. Water in a 10 gallon tank is draining at a rate of 2 gallons per hour. Water in a separate tank is filling at a rate of 4 gall
taurus [48]

Answer:

Step-by-step explanation:

Water in a 10 gallon tank is draining at a rate of 2 gallons per hour.

= 10 - 2x

Water in a separate tank is filling at a rate of 4 gallons per hour.

= 10 + 4x

Equating both Equations together

10 - 2x = 10 + 4x

10 - 10 = 4x - 2x

How long until the tanks have the same amount of water?

Let the time = x

Triangle ABC was dilated and translated to form similar triangle A'B'C'.
kompoz [17]

we have that

A(0,2)\ B(2,2)\ C(2,0)\\A'(-4,-1)\ B'(1,-1)\ C'(1,-6)

we know that

Triangles ABC and A'B'C' are similar

Step 1

Find the distance AB and distance A'B' with the formula

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

a) distance AB

dAB=\sqrt{(2-2)^{2}+(2-0)^{2}}

dAB=\sqrt{(0)^{2}+(2)^{2}}

dAB=2\ units

b) distance A'B'

dA'B'=\sqrt{(-1+1)^{2}+(1+4)^{2}}

dA'B'=\sqrt{(0)^{2}+(5)^{2}}

dA'B'=\sqrt{25}\ units

dA'B'=5\ units

Step 2

Find the scale factor

scale\ factor= \frac{measure\ A'B'}{measure\ AB} \\ \\ scale\ factor=\frac{5}{2} \\ \\ scale\ factor=2.5

therefore

the answer is

the scale factor of the dilation is equal to 2.5
