Answer:  The answer is AB = CD.

Step-by-step explanation: We are given a quadrilateral ABCD with AB ║ CD.

We know that a quadrilateral is said to be a parallelogram if any one of the following conditions is satisfied:

(i)  If both pairs of opposite angles of a quadrilateral are equal, then it is a parallelogram.

(ii) If one pair of opposite sides of a quadrilateral is both equal and parallel, then it is a parallelogram.

(iii) If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.

We are given that AB is parallel to CD, so by the condition (ii), if we get the additional information that AB = CD, then ABCD will be a parallelogram.

Thus, the answer is AB = CD.

2 prime numbers greater than 25 and less than 35
faust18 [17]

Prime numbers greater than 25 and less than 35 is 29 and 31

<em><u>Solution:</u></em>

Prime numbers are whole numbers that are divisible only with 1 and itself

We have to find the prime numbers greater than 25 and less than 35

List out the whole numbers between 25 and 35

26, 27, 28, 29, 30, 31, 32, 33, 34

In the above list, find the prime numbers

Factors of 26 = 1, 2, 13, 26

Factors of 27 = 1, 3, 9, 27

Factors of 28 = 1, 2, 4, 7, 14, 28

<h3>Factors of 29 = 1, 29</h3>

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30

<h3>Factors of 31 = 1, 31</h3>

Factors of 32 = 1, 2, 4, 8, 16, 32

Factors of 33 = 1, 3, 11, 33

Factors of 34 = 1, 2, 17, 34

Here, 29 and 31 are the numbers that are divisible only by 1 and by itself

Therefore, prime numbers greater than 25 and less than 35 is 29 and 31

Maria is using a coordinate plane with the axes labeled only with integers. She says that the point (−0.5, 2) cannot be plotted
vodka [1.7K]

Answer:

Integers ={Positive Natuaral Number +Natural numbers having negative sign behind it+Zero}

      ={------,-3,-2,-1,0,1,2,3,..........}

→Points marked on the X and Y axis on the Coordinate Plane=Integers only

→Point to be marked on the coordinate plane =(-0.5,2)

→As, points on both X and Y axis are integers only.To mark, -0.5 , mark a line between , 0 and -1,that will be ,-0.5.

→You can mark , any terminating decimal on the number line, which is marked with integers only.

→Terminating decimals are those decimals having 2^a ,\text{or}5^b, \text{or} 2^a \times 5^b in the denominator of a fraction.

So, to plot any terminating Decimal on the coordinate plane, you have to use property of Rational Numbers ,which is, you can find infinite number of terminating Decimal between two terminating Decimal.

→Mark -0.5 between 0 and -1 on the X axis.Similarly, mark integer 2 on the Y axis.Draw a line parallel to Y axis ,passing from (-0.5,0) and line parallel to X axis passing through (0,2).The intersection of these two lines will be required point (-0.5,2).
