were designing a doll that was a scale model of you, and you wanted it to be able to use the tech deck as its skateboard, how long should the doll’s foot be? </span> the length of my own foot is 25 cm--------> 25/2.54---------> 9.84 in [scale factor]=[doll foot]/[actual foot] [doll foot]=[scale factor]*[actual foot]--------> 0.12*9.84-----> 1.18 in
