Look at the picture.
Corresponding Angles are equal.
Alternate Angles are equal.
Consecutive Angles add up to 180°.
----------------------------------------------------------------------
3a and 45 are Consecutive Angles. Therefore
3a + 45 = 180 |subtract 45 from both sides
3a = 135 |divide both sides by 3
<h3>a = 45.</h3>
----------------------------------------------------------------------
(2c - 1) and 45 are Corresponding Angles. Therefore
2c - 1 = 45 |add 1 to both sides
2c = 46 |divide both sides by 2
<h3>c = 23.</h3>
----------------------------------------------------------------------
3a and (12b + 3) are Alternate Angles. Therefore
3(45) = 12b + 3
135 = 12b + 3 |subtract 3 from both sides
132 = 12b |divide both sides by 12
<h3>b = 11.</h3>
Responder:
1 hora 55 minutos; 22 horas 45 minutos
Explicación paso a paso:
Dado que:
Tiempo el primer día = 15 minutos
Minutos adicionales cada día siguiente = 5 minutos
Número total de días
Usando la fórmula del enésimo término de una progresión aritmética:
Tn = A + (n - 1) d
A = primer trimestre = 15
d = diferencia común = 5
n = enésimo término
Tiempo de nado el último día (n = 21)
T21 = 15 + (21 - 1) 5
T21 = 15 + 20 * 5
T21 = 15 + 100
T21 = 115 minutos
= 1 hora 55 minutos
SEGUNDO.)
Suma de minutos durante las 3 semanas
Suma de n términos:
Sn = n / 2 * (primer término + último término)
Primer término = 15
Último trimestre = a21 = 115 minutos
n = número de términos = 21
Por lo tanto,
Sn = 21/2 * (15 + 115)
Sn = 10,5 * (130)
Sn = 1365 minutos
= 22 horas 45 minutos
The type of cost that is associated with the state the car was purchased is C. tax, title, and registration.
<h3>Why are these associated with the state of purchase?</h3>
Different states in the United States have different requirements for registering a car after purchase.
There are also different tax rates charged per state, and the title requirements of the car are different by state as well.
In conclusion, option C is correct.
