The answer is e. all of these because a square has all four sides the same length and has 90 degree angles and rectangles and rhombuses can be squares. And all of these shapes are parallelograms

Mrs. Bendit’s 1st Block class has 28 students. There are 7 girls in the class. What percent of boys are in the class?
Gemiola [76]

Answer:

Boys: 75%

Girls: 25%

Step-by-step explanation:

Total: 28 Students: 100%

7 Girls in clas

28(total)-7 (girls)= 21 Boys in class

__________________

If we divide the amount  boys OR girls ( depending on which gender) after the toal and move the decimal to the right twice after dividing) we will get our answer.

Formula:

(Amount of Boy or girls) = x

X/28

So since we are trying to get the percentages of boys, we will replace X with the amount of boys

21/28 = .75 ( then move the decimal to the right TWICE) =  75  

Then you should get your percentages: 75%  Also if your lookings for girls percentages, you basically subtract 75 ( boys percentages) with the total percentages ( 100) then you should get your answer for the girls: 25%

In the figure, and bisect each other. Complete the statements to prove that quadrilateral ABCD is a parallelogram.
Alisiya [41]

Observe the figure below.

    Statement                                                                          Reason

1. AC and BD bisect each other                                             Given

2. AE = EC and BE = ED                                                         Definition of bisection

3. m \angle AEB = m \angle CED                       Vertical angle theorem

Vertical angle theorem states " When two lines intersect each other, the vertically opposite angles are always equal".

4. \Delta ABE \cong \Delta CDE                         SAS criterion for congruence

5. m \angle ACD = m \angle CAB           Corresponding angles of congruent triangles are congruent

6. AB \parallel CD                                 Converse of alternate interior angle theorem

7.  m \angle BEC = m \angle AED                   Vertical angle theorem

8.  \Delta BEC \cong \Delta DEA            SAS criterion for congruence

9.  BC \parallel AD                                 Converse of alternate interior angle theorem

As, \Delta BEC \cong \Delta DEA, so m \angle CBD = m \angle BDA as corresponding parts of corresponding triangles are equal. As these angles are alternate interior angles, so the lines BC and AD are parallel by  "Converse of alternate interior angle theorem".
