Answer:
i think it would be $80 (brainliest??)
Step-by-step explanation:
jane had a total of $200 BEFORE she spent on 2 games
1. $40
2. $40
3. $40
4. $40
5.$40
2 games = $80
3 games = $120 (money she had left)
Inverse functions are always the opposite of course therefore, f^-1(x)=x+12
I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
PLEASE SEE ATTACHED IMAGE. For this case what you should do is find the arc length.
By definition, the arc length is given by:
s = R * theta
Where,
R: radio
theta: angle
Substituting values:
s = (21) * (85 * (pi / 180))
s = 31.15412715
nearest whole number:
s = 31 inches
Answer:
C
31 inches
Let the cost of one sheep and one cow be x and y respectively.
Therefore,
5x+5y=129
10x+17y =177
Solving the two equations,
Multiply the first equation by 2 and subtract the second from the results;
10x+10y = 258
10x+17y = 177
0x-7y = 81 => y= $-11.57 (cannot be a negative value). The details of the question need to be checked.
Now,
5x+5y = 129 => 5x-57.86 =129=>5x = 186.86 => x= $37.37
There would be 5184 ways in which each subject books can be selected.
<u>Explanation:</u>
Number of geography books = 5
Number of chemistry books = 4
Number of Science books = 7
Different ways of selecting geography books = 5!
= 5 X 4 X 3 X 2 X 1
= 120
Different ways of selecting chemistry books = 4!
= 4 X 3 X 2 X 1
= 24
Different ways of selecting Science books = 7!
= 7 X 6 X 5 X 4 X 3 X 2 X 1
= 5040
Total different possible ways they can select them = 120 + 24 + 5040
= 5184
