-2×-y=3-9×-y=17

=2×+9×=1y+1y=17+3

11×=2y=20

11=y=20÷2

11y=10

y=10/11

The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net exports a
harina [27]

Answer:

$80 billion

Step-by-step explanation:

From the graph, we have the following:

United\ States = -110

Denmark = -30

China = 120

Germany = 40

Spain = 30

Required

Determine the difference in US and Denmark exports

The difference is calculated as thus:

Difference = Denmark - United\ States

This gives:

Difference = -30 - (-110)

Difference = -30 +110

Difference = 80

<em>Hence, the difference is $80 billion</em>

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.
