When trying to gather information in order to identify a problem, it is important to _______.a. Evaluate the best course of action
b. Find reliable sources
c. Embrace your assumptions
d. Generate multiple solutions

Answers

When trying to gather information in order to identify a problem, it is important to find reliable sources.

What is a reliable source?

A reliable source is known to be that source of information that gives a thorough, well-think through theory, argument, etc. and it is one that is found to be true.

So therefore, When trying to gather information in order to identify a problem, it is important to find reliable sources.

Explain how you can use base ten block to find 2.16÷3

Answers

You can use base ten blocks to find 2.16/ 3 by using 7 base ten blocks and 2 base one blocks.

you can take two hundreds blocks and then 16 tenths then just divide.

Just a note before I get started: The specific theorem/postulate/definition will be given in quotes. Everything else will be explanation of why we will use itLets get started :D
b. We can use the "definition of a square" because it states that it a square, every side is congruent. We can use this because we already know that the shape is a square due to a.

c. We can use "definition of a square" again for the same reason as b.

e. We know that the hypotenuses (hypoteni?) of both triangles are congruent, and they both share a side, so we can use the "Hypotenuse Leg Theorem"

f. Because we know that the triangles are congruent, we can use the "Base Angle Theorem" to say that the angles are congruent.

h. Because they share the same side, we can use the "Linear Pair Theorem" to say that they are supplementary angles

In mathematics, a proof is a deductive argument for a mathematical statement. In the argument, other previously established statements, such as theorems, can be used. In principle, a proof can be traced back to self-evident or assumed statements, known as axioms.

What is a number line?

A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.

Given that a candy store sells different size bags of jelly beans. The line plot shows the weights of ten bags. Mikayla bought all of the. bags weighing less than 3/8 pound

The number of jelly beans will be calculated as,

1/4 = 2/8 ( 1/4 x 2/2 )

2/8 + 1/8 = 3/8 pounds
