So she practices 29 minutes per day
Answer:
I believe it is rational
Step-by-step explanation:
irrational is a number that continues and never has an end i believe.
The formula that we want to use here is S = D/T.
S = Speed
D = Distance
T = Time
So, we know that S = 550 and T = 3.5, so we can plug them in.
We get 550 = D/3.5
Multiply by 3.5 on each side, and you figure out that the plane has traveled 1925 miles.
Answer:
4000 is size of a crowd walking in a charity fundraising March.
Step-by-step explanation:
Given:
Dimensions of rectangular space 10 feet by 12000 feet
So we can say that,
Length = 1200 ft
Width = 10 ft
Now we will calculate the area of rectangular space which is given by
Hence Area will be = 
Now we know that 40 people occupy a rectangle measuring 10 feet by 12 feet.
Length = 12 ft
Width = 10 ft
Area = 
It says that 40 people are occupied in 120 
So how many people will be there in 12000 
By using unitary method we get,
Number of people = 
Size of a crowd walking in a charity fundraising March is 4000.
S=i(n-1)+2*(n-1)+1 perhaps
