Please help me prove that ED is congruent to BA! I thought I had it right by proving right and vertical angles, but I’m missing
Vikki [24]

Step-by-step explanation:

\overline{DA} \text{ bisects } \overline{EB}     is given

\overline{BC} \cong \overline{EC}  definition of <u>bisect</u>

<u />\overline{EB} \perp \overline{ED}, \, \overline{EB} \perp \overline{BA}  are both given

<u />\angle B, \, \angle E \text{ are right angles}  definition of perpendicular

\angle B \cong \angle E   because all right angles are congruent

\angle{ACB} \cong \angle{DCE}  vertical angles are congruent

\triangle{ACB} \cong \triangle{DCE}   ASA (angle-side-angle)

\overline{ED} \cong \overline{BA}  CPCTC (corresponding parts of congruent triangles are congruent)

Shonda’s car gets an average of 27 miles per gallon. Gas costs $2.25 per gallon and she drives 892 miles to get from Baltimore,
bekas [8.4K]

She will spend $74.25 on gas.

Step-by-step explanation:

Given,

27 miles = 1 gallon

1 mile = \frac{1}{27}\ mile

Distance to cover = 892 miles

We will multiply this number with gallons of gas used for 1 mile.

892 miles = \frac{1}{27}*892

892 miles = 33.04 gallons of gas

Rounding off to nearest whole number;

892 miles = 33 gallons

Cost of one gallon of gas = $2.25

Cost of 33 gallons = 2.25*33 = $74.25

She will spend $74.25 on gas.

Write the total population of india and china.estimate the total population by rounding off each population to nearest 100000
adell [148]

<span>As of Thursday, August 17, 2017, based from the data of the latest United Nations estimates, the current population of China is 1,388,979,446.</span>


China’s population is equivalent to 18.47% of the total world population.


18.47%<span> of the total world population is composed by China’s population.


</span>

<span>China is ranked number 1 in the list of countries by population.</span>


Rounding that number off to the nearest 100,000, it would be 1,388,980,000.

 

As of Thursday, August 17, 2017, based from the data of the latest United Nations estimates, the current population of India is 1,344,431,890.

A transformation of ΔDEF results in ΔD'E'F'.
sladkih [1.3K]

Answer:

Rotation

Step-by-step explanation:

A transformation of a triangle can be either dilation or reflection or rotation or a translation.

Dilation happens when a symmetric figure is formed with scale factor other than 1.  But here both triangles have same side length.  Hence no dilation

Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on  a line.  Hence no reflection

Rotation is keeping the same shape but rotating through a certain angle.  Here DEF is rotated without disturbing its shape or size through a certain angle. Hence rotation is right

Translation is not right because there is no vertical or horizontal shift to get new triangle.
