Answer:
the previous population was 62,000.
Step-by-step explanation:
The current population of a city = 83,700
The population of a city has increased by 35% since it was last measured.
We have to calculate the previous population before increasing 35%.
Let the previous population be p
p +(35% × p) = 83,700
p + 0.35p = 83,700
1.35p = 83,700
p =
p = 62,000
Therefore, the previous population was 62,000.
Answer:
$7.50
Step-by-step explanation:
$42 × 3 = $126
$27 × 5 = $135
$126 + $135 = $261
$275 - $261 = $14
$14 - $6.50 = $7.50
Answer:
10.8 minutes
Step-by-step explanation:
Given data
We are told that the number of Jugs is 18
Filling the first 3 jugs has taken 5 minutes
let us find the filling rate
Rate= 3/5
Rate= 0.6 Jugs per minute
Hence the rate of filling is 0.6 Jugs per minute
Therefore the time take to fill the remaining 16 jugs is
TIme= Rate*Number of Jugs
TIme= 0.6*18
Time= 10.8 minutes
The practical rule would be, times that number, by the result of the first time you multiplied the first number. But, it would all depend by how much your're raising the number by.
<u>
For example:</u>
We do,
But, once again, this was an example. This would show and illustrate the rule of "raising a power".<span />
