24. +Enem [H2] É muito comum associarmos o conceito de deserto a lugares quentes, mas é bom lembrar que, mesmo
num deserto como o Saara, as temperaturas variam muito.
Durante o dia, a temperatura é muito alta e, durante a
noite, a temperatura cai drasticamente. Num dia típico
de deserto, a temperatura máxima, durante o dia, foi de
45 °C e a mínima, durante a noite, de 10 °C. Conside-
rando que a variação de temperatura, entre o ponto de
fusão da água e o seu ponto de ebulição, é de 100 °C na
escala Celsius e de 180 °F na escala Fahrenheit, a variação
de temperatura nesse dia típico de deserto foi, na escala
Fahrenheit, de aproximadamente:
a) 50 °F
c) 95 °F
e) 113 °F
b) 63 °F
d) 100 °F​

step-by-step explanation:

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
