Answer:
5/3min
Step-by-step explanation:
Yo only have to divide 5/6 miles by 3/6 mile/min to know the time it will take to cover a distance given a velocity.
5*6=30
6*3=18
30/18 = 5/3min!!
Answer:
55
Step-by-step explanation:
we have 342 students, subtract 12 because we need only kids riding the bus, now we have 330 kids, we divide the 330 kids between 6 buses 330/6, our answer is 55.
DB/dt = 1/5(100 - B)
5/(100 - B) dB = dt
-5 ln (100 - B) = t + C
Since B(0) = 20, then
-5 ln (100 - 20) = C
i.e. C = -5 ln 80
Thus -5 ln (100 - B) = t - 5 ln 80
or t = 5 ln 80 - 5 ln (100 - B) = 5 ln (80 / (100 - B))
When the weight = 40 grams
t = 5 In (80 / 100 - 40) = 5 In (80 / 60) = 5 ln (4/3) = 1.438 days
Rate of weight gain = 40 / 1.438 = 27.8 grams per day
When the weight = 70 grams
t = 5 ln (80 / 100 - 70) = 5 ln (80 / 30) = 5 ln (8/3) = 4.9 days
Rate of weight gain = 70/4.9 = 14.27 grams per day.
Therefore, the duck gains weight faster when it weighs 40 grams.

Answer:
b ≈ 8.60 ft
Step-by-step explanation:
The formula of a parallelogram is
A = bh
Divide each side by h
b = A/h
b = 62⅓/7¼
b = (187/3) ÷ (29/4)
b = 187/3 × 4/29
b = 748/87
b = 8⁵²/₈₇ ft
b ≈ 8.60 ft
The base of the window is about 8.60 ft long.
