Kipp is making birdhouses for a park. the guidelines tell him how many of each wooden shape to use on one birdhouse. if he follows the guidelines, which statement is true?

A) For 8 birdhouse, he will need 16 trapezoids.

Step-by-step explanation:

Each birdhouse needs:

The following options are missing:

A) For 8 birdhouse, he will need 16 trapezoids.

B) For 12 birdhouses , he will need 16 rectangles  

C) The ratio of trapezoids to squares is 1 to 2

D) The ratio of squares to triangles is 2 to 1

A) The following proportion must be satisfied:

1 birdhouse / 8 birdhouses  = 2 trapezoids / x trapezoids

x = 2*8/1 = 16 trapezoids

Then, the A statement is true

B) The following proportion must be satisfied:

1 birdhouse / 12 birdhouses  = 4 rectangles / x rectangles

x = 4*12/1 = 48 rectangles

Then, the B statement is false.

C) There are 2 trapezoids for every 1 square, then the ratio of trapezoids to squares is 2 to 1.

Then, the C statement is false.

D) There is 1 square for every 2 triangles, then the ratio of squares  to triangles is 1 to 2.

Then, the D statement is false.

2.56 is the width of the garden

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
