Answer:
copy the first fraction, turn the division sign to a multiplication sign and flip the second fraction
Step-by-step explanation:
ex: 2/5 divided by 1/4
turn it to- 2/5 x 4/1

Answer:
D. 108 liters
Step-by-step explanation:
Given that the leak is ;
5 drops = 5 minutes
?= 4 weeks
Find number of hours in 4 weeks
1 week=7days
4 weeks=?--------------cross multiply
4×7=28 days
1 day=24 hours
28 days=?--------------cross multiply
28×24=672 hours
Hour= 60 minutes
672 hours=?
672×60=40320 minutes
Finding the leakage in 4 weeks
80 drops= 5 minutes
?=40320 minutes------------cross multiplication
(40320×80)÷5 =645120 drops
Finding the liters of water wasted in 4 weeks
60 drops of water= 10 milliliters
645120 drops of water=?-------------cross multiply
(645120×10)÷60 =107520 milliliters
But you know
1 milliliter=0.001 liters
107520 milliliters=?-----------cross multiply
107520×0.001
=107.52 liters
=108 liters
Answer:
630+0 is 630. So 630 is equal to 630.
Answer:
This is an exponential growth equation of the form:
f(t) = A*(r)^t
Where:
A is the initial quantity of something, suppose that is the population of some kind of animal
r is the rate of growth
t is the variable, usually represents a unit of time.
f(t) is the population of the animal at the time t.
For this question, we have the equation:
b(t) = 1200*(1.8)^t
And this represents the population of a kind of bacteria as a function of time.
a) 1200 is the initial population of the bacteria.
b) the 1.8 is the rate of growth.
c) Now we have the equation:
b(t) = 1000*(1.8)^t
In this case, 1000 will represent the initial population of bacteria for this second study.
And the difference between the 1200 for the first study, and the 1000 for this second study, means that for the first study the initial population of bacteria was larger. (200 units larger).
