Let's say you have two line segments, AB and CD which bisect each other at point E. Explain why AC = DB.

Answers

Answer:

[tex]AC=DB[/tex]

(corresponding parts of congruent triangles are equal)

Step-by-step explanation:

Consider triangles ACE and BDE.

As AB and CD bisect each other at point E,

[tex]AE=BE\\CE=DE[/tex]

As AB and CD intersect each other at point E and vertically opposite angles are equal,

∠AEC = ∠BED

So,

ΔAEC ≅ ΔBED       (Using SAS congruence criteria)

(According to SAS congruence criteria, if two sides and the included angle of one triangle are equal to the corresponding two sides and the included angle of another triangle then the two triangles are said to be congruent.)

Hence,

[tex]AC=DB[/tex]

(corresponding parts of congruent triangles are equal)

When segments AB and CD bisect each other at point E, the two triangles formed, [tex]\triangle AEC $ and $ \triangle BED[/tex], are congruent to each other SAS Congruence Theorem, therefore, AC = DB.

Recall:

Congruent triangles have equal sides and equal angles that corresponds to each other.

Line segments AB bisecting line segment CD at point E will give us the triangles AEC and BED if we join A to C, and B to D.

Thus, the following information can be deduced from the image of both triangles shown in the attachment below:

[tex]EC \cong ED\\\\AE \cong BE[/tex] (congruent segments)

[tex]\angle AEC \cong \angle BED[/tex] (vertical angles)

From the above stated, [tex]\mathbf{\triangle AEC \cong \triangle BED}[/tex] by the SAS Congruence Theorem.

Since both triangles are congruent, all their corresponding sides would be congruent, therefore AC = DB.

In summary, when segments AB and CD bisect each other at point E, the two triangles formed, [tex]\triangle AEC $ and $ \triangle BED[/tex], are congruent to each other SAS Congruence Theorem, therefore, AC = DB.

A principal of $4500 is invested at 4.25% interest, compounded annually. How much will the investment be worth after 12 years?
Use the calculator provided and round your answer to the nearest dollar.

Answers

The money will be worth 7412 at the end of the 12th year.

What is compound interest?

Compound interest is the interest that accrues on a loan or deposit on both the initial interests and principal.

Analysis:

To calculate the amount after 12 years we use the compound interest formula, A = P[tex](1 + \frac{r}{100} )^{n}[/tex]

where A = amount after a period of time, P = initial principal = 4500, r = rate = 4.25, n = number of years = 12.

 A = 4500[tex](1 + \frac{4.25}{100} )^{12}[/tex] = 7412

In conclusion, 7412 dollar will be realized at the end of the 12th year.

Using partial quotients, which would be the best choice for the first number to subtract in the division problem 673 divided by 25?

Answers

Answer:

Best for choice for the first number to subtract = 500

Step-by-step explanation:

The dividend is 673 while the divisor is 25

First step is to subtract from the dividend an easy multiple like 100 times the divisor,20 times the divisor, 10 times the divisor, 5 times the divisor 2 times the divisor etc.

The best choice for the first number to subtract will be 20 times the divisor because when we multiply 20 by 25 and subtract from 673,we will get 173. And the next quotient will be 6 which is in units as the first one of 20 was in tens.

Best choice to subtract = 20 × 25 = 500

Answer: 500

Malcolm and Theo's families are both traveling to the same vacation resort.
The equation d=65t models the distance, d, that Malcolm's family travels after t hours.
The graph below shows the relationship between the distance and the amount of time that Theo's family traveled.

Answers

Solution :

Equation for Malcom's family travels after t hours is d = 65 t

From the graph, equation for Theo's family travels after travels after t hours is

[tex]$d=\frac{225}{4.5}t$[/tex]

[tex]$d=50 t$[/tex]

For Malcom's family, speed [tex]$= \frac{d}{t}$[/tex] = 65 miles per hour

For Theo's family, speed [tex]$= \frac{d}{t}$[/tex] = 50 miles per hour

Malcom's family traveled faster than Theo's family by

        = (65-50) miles per hour

        = 15 miles per hour
