Answer:
60years
Step-by-step explanation:
let Ben age = x
ishaan age = y
Ben is 4 times old as ishaan:
x=4y ..........equation (1)
6 years ago
Ben age = x-6
Ishaan age = y-6
x-6=6(y-6)
x-6=6y-36
x=6y-36+6
x=6y-30..........equation (2)
equating equation(1) and (2)
4y=6y-30
4y-6y=-30
-2y=-30
y=-30/-2=15
substituting the value of y into equation (1)
x=4y
=4*15
=60
Ben age now =60years
Answer:
Shouldn't there be a picture if we're told to reference the model?

Step-by-step explanation:
Answer:
3.63 meter/sec²
Step-by-step explanation:
When a rock fall from a height h with initial velocity u and the rock reaches the surface in t seconds the expression that represents this is
h = 4t +
gt²
Where g is the acceleration due to gravity
Here h = 0.72 meters
u = 0
t = 0.63 seconds
from the given formula
0.72 = 0 ×(0.63) +
g(0.63)²
0.72 =
g(0.63)²
g = 
= 3.63 meter/sec²
