Answer:

rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.

Answer:

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.

What is the area of the square adjacent to the third side of the triangle?
Naddik [55]

Answer:

85 units^2 = Area of Blue Square

and

x = 5 units

Step-by-step explanation:

To do this we use the Pythagorean theorem (a^2 + b^2 = c^2). a and b represent the legs of the triangle whereas c represents the longest side of the triangle, or the hypotenuse.

Since we know the area of a square is the side length multiplied by itself (or the side length squared), \sqrt{35} is the side length of the pink square and \sqrt{50} is the side length of the green square.

That means a = \sqrt{35} and b = \sqrt{50} , so...

(\sqrt{35} )^{2} + (\sqrt{50})^{2}  = c^{2}

35 + 50 = c^2

85 = c^2

\sqrt{85} = c

Now we need to square the square root of 85 to find the area of the blue square.

(\sqrt{85})^{2}  = Area of blue square

85 units^2 = Area of Blue Square

To solve the other question we use the same formula again.

x^2 + 12^2 = 13^2\\x^2 +144 = 169\\-144\\x^2 =  25\\x=\sqrt{25} \\x=5

x = 5 units

1. The pollution level in the center of a city at 6 am is 30 parts per million and it
Nady [450]

Answer:

a) y(t) = 30 + 25t

b) The pollution level at 4 o'clock in the afternoon​ is of 280 parts per million.

Step-by-step explanation:

The pollution level in the center of a city at 6 am is 30 parts per million and it grows in linear fashion by 25 parts per million every hour.

This means that the pollution in t hours after 6 am is given by:

y(t) = 30 + 25t, which is the answer to question a.

b. The pollution level at 4 o'clock in the afternoon​

4 in the afternoon is 10 hours after 6 am, so this is y(10).

y(10) = 30 + 25*10 = 30 + 250 = 280

The pollution level at 4 o'clock in the afternoon​ is of 280 parts per million.

Please Determine the value of the number being described. When 10 is subtracted from 3 times the number, what is the result if t
hjlf

Answer:

x = 20/3

Step-by-step explanation:

When 10 is subtracted from 3 times the number and the number is divided by 2, what is the number?     --->        3 ( x / 2) - 10 = 0

3 ( x / 2) - 10 = 0

      3( x / 2 ) = 10

          3x / 2 = 10

               3x = 10 * 2

               3x = 20

                 x = 20/3
