Answer:
240 gallons
Step-by-step explanation:
Let's set up an ratio where g = gallons and m = miles:
20g = 300m
We need the right side of that to be 3600, so multiply both sides by 12:
12(20g) = 12(300m)
Answer: 240 gallons for 3600 miles
Answer:
the answer is C. 100°
Step-by-step explanation:
The known angle is supplementary with angle A (Look at the attachment), that means that the sum of the known angle and A is 180°, therefore the value of angle A is 80°
then A and B are corresponding angles, which means that they have the same value, that happens because <em>p</em> and <em>q</em> are parallels and both cut line <em>n</em> in the same way. the value of the angles B is 80° too.
Angles B and C are corresponding too, so the value of the angle C is 80°.
Finally angles C and X are supplementary too for which the sum of X and C (80°) is 180°, <em>so the value of X is 100°</em>
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
<u> So c= -9</u>
