Answer:
95 ; 105
Step-by-step explanation:
Let :
Aanya's time = x
Krish's time = x + 10
Together = 50
Hence
Aanya's rate = 1/x
Krish's rate = 1/(x + 10)
Together rate = 1/50
Hence,
1/x + 1/(x + 10) = 1 / 50
((x + 10) + x) / x(x + 10) = 1/ 50
(2x + 10)/ x² + 10x = 1/50
50(2x + 10) = x² + 10x
100x + 500 = x² + 10x
x² + 10x - 100x - 500 = 0
x² - 90x - 500 = 0
Using the quadratic equation solver :
x = 95.24 ; x = - 5.24
Time can't be negative
Hence, x = 95 (nearest minute)
It takes Aanya 95 minutes Alone a ND
Krishna (95 + 10) = 105 minutes alone
Answer:
x=9
Step-by-step explanation:
Answer:
10 m
Perimeter = 24 m
Step-by-step explanation:
( Hypotenuse )² = 6² + 8²
= 36 + 64
= 100
= 10 x 10
( Hypotenuse )² = 10²
Hypotenuse = 10 m
Perimeter is the sum of all sides in a triangle.
Perimeter = 6 + 8 + 10 = 24 m
