Step-by-step explanation:
you did not even try a calculator to find the result ?
64 is 8×8 or 8².
so, sqrt(64) = 8.
similarly for 4 :
4 is 2×2 or 2².
so, sqrt(4) = 2
so,
sqrt(64)/ sqrt(4) = 8 / 2 = 4
so, d. is the right answer.

Answer:
Answer:
6 days
210 pages
Step-by-step explanation:
As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.
Now since he reads 35 pages per day.
Then mathematically;
y = 35x
For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)
To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that
Also; y = 30(x + 1)
Equating the two situations
35x = 30(x + 1)
35x = 30x + 30
35x -30x = 30
5x = 30
x = 30/5
x = 6 days
This means that it will take Amir 6 days to catch Jese.
The number of books they would have read by then is y = 35x = 30(x + 1)
= 35 * 6 or 30(6+1)
= 210

Answer:
B.) 166
Step-by-step explanation:
10 x 2 = 20
12 x 10 = 120
13 x 2 = 26
20 + 120 + 26 = 166
