The first one A 7/2
You can just round up 6.75 -> 7 and 1.67->2
Answer:
4
Step-by-step explanation:
First off, integers are Whole Numbers (1,2,3,4, etc), so we are rounding the answer to the nearest whole number.
The square root of lets just say 25 means you are finding a number that multiplied by itself will equal 25 (the answer is 5).
Now for 13, there is no perfect square, however the closest whole number that multiplied by itself to 13 is 4.
4*4= 16
3*3=9
5*5=25
As you can see above 4 is the closest number to 13.
Now, the ACTUAL value of the square root of 13 is 3.60555128, but we are rounding up to the nearest whole number which is 4 :)
Answer:
Step-by-step explanation:
X={0,12,23}
Y={3,12,15}
X \ Y = { 0 , 23}
X/Y means the element should be only in X. We have remove the element in X if it is in Y
In this 0 and 23 is only in X
12 is X and Y. So it wont come in X/Y
Answer:
It will take him <u>20 days</u> to read a 300-page book.
Step-by-step explanation:
Given:
Stephen read a 90-page book in 6 days.
If he continues reading at that rate.
Now, to find the time it will take him to read a 300-page book.
So, we solve using unitary method:
If, Stephen read 90 pages in 6 days.
So, Stephen read 1 page in = 
days.
Thus, Stephen read 300 page in = 
Therefore, it will take him 20 days to read a 300-page book.
