78 * 3/4 hour,
it is 6 hours
First one is 4^2 or just 16.
Second one is using√ So what you want to do is 2√16
Hope this helps
Set up a ratio to find the number of pages read in 80 minutes:
40 pages/ 50 minutes = x pages/ 80 minutes
Cross multiply:
50x = 3200
Divide both sides by 50:
X = 3200/50
X = 64
He will read 64 pages in 80 minutes.
200 -64 = 136
There will be 136 pages left.
Answer:
961 TT cm^2
Step-by-step explanation:
- c=TTD note that d is diameter which is 62 thus radius is half 31

- Answer is 961 TT cm^2
Given:
To find:
The missing value.
Solution:
Let the missing value be m.
Using exponent rule: 
Using exponent rule: 
Equate x terms and y terms.
and 
If the bases are same, then the powers are equal.
Subtract 5 from both sides.
The missing value is -3.
