. 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 $2.5$
