Answer:
55 yds squared
Step-by-step explanation:
Square = 20
Both rectangles = 35
Note/Disclaimer: My explanation may not help you understand, but I used the explanation area to place my notes down... I use mental math.
1 )
z =180 - 112 = 68
y = 360 - 68 - 87 - 103 = 102
2 ) tan Q = 171 / 50 = h / 160 h = 171 (160) /50
=27310/50 = 547.2 cm
3) 5 pint = 2.36588 L
4)
1 kg = 35.274 Oz
so, 133 oz =3.77049 = 3.77 kg
5) area = ( 1/2 * 20 * 15) + ( 36*20 ) + ( 1/2 * pie * r^2) = 150 + 720 + ( 1/2 * 3.14 * 100) = 150+720+157 = 1027 sq. cm
hope i helepd a bit :-)

Answer:
The percent of error in the measurement is 2%
Step-by-step explanation:
The percent of error associated with a reported measurement is calculate using the formula;

The error associated with a measurement is defined as half of the smallest unit of measurement used. The measurement reported was 2.5. The smallest unit of measurement for this reading is 0.1. The error is thus;
error = 0.1/2 = 0.05
The percent of error is thus;

Answer:
math error ...............
