Find the surface area of the net below.
dedylja [7]

Answer:

472 in²

Step-by-step explanation:

This net is made up of 3 identical rectangles and 2 identical triangles.

Area of a rectangle = width x length

Area of a triangle = 1/2 x base x height

<u>Rectangle</u>

  • width = 8 in
  • length = 19 in

<u>Triangle</u>

  • base = 8 in
  • height = 2 in

<u>Surface Area</u>

SA = 3(8 x 19) + 2(0.5 x 8 x 2)

⇒ SA = 456 + 16

⇒ SA = 472 in²

A baseball player was at bat 473 times during the regular season. If he made a hit 31.5% of the times he was at bat, how many hi
Sauron [17]
So, since the question is asking you what percentage 31.5% is of 473, you can multiply 31.5 by 473 and get <span>14899.5. But, you'll have to change this answer into a percentage. So, you can move the decimal point two places over, and end up with 148.995. Since the question says that you can round to the nearest whole number, you can go ahead and put down 149. Hope this helped.</span>

bulgar [2K]
For a parallelogram, we know that there are to pairs of angles that are the same and that all 4 angles add to 360.

2(5x-2)+2(48)=360
2(5x-2)+96=360
10x-4+96=360
10x+92=360
10x=268
x=26.8

Final answer: x=26.8

Hope this helps!
