55-34=21--can

55-40=15--can

55-38=17--can

combo of 3

1,3,5=9

137=11

139=13

Patricia is building the community dog park. She plans to build the dog park right beside the city park so she can use one side
slamgirl [31]

Answer:

85 feet by 170 feet

Step-by-step explanation:

This one relies on Calculus.

so you have 340   feet.

Let  x = width,   y = length of rectangle

one side of this rectangle will not use the new fence material

so  2x + y = 340 feet.

Area = x*y

We want to maximize  Area

Area  A = x*y = x*(340 - 2x)

Take the derivative of A  w.r.t.  x

dA/dx =  340 - 4x

set it to 0

340 - 4x = 0

4x = 340

x = 85 feet

and y = 340 - 2x = 340 - 2*85 = 340 - 170 = 170 feet

Which number has a greater value than |-2.6|?
Archy [21]

Answer: I'm assuming that there were multiple choices provided for this question.. but just to help you, when a number is within the absolute value, it changes any number to a positive:

|-2.6| = 2.6

So any number higher than that work for this question :-)

Which of these triangle pairs can be mapped to each other using a translation and a rotation about point A?
Vladimir79 [104]

Answer:

<u>Figure A</u>

Step-by-step explanation:

See the attached figure which represents the given options

We are to select the correct pair of triangles that can be mapped to each other using a translation and a rotation about point A.

As shown: point A will map to point L, point R will map to point P and point Q will map to point K.

we will check the options:

<u>Figure A</u>: the triangle ARQ and LPK can be mapped to each other using a translation and a rotation about point A.

<u>Figure B: </u> the triangle ARQ and LPK can be mapped to each other using a translation and a reflection about the line RA.

<u>Figure C:</u> the triangle ARQ and LPK can be mapped to each other using a translation and a reflection about the line QA.

<u>Figure D:</u> the triangle ARQ and LPK can be mapped to each other using a rotation about point A.

So, the answer is figure A

<u>The triangle pairs of figure A can be mapped to each other using a translation and a rotation about point A.</u>
