Your answer is J) 4.
We can find this by first finding the area of the old rug by multiplying 8 by 4, which gives us 32 ft².
Then we find the dimensions of the new rug by doubling 8 and 4, to give us 16 and 8, and we can then multiply these to find the area of the new rug which is 128.
Finally, we divide 128 by 32 to find the scale it was multiplied by, and we get 4.
I hope this helps!
Answer: 5 Seconds
Step-by-step explanation: Given the equation of the height expressed ad;
h(t) = - 16t^2 + initial height
Given that initial height = 400feet
h(t) = - 16t^2 + 400
The waste will hit the ground at when h(t) = 0
substitute
0 = - 16t^2 + 400
16t^2 = 400
t² = 400/16
t² = 25
t = √25
t = 5secs
