Answer:
The possible values for 1/y of the expression 0.125 < y < 0.25 are in the range
4 < 1/y < 8
Step-by-step explanation:
The given information are;
The range of values of y are 0.125 < y < 0.25, therefore, we have;
The boundaries of the function, y are 0.125 and 0.25
The inverse of the boundaries of the function, y are 1/0.125 = 8 and 1/0.24 = 4
Therefore;
The limits of the inverse of the function y are ;
The inequality that represents 1/y is therefore;
1/0.25 < 1/y < 1/0.125 or 4 < 1/y < 8
The possible values of 1/y for the expression 0.125 < y < 0.25 are therefore;
4 < 1/y < 8.
I hope its clear that answer to the first part
Answer:
x/2-9=24
Explanation:
Nine less:
-9
Half a number:
x/2
So nine less than half a number:
x/2-9
Is 24:
=24
So x/2-9=24
To solve for the number:
Add 9 to both sides:
x/2-9+9=24+9
x/2=33
Multiply both sides by 2:
2(x/2)=33(2)
x=66
Answer:
240 min or 4 hours
Steps:
1- 200 pages/ 25 pages > 8
2- 8 x 30 minutes > 240 minutes
3- Optional- To convert to hours- 240 minutes/ 60 minutes > 4 hours
Hope this helps! If it does would u consider a brainliest.
