Sladkaya [172]3 years ago

She has 2 $20 and 1 $10 bills.
Since it says that she has 1 more 20 dollar bill, we should subtract 50 by 20.
That gives us 30.
Then we should subtract it AGAIN, 30 by 20.
That gives us ten.
Finally, well subtract that, 10 by 10.
Equation:
[50-(20x2)]-10

A square poster has a side length of 26 in. Drawn on the poster are four identical triangles. Each triangle has a base of 8 in.
Firdavs [7]
To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.

Divide the area of the combined areas and the total area to find the probability of landing on a triangle.

A = 1/2bh
      1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)

A = bh
     26 x 26
A = 676 square inches

128/676 = 0.189

There is an approximate probability of 0.19 of hitting a triangle.
