The scale factor used was 1/2. It is a reduction because the prime figure is smaller.

The polygons are not similar because the ratio of their corresponding sides are not the same and do not simplify to be the same either.

Answer:

1) The square ABCD was dilated to form square A'B'C'D' using a scale factor of 1/2

2) The pair of polygons is not similar because their corresponding sides are not proportionals.

Step-by-step explanation:

1) Scale factor: f=?

f=Final dimension / Initial dimension

f=A'B'/AB=B'C'/BC=C'D'/CD=A'D'/AD

f=2/4

Simplifying the fraction dividing the numerator and denominator by 2:

f= (2/2) / (4/2)

f=1/2

2) Let's check the proportion between their corresponding sides:

AM/A'M'=(11 ft)/(9.4 ft)=1.17

HT/H'T'=(11 ft)/(9.4 ft)=1.17

HM/H'M'=(10 ft)/(8.4 ft)=1.19

AT/A'T'=(10 ft)/(8.4 ft)=1.19

AM/A'M'=HT/H'T'=1.17 but different to 1.19=HM/H'M'=AT/A'T'

Then, the pair of polygons is not similar

Shawn has 186 feet of fencing and plans to make a pig pen that is 15 feet wide. How long will the pig pen be? Remember the formu

Nadusha1986 [10]

Answer:

The length of the pig pen for fencing the plans is 28 feet .

Step-by-step explanation:

Given as :

The measure of the fencing = 186 feet

The width of the pig pen = w = 15 feet

Let the length of the pig pen = l = x feet

Now, To find the measure of the fencing , we calculate the perimeter of the plans .

So, From perimeter method

I.e Perimeter = 2 × Length + 2 × Width

or, 186 feet = 2 × l + 2 × w

Or, 186 feet = 2 × l + 2 × 15

Or, 186 - 2 × 15 = 2 × l

or, 186 - 30 = 2 × l

Or, 2 × l = 156

∴ l = $\frac{156}{2}$ = 78 feet

So, The length of pig pen = l = 28 feet

Hence The length of the pig pen for fencing the plans is 28 feet . Answer

If n+1 integers are chosen from the set

baherus [9]

Answer:

Pigeonhole Principle

Step-by-step explanation:

From series {1,2......2n} ; we need to select 'n + 1' integers.

Even integers series from above series = {2,4,6..........2(n-1), 2n}

Odd integers series from above series = {1,3,5........2(n-2), 2n-1}

So, we can choose only n odd integers from the series. Hence, if we choose n+1 integers, atleast one of them have to be even integer.

Eg : n = 5, Series = (1,2,3,4,5,6,7,8,9,10}, Odd series = {1,3,5,7,9}, Even series = {2,4,6,8,10}. If we choose 5 +1 ie 6 integers, there must be one even integer, as there are only 5 total odd integers in series.

It is snowing and salt trucks are

Korolek [52]

Answer:

The volume of a mound of salt-sand mixture is 589.05 feet ³ or 589.05 cubic feet.

Step-by-step explanation:

1. Let's check the information given to resolve the question:

Diameter of a mound of the mixture = 15 feet

Height (h) of the mound of the mixture = 10 feet

How much salt-sand mixture is there?

2. Let's find the volume of a mound of mixture with a conical shape:

For doing that, we need to use the volume formula of a cone.

It's: 1/3 * π * r² * h

Replacing with real values, we have:

1/3 * 3.1416 * 7.5 ² * 10 (Diameter = 15, so radius = Diameter/2 = 15/2 = 7.5)

Volume = 1/3 * 3.1416 * 56.25 * 10

Volume = 1/3 * 3.1416 * 562.5 (56.25 * 10 = 562.5)

Volume = 187.5 * 3.1416 = 589.05 feet ³ or 589.05 cubic feet.
