This is how u write 13 and 9/10 in standard form 13 9/10.
Answer:
Step-by-step explanation:
D = {x | x is a whole number}
D = {0, 1, 2, 3, 4,......}
E = {x | x is a perfect square between 49 and 100}
E = {64, 81}
F = {x | x is an even number between 10 and 20}
F = {12, 14, 16, 18}
D∪F = {x | x is whole number}
D∩F = {x | x is an even number between 10 and 20}
D∩E = {x | x is a perfect square between 49 and 100}
E∩F = {null set}
D∩(E∪F) = {12, 14, 16, 18, 64, 81}

Answer:
Ethan can type 12 pages before the meeting starts.
Step-by-step explanation:
Given:
Number of pages he can type =2
Number of hours he can type 2 pages = 
We need to find number of pages he can type in 
Solution:
Now first we will find number of pages in 1 hour
So we can say;
In
= 2 pages
In 1 hour = number of pages he can type in 1 hour
By Using Unitary method we get;
number of pages he can type in 1 hour = 
Now we can say that;
In 1 hour = 16 pages
So
= number of pages he can type in 
Again By using Unitary method we get;
number of pages he can type in
= 
Hence Ethan can type 12 pages before the meeting starts.
