Answer:
20 gallons
Step-by-step explanation:
The living room is made up of white trim and blue surface area between the walls. Since the ratio of the blue surface area between the walls to the white trim is given by 1 : 10.
Also 2 gallons of blue paints are used for the walls, let x represent the number of white paint used in gallons. Hence:
number of white paint in gallons = [1 / (1 + 10)] * total number of paints = 1 / 11 * total number of paints
2 = 1/11 * total number of paints used
total number of paints = 22 gallons
number of white paint (x) = [10 / (1 + 10)] * total number of paints = 1 / 11 * total number of paints
x = 10/11 * 22
x = 20 gallons
Therefore 20 gallons of white paint was used
Answer:

Step-by-step explanation:
Given two non zero vectors,
.
Let the angle between the two vectors = 
Given that:

Let us have a look at the formula for magnitude of addition of two vectors:

Where
is the angle between the two vectors.
formula for magnitude of subtraction of two vectors:

As per the given condition:

Squaring both sides:

So, the angle between the two vectors is: 
Answer:
a = 6
Step-by-step explanation:
Given
+ 4 = 6 ( subtract 4 from both sides )
= 2 ( multiply both sides by 3 to clear the fraction )
a = 6
You can solve this equation by rearranging the 2x to the opposite side, but since it's a positive, you must change it to a negative. If the number was negative, it would've been a positive.
y=-2x+3
-2x is the slope and 3 is the y-intercept.
