What is the length of AA' , rounded to the nearest hundredth? Type a numerical answer is the space provided. Do not type spaces
inna [77]
Coordinate of A are (0,0)
Coordinates of A' are (5,2)

We can find the distance from A to A' using the distance formula:

AA'= \sqrt{(5-0)^{2}+ (2-0)^{2}  } \\  \\ &#10;AA'= \sqrt{25+4} \\  \\ &#10;AA'= \sqrt{29} \\  \\ &#10;AA'=5.39

Thus, rounded to nearest hundredth, AA' is equal to 5.39

Help with all of these please explain if u can !
sveticcg [70]

Answer:

1. 78cm^2

2. 200 ft^2

Step-by-step explanation:

1. i always cut these complex shapes into simpler ones (in this case a rectangle and a triangle)

the rectangles area is 6*8 or 48 and the triangles area is (10*6)/2 or 30 you then add the two areas to get the area for the whole shape 48+30=78

2. once again you're going to break this shape up into the individual rooms and then add them together the garage is a 4*6 room (24) the bedroom is a 8*4 room (32) the living room is a 10*10 room (100) the kitchens a  6*6 room (36) and the bathroom is a 4*2 room (8) you then add all these together

24+32+100+36+8=200

What is the area of the right triangle shown?
prisoha [69]
The 30:60:90 proportion is 1:sqrt 3: 2

So,

x = 10/2
x = 5

y = 10/sqrt 3

Finding the area:

1/2 * 5 * 10/sqrt 3
25/sqrt 3

Hope this helps!
