Answer:
Step-by-step explanation:
Height of the cone h = 15 in
Radius of the cone r = 12/2 = 6 in
We need to find slant height (l) =?
2
Step-by-step explanation:
it kinda like subtracting to get your answer
$6.79 - $3.95 = $2.84. Since you’re rounding to the nearest half dollar, you’d found to $3. $2.84 is closer to $3 than $2.50
$3 - $2.84 = $.16
$2.84 - $2.5 = $.34
54 = 3x + 37.5 <== ur equation....and x = number of years
54 - 37.5 = 3x
16.5 = 3x
16.5 / 3 = x
5.5 = x......so it would take 5.5 years...or 5 1/2 years <=
We know that
[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
the answer part C) is 1.18 in
