Answer:
- 3 \frac{4}{5} + 1 \frac{2}{5}
= -frac{19}{5} +frac{7}{5}
= frac{-19+7}{5}
= frac{-12}{5}
= -2frac{2}{5}
5 \frac{3}{5} - 7
= -2+\frac{3}{5}
= frac{-10+3}{5}
= frac{-7}{5}
= -1\frac{2}{5}
Step-by-step explanation:
Answer:
Black = 84 cm^2
Blue = 84cm^2
gold = 60.2cm^2
1 ornament = 228.2 cm^2
100 ornaments - 22820 cm^2
Step-by-step explanation:
Black is a rectangle = A = l*w = 7*12 = 84 cm^2
We have 2 blue This is a triangle so multiply by 2 the area of a triangle
2 * A = 2(1/2 b*h) = bh = 12*7 = 84 cm^2
We have 2 gold This is a triangle so multiply by 2 the area of a triangle
2 * A = 2(1/2 b*h) = bh = 8.6*7 = 60.2 cm^2
The total surface area for one ornament is
84+84+60.2 = 228.2
100 ornaments
Multiply by 100
100 *228.2 = 22820 cm^2
112 me dió a eso mira haber si es si no trate.
