The population is increasing at the rate of 220
Explanation:
Given that the population of Hannah's town is increased from 1500 to 2600 in five years.
This can be written in expression as
and
We need to determine the rate of change of population.
The rate of change can be determined using the formula,
where and
Substituting the values in the formula, we have,
Simplifying, we have,
Dividing, we get,
220
Thus, the population is increasing at the rate of 220
The division algorithm is (y+6)(y-2) +(-2).
<h3>What is Division Algorithm ?</h3>
When A and B are two expressions or numbers and Q and R are quotient and remainder respectively where r is always less than the divisor
The answer can be written in the form of
Q*D +R
The given expression is
on dividing
Quotient Q = y+6
Remainder = -2
So it can be written as
(y+6)(y-2) +(-2)

Answer:
20 times
Step-by-step explanation:
This is calculated as:
The number of coal China consumes ÷ The number of coal Japan consumes
The number of coal China consumes =4 × 10⁹
The number of coal Japan consumes
= 2 × 10⁸
4 × 10⁹/2 × 10⁸
= 20 times
