Tucker's Road Paving Company used 646.5 tons of cement to pave 4 miles of roadway. To the nearest hundredth of a ton, how much c

andreev551 [17]

Answer:

161.63 tons

Step-by-step explanation:

Cement used per mile = total cement used / total miles

646.5 tons / 4 = 161.625 tons

161.63 tons to the nearest hundredth

the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero

the thousandth term is 5, so 1 would be added to 2

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.

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