Answer: $2.70\ quarts\approx3\ quarts$

Step-by-step explanation:

The area of a rectangle can be calculated with this formula:

$A_r=lw$

Where "l" is the lenght and "w" is the width.

And the area of triangle can be found with this formula:

$A_t=\frac{bh}{2}$

Where "b" is the base and "h" is the height.

First:

- Convert inches to feet:

$(30\ in)(\frac{1\ ft}{12\ in})=2.5\ ft$

- Convert the mixed number to decimal number:

$30\frac{1}{10}=30+0.1=30.1$

You can identify that the ramp is formed by three rectangles and two equal right triangles.

Since the bottom of the ramp does not have to be stained, you need to find:

1. The area of the smaller rectangle:

$A_1=(2.5\ ft)(6\ ft)=15\ ft^2$

2. The area of the larger rectangle on the top:

$A_2=(30.1\ ft)(6\ ft)=180.6\ ft^2$

3. The area of the triangles:

$A_3=A_4=\frac{(30\ ft)(2.5\ ft)}{2}=37.5\ ft^2$

Add the areas:

$Total=15\ ft^2+180.6\ ft^2+37.5\ ft^2+37.5\ ft^2=270.6\ ft^2$

Since a quart of stain covers $100 ft^2$ , for $270.6\ ft^2$ you need to buy:

$\frac{270.6}{100}=2.70\ quarts\approx3\ quarts$

Identify the vertex of the graph. Tell whether it is a minimum or a maximum.

Sedbober [7]

Answer:

Vertex = (-1, 2)

Maximum

Step-by-step explanation:

The middle point of the graph is at x coordinate -1 and the point is at the top while the graph slopes down so it is a maximum point and not a minimum point.
