Answer» ANSWER: DHONI = 31 runs Saurabh = 62 runs [MARK THE ANSWER AS BRAINLIEST] Step-by-step explanation: Let Dhoni's Score = X Saurabh's Score = 2 × Dhoni's Score ⇒ 2x Total Runs = 7 runs SHORT of century ⇒ 100 - 7 ⇒ 93 According to the question : Saurabh's Score + Dhoni's Score = 93 ⇒ x + 2x = 93 ⇒ 3x = 93 ⇒ x = 93/3 = 31 ∴ Dhoni's Score = 31 Saurabh's Score = 2 × 31 = 62

7.

Saurabh scored twice as many runs as Dhoni. Together their runs fell 7 short of a century. How many runs did they score

Answer»

ANSWER:

DHONI = 31 runs

Saurabh = 62 runs

[MARK THE ANSWER AS BRAINLIEST]

Step-by-step explanation:

Let Dhoni's Score = X

Saurabh's Score = 2 × Dhoni's Score

⇒ 2x

Total Runs = 7 runs SHORT of century

⇒ 100 - 7

⇒ 93

According to the question :

Saurabh's Score + Dhoni's Score = 93

⇒ x + 2x = 93

⇒ 3x = 93

⇒ x = 93/3 = 31

∴ Dhoni's Score = 31

Saurabh's Score = 2 × 31 = 62

FACTS ABOUT STUDYPlaying scary and violent video games help children master their fears in real life.Video games can lessen disruptive behaviors and enhance positive development in ADHD childrenPractical work in science provides children little or no learning at allChess makes kids smartGardening improves children’s desire to learn and boosts their confidenceKids who garden show a better ability to concentrate.Gardening helped use up surplus energy in active kids.The process of growing something from seed to fruit helps teach children responsibility and managing a living organism.Some students learned valuable math skills as they sold their produce to the town for a profit.Getting in touch with the dirt and bugs, helped some young students overcome their fears.An English teacher found her student’s creativity in poetry expanded after working in the garden.Playing with blocks increases neuron count in childrenTeaching kids at a very early age is counterproductive to their learningChildren are not blank slates on which adults imprint knowledgeChildren’s brains are far more powerful and intuitive than we ever imagined. As more and more research is done on the impact of early education on children, the results continue to point to a surprising conclusion; when children are given a rich environment to explore, they naturally use scientific processes to discover the world around them.Alison Gopnik, professor at the University of California, reported this in her research that was outlined in the September issues EdWeek’s blog. The push for more academics, more structure, and more early academic intervention is not necessarily beneficial. Adults are not the “givers” of information, but rather facilitators that allow children to use their natural curiosity to discover the world. It would seem that one of the best predictors of future academic success is built on this foundation.

Again travelled 110 km to the WEST from there. • To Find:- Total distance between the car and Patna. • Solution:- Let the starting point be A. After travelling 70 km let that point be B Final point after travelling 110 km be C Diagram:- $\setlength{\unitlength}{1cm}\begin{picture}\thicklines\put(1,1){\line(1,0){4.5}}\put(1,1){\line(0,1){3.5}}\qbezier(1,4.5)(1,4.5)(5.5,1)\put(.1,2.5){\large\bf 110}\put(2.8,.3){\large\bf 70}\put(.7,4.8){\large\bf C}\put(.8,.3){\large\bf B}\put(5.8,.3){\large\bf A}\end{pictue}$ Hence, The distance formed is a right angle Traingle Therefore, Using Pythagoras theorem:- (CA)² = (CB)² + (BA)² → (CA)² = (110)² + (70)² → (CA)² = 12100 + 4900 → (CA)² = 17000 → CA = √17000 → CA = 130.38 Therefore, the distance between the final point and the starting point is 130.38 km.

A car travelled 70 km to the East of Patna and then110 km to the West from there. How far from Patnawas the car finally ?

Answer»

Answer:-

$\red{\bigstar}$ Distance between Patna and final point of car $\large\leadsto\boxed{\rm\purple{130.28 \: km}}$

• GIVEN:-

Car TRAVELLED 70 km to East of Patna.

Again travelled 110 km to the WEST from there.

• To Find:-

Total distance between the car and Patna.

• Solution:-

Let the starting point be A.

After travelling 70 km let that point be B

Final point after travelling 110 km be C

Diagram:-

$\setlength{\unitlength}{1cm}\begin{picture}\thicklines\put(1,1){\line(1,0){4.5}}\put(1,1){\line(0,1){3.5}}\qbezier(1,4.5)(1,4.5)(5.5,1)\put(.1,2.5){\large\bf 110}\put(2.8,.3){\large\bf 70}\put(.7,4.8){\large\bf C}\put(.8,.3){\large\bf B}\put(5.8,.3){\large\bf A}\end{pictue}$

Hence,

The distance formed is a right angle Traingle

Therefore,

Using Pythagoras theorem:-

(CA)² = (CB)² + (BA)²

→ (CA)² = (110)² + (70)²

→ (CA)² = 12100 + 4900

→ (CA)² = 17000

→ CA = √17000

→ CA = 130.38

Therefore, the distance between the final point and the starting point is 130.38 km.

A window has the shape of a rectangle surmounted by an equilateral triangle. If the perimeterof the window is 12 m , find the dimension of the rectangle that will produce the largest area ofthe window.

Answer»

Answer:

if the dimensions are equal , it will form larger area.

Step-by-step EXPLANATION:

we know , perimeter of rectangle = 2(L+B)

so the L+B = 6 ( => 2(l+b) = 12 , l+b = 6 )

therefore, the possible NUMBERS to form this are :-

i) 1+5

ii) 2+4

iii) 3+3

therefore, the area by these ↑ sides are :-

i) 5m²

ii) 8m²

iii) 9m²

therefore, if the LENGTH and breadth of that rectangle is 3×3 m² , then it will form the largest possible area .

Answer» Answer: 12. The length of the EDGE of the cube is 9 cm. 13. The NUMBERS are 2x14 = 28, 3x14 = 42, and 4x14 = 56. Step-by-step explanation: 12. LET's assume that, the length of the edge of the cube is x. ∴ $x^3$ = 729 = 3.3.3.3.3.3 = $3^3.3^3$ $=9^3$ ∴ $x = 9 cm$ 13. Three numbers are in the ratio 2:3:4 If the first number is 2x, then the other two are 3X and 4x According to the problem: $(2x)^3 + (3x)^3 + (4x)^3$ = 271656 $=>8x^3 + 27x^3 + 64x^3$ = 2.2.2.3.3.11.7.7.7 $=>99x^3$ = 99.2.2.2.7.7.7 $=> x^3 = 2^3.7^3$ ∴ $x = 14$ ∴ The numbers are 2x14 = 28, 3x14 = 42, and 4x14 = 56.

12. What is the length of the edge of a cube whose volume is 729 cm"?13. Three numbers are in the ratio 2:3:4. The sum of their cubes is 271656. Find thnumbers.

Answer»

Answer:

12. The length of the EDGE of the cube is 9 cm.

13. The NUMBERS are 2x14 = 28,

3x14 = 42, and

4x14 = 56.

Step-by-step explanation:

12. LET's assume that, the length of the edge of the cube is x.

∴ $x^3$ = 729 = 3.3.3.3.3.3 = $3^3.3^3$ $=9^3$

∴ $x = 9 cm$

13. Three numbers are in the ratio 2:3:4

If the first number is 2x, then the other two are 3X and 4x

According to the problem:

$(2x)^3 + (3x)^3 + (4x)^3$ = 271656

$=>8x^3 + 27x^3 + 64x^3$ = 2.2.2.3.3.11.7.7.7

$=>99x^3$ = 99.2.2.2.7.7.7

$=> x^3 = 2^3.7^3$

∴ $x = 14$

∴ The numbers are 2x14 = 28,

3x14 = 42, and

4x14 = 56.

50.	The measures of angles of quadrilateral are m the ratijo 2 3 6 7 Find the measure of cach of the angles of the quadrilateral .please answer fast
Answer» Answer: In a quadrilateral, the MEASURES of the ANGLES are in the ratio of 2:3:4:6. How do you find the MEASURE of the largest angle? Add 2+3+4+6 = 15. The sum of the angles of a quadrilateral = 360 = 2x+3x+4x+6x where 15x = 360, or x = 360/15 = 24. Hence the four angles of the quadrilateral are 2x = 2x24 = 48 degrees 3x = 3x24 = 72 degrees 4x = 4x24 = 96 degrees 5x = 6x24 = 144 degrees The largest angle is therefore 144 degrees.

Answer»

Answer:

In a quadrilateral, the MEASURES of the ANGLES are in the ratio of 2:3:4:6. How do you find the MEASURE of the largest angle?

Add 2+3+4+6 = 15.

The sum of the angles of a quadrilateral = 360 = 2x+3x+4x+6x

where 15x = 360, or

x = 360/15 = 24.

Hence the four angles of the quadrilateral are

2x = 2x24 = 48 degrees

3x = 3x24 = 72 degrees

4x = 4x24 = 96 degrees

5x = 6x24 = 144 degrees

The largest angle is therefore 144 degrees.
