HOPE THAT MAY HELP YOU :)
Step-by-step explanation:
Equal groups are illustrations of using the same variable.
A word problem that uses equal group is:
Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled
The only condition for equal groups is that:
The units or variable must be the same
For instance:
Add 5 miles and 4 miles ----- This represents distance
Remove 2 liters from 7 liters --- This represents volume
Add 5 hours and quarter of an hour -- This represents time
And so on.
Answer:
128 ft / second.
Step-by-step explanation:
It's acceleration is due to gravity and is 32 ft s^-2.
To find the velocity when it hits the ground we use the equation of motion
v^2 = u^2 + 2gs where u = initial velocity, g = acceleration , s = distance.
v^2 = 0^2 + 2 * 32 * 256
v^2 = 16384
v = 128 ft s^-1.
Answer:
Step-by-step explanation:
AC² = AD² + DB ²
25 = AD² + 9
AD²= 25 - 9
AD² = 16
AD = 4
Area = 4*3 /2
= 6cm
