Answer:

27 units squared

Step-by-step explanation:

First, we find the surface area of one of the triangles.

(3*3*0.5)

4.5

Next, we find the surface area of all of the triangles.

(4.5*4)

18

The next step is to find the surface area of the square.

(3*3)

9

The last step is to add the surface areas of the square and triangles together.

(18+9)

27

The surface area of the entire shape is going to be 27 units squared.

amiee wants to order DVDs from amazon each DVD costs 8.49 and shipping for the entire order is 5 dollars she only has 70 dollars
Neporo4naja [7]
You can only get 7 because you could get 8 of them but you need to remember that shipping is 5 dollars. 70/8.49 is 8.24499411 but it would be 7 dvds.

If the supplement of an angle is two-third of itself ,then its supplement is
stich3 [128]
( 'x' is not 144 .)
 
The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .

180 - x = 2/3 x

Multiply each side by 3 :
( Note:  3 x 180 = 540 .)

540 - 3x = 2x

Add 3x to each side:

540 = 5x

Divide each side by 5 :

<u>x = 108°</u> .

Which transformations are needed to change the parent some function to the sine function below?
Harrizon [31]
Beginning with the function y = sin x, which would have range from -1 to 1 and period of 2pi:
Vertical compression of 1/2 compresses the range from -1/2 to 1/2
Phase shift of pi/2 to the left
Horizontal stretch to a period of 4pi, as the crests are at -4pi, 0, 4pi
Vertical shift of 1 unit up moves the range to 1/2 to 3/2
So the first choice looks like a good answer.
