Answer:

43 feet

Step-by-step explanation:

The shadow cats by the stick was 5 feet long while the actual stick is only 3 feet long which means the shadow makes it bigger by 2 feet. Take 2 feet away from 45 feet you will get 43 feet.

I hope you understand if you dlnt I will explain it more. Hope it helped too!

What is the area of parallelogram ABCD?<br><br><br> ____ square units
valentinak56 [21]

Answer:

13

Step-by-step explanation:

Here's a method of finding the area of any polygon knowing its vertices. I'm using this parallelogram as an example.

Make a table like this (each vertex with its x- and y-coordinates):

Pt    x       y

A     3      6

B     6      5

C     5      1

D     2      2

A     3      6

Now multiply each x-coordinate by the y-coordinate on the line below and write it on the right side. Bold type shows the first multiplication.

       x       y

A     3      6

B     6      5      15

C     5      1        6

D     2      2      10

A     3      6      12

Now multiply each y-coordinate by the x-coordinate on the line below and subtract from each produce you already have. Do each subtraction. Bold type shows the first multiplication.

       x       y

A     3     6

B     6      5      15 - 36 = -21

C     5      1        6 - 25 = -19

D     2      2      10 - 2 =     8

A     3      6      12 - 6 =     6

Add all the differences.

       x       y

A     3      6

B     6      5      15 - 36 = -21

C     5      1        6 - 25 = -19

D     2      2      10 - 2 =     8

A     3      6      12 - 6 =     6

                                   +____

                                       -26

The area of the polygon is the absolute value of half of the sum of the differences.

area = |-26/2| = |-13| = 13

Vladimir [108]

Answer:

A- X= 20÷5-3

B- 20÷5=4; 4-3=1

C- X=1

Step-by-step explanation:

Okay, well we have to work backwards. 20 cookies, and she makes 5 bags. We need to find out what 'x' means. To do that, we take 20 cookies and divide it by 5. 4 cookies. Then we want to take 3 cookies out of each bag to find out how many cookies she first put in. 1 cookie.

Let's check:

bag 1:

o (one cookie)

bag 2:

o (one cookie)

bag 3:

o (one cookie)

bag 4:

o (one cookie)

bag 5:

o (one cookie)

Now we have 15 cookies left. Now let's put 3 in each:

bag 1:

o (one cookie)

v v v ( three cookies)

bag 2:

o (one cookie)

v v v ( three cookies)

bag 3:

o (one cookie)

v v v ( three cookies)

bag 4:

o (one cookie)

v v v ( three cookies)

bag 5:

o (one cookie)

v v v ( three cookies)

Now we have no cookies left, and we put 4 cookies in each. (o representing the first cookie, v representing the next three cookies)

A puzzle contains a triangular piece with a base of 3 in. and a height of 4 in. A manufacturer wants to make 80 puzzles. Find th
kari74 [83]
Since the base is 3 inches and the height is 4 inches, as well as the area of a triangle being base*height/2, we get 3*4/2=6 in. for each triangle. Since we need 20 pieces for each puzzle, we multiply 6 by 20 to get 120. In addition, since 80 puzzles are needed, with 20 pieces for each puzzle, we have 120 inches for each puzzle and 120*80 = 9600 square inches of wood used
