Answer:
1/6
Step-by-step explanation:
De la pregunta, sabemos:
30/90 del número de plantas de un cultivo de caña está contaminado.
30/90, simplificamos aún más
30/90 => 3/9 => 1/3
De estos, la mitad han sido tratados.
La fracción de los cultivos tratados son:
1/2 de 3/9 = 1/2 × 1/3
= 1/6
La fracción del número de plantas del cultivo que no ha sido tratada se calcula como:
1/3 - 1/6
El mínimo común denominador es 6
= (2 × 1) - (1 × 1) / 6
= 2 - 1/6
= 1/6
1. Divide the first row by -4
(1, -5/4, -3/2)
2. Multiply the first row by -2
(-2, 5/2, 3)
3. Subtract the first row from the third row and restore it.
1 (1, -5/4, -3/2)
3 (0, -15/2, 1)
4. Restore the first row to the original view
(-4, 5, 6)
5. Divide the second row by 4
(0, 1, 1)
6. Multiply the second row by -15/2
(0, -15/2, -15/2)
7. Subtract the second row from the third row and restore it
2 (0, 1, 1)
3 (0, 0, 17/2)
8. Restore the second row to the original view
(0, 4, 4)
9. Multiply the main diagonal elements
-4 x 4 x 17/2 = 136
Answer: Δ = 136
Answer:
B.
Step-by-step explanation:
Using the formula
S = r∅
Where s is Arc length,l
R is radius
∅ is radian measure for angle RAD
Substituting
L = R∅
So
∅ = L/R
X= 18 is what I caculated
Breads/cereals;
11 * 140 = 1540 calories
Fruits/vegetables;
9 * 60 = 540 calories
Meat/milk;
x * 180 = 2800 - (1540 + 540)
180x = 2800 - 2080
180x = 720
x = 4 servings
