Step-by-step explanation:
we know that
If two rectangles are similar, then the ratio of its corresponding sides is proportional
step 1
Find the length of the new rectangle
Let
L-----> the length of the new rectangle
step 2
Find the area of the new rectangle
we know that
The area of the rectangle is
we have
substitute
Answer:
6
Step-by-step explanation:
First distribute
4 times -2 = -8
4 times -4 = -16
12(-8/-16)
-8/-16 = 0.5
so 12(0.5) = 6
Depends on where you are in the math book but this would be the most simple way.
n= number
sqar(-1) = i

Answer:
35 m/s
Step-by-step explanation:
Let gravitational acceleration g = 9.8m/s2. We can calculate the amount of time for the ball to fall vertically a distance of 1.6 m
This is also the time it takes for the ball to fly horizontally, assume constant horizontal speed, we can calculate the speed it takes to travel across 20m in 0.571s
v = 20 / 0.571 = 35 m/s
