3.	Two cyclists start from the same point of a mountain. One travels 1500 m downward the mountain in15 minutes where the other travels 250 m upward the mountain in the same time. How far are theyfrom each other after 15 minutes?
Answer» Answer: Given : Distance travelled by 1st CYCLIST in 20 mins = 1200 m Distance travelled by 2nd cyclist in 20 mins = 350 m To Find : How far are the 2 cyclists from each other after 20 mins =? SOLUTION : Since they have both started from the same point and are moving in opposite directions. Lets assume the downward direction to be positive and UPWARD direction to be negative : So, distance travelled by the 1st cyclist = + 1200 m And distance travelled by the 2nd cyclist = - 350 m So, the GAP between them will be = 1200 + (- 350 ) = 1200 - 350 m =850 m So, after 20 mins they are 850 m far from each other . Step-by-step explanation:

Two cyclists start from the same point of a mountain. One travels 1500 m downward the mountain in15 minutes where the other travels 250 m upward the mountain in the same time. How far are theyfrom each other after 15 minutes?

Answer»

Answer:

Given :

Distance travelled by 1st CYCLIST in 20 mins = 1200 m

Distance travelled by 2nd cyclist in 20 mins = 350 m

To Find :

How far are the 2 cyclists from each other after 20 mins =?

SOLUTION :

Since they have both started from the same point and are moving in opposite directions.

Lets assume the downward direction to be positive and UPWARD direction to be negative :

So, distance travelled by the 1st cyclist = + 1200 m

And distance travelled by the 2nd cyclist = - 350 m

So, the GAP between them will be = 1200 + (- 350 )

= 1200 - 350 m

=850 m

So, after 20 mins they are 850 m far from each other .

Answer»

Answer:80degree

Step-by-step explanation:as, l//m and n is transversal

ANGLE 5 = angle 1 ( CORRESPONDING angles)

( 2x+ 40)=(3x+20)

= 2x+40= 3x+20

= 2x-3x = 20-40

= -x = -20

= x=20

134 + 2x-10 = 360.

2x-10 = 360 - 134.

2x-10 = 226

2x = 226+10

The perimeter of a triangle is 8+13a+7a2 and two of its sides are 2a2 +3a+ 2 and 3a2 – 4a-1.Find the third side of the triangle.

Answer»

Step-by-step EXPLANATION:

The perimeter of a triangle is 8+13a+7a2

two of its sides are 2a2 +3a+ 2 and 3a2 – 4A-1.

Two sides of triangle are given, LET the non given side be x

Perimeter of triangle = sum of all sides

(2a2 +3a+ 2) + (3a2 – 4a-1) + x = 8+13a+7a2

(4a +3a + 2) +(6a - 4a - 1) + x =8+13a+14a

x = 7 + 18a

Third side of triangle is 7 + 18a

Let the other diagonal be 2X (x)²+ (20)² = 25²⇒x² = 625−400 x² = 225² x = 15cm Other diagonal = 2x = 2×15 = 30cm Then, area of rhombus = Diagonal × Diagonal = 15×30 = 600cm²

Answer»

Answer : 600 cm²

Explanation :

perimeter of a rhombus is 100 cm (given)

one of the diagonals is 40 cm (given)

We NEED to find the area of rhombus.

all sides of a rhombus are equal.

SIDE of rhombus = 100/4 =25cm

the diagonal of rhombus BISECT each other.

Let the other diagonal be 2X

(x)²+ (20)² = 25²⇒x² = 625−400

x² = 225²

x = 15cm

Other diagonal = 2x

= 2×15

= 30cm

Then, area of rhombus = Diagonal × Diagonal

= 15×30

= 600cm²

Answer»

Answer:

Time TAKEN = 2t² + 3t + 4 hr if Distance = 2t⁴ + 3t³ - 2t² - 9t - 12 km & Speed = t² - 3 km/hr

Step-by-step explanation:

Distance = 2t⁴ + 3t³ - 2t² - 9t - 12 km

Speed = t² - 3 km/hr

Time Taken = Distance / Speed

Time Taken = (2t⁴ + 3t³ - 2t² - 9t - 12)/ (t² - 3 )

2t² + 3t + 4

t² - 3 _|2t⁴ + 3t³ - 2t² - 9t - 12 |_
