2^2 , or 4
since the exponents have the same base, we can subtract the exponent of the numerator by the exponent in the denominator.
So 2^-3 - 2^-5 = 2^(-3-(-5)) = 2^2
The new exponent is 2 because -3-(-5) is equal to 2.
I believe those are decimals
Answer:
B
Step-by-step explanation:
To answer this question, we have to familiar with the characteristics of qualitative data. Qualitative data is a type of data that is OBSERVED not measured. It corresponds to qualities of something. Qualitative data cannot be expressed in numerical form. It is usually collected through observation methods or interviews.
So from the above options,
Option A
The price of the last set of tires is a measurable quantity which can be expressed in numerical form. So it would not be the answer.
Option B:
The appearance of tires is a quality which can only be seen or observed but cannot be expressed in numerical form so it is the right answer for the question.
Option C & D:
The number of miles is a numerical quantity as it is measured so it will not be the correct answer to the question.

Answer:
230.77 seconds or about 3.85 minutes (2 minutes 50.4 seconds)
Step-by-step explanation:
First I will convert the minutes into seconds to make this a little easier.
1:01.71 would just be 61.71 seconds
400/61.71 is her speed for the first race. (speed is distance/time)
That is approximately 6.5 meters per second
time is distance/speed
1500/6.5= 230.769...
I do not know what you need to round to, but Juliette would take 230.769 seconds to run the 1500 meter race.
