Answer:
On Saturday, when 12 weeks passed
Step-by-step explanation:
Tom gets his hair cut every 3 weeks.
David gets his hair cut every 4 weeks.
Find the least common multiple of numbers 3 and 4:
This means that Tom and David will get their hair cut on the same day at 12th week (if the first week when they started has number 0).
You can think in another way:
Tom gets his hair cut every 3 weeks. He got his hair cut after 3 weeks, after 6 weeks, after 9 weeks, after 12 weeks passed.
David gets his hair cut every 4 weeks. He got his hair cut after 4 weeks, after 8 weeks, after 12 weeks passed.
The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y
-3x+8
<h2>
Average rate of lowering per minute = 36.67 ft/min</h2>
Step-by-step explanation:
After 10 minutes, the bell is at a depth of 600 ft
After 10 minutes
Depth of bell = 600 ft
After 40 minutes the bell is at a depth of 1,700 ft.
After 40 minutes
Depth of bell = 1700 ft
Time gap = 40 - 10 = 30 minutes
Depth fallen = 1700 - 600 = 1100 ft
We have
Depth fallen = Average rate of lowering per minute x Time gap
1100 = Average rate of lowering per minute x 30
Average rate of lowering per minute = 36.67 ft/min
So the answer to this question is:
A= bees: f(t) = 1500 × (0.88)∧t
plants: g(t) = 800 - 25×t
B: (Bees) 1500 × (0.88)∧6= 696.60
After 6 months (696 bees ):
800 - 25×6 = 650 (Flowering Plants)
After 6 months:
650 flowering plants
C: 1500 × (0.88)∧t=800 - 25×t
t = 6.779965672
Answer is it will take 7 months or 6 for the bees and the plants.
Hope this helps!
Answer:
25
Step-by-step explanation:
Remember that multiplication and division will result in a positive number if no or two negative signs are present. So here, you ignore the negative signs.
All you really have to do is divide 50 by 2, which results in 25.
