Answer:
Step-by-step explanation:
after one year= 4/100 times 2000
= 80 people
after 15 years= 80 times 15=1200 people
2000+1200=3200 people
Answer:
18
Step-by-step explanation:
1) 90 --- 100%
x --- 20%
x = 90*20/100 = 18
2)
20 % = 20/100 = 0.2
20 percent (0.2) of (*) 90 = 0.2*90 = 18
Answer:
84 feet
Step-by-step explanation:
Let the feet be A
1 foot = 0.33 yard
A feet = 28 yards
Cross multiply
A x 0.33 = 28 x 1
Divide both sides by 0.33
A x 0.33/0.33 = 28/0.33
A = 84.84
A = 84 feet
Therefore, there are 84 feet in 28 yards
True.
For example,
2sqrt(2)=sqrt(8) ..... irrational
3pi ................irrational
Since a rational can always be represented by a fraction, while an irrational cannot, therefore the product of the two will not be represented by a fraction, therefore irrational.
