a. graduated cylinder
b. pan balance
c. tape measure
d. thermometer

B. Pan balance

Step-by-step explanation:

Which of the following tools should a scientist use to measure an object in milligrams?

The answer is : B. Pan balance

A pan balance is a device for weighing.

This device has 2 pans on a balanced beam. When these pans contain exactly the same mass the beam is in balance.

Other devices do not measure objects in milligrams.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
