Answer:

Friday night.

Less expensive.

Step-by-step explanation:

Cost of 1 ticket on Friday = 48/3 = $16.

Cost on Saturday = 36 / 2 = $18.

Now 96 / 6 = $16 so the brother and his friends will have to go to the Friday concert. From the above costs we see that they did buy the less expensive ticket.

Need help with both 18 and 19.

Tema [17]

18. Answer: D

Step-by-step explanation:

First, find the measure of the missing angle.

65° + 57° + x = 180°

122° + x = 180°

x = 58°

Next, match up the angles with the opposite sides:

65° ⇄ Swim

58° ⇄ Bike

57° ⇄ Run

Lastly, put them in order from least to greatest:

57° < 58° < 65°

⇒ Run < Bike < Swim

The only multiple choice option that is correct is Bike > Run.

19. Answer: 22.3°

Step-by-step explanation:

$sin\theta = \dfrac{opposite}{hypotenuse}$

$sinD= \dfrac{EF}{DE}$

$sinD= \dfrac{19}{50}$

$D= sin^{-1}\bigg(\dfrac{19}{50}\bigg)$

D = 22.3°
