it would be 66.6% i think
Answer:
- a) NTRD standard price = $26.30
- b) range: $11.20 to $33.00, a range of $21.80
Step-by-step explanation:
a) The average is the sum divided by the number of contributors. Let n represent the standard price at Night-Time Rest Days. Then ...
... ($22.45 +18.55 +24.50 +11.20 +n)/5 = $20.60
... 76.70 + n = 103.00 . . . . multiply by 5 and collect terms
... n = $26.30 . . . . standard price at NTRD
b) The lowest standard price is $11.20. The highest breakfast price is $33.00. The range is the difference between these ...
... $33.00 -11.20 = $21.80 . . . . range in cost for a single night
Answer:
3 seconds.
Step-by-step explanation:
Since we are figuring out when the water balloon will hit the ground, y will need to be equal to 0.
0 = - 16t² - 16t + 96
Now we simply factor the trinomial to find t.
0 = -16(t² - t - 6)
0 = (t - 3)(t + 2)
t - 3 = 0 ⇒ t = 3
t + 2 = 0 ⇒ t = -2
Since we are referring to time, we need to use the positive value. Therefore, the water balloon will take 3 seconds to hit the ground.
Answer:
D
Step-by-step explanation:
Given that the ratio of side lengths = 8 : 3, then
ratio of volumes = 8³ : 3³ = 512 : 27 → D
