Which are the correct classifications for the polygon?

Mathematics

Yakvenalex [24]3 years ago

I believe the correct answer from the choices listed above is option A. THe correct classification of the polygon in the figure would be a concave hexagon. Counting the number of sides, we have 6 sides making it a hexagon. It is concave since one side is <span>hollowed inward.</span>

Which transformation maps the pre-image, DEFG, to the image, D'E'F'G'?
netineya [11]
The answer is letter B. The image shows a relection because it is just the same as the original. Reflection is a transformation that gets the 2nd image just the same as the original. The transformation of DEFG is just the same as D'E'F'G'.

Answer:

<h2>3 3/4 Crates of Oranges</h2>

Step-by-step explanation:

We use a proportion to solve this. There are many steps involved, so I'll put each one separate, so you can easily follow.

<h3>Step 1: Set Up a Proportion</h3>

\frac{0.5}{2.5} = \frac{0.75}{x}

<h3>Step 2: Cross-Multiply</h3>

\frac{1}{2}x = \frac{3}{4} * 2\frac{1}{2} \\\frac{1}{2}x = 1\frac{7}{8} \\

<h3>Step 3: Isolate x</h3>

1\frac{7}{8} * 2 = 3\frac{3}{4}

x = 3\frac{3}{4}

<h3>Step 4: Check</h3>

\frac{0.5}{2.5} = \frac{0.75}{3.75}

\frac{1}{2} * 3\frac{3}{4} = \frac{3}{4} * 2\frac{1}{2}

1\frac{7}{8} = 1\frac{7}{8} ✔

<h3>Step 5: Answer</h3>

3 3/4 crates of oranges

I'm always happy to help :)

Hey, can you guys help me out with this question? I need the workings too.( find the surface area )
Ilia_Sergeevich [38]

▪︎Side 15 cm, 18 cm and x cm form a right angle triangle.

We know that :

=\tt  {hypotenuse}^{2}  =  {leg}^{2}   +  {leg}^{2}

Which means :

=\tt  {15}^{2}  +  {x}^{2}  =  {18}^{2}

=\tt 225 +  {x}^{2}  = 324

=\tt  {x}^{2}  = 324 - 225

= \tt {x}^{2}  = 99

\color{plum} =\tt x = 9.9 \: cm

Thus, x (radius) = 9.9 cm

We know that :

\color{hotpink}\tt \: Surface \:  area \:  of \:  cone \color{plum}=\pi r(r +  \sqrt{ {h}^{2}  +  {r}^{2} }

Then, the surface area of this cone :

= \tt3.14 \times 9.9 \times( 9.9 +  \sqrt{ {15}^{2}  +  {9.9}^{2} } )

=\tt 3.14 \times 9.9 \times( 9.9 +  \sqrt{323.01} )

=\tt 3.14 \times 9.9 \times (9.9 + 18)

=\tt 3.14 \times 9.9 \times 27.9

= \tt31.09 \times 27.9

\color{plum} =\tt\bold{ 867.4 \: cm}

Therefore, the surface area of this cone = 867.4 cm
