Answer:

<em>Total amount of material would be ⇒ 5 square feet</em>

Step-by-Step Explanation:

~ The amount of material is, simple put, the surface area of the boxes. Knowing that, let us calculate the area of each surface of the first net, for simplicity: 0.5 * 1 = 0.5 ft^2, 0.5 * 2 = 1 ft^2, 1 * 2 = 2 ft^2. Now two of these area are congruent to another surface, such that the amount of material needed for the first net is 0.5 * 2 + 1 * 2 + 2 = 1 + 2 + 2 = 5 feet^2.

<em>Knowing that amount of material for each net is 5 ft^2, the total amount of material would be ⇒ 5 feet^2</em>

Answer:

The answer is "12 inches".

Step-by-step explanation:

Please find the image file of the graph.

We know $AE = CF \ and \ EB = FB$ so because the triangle is isosceles.

$EB = 2x, FB = 2x,\ and \ CF = x$ when $AE$ is called by $x$ .

We know that $AE = AD = x$ since E and D are tangent points to a circle.

They have $CD = CF = x$ since D and F are tangent points only to circle.

Thus, if the perimeter is 32, the following is the result:

$\to AE + EB + BF + FC + CD + DA = 32\\\\\to x + 2x + 2x + x + x + x = 32\\\\\to 8x = 32\\\\\to x = 4$

Therefore the length of $BC = BF + FC = 2x + x = 3x = 12\ inches$

Please somebody help me with this please help ASAP

Step-by-step explanation:

I don't know what your teacher wants to hear here.

can you use and construct certain angles (particularly 90 degrees), can you use compasses ?

for me the best way would be to draw one side as given. then use compasses and draw a half-circle from each end point of the line above the line. both circles have the radius = the given diameter.

then draw the next 2 sides of the square up from the end points of the first line towards the half-circle that was drawn from the other point, so that the end point is exactly on the circle bow. and then connect the engaging endpoints of these 2 sides.

similar for the rectangle.

the only difference is that now for the two sides (which we don't know the length) we need to go up exactly 90 degrees until the lines hit the half-circles.
