Consider the diagram.
Radda [10]

The congruence theorem that proves that △LON ≅ △LMN is: A. SSS congruence theorem

<h3>What is the SSS Congruence Theorem?</h3>

According to the SSS congruence theorem, if all three corresponding sides of two triangles are congruent, then both triangles are congruent.

In the image given, we have:

  • ON ≅ MN
  • LO ≅ LM
  • LN ≅ LN (reflexive property)

This means all three corresponding sides are congruent, therefore, the congruence theorem that proves both triangles are congruent is:

A. SSS.

Identify the following probability as theoretical or empirical.
nadezda [96]
Empirical data are gathered from experiments. This does not hold true for all species at all times. But the only way to know a certain datum for a certain specie at a certain situation, you do an experiment. However, theoretical data is more on the theory or concept of the situation. It formulates a general equation that could as much as possible hold true to all.

Therefore, this data is empirical.
The answer is A.

If f(x)=3-2x and g(x)=1/x+5, What is the value of (f/g) (8)?
Verizon [17]

(f/g)(8)=f(8)/g(8)

find f(8) and g(8) to mke it easier

f(8)=3-(8)=3-2(8)=3-16=-13

g(8)=1/(5+8)=1/13

so (f/g)(8)=-13/(1/13)=-13*13=-169

answer is -169

The size 4 soccer ball Sean’s team uses should weigh no more than 0.37 kilograms, and no less than 0.31 kilograms. A soccer bag
dmitriy555 [2]

Answers:

Q: What is the most they could weigh together?

A:  0.74 kg

-----

Q: What is the least they could weigh together?

A:  0.62 kg

=================================================

Work Shown:

x = weight of first ball

y = weight of second ball

each ball has a weight range of 0.31 kg to 0.37 kg, so,

0.31 \le x \le 0.37

0.31 \le y \le 0.37

add straight down to get

0.31+0.31 \le x+y \le 0.37+0.37

which simplifies to

0.62 \le x+y \le 0.74

the two soccer balls have a weight range of 0.62 to 0.74, inclusive of both endpoints.

--------

Without using algebra, you basically just add the smallest the two weights could be (0.31) to itself to get 0.31+0.31 = 0.62 which represents the smallest the two weights combined can be. The same happens with the largest weight of 0.37 to get 0.37+0.37 = 0.74 as the max weight of both objects together.
