She paid 10 in advance so that's 30-10 which is 20.
As it's 4 dollars per hour, 20 will be divided by 4.
20/4 = 5
So 5 hours.
Answer:
8.2
Step-by-step explanation:
-7.2 to -7.2 is 0
-9.3 to -1.1 is 8.2
Pythagorean theorem is a^2+b^2=c^2
0^2=0
8.2^2=67.24
0+67.24=0
√67.24=8.2
The distance between the to points is 8.2
The expression for (t) \Join (t+2) - (t+1) \Join (t+1) is ( + t - 2 ) ( + t - 6 ).
The given operation is \Join such that x Join y = (x+2)(y-3).
We are to apply the \Join operation in the given expression.
t \join (t+2) - (t+1) \Join (t+1) and find its final expression.
Using this operation: x Join y = (x+2)(y-3).
Let's find,
t \join (t+2)
Here,
x = t and y = t + 2
= ( t+2 ) ( t+2 - 3 )
= ( t + 2 ) ( t - 1 )
(t+1) \Join (t+1)
Here,
x = t + 1 and y = t + 1
= ( t + 1 + 2 ) ( t + 1 - 3 )
= ( t + 3 ) ( t - 2 )
t \join (t+2) - (t+1) \Join (t+1)
= ( t + 2 ) ( t - 1 ) - ( t + 3 ) ( t - 2 )
= ( - t + 2t - 2 ) ( - 2t + 3t - 6 )
= ( + t - 2 ) ( + t - 6 )
Thus the expression for (t) \Join (t+2) - (t+1) \Join (t+1) is:
( + t - 2 ) ( + t - 6 )

This is a multiplication problem.
2 1/2 * 2/3 = 5/2 * 2/3 = 10/6
She will use 10/6 or 1 2/3 cups of vegetable oil (or applesauce idk).
Hope this helps, let me know if it's wrong!
