The area of two similar octagons are 4 m2 and 25 m2. What is the scale factor of their side lengths
mylen [45]

Answer:

The scale factor of the sides of the Octagon is 2:5

Step-by-step explanation:

Both these octagons can be considered as the combination of 8 similar triangles joined edge to edge.

We know this property of similar triangles, that the ratio of area of similar triangles is proportion to the square of the ratio of sides of the similar triangle.

Side_{1} ^{2} : Side_{2} ^{2} =Area_{1} : Area _{2}

From the above property, we plug in the values

Side_{1} ^{2} : Side_{2} ^{2} =4: 25

Side_{1}  : Side_{2}  =2: 5

Therefore, the ratio of the sides of the Octagon are 2:5.

Raven needs new winter boots. Both Shoe Town and LaceUp shoe stores carry the boots
g100num [7]

Answer:

Raven should buy the boots at LaceUp since total cost is lower ($77.54)

Step-by-step explanation:

price of the boots at Shoe Town:

[$85.95 x (1 - 15%)] x (1 + 7.16%) = $73.06 x 1.0716 = $78.29

price of the boots at LaceUp:

{[$85.95 x (1 - 10%)] - $5} x (1 + 7.16%) = ($77.36 - $5) x 1.0716 = $72.36 x 1.0716 = $77.54

price of the boots at Run, Don't Walk (online store):

$71.99 + $6.50 = $78.49
