Willyou count 660?YesNo(C) You are counting by tens. You start counting at 249. Willyou count 350?Yes No(d) You are counting back by hundreds. You start at 540. Willyou count 40?YesNo​

Answer»

Given :  Numbers and counting by Different numbers

To find : given  number will come in counting sequence or not

SOLUTION:

counting by hundreds

start counting at 467

=> 467 + 100n      n = 1 , 2 , 3..............

767 = 467 + 100n

=> 300 = 100n

=> n = 3

=> YES  , 767 will be counted

counting by fives

start counting at 635

=> 635 + 5n      n = 1 , 2 , 3..............

660 =  635 + 5n

=>25 = 5n

=> n = 5

=> YES  , 660 will be counted

counting by tens

start counting at 249

=> 249 + 10n      n = 1 , 2 , 3..............

350 = 249 + 10n

=>101 = 10n

=> n = 101/10 = 10.1  ( not an integer)

=> No ,  350 will not be counted

counting back by hundreds.

Start at 540

=> 540 - 100n    n = 1 , 2 , 3..............

=> 40  =540 - 100n

=> -500 = -100n

=> n = 5

YES  , 40 will be counted

1/7 power 4-2x = root 7 find the value of x ​

Answer»

EXPLANATION:-

\frac{1}{{7}^{4 - 2x}} =  \sqrt{7} =  >  {7}^{ - (4 - 2x)} =  {7}^{ \frac{1}{2} } =  >

{7}^{2x - 4} =  {7}^{ \frac{1}{2}} =  > 2x - 4 =  \frac{1}{2} =  >

4x - 8 = 1 =  > 4x = 8 + 1 = 9 =  >

4x = 9 =  > x =  \frac{9}{4}

Solve the following pair of linear equations by the substitution method .​

Answer»

Answer:

Take LCM of 3x/2-5y/3

9x-10y/6= -2

9x-10y=-2×6

9x-10y= -12 _equation 1 ST

Now take LCM of x/3 +y/2

2x+3y/6= 13/6

2x+3y= 13/6×6

2x+3y= 78/6 _ equation 2 ND

By USING substitution METHOD

Now multiple equation 1st by 18 and equation 2 nd by 10 then add equation 1 St and 2 nd

162x -180y= -216

120x+180y=780

__________________

282x = 564

X= 564/282= 2

Put the value of X in equation 1 St

9x -10y = -12

9×2-10y= -12

18-10y=-12

-10y=-12-18

-10y= - 30

y= -30/-10

y= 3

Therefore X= 2 and y= 3

Find the remainder when x³+3x²+1 is divided by x—½ ,x ,x+π​

Answer»

<P>ANSWER:

Answer:X-½=0

Answer:x-½=0 x=½

Answer:x-½=0 x=½ p(x)=x³+3x²+1

Answer:x-½=0 x=½ p(x)=x³+3x²+1 p(½)=( ½)³+3.(½)²+1

Answer:x-½=0 x=½ p(x)=x³+3x²+1 p(½)=( ½)³+3.(½)²+1 =⅛+¾+1

Answer:x-½=0 x=½ p(x)=x³+3x²+1 p(½)=( ½)³+3.(½)²+1 =⅛+¾+1 =15/8

Answer:x-½=0 x=½ p(x)=x³+3x²+1 p(½)=( ½)³+3.(½)²+1 =⅛+¾+1 =15/8x+π=0

Answer:x-½=0 x=½ p(x)=x³+3x²+1 p(½)=( ½)³+3.(½)²+1 =⅛+¾+1 =15/8x+π=0x=π

Answer:x-½=0 x=½ p(x)=x³+3x²+1 p(½)=( ½)³+3.(½)²+1 =⅛+¾+1 =15/8x+π=0x=π π=22/7

Let A & B be 2 sets such thatN(A) = 35 m (A intersectionB)=11 M(A UB)'= 17.n (U) = 57. Find N(B) N(A-B), n (B-A).​

Answer»

Answer:

n(B)=16

n(A-B)=24

n(B-A)=5

Step-by-step EXPLANATION:

n(A)=35

n(A∩B)=11

n(A∪B)'=17

n(U)=57

n(A∪B)'=n(U)-n(A∪B)

17=57-n(A∪B)

n(A∪B)=57-17=40

========================

n(A∪B)=n(A)+n(B)-n(A∩B

40=35+n(B)+11

n(B)=40-35+11=16

=================

n(A-B)=n(A)-n(A∩B)

=35-11

n(A-B)=24

======================

n(B-A)=n(B)-n(A∩B)

=16-11

n(B-A)=5

What is the 38th Sum of an AP series 10,7,4...​

Answer»

ANSWER:

here, a = 10

         d= 7-10

            = -3

        n = 38

        aₙ = a₃₈

now 38 TH term of AP = a₃₈ = a + (n-1) d

                                            =  10 + ( 38 - 1) -3

                                            = 10 + 37(3)

                                            = 10 + 111

                                            = 121

3 less than one fifth of a number is 16​

Answer»

Answer:

19

Step-by-step EXPLANATION:

let the NUMBER be X.

Then, required equation according to the question = X/5 - 3 = 16

=> X - 15 / 5 = 16

=> X - 15 = 16 × 5

=> X - 15 = 80

=> X = 80 + 15

=> X = 95

Then, number = X / 5 = 95/5 = 19
