Select the correct answer. Peter is conducting a chemical experiment in a controlled environment. The initial temperature of the chemical solution was 20°C. The temperature of the solution was 1.5 times the initial temperature after 3 minutes. The temperature of the solution continued to increase at this rate. This situation is graphed below.

Let x represent the number of minutes passed after the start of the experiment, and let f(x) represent the temperature of the solution.

Once the temperature reached 45°C, the experiment was stopped. Over which interval did Peter conduct the experiment?

A.
2 ≤ x ≤ 6
B.
0 ≤ x ≤ 2
C.
0 ≤ x ≤ 3
D.
0 ≤ x ≤ 6

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
