Please I need help I’m giving 20 points for the answer please
strojnjashka [21]

Answer:

I would answer but in your question you said you are giving away 20 points when you are only giving away 15.... Make sure to state facts only.


Step-by-step explanation:

I'll answer anyways.....

You can make 0 different triangles. The angles/points would never line up right to make a triangle. Sorry if I'm wrong but I'm pretty sure this is right.

Order the steps for bisecting line segment AB using a reflective device.
yulyashka [42]

The question requires that segment AB is to be divided into two equal parts.

To do this, the order of steps for bisecting AB are D, E, B, C, A

To bisect segment AB implies dividing AB into two equal parts. After the construction, the length of each part must be equal.

Therefore, the required steps to bisect segment AB are as follow

<h3>What reflective device?</h3>

A MIRA is a commercial name given to a piece of colored transparent plastic used to reflect geometric objects.

D. Place the compass on point A, and open it wider than half the distance of the segment.

E. Swing an arc above and below the segment.

B. Keeping the compass the same width, place the compass on point B, and swing an arc above and below the segment.

C. Place points C and D on the intersection of the arcs created above and below segment AB.

A Draw a line from C point to point D.

Therefore the line CD is the perpendicular bisector of segment AB.

Thus, the order of steps for the bisection process is D, E, B, C, and A.

Three friends met for a book club at a coffee shop, each friend ordered a cup of coffee and two donuts. the total of the order w
4vir4ik [10]

Answer:

Cost\ of\ donut=\frac{49}{24}\approx \$2.042\\\\cost\ of\ donuts=\frac{49}{4}\approx \$12.25

Step-by-step explanation:

a.

Let\ cost\ of\ coffee=y\\\\cost\ of\ one\ donut=x\\\\Each\ friend\ buy\ one\ coffee\ and\ two\ donuts\\\\Amount\ for\ 1\ friend=Cost\ of\ coffee+2\times cost\ of\ donut\\\\Amount\ for\ 1\ friend=y+2x\\\\Amount\ required\ for\ 3\ friend=3\times Amount\ for\ 1\ friend\\\\Amount\ required\ for\ 3\ friend=3\times (y+2x)\\\\Amount\ required\ for\ 3\ friend=3y+6x\\\\Total\ bill=\$ 22\\\\3y+2x=22\\\\Given\ cost\ of\ coffee=\$3.25\\\\y=\$3.25

Hence\ solution\ of\ following\ system\ of\ equation\ will\ give\ cost\ of\ donut:\\\\3y+6x=22\\\\y=3.25\\\\\\Substitute\ y=3.25\ in\ first\ equation\\\\3\times 3.25+6x=22\\\\9.75+6x=22\\\\6x=22-9.75\\\\6x=12.25\\\\x=\frac{12.25}{6}\\\\x=\frac{49}{24}\approx \$2.042\\\\Cost\ of\ donut=\frac{49}{24}\approx \$2.042

See attached diagram.

b.

Each\ friend\ takes\ 2\ donuts\\\\Total\ donuts=Number\ of\ friends\times 2\\\\Total\ donuts=3\times 2=6\\\\cost\ of\ donuts=number\ of\ donuts\times cost\ of\ 1\ donut\\\\cost\ of\ donuts=6\times \frac{49}{24}\\\\cost\ of\ donuts=\frac{49}{4}\approx \$12.25
