Answer:

  C. Only Henry's proof is correct.

Step-by-step explanation:

Amy's "proof" leaves out the steps that Henry's proof puts in. Only Henry's proof is correct.

__

Amy's proof has no reasoning to support her "therefore ..." and no reasoning to support her conclusion that angles 4 and 2 are equal. Nothing in her proof supports her conclusion that the transitive property of equality can be applied.

An object is translated by (x-2, y-6). If one point in the pre-image has the coordinates (-3, 7,) what would be the coordinates
Katen [24]

Answer:

(- 5, 1 )

Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 2, y - 6 )

This means subtract 2 from the original x- coordinate and subtract 6 from the original y- coordinate, that is

(- 3, 7 ) → (- 3 - 2, 7 - 6 ) → (- 5, 1 )

One teacher wants to give each student two and 1/6 slices of pizza if the teachers had 13 slices of pizza how many students will
hram777 [196]

Answer:

6 students.

Step-by-step explanation:

First let's combine 2 and 1/6.

6/6 + 6/6 + 1/6 = 13/6.

Now we will turn 13 to 13/1 and divide by 13/6

\frac{13}{1}  \div  \frac{13}{6}  =  \frac{13}{1}  \times  \frac{6}{13}

\frac{13 \:  \times  \: 6 \:  =  \: 78}{ 1 \times \:  13  \: =  \: 13}

78 \div 13 = 6

So, the teacher will hand the pizza out to 6 students.

Match the following items.
max2010maxim [7]

Answer:

1. ∠ABD = 20°.

2.  Arc AB =  140°.

3.  Arc AD =  40°.

Step-by-step explanation:

Given information: ∠ADB = 70°. BD is diameter.

According to Central angle theorem, the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points.

By Central angle theorem,

\angle DAB=90^{\circ}

Using angle sum of property in triangle ADB we get,

\angle ADB+\angle DAB+\angle  ABD=180^{\circ}

70^{\circ}+90^{\circ}+\angle  ABD=180^{\circ}

\angle  ABD=20^{\circ}.

Draw a line segment AO.

In triangle AOD, AO=OD, so

\angle ODB=\angle OAD=70^{\circ}

Using angle sum property in triangle AOD,

\angle AOD+\angle ODA+\angle  OAD=180^{\circ}

\angle AOD+70^{\circ}+70^{\circ}=180^{\circ}

\angle AOD=40^{\circ}

Therefore length of arc AD is 40°.

The angle AOD and AOB are supplementary angles.

\angle AOD+\angle AOB=180^{\circ}

40^{\circ}+\angle AOB=180^{\circ}

\angle AOB=140^{\circ}

Therefore length of arc AB is 140°.
