16. ✧❀⌨︎QUIZ⌨︎❀✧ 1. Nagito and Hajime each ordered a taco at a restaurant. The price of Nagito's taco was x dollars and the price of Hajime's taco was $1 more than the price of Nagito's taco. If Nagito and Hajime split the cost of the tacos evenly and each paid a 20% tip, which of the following expressions represents the amount, in dollars, each of them paid? (Assume there is no sales taxes) A.) 0.2x + 0.2 B.) 0.5x + 0.1 C.) 1.2x + 0.6 D.) 2.4x + 1.2 2. [tex]\bold{\boxed{h(t)=-16t^{2}+110t+72 }}[/tex] The function above models the height h, in feet, of an object above ground t seconds after being launched straight up in the air. What does the number 72 represent in the function? A.) The initial height, in feet, of the object B.) The maximum height, in feet, of the object C.) The initial speed, in feet per second, of the object D.) The maximum speed, in feet per second, of the object

Naruto = N
Isayama = H
N = x
H = N + 1
H = x + 1
total bayaran = 120%x + 120%(x + 1) [tex] \text{karena membayar tip dua puluh persen maka harga nya menarik dua puluh persen} [/tex]
= 1,2x + 1,2(x + 1) = 1,2x + 1,2x + 1,2
= 2,4x + 1,2
Tapi karena mereka membagi taconya menjadi dua, maka satu orang bayar ½ kalo harga total
= ½(2,4x + 1,2)
= 1,2x + 0,6[Opsi C]2.h(t) = -16t² + 110t + 72
Nah, bagaimana cara mendapatkan 72? yaitu dengan memasukan t = 0 atau detik detik objek diluncurkan, seperti ini
h(0) = -16(0)² + 110(0) + 72
Nah, apa yang terjadi saat t = 0? Yap itu adalah ketinggian awal yaitu h(0) = 72 kaki
maka jawabannya :
A.) The initial height, in feet, of the objectA.) Ketinggian awal, ukuran kaki, dari objek17. Calculate the distance between sun and earth if light takes 8 minutes to reach earth speed of light is 3x10^8m/s
s=v/t
8 minutes = 480 s
s=300000000/480
s=625.000 m
18. In a triathlon, Ari cycles 50 km in 1.75 hours, swims a distance of 1.2 km at an average speed of 2.5 km/h, and runs at an average speed of 9km/h for 10/9 hours. Find his average speed for the entire competition.
Answer:
18.31 km/hrExplanation with steps:
Average speed = Total distance / total timeCycling distance = 50 km, cycling time = 1.75 hr
Swimming distance = 1.2 km, swimming time = 1.2/2.5 = 0.48 hr
Running distance = 9 x (10/9) = 10 km, running time = 10/9 hr
Therefore
Average speed = Total distance / total timeAverage speed = (50 + 1.2 + 10) / (1.75 + 0.48 + (10/9))
Average speed = 61.2 / (3007/900)
Average speed = (61.2 x 900) / 3,007
Average speed = (61.2 x 900) / 3,007
Average speed = 55,080 / 3,007
Average speed = 18 954/3,007
Average speed = 18.31 km/hr
