Answer» ★Given:- The average of 31 results is 60. Average of the FIRST 16 results is 58 Average of last 16 results is 62. ★To find:- The 16th result. ★Solution:- Given , MEAN of 31 results = 60 The total SUM = 31 (60) = 1860 Also given, Mean of first 16 results = 58 So the total sum = 16 (58) = 928 Mean of last 16 results = 62 So the total sum = 16 (62) = 992 Total Sum of the above:- →992+928 →1920 Now, 16th result = total sum of first 16 results + total sum of last 16 results - total sum of 31 results. Putting values, → 928 + 992 - 1860 → 1920 - 1860 → 60 Therefore, the 16th result is 60. __________

The average of 31 results is 60. If the average of the first 16 results is 58 and that of thelast 16 results is 62. find the 16th result.

Answer»

★Given:-

The average of 31 results is 60.
Average of the FIRST 16 results is 58
Average of last 16 results is 62.

★To find:-

The 16th result.

★Solution:-

Given ,

MEAN of 31 results = 60

The total SUM = 31 (60)

= 1860

Also given,

Mean of first 16 results = 58

So the total sum = 16 (58)

= 928

Mean of last 16 results = 62

So the total sum = 16 (62)

= 992

Total Sum of the above:-

→992+928

→1920

Now,

16th result = total sum of first 16 results + total sum of last 16 results - total sum of 31 results.

Putting values,

→ 928 + 992 - 1860

→ 1920 - 1860

→ 60

Therefore, the 16th result is 60.

Answer:

Step by Step Solution

STEP

1

:

Trying to factor by splitting the middle term

1.1 FACTORING A2+8a+15

The first term is, a2 its coefficient is 1 .

The middle term is, +8a its coefficient is 8 .

The last term, "the constant", is +15

Step-1 : Multiply the coefficient of the first term by the constant 1 • 15 = 15

Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .

-15 + -1 = -16

-5 + -3 = -8

-3 + -5 = -8

-1 + -15 = -16

1 + 15 = 16

3 + 5 = 8 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5

a2 + 3a + 5a + 15

Step-4 : Add up the first 2 terms, pulling out like factors :

a • (a+3)

Add up the last 2 terms, pulling out common factors :

5 • (a+3)

Step-5 : Add up the four terms of step 4 :

(a+5) • (a+3)

Which is the DESIRED factorization

Final result :

(a + 5) • (a + 3)

21.	the length of a rectangle is 20m less than twice its breadth if the perimeter of the rectangle is 80m find its dimensions
Answer» GIVEN: The length of a RECTANGLE is 20m LESS than twice its breadth. Perimeter of the rectangle is 80m. ⠀ To find: Dimensions of the rectangle. ⠀ Solution: Let the breadth of the rectangle be b. ⠀ Then, length of the rectangle will be Length = 2b - 20⠀⠀... [1] ⠀ We have perimeter of the rectangle, i.e., 80m. Perimeter of a rectangle is given by ⠀ ★ Perimeter = 2(length + breadth) ⠀ → Perimeter = 80 ⠀ → 2(2b - 20 + b) = 80 ⠀ → 2 × (3b - 20) = 80 ⠀ → 3b - 20 = 40 ⠀ → 3b = 40 + 20 ⠀ → 3b = 60 ⠀ → b = 20 ⠀ Substituting the value of b in [1] ⠀ → Length = 2(20) - 20 → Length = 40 - 20 → Length = 20m ⠀ Hence, Length of the rectangle = 20m Breadth of the rectangle = 20m

21.

the length of a rectangle is 20m less than twice its breadth if the perimeter of the rectangle is 80m find its dimensions

Answer»

GIVEN:

The length of a RECTANGLE is 20m LESS than twice its breadth.
Perimeter of the rectangle is 80m.

⠀

To find:

Dimensions of the rectangle.

⠀

Solution:

Let the breadth of the rectangle be b.

⠀

Then, length of the rectangle will be

Length = 2b - 20⠀⠀... [1]

⠀

We have perimeter of the rectangle, i.e., 80m.

Perimeter of a rectangle is given by

⠀

★ Perimeter = 2(length + breadth)

⠀

→ Perimeter = 80

⠀

→ 2(2b - 20 + b) = 80

⠀

→ 2 × (3b - 20) = 80

⠀

→ 3b - 20 = 40

⠀

→ 3b = 40 + 20

⠀

→ 3b = 60

⠀

→ b = 20

⠀

Substituting the value of b in [1]

⠀

→ Length = 2(20) - 20

→ Length = 40 - 20

→ Length = 20m

⠀

Hence,

Length of the rectangle = 20m
Breadth of the rectangle = 20m

A cuboidal diesel tanker is 200 CM long. 200 CM wide and 40 CM deep. how much litre of diesel can it hold?plz tell fast

Answer»

$\red{\textbf{Answer :- 160 lt}}$

Step-by-step EXPLANATION:

$\red{\textbf{Given :-}}$

$length \: = 200cm$

$breadth \: = 200cm$

$depth \: = 4cm$

$\red{\textbf{To find:-}}$

$how \: much \: litre \: it \: can \: hold.$

$\red{\textbf{So,}}$

$volume \: of \: diesel \: tank \: = 200cm \times 200cm \times 4cm$

$= 16 \times {10}^{4} {cm}^{3}$

$Now,$

$1 {m}^{3} = 10 {m}^{3} lt = {10}^{6} {cm}^{3}$

⇒

$1 {cm}^{3} = 10 ^{3} lt$

$volume \: = 16 \times 10lt$

$= 160 \: lt$

$\red{\textbf{Thus, 160 lt it can hold.}}$

42.	Tony scored 17marks out of 20. His friend Peter scored 40 marks out of 50.Whose performane is better
Answer» Answer: Tony's PERFORMANCE is better. Step-by-step EXPLANATION: Given that: Tony scored 17 marks out of 20. His friend Peter scored 40 marks out of 50. Formula used: TOTAL PERCENT marks OBTAINED = (Obtained marks × 100)/(Total marks) % Finding the total percent marks obtained by Tony: Total percent marks obtained = (17 × 100)/20 % Total percent marks obtained = 1700/20 % Total percent marks obtained = 85 % Finding the total percent marks obtained by Peter: Total percent marks obtained = (40 × 100)/50 % Total percent marks obtained = 4000/50 % Total percent marks obtained = 80 % We get that: Tony's performance is better than Peter as Tony gets 85% marks and Peter gets 80% marks.

Tony scored 17marks out of 20. His friend Peter scored 40 marks out of 50.Whose performane is better

Answer»

Answer:

Tony's PERFORMANCE is better.

Step-by-step EXPLANATION:

Given that:

Tony scored 17 marks out of 20.
His friend Peter scored 40 marks out of 50.

Formula used:

TOTAL PERCENT marks OBTAINED = (Obtained marks × 100)/(Total marks) %

Finding the total percent marks obtained by Tony:

Total percent marks obtained = (17 × 100)/20 %
Total percent marks obtained = 1700/20 %
Total percent marks obtained = 85 %

Finding the total percent marks obtained by Peter:

Total percent marks obtained = (40 × 100)/50 %
Total percent marks obtained = 4000/50 %
Total percent marks obtained = 80 %

We get that:

Tony's performance is better than Peter as Tony gets 85% marks and Peter gets 80% marks.

angle A=angle C and angle B=angle D [opposite ANGLES are EQUAL]

angle A+angle B=180 [sum of the ADJACENT angles]

angle A=angle C

3x+15=2x+35

x=20 degrees

angle A=angle C=75 degress

angle A +angle B=180 degrees
