Answer:

<u>30 gallons solution 4% and 10 gallons solution 8%</u>

Step-by-step explanation:

<h3>x•4%+y•8%=40•5% </h3>

<em><u>4x+8y=40•5 and x+y=40</u></em>

x=40-y

4(40-y)+8y=200

160-4y+8y=200

4y=200-160

4y=40 => y=10 (gallons solution 8%)

=> x=40-10=30 (gallons solution 4%)

30 gallons solution 4% and 10 gallons solution 8%

Let's first take a look at function G. From the first to second row, the x-value increases by 2, and the y-value increases by 8.

Thus, function G has a rate of change of 8/2, or 4.

In function H, there is a "2" before the "x", which means function H has a rate of change of 2.

Thus, the statement that is true is:

  • Function G has a rate of change of 4, and function H has a rate of change of 2

Let me know if you need any clarifications, thanks!

Answer:

864 squared meters

Step-by-step explanation:

Set up a proportion.  The scale between 270 and 360 should be the same as 648 to the fourth yard.

\frac{270}{360} = \frac{648}{x}\\270x = (360)(648)\\270x = 233280\\x = 864 m^2
