Rational numbers are numbers which can be written as a fraction (the formula is p/q). They don't include roots we can't solve in order to get a whole number and pi.
A. 776, pi, 25.209, √9 ---> NO (because of pi)
B. 726, 7/34, 20.209, √9 ---> YES
C. √3, 7/39, 20.3, √9 ---> NO (because of √3)
D. 726, 7/34, 20.209, √5 ---> NO (because of √5
Note that √9 = 3, so it IS a rational number.
Answer:
2355 cm^2
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h
V = 1/3 (3.14) (15)^2 (10)
V =2355
There is 20% decrease in the number of members.
Step-by-step explanation:
Given,
Members last year = Old value = 30
Members this year = New year = 24
Change = New value - Old value
Change = 24 - 30
Change = -6
The negative sign indicates the decrease.
Decrease percent = 
Decrease percent = 
Decrease percent = 
Decrease percent = 20%
There is 20% decrease in the number of members.

Hey there,
It take 45 min to complete 75% of the wall
1% = 45 / 75
= 0.6
100 % = 0.6 x 100
= 60 min
It takes her 60 mins or 1 hour to finish building the wall.
Hope this helps :))
