The equation for circumference is: 2 x Pi x r

You used the diameter (9), rather than the radius. The radius is the diameter divided by 2. Therefore, your equation should be: 2 x 3.142 x 4.5, NOT 2 x 3.142 x 9.

This means your answer should be 28.3. Hope this helps! Just a minor mistake (:

The formula for circumference is 2\pir, where r is equal to radius.
It states to use 3.142 for pi
It also provides you with the diameter, not the radius, so you have to divide it by two to get 4.5
2*3.142*4.5= approximately 28.278 or 28.3

Answer:

Part B: is -60 divided by -10

Part C: is The number of increments is positive.

Part D: is -1 times 60 / -1 times 10

Part E: is Any number divided by itself is 1. In the expression  -1 times 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6

Part F: is There are 6 increments of -10 feet in -60 feet.

Part G is: copy and paste -10 feet 6 times

Part H: is -60 / 4 increments

Part I: is there is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.

Part J: is -60 /4 =-15     Alex’s elevation change in each increment was -15 feet.

Step-by-Step Explaination: I did the test.

Suppose a researcher is surveying four subjects: subject A, subject B, subject C, and subject D. Subject B wants to impress the
Lina20 [59]

Answer:

Subject B.

Step-by-step explanation:

It is given that,

There are total four subjects, namely A, B, C and D.

Out of these four subjects, we have, Subject B wants to impress the researcher above everyone while the other subjects do not care.

Since, Subject B wants to impress the researcher, they would want to use any means as possible so that the researcher gets amazed by them.

For this, it is highly possible that they will start answering questions in a way that makes them impressive, which would lead them to not answer questions honestly.

While the other subjects do not care whether the researcher is impressed, this will make them give the answer honestly.

Hence, Subject B is least likely to answer the questions honestly.
