Answer:

as area of speed time GRAPH GIVE total distance .

KEY point is only that time is given is min in the graph and we have to change it in hour.

so

total distance=area of graph=1/2 ×b×h

=1/2×(20MIN) ×(40 km/HR)

=1/2×(20/60 hr)×(40km/hr)

=20/3 km

now

avg. speed = total distance /time

= (20/3)/ (20/60)

How much time it takes in 4170km and how much time it takes in 7380km and how much time it takes in 26550km with 60km speedfor all the speed is 60km and these are three questions where there is ''and'' there the sum ends like that they are three questions in it

Answer»

This is simple we KNOW that

Distance = speed x time

or

speed = Distance.

Time

or

Time = distance

speed

I) Here the distance is 4170 KM

speed = 60km/ hr

so time

= 4170. = 69.5 = 6.905 hrs

60

2) Here the distance is 7380 km

time = 7380 = 123 = 12.3 hrs

60

3) Here the distance is 26550 Km

time = 26550 = 442. 3 = 44.23 hrs.

Hope it HELPS you

Find the odd man out, among the given number groups. 92432, 48422, 67626, 78428

Answer»

GIVEN,

The given numbers are = 92432, 48422, 67626, 78428

To find,

The odd NUMBER in the given SEQUENCE.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

If we observe the given numbers then we will get that in the three out of four given numbers, the square of the last two digits is exactly equal to the first three digits in the proper sequence.

  1. 48422 » (22)² = 482
  2. 67626 » (26)² = 676
  3. 78428 » (28)² = 784

But, the first number doesn't match the above mentioned criteria.

92432 » (32)² = 1024 ≠ 924

Hence, the odd number is 92432

Find area using heron's formula and height of a triangle

Answer»

Answer:

AREA of traingle:- 1/2*base*height

Step-by-step EXPLANATION:

You can calculate the area of a triangle if you know the lengths of all three sides, using a formula that has been known for NEARLY 2000 years.

It is CALLED "Heron's Formula" after HERO of Alexandria (see below)

Just use this two step process:

Step 1: Calculate "s" (half of the triangles perimeter):

s = a+b+c2

Step 2: Then calculate the Area:

herons formula A = sqrt( s(s-a)(s-b)(s-c) )

a school has 200 students. one third of the boys have blue eyes and one quarter of the girls have blue eyes. given that a total of 57 students have blue eyes how many boys attend the school

Answer»

ANSWER:

let number of boys attend the school be X

HENCE number of girls attend the school =200-X

Number of boys with blue EYES = 1/3×X

= X/3

Number of girls with blue eyes

= 1/4×(200-X)

= 200-X/4

ATC

(X/3) + (200-X/4) = 57

(4X+600-3X/12) = 57

(X+600/12) = 57

(X+600) = 57×12

X = 684 - 600

X = 84

hence number of boys attend the school

= X = 84

Please this question

Answer»

Let the 2 consecutive odd integers be

n and n+2.

n(n + 2) = 99

Solve for n.

n2 + 2n - 99 = 0

(n + 11)(n - 9) = 0 ⇒

TWO solutions:

n = -11

n + 2 = -9

and

n = 9

n + 2 = 11

Test the answers.

OR

Let the two consecutive odd integers be x and x +2

x +2 Given :-

x(x+2) = 99

x² + 2x = 99

x² + 2x - 99 = 0

splitting the middle TERM :-

x² + 11x - 9x - 99 = 0

x( x + 11) - 9(x + 11) =0

(x - 9) ( x + 11) = 0

x = 9 , x = - 11

x = 9 is the value taken here :-

x = 9

x + 2 = 9 + 2 = 11

The no:s would be 9 and 11

Let , Breadth Be X

Length = 2 + 2Breadth

Length = 2 + 2X

Perimeter Of RECTANGLE = 154

******

Perimeter Of rectangle = 2( Length + Breadth )

154 = 2 ( 2 + 2X + X )

154 = 4 + 6X

6X = 150

X = 150 / 6

X = 75 / 3

X = 25 Meter

In a class test , the sum of marks in maths and science is 28 .had he got 4 less marks in maths and 3 more marks in science the product of his marks would have been 180 . find his marks in the two subjects .​

Answer»

\huge{\mathfrak{Solution:-}}

Let the MARKS OBTAINED in MATHEMATICS be 'x' then the marks obtained in science will be 28 - x.

According to question,

\sf{(x+3)(28-x-4)=180}

\sf{\implies (x+3)(24-x)=180}

\sf{\implies 24x-x^{2}+72-3x=180}

\sf{\implies 21x-x^{2}-108=180}

\sf{\implies x^{2}-21x+108=0}

\sf{\implies x^{2}-12x-9x+108=0}

\sf{\implies x(x-12)-9(x-12)=0}

\sf{\implies x=9,12}

The marks obtained is mathematics can be 12 or 9.

If he obtained 12 marks in mathematics then he obtained 28 - 12 = 16 marks in science.

If he obtained 9 marks in mathematics then he obtained 28 - 9 = 19 marks in science.
