Area of the rooms:
Room I = 15.9 * 8.6 = 136.74
Room II = 11.9 * 6.3 = 74.97
Hence, the total area is: 211.71 square foot.

Answer:
Question 12: 60°
Question 13: 30°
Question 14: 60°
Question 15: 120°
Step-by-step explanation:
Question 12: The measure of a circle is 360°, so ∠CGD which is 
of a full rotation is 60°.
Question 13: ∠CGH is 
of ∠CGD, so its angle measure is 30°.
Question 14: Since the interior sum of all angles in a triangle is 180° and two angles have measures of 90° and 30°, that means ∠HCG has a measure of 60°.
Question 15: Since ∠EGC is 
of a full rotation, and is twice as great as ∠CGD, that means it has an angle measure of 120°.
<span>7x + 16 < -20 + 25x multiply the right-hand side by 5
16 < -20 + 18x combine like terms on right hand side: 25x - 7x = 18x
36 < 18x combine like terms on left hand side: 16 + 20 = 36
2 divide by 18: 36/18 = 2</span>
Answer:
(10,6)
Step-by-step explanation:
The equation you would use to solve this is (x1+x2/2 , y1+y2/2) so when you plug in the numbers you get this (6+14/2 , 3+9/2) which eventually simplifies into (10, 6)
Answer:
(2, -4).
Step-by-step explanation:
x^2 - 4x
= (x - 2)^2 - 4.
So the vertex is at
(2, -4).
