Find the area of the shape below.
m_a_m_a [10]

Answer:

 A_{shape}=A_{triangle}+A_{square}\\\\A_{shape}=(\frac{bh}{2}+s^2)\ units^2

Step-by-step explanation:

I assume that it is a composed figure formed by a triangle and a square.Since you did not  give the dimensions of the triangle and the dimensions of the square, I will giveyou  a general explanation about how to solve this exercise.

The area of the shape will be the sum of the the area of the square and the area of the triangle.

Then, you need to remember that the area of a triangle can be calculated with the following formula:

A_{triangle}=\frac{bh}{2}

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

And the area of a square can be found with this formula:

A_{square}=s^2

Where "s" is the length of any side of the square.

Therefore, the area of the shape will be

 A_{shape}=A_{triangle}+A_{square}\\\\A_{shape}=(\frac{bh}{2}+s^2)\ units^2

Using elimination method, what will be the value of y after solving -x - y = 5 and -x + 4y = 15?
natka813 [3]

9514 1404 393

Answer:

  y = 2

Step-by-step explanation:

The variable x can be eliminated by subtracting the first equation from the second.

  (-x +4y) -(-x -y) = (15) -(5)

  5y = 10 . . . . . . . simplify

  y = 2 . . . . . . . . . divide by 5

A cone has a base area of 420mm and height of 180mm. What is the volume of the cone.
luda_lava [24]

Cone Volume = PI * radius^2 * height / 3, which can br rewritten as

Cone Volume = base area * height / 3

Cone Volume = 420mm * 60

Cone Volume = 25,200 cubic mm
