<u>A cross section parallel to the base is a square measuring 4 cm by 4 cm </u>

<u>Step-by-step explanation:</u>

Here we have to select the correct  statement regarding a cross section of the cube :

<u>A cross section parallel to the base is a square measuring 4 cm by 4 cm :</u>

Since , every side of a cube is same  . Any cross section of a cube must be parallel to a square base . Hence, correct statement .

<u>A cross section parallel to the base is a rectangle measuring 4 cm by greater than 4 cm :</u>

Since , every side of a cube is same  . Any cross section of a cube must be parallel to a square base . Here, base is rectangle . We don't have a rectangle base in cube . Not correct statement.

<u>A cross section perpendicular to the base through the midpoints of opposite sides is a rectangle measuring 2 cm by 4 cm:</u>

Since , every side of a cube is same  . Any cross section of a cube must be parallel to a square base . Here, base should be square not rectangle . So ,  Not correct statement.

6r - 7 over 10 = r over 4
Ahat [919]
Multiply both sides by 4

subtract 24r from both sides

simplify r - 24r to -23r

divide both sides by -23

two negatives make a positive

simplify 14/5/23 to 14/5 x 23

simplify 5 x 23 to 115

switch sides

Answer: r = 14/115.

Fill in the blanks to complete the proof
-BARSIC- [3]

The blanks in this two-column proof should be filled as follows:

<u>Statements                                             Reasons</u>_______________

m∠1 = m∠3                                                Given

m∠CBA = m∠ABE + m∠CBD            Angle Addition Postulate  

m∠ABE = m∠3 + m∠2              Substitution Property of Equality          

m∠CBD = m∠3 + m∠2              Substitution Property of Equality

m∠ABE ≅ m∠CBD                    Transitive Property of Equality

<h3>What is the Angle Addition Postulate?</h3>

In Mathematics, the Angle Addition Postulate states that the measure of an angle formed by two (2) angles that are placed side by side to each other is equal to the sum of the measures of the two (2) angles.

This ultimately implies that, the Angle Addition Postulate can be used to determine the measurement of a missing angle in a geometric figure or it can be used for calculating an angle that is formed by two (2) or more angles such as m∠CBA = m∠ABE + m∠CBD.
