The triangle <span>pyramid</span> is made up of 4 triangles.
------------------------------------
Formula:
------------------------------------
Area of triangle = 1/2 x base x height
------------------------------------
Area of the bottom triangle:
------------------------------------
Area = 1/2 x 9 x 7.8
Area = 35.1 yd²
------------------------------------
Area of the 3 side triangles:
------------------------------------
Area = 3 [ 1/2 x 9 x 10 ]
Area = 135 yd²
------------------------------------
Total Area:
------------------------------------
Total Area = 135 + 35.1
Total Area = 170.1 yd²
------------------------------------------------------------------------
Answer: Surface Area = 170.1 yd².
------------------------------------------------------------------------
Answer: 1)The drivers with low alcohol in take from the breathlyser, being above the limit, A = 5/100;
2)The drivers above the alcohol limit, give reading below that level, B = 15/100;
3) The drivers above the alcohol limit that are arrested at radom by police, C = 12/100
Step-by-step explanation: a) A + B + C = 5/100 + 15/100 + 12/100 = 32/100
b) 1 - ( A + B + C) = 1 - 32/100 = 68/100
c) A = 5/100
d) 1 - 5/100 = 95/100
P=2*(5ft +7 ft)
P=2*12 ft
P=24 ft - is the answer
