Given the scenario, no valid integer input would result in an output of $3 from Dorothy's ? button on her calculator. The three conditions specified do not match any integer when the output is $3.
Given that the output of the ? button on Dorothy's calculator is $3, one thing that could have been input and fit one of the conditions is 4, because when an integer is divisible by 4, the calculator outputs its one-fourth. Since 4 is divisible by 4 and one-fourth of 4 equals 1, that's not correct. Now let's check the condition for even numbers not divisible by 4. The calculator outputs 1 more than half the number. So, if we plug in $3 as the output and solve the equation, we get: 3 = 1 + 1/2 (input). Solving for the input, we get 2*2 = 4, which is still wrong. So, finally, we check the condition for odd numbers. Here, the calculator outputs 1 less than triple the input. Substituting $3 as the output, we solve for the input: 3 = 3*(input) - 1. Solving for input, we get input = 4/3, which is not an integer. Therefore, there could not have been an integer input that resulted in a $3 output in this case.

Answer:
i think that the answer is 23/20
Step-by-step explanation:
20 liters is equal to 20,000 milliliters.
To convert liters to milliliters,
you need to multiply the value in liters by 1000 because there are 1000 milliliters in 1 liter.
Therefore, 20 liters is equal to:
= 20 liters x 1000 milliliters/liter
= 20,000 milliliters
So, 20 liters is equal to 20,000 milliliters.

Answer:
987
Step-by-step explanation:
(s.t)(x) = s(x) × t(x) = 3x(2 - x²) = 6x - 3x³
To evaluate (s.t)(- 7) substitute x = - 7 into the product
(s.t)(- 7) = 6(- 7) - 3(- 7)³ = - 42 + 1029 = 987
