The triangle <span>pyramid</span>  is made up of 4 triangles.

------------------------------------
Formula:
------------------------------------
Area of triangle = 1/2 x base x height

------------------------------------
Area of the bottom triangle:
------------------------------------
Area = 1/2 x 9 x 7.8
Area = 35.1 yd²

------------------------------------
Area of the 3 side triangles:
------------------------------------
Area = 3 [ 1/2 x 9 x 10 ]
Area = 135 yd²

------------------------------------
Total Area:
------------------------------------
Total Area = 135 + 35.1 
Total Area = 170.1 yd²

------------------------------------------------------------------------
Answer: Surface Area = 170.1 yd².
------------------------------------------------------------------------

The kind of transformation the quadrilateral underwent is 180° rotation about the origin and the new vertex of Q is (4,5).

<h3>What is transformation of plane shapes?</h3>

Transformation is the change in the coordinates of the vertices that make up a plane shape.

This can be done either by translation, reflection or rotation.

Analysis:

since the x and y coordinates of P is the opposite of the coordinates of p' then there is a 180° rotation about the origin.

If vertex Q is (-4, -5), then Q' is the opposite which is (4, 5 )

In conclusion, the transformation is a 180° rotation and the coordinates of Q' are (4, 5).

Roberto Anaya and his wife plan to rent a condominium for $725 per month. They pay a $125 monthly fee for all of the maintenance
zheka24 [161]

Answer:

$1,149.75

Step-by-step explanation:

We can start this problem off by organizing the monthly and the annual expenses.

<u>Monthly:</u>

$725 - Condominium

$125 - Maintenance Work

<u>Annual:</u>

$468 - Insurance

$129 - Lost Interest

$3,000 - Utility Bills

Since we are solving for the average monthly expense, we should deal with the annual expenses first by dividing them all by 12 since there are 12 months.

x=\frac{(468+129+3000)}{12}

x=\frac{3,597}{12}

x=299.75

Now, we simply add 299.75 to the monthly expenses to get our answer.

x=299.75+725+125

x=1,149.75

The average monthly expense is $1,149.75.
