A bee flies at 10 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 12 minutes, and then flies directly back to the hive at 8
feet per second. It is away from the hive for a total of 15 minutes.
a. What equation can you use to find the distance of the flowerbed from the hive?
b. How far is the flowerbed from the hive?
a. Write the equation. Let d be the distance of the flowerbed from the hive.
(Type an equation. Use integers or fractions for any numbers in the equation. Do not simplify.)
Answer:
a. 15 = d/600 + 12 + d/480
b. 800 feet
Step-by-step explanation:
a. Let distance between hive and flowerbed be "d" feet
Speed of bee during motion from hire to flowerbed = 10ft / sec = (10*60)fit/minute
Speed of bee during reverse motion = 8 ft/sec = (8*60)ft/min
Time which the bee stayed at flower bed = 12 minute
Time of its total journey = 15 minutes
Total Time = Time of travel from hive to flowerbed + Time of staying in flowerbed + Time of reverse travel
15 = d/10*60 + 12 + d/8*60
15 = d/600 + 12 + d/480....................(Required equation)
b. 15 = d/600 + 12 + d/480
d/600 + d/480 = 15 - 12
d/600 + d/480 = 3
4d + 5d = 3
2400
9d = 2400 * 3
9d = 7200
d = 7200/9
d = 800 feet
Hence, the flowerbed is 800 feet far from the hive.

Step-by-step explanation:
the answer is 177.75 lb; 178.25 lb
Answer:
I believe the question is asking what it was before it was rounded to 178.
Your answer is 177.5lb

a few things for it to come down to 1 question ------------------------------------------ 1:A boy cycles 20km in 140 minutes. How long would it take him to cycle 8km, at the same speed? ==== here it is 140mins over 20km, so 140/20 minutes on top --------- 2: It takes a garage owner 45 minutes to travel between his two garages 60 miles apart. Travelling at the same speed, how long would it take him to travel to his home 25 miles away? ======= here its minutes over miles, so 45/60 -------------- 3: A jet travels 320 km in 20 minutes. How far will it fly in 30 minutes? ===== here it's 320km over 20mins, so 320/20 b ------- The question: why is it that minutes are on top of miles despite it being a smaller number, when km is just whatever is larger?
Step-by-step explanation:
For number 1, the rate is 20km/140min
So you divide so the rate becomes 1km/(?)
20/20=1
140/20=7
1km/7min
Then to get it to 8km/(?) multiply both sides by 8
1x8=8
7x8=54
8km/54min
Answer: It would take him 54 min to cycle 8km
The function y = 14 +2.31x + 4.50 can be used to determine the cost in dollars for an Uber ride of x miles which takes no longer than 10 minutes. What is
the rate of change of the cost in dollars with respect to the number of miles?
Answer:
2.32dollar/mileStep-by-step explanation:
step one:
Given the function
y = 14 +2.31x + 4.50
we can solve for the rate of change by applying differentiation.
step two:
differentiating y which is cost with respect to x which is the miles
dy/dx= 0+2.32+0
dy/dx=2.32
Hence the rate of change of cost in the dollar to a mile is
2.32dollar/mile
