Keywords:

<em>perimeter, square, base, pyramid, kilometers, side </em>

For this case we must find the perimeter of the base of a square pyramid, whose side of the square measures 160m. In addition, the measure obtained must be converted to kilometers. So, we have by definition the perimeter of a square is the sum of its sides, which is equivalent to P = 4l, where "l" is the side of the square.

Ifl = 160m, then:

P = 4 * 160m\\P = 640m

Thus, the perimeter of the base of the pyramid is 640m.

On the other hand, by definition: 1Km = 1000m

By making a rule of three we have:

1Km ---------> 1000m

x --------------> 640m

Where "x" represents the perimeter of the base of the pyramid in Km.

x = \frac {640 * 1} {1000}\\x = 0.64km

Thus, the perimeter of the base of the pyramid is 0.64Km

Answer:

The perimeter in kilometers is 0.64

REY [17]

Answer:

Option C is correct. Option f is the same as option C

Step-by-step explanation:

From the question, There are three high schools in the district, each with grades between nine to twelve. The school board decided to pool all of the students together and randomly samples 250 students in the whole district that has schools between the grade of nine to twelve.

In order to test for high school students in the district for Attention Deficit disorder(ADD), they could have chosen any 250 students from any school with grades betweem nine to twelve throughout the district.

Describe a similarity transformation that maps △ABC
PIT_PIT [208]

Let's start with a picture.

We see RST is smaller, and BC is parallel to but in the opposite direction to its corresponding segment ST.  Both have slope -1.

If we look at the difference of points (technically called vectors but we don't have to go there) we get

C-B=(-2,2)

T-S=(1,-1)

Without further calculation we can see T-S is half the length of C-B.

The problem asks for a dilation followed by a reflection.   We know the dilation scale is k=1/2 because the new triangle is half the size.  

After dilation we get A'B'C':

A'(3,2), B'(-1,0), C'(-2,1)

We see now we need a reflection that flips the coordinates x and y.  That's the +45° line through the origin, namely y=x.

Answer: k=1/2, y=x

lord [1]

Answer:

960

Step-by-step explanation:

x = 0.6x + 384

Subtract 0.6x from both sides.

0.4x = 384

Divide both sides by 0.4

x = 960
