Answer:

We will need about 3.3 gallons of red paint.

Step-by-step explanation:

Let

  • r = amount of red paint
  • w = amount of white paint

The amount of red paint is half the amount of white paint.

r = 1/2 w

w = 2r [1]

We need to make a total of 10 gallons. Then,

r + w = 10 [2]

Replacing [1] in [2]

r + (2r) = 10

3r = 10

r = 3.3

We will need about 3.3 gallons of red paint.

Answer:

D

Step-by-step explanation:

The diagram is attached.

Looking at the diagram, we want the side "opposite" of the angle given and the side "adjacent" is given.

Which ratio relates opposite and adjacent? It is Tan.

We can use trigonometry and tan ratio to solve for the distance "x":

Tan(84)=\frac{x}{650}\\x=Tan(84)*650\\x=6184.4

D is the correct answer.
