You would need to know how many centimeters the base of the fountain on the blueprint is first. It seems like you are missing some information on this problem.
I'll give you an example anyways.
Let's say the base on the blueprint is 36 centimeters.
1 cm= approximately 0.03 feet
0.03* 36= about 1.08 feet.

Answer: -2.8
Step-by-step explanation:
3t-(8/5) * 4-t < -7
(15t-8)/5 * 4-t < -7
((15t-8)(4-t))/5 < -7
(15t^2)-28t-32< -7
(15t^2)-28t-32-7< 0
(15t^2)-28t-39< 0
Using the quadratic/almighty formula
t= (-b +- ((b^2)-4ac)^(1/2)/2a)
a=15, b=-28, c=-39
t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))
t= -2.8 or t= 0.9
Since
t<0, then t= -2.8
X=16 put 5 in the place of Y Then solve for X
5=1/2x-3 add three on both sides
8=1/2x multiply 2 on both sides
16=x
x=16 And thats your answer
