Looking at the data it looks like a line. So the answer will be in y+mx+b format.

Knowing it is a line eliminates answers b and c.
looking at options a is says it starts at about .1 when x is zero. We can see this looks pretty close as the left-most dot is below 1 already.

The slope on a is 1/2--> increasing 1 vertically for every 2 horizontally. The pattern mostly follows that rule.

Therefore a (y=1/2x+.1) would be the correct answer

Carol is going to make a wooden pyramid and then paint it. She drew the net of a square pyramid as shown below to help her plan
rodikova [14]

The given pyramid's total surface area is 3. 24.0 square feet.

Step-by-step explanation:

Step 1:

To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.

There are 3 triangles and 1 square in the figure.

Step 2:

All the triangles are similar.

The surface area of a triangle = \frac{1}{2} (baselength)(height).

The similar triangles have a base length of 3 feet and a height of 2.5 feet.

The surface area of 1 similar triangle = \frac{1}{2} (3)(2.5)= 3.75 square feet.

The surface area for all the similar triangles = 3.75 (4) = 15 square feet.

Step 3:

The surface area of a square is the square of its side length. The square has a side length of 3 feet.

The surface area of the square = a^{2} = 3^{2} =9 square feet.

Step 4:

To calculate the total surface area we sum up all the individual surface area.

The total surface area = 15 + 9 = 24 square feet which is the third option.

How much grain can this container hold?
ludmilkaskok [199]

Answer:

953.78 in^3 of grain.

Step-by-step explanation:

The volume of a cylinder = π r^2 h.

For this cylinder r =  radius of the base = 9/2

= 4.5 in  and the height h = 15 in

So the volume is 3.14 * 4.5^2 * 15

= 953.78 in^3.
