Asquare poster has a side length of 26 in. drawn on the poster are four identical triangles. each triangle has a base of 8 in. and a height of 8 in. children play a game in which they each wear a blindfold and throw a dart at the poster. a player whose dart lands inside a triangle wins a prize. assuming that a player's dart will always land on the poster, what is the probability of the dart landing in a triangle?

The answer is 0.19 (just took the test)

Step-by-step explanation:

Formula: 1/2bh

so it will be 1/2 * 8 * 8 (8 is from the base and height of the triangle)

= 32

Then you do 32 * 4 which equals 128 (this is the area of the triangles)

Next

Formula: bh

26*26 (the side lengths of the square poster)

= 676

Lastly:

128/676 (divide)

=0.189 --> which rounds to 0.19

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
