ANSWER

For 402

Nearest perfect square is 400

400

= 20

402 − 400 = 2

For 1989

Nearest perfect square is 1936

1936

= 44

1936 − 1989 = 53

For 3250

Nearest perfect square is 3249

3249

= 57

3250 − 3249 = 1

For 825

Nearest perfect square is 784

784

= 28

825 − 784 = 41

For 4000

Nearest perfect square is 3969

3969

= 63

4000 − 3969 = 31

t=14/3

Step-by-step explanation:

3t-2/4-2t+3/3=5/6-t

=3t-2t-2/4+1=5/6-t

=t-2+4/4=5/6-t

=t-6/4=5/6-t

=t+t=5/6+6/4

=2t=10+18/12

=2t=28/12

=t=28/12*2/1

=t=56/12

5) a)The transparent glass can be converted by sticking a frosted sheet on it so as to make it frosted glass.

b) By carving a lot of designs on the glass without leaving any plain space, which makes the glass translucent.

6) A shadow is a black SPOT formed in the opposite direction of the light rays falling on an object. Shadow is formed due to the bending of light rays around the edges of an opaque object THUS forming a sharp black shape same of that of the object, which is basically it's shadow. No MATTER what the colour of the object is, shadows usually are same i.e black. But since white reflects some light back, shadow may be little faded. but no much difference.

7) Image is formed by reflection of light rays after striking a smooth surface. It shows the colour and details of the object whereas shadow is just a black spot resembling the shape of the object and shows no details. How are shadows formed is ALREADY answered by me.

Hope this helped.

Answer:

The required smallest number by which 3645 must be multiplied to get a perfect square is 5.      

Step-by-step EXPLANATION:

To find : The smallest number by which 3645 must be multiplied to get a perfect square?

Solution :

First we FACTOR the 3645

3 | 3645

3 | 1215

3 | 405

3 | 135

3 | 45

3 | 15

5 | 5

  |  1

If we pair of 2, 3 has 3 pairs and 5 is left alone.

So, If 5 is multiplied to the number then the number form is the perfect square.

Multiply both side by 5,

Therefore, The required smallest number by which 3645 must be multiplied to get a perfect square is 5.

Step-by-step EXPLANATION:

ANSWER.....................

Answer:

Remember that we often work with a specific set of objects when solving problems or discussing issues. We called this set of objects a universal set or universe. For example, in the lead-in problem above, the universal set COULD be either the set of all U. S. dollars or the set of the $836 Sam originally had in the checking account.

Complement of a Set: The complement of a set, denoted A', is the set of all ELEMENTS in the given universal set U that are not in A.

In set- builder notation, A' = {x ∈ U : x ∉ A}.

The Venn diagram for the complement of set A is shown below where the shaded region represents A'.

Complement of a set Venn diagram.

Example: For the lead-in example on the previous page, let the universal set U be the $836 Sam originally has in the checking account and let A be the set of the $429 of the check. The complement of set A would be the set of the $407 remaining in the checking account.

Example: Let U = {1, 2, 3, 4, 5, 6} and A = {1, 3, 5}. Then A' = {2, 4, 6}.

Example: U' = ∅ The complement of the universe is the EMPTY set.

Example: ∅' = U The complement of an empty set is the universal set.

Set Difference: The relative complement or set difference of sets A and B, denoted A – B, is the set of all elements in A that are not in B.

In set-builder notation, A – B = {x ∈ U : x ∈ A and x ∉ B}= A ∩ B'.

The Venn diagram for the set difference of sets A and B is shown below where the shaded region represents A – B.

Venn diagram for Set Difference A and B.

Example: For the lead-in example on the previous page, let the universal set U be the set of all U.S. dollars, let set A be the set of $836 Sam originally has in the checking account, and let B be the set of the $429 of the check. Then the set difference of A and B would be the $407 remaining in the checking account.

Example: Let A = {a, b, c, d} and B = {b, d, e}. Then A – B = {a, c} and B – A = {e}.

Example: Let G = {t, a, N} and H = {n, a, t}. Then G – H = ∅.

How should we define the subtraction of whole numbers?

In the lead-in example on an earlier page of this section, the remaining balance was the difference between the cardinalities of the sets for the checking account and the check. This also works for the third example (above)where

n(G) – n(H) = 3 – 3 = 0 = n(∅).

But, with the second example (above) the difference between the cardinalities does not give the expected result, e.g.,

n(A) – n(B) = 4 – 3 = 1 ≠ 2 = n(A – B).
