You need the greatest common factor of the two numbers.
First, we find the prime factorization of each number.
72/2 = 36
36/2 = 18
18/2 = 9
9/3 = 3
3/3 = 1
72 = 2^3 * 3^2
90/2 = 45
45/3 = 15
15/3 = 5
5/5 = 1
90 = 2 * 3^2 * 5
To find the GCF, use only common factors with the lower exponent.
Both 72 and 90 have 2 as a factor. 72 has 2^3, and 90 has 2. 2 has a lower exponent than 2^3, so we use 2.
Both 72 and 90 have 3 as a factor. The both have 3^2, so we use 3^2.
90 has 5 as a factor, but 72 does not, so 5 is not a common factor, so we do not use 5.
The GCF is the product of the factor we use.
GCF = 2 * 3^2 = 2 * 9 = 18
Answer: The greatest number of students he can place in a row is 18.
I think the digit 2 would repeat indefinitely 2, 4, 8, 16, yada yada. Hope it helped
The labor-force participation rate of Belgium in 2017 was 77.78%
1.
Given:
Adult population = 4500
Number of employed in 2017 = <em>2800</em>
Number of Unemployed in 2017 = 700
Labor force participation rate = (employed + unemployed) / total population × 100
= (2800 + 700) / 4,500 × 100
= 3,500 / 4500 × 100
= 0.777777777777777 × 100
= 77.77777777777777%
Approximately, 77.78%
2.
Given:
Adult Population in 2016 = 3500
Number of employed in 2016 = 1800
Number of Unemployed in 2016= 600
Unemployment rate = unemployed population/ total labor force × 100
= 600 / 3,500 × 100
= 0.171428571428571 × 100
= 17.14285714285714%
Approximately,
17.14 %
Therefore, the unemployment rate of Japan in 2016 was 17.14%

Answer:
m = -3/5
Step-by-step explanation:
since both lines are given as "parallel", they will have the same slope, so we only need to solve for one.
we will put this equation into slope-intercept form to find the slope
3x + 5y - 16 = 0
3x + 5y = 16
5y = -3x + 16
y = -3/5x + 16/5
m = -3/5
