150 because 6 is half of 12. So then the half of 100 is 50. The answer is 150
Respuesta:
Volumen = 0.0010126 m³
Ancho = 7,84 N
Explicación paso a paso:
Dado que:
Masa, m de alcohol = 0,8 kg
Densidad del alcohol, d = 790 kg / m³
Recordar :
Densidad, d = masa, m / volumen, v
Volumen = masa / densidad
Volumen = 0,8 kg / 790 kg / m³
Volumen = 0.0010126 m³
Peso, W = densidad * aceleración debido a la gravedad * volumen
Ancho = 790 * 9,8 * 0,0010126
W = 7.8395
Ancho = 7,84 N

Answer:
1: 24 girls
2: 640
3: 300
4: 3/10
5: 42
Step-by-step explanation:
1: 2/5 × 40
80÷ 5
16
girls = 40- 16
= 24
2: 1/3 × 960
960 ÷3
= 320
Left = 960 - 320
= 640
3: 3/8 × 480
1440 ÷ 8
= 180.
Left = 480 - 180
= 300
4: 2/5 × 3/4
= 6/20
= 3/10
5: 2/5 × x = 18
2x = 28 × 5
2x = 140
x = 70
70 - 28
= 42
Answer:
x = ± 2
Step-by-step explanation:
Given
f(x) = x² + 1 and (x, 5 ) is a solution then f(x) = 5
Equating the two gives
x² + 1 = 5 ( subtract 1 from both sides )
x² = 4 ( take the square root of both sides )
x = ± = ± 2
Thus (- 2, 5) and (2, 5) are solutions
