(184-94)/5=18
This means that she fills up 18 liters every minute. Thus she will be done in->
184(original amount)+(2 minutes (time passed during first data point)*18(rate of water)=184+36=220
To find the total time taken we divide 220 by 18 which is 220/18=12 2/9
7x = 40
7x + 4y = 40
The first equation represents that in total, the 7 tickets whether they are for adults or children costs $40.
The second equation represents that x = adult and y = children tickets both add up to equal $40.
Answer:
There are 548.64 cm in 18 feet.
Step-by-step explanation:
We know that, 1 inch = 2.54 centimeters.
We need to convert 18 feet to centimeters
Also, 1 foot = 12 inch
Firstly we will convert 18 feet to inch.
18 feet = 12 × 18 inch
= 216 inch
Now to convert 18 feet to centimeters, multiply 216 inch by 2.54 cm as follows :
216 inch = 2.54×216 centimeters
= 548.64 cm
Hence, there are 548.64 cm in 18 feet.
Answer:
Step-by-step explanation:
Taking into account that the growth rate of the number of species on the island is proportional to the density of species (number of species between area of the island), a model based on a differential equation is proposed:
This differential equation can be solved by the method of separable variables like this:
with what you get:
. Taking exponentials on both sides of the equation:
how do you have to 
, then
