(Sorry for no step by step)
Answer:
80 liters
Step-by-step explanation:
24 liters is the difference between 2/5 full and 1/5 full.
Let x = number of liters in full tank.
2/5 x - 1/10 x = 24
4/10 x - 1/10 x = 24
3/10 x = 24
1/10 x = 8
x = 80
Answer: 80 liters
Answer:
Option A
Step-by-step explanation:
By applying Pythagoras theorem in ΔABC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
AC² = AB² + BC²
AC² = 6² + 5²
AC = 
Similarly, by applying Pythagoras theorem in ΔACD,
AD² = AC² + CD²
(10)² =
+ x²
x² = 100- 61
x² = 39
x = √(39)
Option A will be the answer.
