7.7 cm Because the sides of similar figures are in direct proportion to each other
Answer: t= 460.52 minutes
Step-by-step explanation:Q'=Q/100
Q'= rate in and out of water
Finding the differential equation
Let Q'(t)= The quantity of dye in the tank for t time
But rate in=0 Q/200 ×2=Q'
Q'/Q=-1/100
Dividing by Q gives
Ln/Q/ + c = -1/100 + c1
Integrating both sides gives
Ln/Q/ = -(1/100)t + c2
But c+c1=C2= A constant
Q=C2e(-t/100)
200e-(t/100)
t= ln200
t=460.52minutes
It’s the first answer
He can’t just decided what x is he has to solve for it
Product means to multiple so I think it's rs
ABCD is a rectangle so the diagonals are equal
AC = BD
3(x - 2) = x + 18
3x - 6 = x + 18
2x = 24
x = 12
AC = 3(x - 2) = 3(12 - 2) = 3(10) = 30
BD = x + 18 = 12 + 18 = 30
Answer
AC = BD = 30
